Natural infection of wild rodents by Schistosoma mansoni parasitological aspects

The evaluation of the role of rodents as natural hosts of Schistosoma mansoni was studied at the Pamparrão Valley, Sumidouro, RJ, with monthly captures and examination of the animals. Twenty-three Nectomys squamipes and 9 Akodom arviculoides with a shistosomal infection rate of 56.5% and 22.2% respectively eliminated a great majority of viable eggs. With a strain isolated from one of the naturally infected N. squamipes, we infected 75% of simpatric Biomphalaria glabrata and 100% of albino Mus musculus mice. The adult worms, isolated from N. squamipes after perfusion were located mainly in the liver (91.5%) and the mesenteric veins (8.5%). The male/female proportion was 2:1. The eggs were distributed on small intestine segments (proximal, medial and distal portions) and the large intestine without any significant differences in egg concentration of these segments. In A. arviculoides, the few eggs eliminated by the stools were viable and there was litlle egg retention on intestinal segments. Considering the ease to complete S. mansoni biological cycle in the Nectomys/Biomphalaria/Nectomys system under laboratory conditions, probably the same is likely to occur in natural conditions. In support to this hypotesis there are also the facts that human mansonic shistosomiasis has a very low prevalence in Sumidouro and endemicity among the rodents has not changed even after repetead treatments of the local patients. Based on our experiments, we conclude that N. squamipes has become a natural host of S. mansoni and possibly may participate in keeping the cycle of schistosomiasis transmission at Pamparrão Valley.

Interrelationship between Ectoparasites and Wild Rodents from Tijucas do Sul, State of Paraná, Brazil

Sixteen species of ectoparasites were collected from 50 wild rodents, from August 1990 to August 1991, in an area of Araucaria augustifolia forest, in the municipality of Tijucas do Sul, State of Paraná, Brazil. Ectoparasites infested 98% of the rodents, with the highest indices of infestation found in the dry-cool season. Species that occurred in single or multiple infestations were recorded. Ectoparasite/host associations were significant (p<0.01) for Gigantolaelaps wolffsohni/Oryzomys nigripes, Polygenis pradoi/Oxymycterus sp. and Amblyopinus sp./Oxymycterus sp. The following represent new host records: Polygenis (Polygenis) tripus from Akodon serrensis and Hoplopleura sciuricola from Sciurus aestuans. New geographic records are given for two species of flea and one sucking lice.

Mites (Acari: Laelapidae) associated with sigmodontinae rodents in Entre Ríos Province, Argentina

The richness, diversity, abundance and prevalence of mite species associated with sigmodontine rodents of different species in Entre Ríos province, Argentina are studied. Five of the six species of mites were reported for the first time in the study area. The richness and diversity of mites was higher on Oligoryzomys flavescens and O. delticola than on Akodon azarae. Androlaelaps rotundus was dominant and exhibited higher values of mean abundance and prevalence on A. azarae, Mysolaelaps microspinosus on O. flavescens and Gigantolaelaps mattogrossensis on O. delticola.

Interrelationship between ectoparasites and wild rodents from northeastern Buenos Aires province, Argentina

Infestation parameters and indices of mites, ticks and fleas associated with wild rodents from northeastern Buenos Aires Province, Argentina, were studied. Host species similarity was also analyzed in relation to their ectoparasites. Fifty-five rodents were captured from January 2000 to March 2001. In total, 1,022 ectoparasites were collected and three ectoparasite-host associations were new records. However, this is the first study on Craneopsylla minerva wolffhuegeli infesting parameters. Ectoparasite total mean abundance and total prevalence were higher in Holochilus brasiliensis (MA = 47.7; P = 100%) and Scapteromys aquaticus (MA = 25.4; P = 95.4%), meanwhile specific richness and diversity were higher in Oligoryzomys flavescens (S = 6; H = 1.3) and Akodon azarae (S = 4; H = 1.0). On the other hand, the only individual of Calomys laucha was not parasited. S. aquaticus-H. brasiliensis, which preferred similar microhabitats, shared the same ectoparasite species (Css = 100). Whereas, A. azarae, which was mostly associated with grassland, showed the highest difference with the other hosts (Css < 0.4). Considering every ectoparasite species, H. brasiliensis showed the highest mean abundance, prevalence and preference. The results suggest that the particular characteristics of this rodent would give it better possibilities not only of being infested by ectoparasites, but also of transmitting them to its progeny.

