PCR with Paracoccidioides brasiliensis specific primers: potential use in ecological studies

The precise microenvironment of Paracoccidioides brasiliensis has not yet been discovered perhaps because the methods used are not sensitive enough. We applied to this purpose the polymerase chain reaction (PCR) using three sets of specific primers corresponding to two P. brasiliensis genes. This fungus as well as several other fungi, were grown and their DNA obtained by mechanical disruption and a phenol chloroform isoamylalcohol-based purification method. The DNA served for a PCR reaction that employed specific primers from two P. brasiliensis genes that codify for antigenic proteins, namely, the 27 kDa and the 43 kDa. The lowest detection range for the 27 kDa gene was 3 pg. The amplification for both genes was positive only with DNA from P. brasiliensis; additionally, the mRNA for the 27 kDa gene was present only in P. brasiliensis, as indicated by the Northern analysis. The standardization of PCR technology permitted the amplification of P. brasiliensis DNA in artificially contaminated soils and in tissues of armadillos naturally infected with the fungus. These results indicate that PCR technology could play an important role in the search for P. brasiliensis’ habitat and could also be used in other ecological studies.

Screening for pulmonary tuberculosis in Teresópolis, RJ, Brazil: the search for respiratory symptomatic patients in emergency service of "Hospital das Clínicas de Teresópolis Costantino Ottaviano, Fundação Educacional Serra dos Órgãos"

The aim of the present study was to investigate the detection percentage of tuberculosis among patients that are respiratory symptomatic (TB suspects). In this work, we present the preliminary results of research carried out at "Hospital das Clínicas de Teresópolis Costantino Ottaviano da Fundação Educacional Serra dos Órgãos (FESO)" from November 2003 to April 2004. Among the 40 respiratory symptomatic individuals identified and referred to the Tuberculosis Control Program in Teresópolis, two (5.0%) were characterized as smear-positive. These results confirm reports in the literature and underscore the need for and importance of this strategy.

On the unknown ecological niche of Paracoccidioides brasiliensis: our hypothesis of 1989: present status and perspectives

In 1989, CONTI DÍAZ & RILLA published a hypothesis concerning the as yet unknown ecological niche of Paracoccidioides brasiliensis. The hypothesis proposed a highly efficient paracoccidioidal ecological strategy based on an important natural reservoir of the parasite, probably in heterothermic animals from fresh water environments. Further, the hypothesis proposed, a transient and variable residence in the soil with a wide aleuriospore dispersion throughout the environment together with an elevated capability of infecting humans, and domestic and wild animals. This paper analyzes scientific publications from the IX International Meeting on Paracoccidioidomycosis held in Águas de Lindoia, São Paulo, Brazil from 2-5 October 2005, providing a comparative study among this articles and with other recently published papers and the hypothesis' postulates. Since various findings and observations appear to agree with the postulates, the pursuit of novel, specific research projects in the supposed reservoirs is recommended partially or fully to confirm the hypothesis using classical laboratorial methods and modern molecular biology techniques.

American cutaneous leishmaniasis in the Pontal of Paranapanema - SP, Brazil: ecological and entomological aspects

American