Arthropod and filarioid parasites associated with wild rodents in the northeast marshes of Buenos Aires, Argentina

During 1995, 16 species of arthropods and 2 species of filarioids, totaling 1 287 specimens were collected from 64 wild rodents captured in the Hudson Natural Reserve, Buenos Aires, Argentina. Infestation parameters and indexes were analyzed. Host specific richness was S = 6, diversity H = 1.48, and relative density RDI = 40%. High values of parasite species richness and diversity were found on Oligoryzomys delticola (S = 9; H = 1.40), Oxymycterus rufus (S = 9; H = 1.37), and Oligoryzomys flavescens (S = 9; H = 1.28), followed by Scapteromys aquaticus (S = 6; H = 0.17), and Akodon azarae (S = 4; H = 1.20). Deltamys kempi was infested only by Androlaelaps rotundus. O. delticola and O. flavescens showed the highest similarity index (O = 74.19%), followed by O. flavescens with S. aquaticus, as a result of historical processes and shared microhabitats. Considering arthropods-filarioids associations, significant affinity was observed in Litomosoides bonaerensis with Hoplopleura travassosi, Laelaps paulistanensis, and Gigantolaelaps wolffsohni.

Prevalence of infection with hantavirus in rodent populations of central Argentina

We studied hantavirus seroprevalence and virus variability in rodent populations in Diego Gaynor, northwest of Buenos Aires province, Argentina. Rodent samplings were conducted in railroads and cropfield borders in March and July 1999, September and December 2000, and March 2001. Antibody detection was performed by an enzyme link immunosorbent assay (ELISA), using the recombinant nucleoprotein of Andes (AND) virus as antigen. Tissue samples were taken from positive antibody individuals in order to confirm the presence of hantavirus genomic material and to identify virus genotypes. Akodon azarae was the most abundant species, followed by Oligoryzomys flavescens, while Calomys laucha and C. musculinus were rarely caught. We found a rate of seroprevalence of 9.3% for a total sample of 291 A. azarae and 13.5% for 37 O. flavescens. After molecular analyses of hantavirus, we confirmed the presence of hantavirus genomic material in 16 individuals with ELISA (+) results and two individuals with ELISA (-). Four amplimers for each species were sequenced and compared to the corresponding sequences of representative hantaviruses. We identified the AND Cent Lec from three O. flavescens, and the Pergamino virus from four A. azarae and from one O. flavescens. A. azarae males had higher seroprevalence than females, and heavier individuals showed higher seroprevalence than lighter ones. We did not find seroprevalence differences according to sex in O. flavescens, although this result may have been produced by the low sample size. The lowest seroprevalence was found in a period of high rodent density, when juveniles prevailed in the population. We found higher seroprevalences than those detected in previous studies for other localities of central Argentina where cases of hantavirus pulmonary syndrome (HPS) have been reported. The presence of AND Cent Lec virus in rodent populations of the study area, which is responsible of HPS cases in central Argentina, suggests that human populations are at risk of HPS disease, although there were not reported cases of this disease until today.

Accumulation des carbohydrates chez les sexués de plusieurs espèces de fourmis en relation avec l'existence ou l'absence d'un vol nuptial

The dispersal strategy of ants generally makes use of a nuptial flight to bring together the sexes. The energy necessary to accomplish this flight comes from stored carbohydrates. However, in some species, one of the sexes does not fly and mating occurs in the nest. This is the case in Iridomyrmex humilis and Cataglyphis cursor, in which the virgin queens possess wings but not leave the natal nest. We show in this work that the winged females of these two species accumulate very little carbohydrate during the maturation period occuring between emergence and mating: expressed as a percentage of dry weight at the time of mating, the total carbohydrates reach only 3.2% in I. humilis and 2.1% in C. cursor. In contrast, the males of these species which fly, possess three to four times more carbohydrates (13.0% and 6.2%, respectively). These latter values are very similar to those found for both sexes of species employing nuptial flights, such several species of wood ants (Formica rufa, F. polyctena, F. lugubris ), Lasius (L. niger , L. flavus ) or Myrmica scabrinodis also studied here. It appears that the absence of the mating flight is associated with reduced levels of carbohydrates, specially glycogen

Impact of cannabis inhalation on driving skills in occasional smokers

Objectives: Our aim was to study the brain regions involved in a divided attention tracking task related to driving in occasional cannabis smokers. In addition we assessed the relationship between THC levels in whole blood and changes in brain activity, behavioural and psychomotor performances. Methods: Twenty-one smokers participated to two independent cross-over fMRI experiments before and after smoking cannabis and a placebo. The paradigm was based on a visuo-motor tracking task, alternating active tracking blocks with passive tracking viewing and rest condition. Half of the active tracking conditions included randomly presented traffic lights as distractors. Blood samples were taken at regular intervals to determine the time-profiles of the major cannabinoids. Their levels during the fMRI experiments were interpolated from concentrations measured by GCMS/ MS just before and after brain imaging. Results: Behavioural data, such as the discard between target and cursor, the time of correct tracking and the reaction time during traffic lights appearance showed a statistical significant impairment of subject s skills due to THC intoxication. Highest THC blood concentrations were measured soon after smoking and ranged between 28.8 and 167.9 ng/ml. These concentrations reached values of a few ng/ml during the fMRI. fMRI results pointed out that under the effect of THC, high order visual areas (V3d) and Intraparietal sulcus (IPS) showed an higher activation compared to the control condition. The opposite comparison showed a decrease of activation during the THC condition in the anterior cingulate gyrus and orbitofrontal areas. In these locations, the BOLD showed a negative correlation with the THC level. Conclusion: Acute cannabis smoking significantly impairs performances and brain activity during active tracking tasks, partly reorganizing the recruitment of brain areas of the attention network. Neural activity in the anterior cingulate might be responsible of the changes in the cognitive controls required in our divided attention task.

New host, geographic records, and histopathologic studies ofAngiostrongylus spp (Nematoda: Angiostrongylidae) in rodents from Argentina with updated summary of records from rodent hosts and host specificity assessment

To date, 21 species of the genus Angiostrongylus (Nematoda: Angiostrongylidae) have been reported around the world, 15 of which are parasites of rodents. In this study, new host, geographic records, and histopathologic studies of Angiostrongylus spp in sigmodontine rodents from Argentina, with an updated summary of records from rodent hosts and host specificity assessment, are provided. Records of Angiostrongylus costaricensis from Akodon montensis andAngiostrongylus morerai from six new hosts and geographical localities in Argentina are reported. The gross and histopathologic changes in the lungs of the host species due to angiostrongylosis are described. Published records of the genus Angiostrongylus from rodents and patterns of host specificity are presented. Individual Angiostrongylusspecies parasitise between one-19 different host species. The most frequent values of the specificity index (STD) were between 1-5.97. The elevated number of host species (n = 7) of A. morerai with a STD = 1.86 is a reflection of multiple systematic studies of parasites from sigmodontine rodents in the area of Cuenca del Plata, Argentina, showing that an increase in sampling effort can result in new findings. The combination of low host specificity and a wide geographic distribution of Angiostrongylus spp indicates a troubling epidemiological scenario although, as yet, no human cases have been reported.

Experimental infection of Rio Mamore hantavirus in Sigmodontinae rodents

This study shows an experimental spillover infection of Sigmodontinae rodents with Rio Mamore hantavirus (RIOMV). Necromys lasiurus and Akodon sp were infected with 103 RNA copies of RIOMV by intraperitoneal administration. The viral genome was detected in heart, lung, and kidney tissues 18 days after infection (ai), and viral excretion in urine and faeces began at four and six ai, respectively. These results reveal that urine and faeces of infected rodents contain the virus for at least 18 days. It is possible that inhaled aerosols of these excreta could transmit hantavirus to humans and other animals.

Structure and kinematics of the Jungfrau syncline, Faflertal (Valais, Alps), and its regional significance

The formation and structural evolution of the jungrau syncline is described, based on excellent outcrops occurring in the lotschental, in the central alps of switzerland. the quality of the outcrops allows us to demonstrate that the external massifs of the swiss alps have developed due to internal folding. The jungfrau suncline, which separates the autochtonous gastern dome from the aar massif basement gneiss folds, is composed of slivers of basement rocks with their mesozoic sedimentary cover. in the inner faflertal, a side valley of the lotschental, the 200 m thick syncline cp, roses fpir imots, the gastern massif with a reduced mesozoic sedimentary cover in a normal stratigraphic succession, two units of overturned basement rocks with their mesozoic sedimentary cover, and the overturned lower limn of the tschingelhorn gneiss fold of the aar massif with lenses of its sedimentary cover. stratigraphy shows that the lower units, related to the gastern massis, are condensed and that the upper units, deposited farther away from a gastern paleo-high, form a more complete sequence, linked to the doldenhorn meso-cneozoic basin fill. the integration of these local observations with published regional data leads to the following model. on the northern margin of the doldenhorn hbasin, at the northern fringe of the alpine tethuys, the pre-triassic crystalline basement and its mesozoic sedimentary cover were folded by ductile deformation at temperatures above 300 degrees C and in the presence of high fluid pressures, as the helveti c and penninic nappes were overthrusted towards the northwest during the main alpine deformation phase, the visosity contrast between the basement gneisses and the sediments caused the formation of large basement anticlines and tight sedimentary sunclines (mullion-type structures). The edges of basement blocks bounded buy pre-cursor se-dipping normal faults at the northwestern border of the doldenhorn basin were deformed bu simple shear, creating overturned slices of crystalline rocks with their sedimentary cover in what now forms the hungfrau syncline. the localisation of ductile deformation in the vicinity of pre-existing se-dipping faults is thought to have been helped by the circulation of fluids along the faults; these fluids would have been released from the mesozoic sediments by metamorphic dehydration reactions accompanied by creep and dynamic recrystallisation of quartz at temperatures above 300 degrees C. Quantification of the deformation suggests an strain ellipsoid with a ratio (1 + e(1)/+ e(3)) of approximately 1000. The jungfrau suncline was deformed bu more brittle nw-directed shear creating well-developed shear band cleavages at a late stage, after cooling by uplift and erosion. It is suggested that the external massifs of the apls are basement gneiss folds created at temperatures of 300 degrees C by detachment through ductile deformation of the upper crust of the european plate as it was underthrusted below the adriatic plate.

Loss of mating flight and shift in the pattern of carbohydrate storage in sexuals of ants (Hymenoptera; Formicidae)

In ants, energy for flying is derived from carbohydrates (glycogen and free sugars). The amount of these substrates was compared in sexuals participating or not participating in mating flights. Results show that in participating females (Lasius niger, L. flavus, Myrmica scabrinodis, Formica rufa, F. polyctena, F. lugubris), the amount of carbohydrates, especially glycogen, was higher than in non-participating females (Cataglyphis cursor, Iridomyrmex humilis). Similarly, male C. cursor and I. humilis which fly, exhibit a much higher carbohydrate content than do the non-flying females of these species. Furthermore, the quantity of carbohydrates stored was generally higher in males than in females for each species. These results are discussed with regard to the loss of the nuptial flight by some species of ants.

Satamayhteisön informaatiokeskus tiedonvälityksen tehostajana

Merikuljetukset ovat ylivoimaisesti tärkein kuljetusmuoto sekä maailman että Suomen tavaraliikenteessä. Tämä tekee satamista tärkeän osan globaaleja toimitusketjuja. Satamien tehtävänä on toimia solmukohtina erilaisille tavaratoimituksille ja kuljetusmuodoille. Maailmankaupan kasvun ja siitä seuranneen tavaraliikenteen lisääntymisen myötä satamat voivat muodostua pullonkauloiksi tavaratoimituksille. Tavaratoimitusten läpivienti satamien kautta edellyttää lukuisia toimijoita ja työvaiheita. Satamissa toimitusketjujen hallinnan merkitys korostuu toimijoiden ja prosessien heterogeenisyydestä johtuen. Erityisesti informaatiovirtojen hallinta on haasteellista monitahoisessa satamatoimintaympäristössä. Turun yliopiston Merenkulkualan koulutus- ja tutkimuskeskuksen (MKK) Kotkan yksikön (Merenkulun logistiikan tutkimus) Mobiilisatama-hankkeessa etsitään keinoja satamasidonnaisen meri- ja maaliikenteen hallinnan tehostamiseksi satamasidonnaista tiedonvaihtoa ja siihen osana kuuluvia tietojärjestelmiä kehittämällä. Tämä tutkimusraportti on Mobiilisatama-hankkeen ensimmäinen väliraportti. Raportissa esitetään kuvaus tyypillisestä satamasidonnaisesta tavaratoimitusprosessista erityisesti tiedonvälityksen näkökulmasta sekä kuvataan prosessiin liittyviä keskeisiä pullonkauloja ja ongelmakohtia. Raportissa on kootusti esitelty myös keskeiset Suomen satamatoimintaympäristössä nykyisin käytössä olevat informaatiojärjestelmät. Osana tutkimusta tehtiin kartoitus maailmanlaajuisesti satamien käytössä olevista Port Community System (PCS) - järjestelmistä eli satamayhteisön informaatiokeskusratkaisuista. Kartoituksella pyrittiin saamaan tietoa PCS-järjestelmien maailmanlaajuisesta määrästä, maantieteellisestä sijoittumisesta, palveluista, teknisistä toteutuksista, hyödyistä ja parhaista käytännöistä. Empiirisenä osiona raportissa kuvataan haastattelututkimuksessa esiin nousseita suomalaiseen satamasidonnaiseen tiedonvälitykseen liittyviä kehittämisideoita ja haasteita. Kirjallisuus- ja haastattelututkimuksen pohjalta raportissa analysoidaan satamayhteisön informaatiokeskuksen soveltuvuutta Suomen satamatoimintaympäristöön sekä pohditaan Suomeen soveltuvan informaatiokeskuksen sisältöä ja palveluja. Tutkimuksen tulosten perusteella satamasidonnaisessa tiedonvaihdossa on löydettävissä pullonkauloja, jotka paitsi hidastavat tavaratoimitusten käsittelyä myös kuluttavat turhia resursseja. Pullonkauloja aiheuttavat muun muassa hitaiden viestintätekniikoiden ja -tapojen käyttäminen, asiakirjojen/viestien suuri lukumäärä ja kirjavuus sekä eri toimijoiden toimintatapojen ja tietojärjestelmien yhteensopimattomuus. Satamasidonnaisten toimitusketjujen tiedonvälityksen tehostamiseksi useisiin maailmalla oleviin satamiin on perustettu kokonaisvaltaisia satamayhteisön informaatiokeskuksia (eng. Port Community System tai Port Community Information System, PCS), jotka yhdistävät satamasidonnaiset toimijat toisiinsa mahdollistaen tehokkaan tiedonvälityksen eri toimijoiden kesken (Single Window -ratkaisu). Informaatiokeskuksia on perustettu käytännössä jokaiseen globaalin kaupankäynnin piirissä olevaan maanosaan. PCS-järjestelmät näyttävät keskittyvän suuriin satamiin ja varsinkin paljon kontteja käsitteleviin satamiin (≥1 milj. TEU:ta vuodessa). Informaatiokeskuksia on perustettu erityisen paljon Länsi- Euroopassa sekä Aasian etelä-, itä- ja kaakkoisosissa sijaitseviin satamiin, joihin myös suuret konttisatamat ovat keskittyneet. Itämeren alueella PCS-järjestelmiksi luokiteltavia sataman tietojärjestelmiä vaikuttaisi olevan käytössä melko vähäisesti eikä järjestelmähankkeitakaan näyttäisi olevan juuri suunnitteilla. Kartoituksen perusteella ensimmäiset maailmalla olevat informaatiokeskukset on perustettu jo noin 30 vuotta sitten, mistä johtuen eri satamissa käytössä olevat PCS-ratkaisut eroavat toisistaan sekä tekniseltä toteutukseltaan että palvelusisällöltään. Informaatiokeskusten taustalla vaikuttavat myös kansalliset hallintokulttuurit, lait ja asetukset sekä kaupankäyntitavat, jotka ovat osaltaan vaikuttamassa eri informaatiokeskusten toimintamalliin. Suomen satamatoimintaympäristössä on viimeisten parinkymmenen vuoden sisällä otettu käyttöön lukuisia merenkulkua ja satamatoimintoja helpottavia ja tehostavia tietojärjestelmiä. Monet näistä järjestelmistä ovat merenkulkuun liittyviä viranomaisjärjestelmiä, joiden tarkoituksena on muun muassa mahdollistaa turvalliset tavarakuljetukset Itämerellä alusten ja tavaralastien seurannan avulla. Tämän lisäksi yrityksillä ja muilla satamasidonnaisilla toimijoilla on käytössä kaupallisia toiminnanohjausjärjestelmiä ja muita informaatioratkaisuja. Suomen satamayhteisössä käytössä olevista kehittyneistä informaatiojärjestelmistä huolimatta informaatiopalvelut ovat asiakkaan näkökulmasta varsin pirstoutuneet. Suomesta puuttuu G2G-, B2G- ja B2B-palvelut sekä maaliikennepuolen palvelut yhteen kokoava yhden luukun periaatteella toimiva satamayhteisön informaatiokeskusratkaisu (Port Community System, PCS). Tutkimuksessa on hahmoteltu Suomeen mahdollisesti tulevaisuudessa toteutettavissa olevalle PCS-ratkaisulle asetettavia vaatimuksia ja järjestelmän palvelusisältöä. Suomeen visioidun satamayhteisön informaatiokeskusratkaisun tulisi olla olemassa olevia satamasidonnaisia tietojärjestelmiä ja niistä saatavia tietoja hyödyntävä järjestelmä. PCS-ratkaisun tulisi myös tukea olemassa olevia yrityskohtaisia informaatioratkaisuja. Tämän lisäksi tulevaisuuden järjestelmäratkaisun tulisi kyetä tuottamaan satamayhteisöä palvelevia lisäarvopalveluja, joita nykyiset järjestelmät eivät tuota ollenkaan tai ne ovat nykyisellään hajanaisesti löydettävissä. Mobiilisatama-hankkeen osapuolia ovat Turun yliopiston Merenkulkualan koulutus- ja tutkimuskeskuksen Kotkan yksikön ohella Kymenlaakson ammattikorkeakoulun Kymi Technology T&K -osaamiskeskittymä sekä Lappeenrannan teknillisen yliopiston Kouvolan yksikkö. Rahoittajina hankkeessa toimivat Euroopan aluekehitysrahasto ja Tekes sekä yrityksistä Cursor Oy, Kotkan Satama Oy, KYMP Oy, SE Mäkinen Oy, Steveco Oy, Suomen 3C Oy, Oy TransPeltola Ltd ja VR-Yhtymä Oy.

Correlação entre medidas ultra-sonográficas do coração e o deficit de hemoglobina em fetos de gestantes aloimunizadas

OBJETIVO: verificar a correlação entre as medidas ultra-sonográficas do coração fetal e o deficit de hemoglobina em fetos de gestantes aloimunizadas. MÉTODOS: estudo transversal, no qual foram incluídos 60 fetos de 56 mulheres aloimunizadas, com idade gestacional entre 21 e 35 semanas. Foram realizados 139 procedimentos. Antes da cordocentese para a coleta de sangue fetal, as medidas cardíacas e o comprimento do fêmur (CF) foram avaliados pela ultra-sonografia. O diâmetro biventricular externo (DBVE) foi obtido no final da diástole, com o cursor modo-M perpendicular ao septo interventricular, nas válvulas atrioventriculares, medindo-se a distância entre as partes externas dos epicárdios. A medida do diâmetro atrioventricular (DAV) foi obtida posicionando-se o mesmo cursor ao longo do septo interventricular, avaliando-se a distância entre a base e o ápice do coração. O CF foi determinado do trocanter maior à metáfise distal. Foi calculada a circunferência cardíaca (CC). Para ajustar as medidas cardíacas à idade gestacional, dividiu-se cada uma dessas medidas pela medida do CF. A concentração de hemoglobina foi determinada por espectrofotometria no sistema Hemocue®. O deficit de hemoglobina foi calculado baseado na curva de normalidade de Nicolaides. RESULTADOS: observaram-se correlações diretas e significativas entre as medidas cardíacas avaliadas e o deficit de hemoglobina. Para a predição das anemias moderada e grave, a sensibilidade e a especificidade encontradas foram, respectivamente, de 71,7 e 66,3% para a razão DBVE e CF; 65,8 e 62,4% para a DAV e CF e 73,7 e 60,4% para a CC e CF. CONCLUSÕES: nos fetos de gestantes aloimunizadas, as medidas cardíacas ultra-sonográficas avaliadas correlacionam-se diretamente com o deficit de hemoglobina.
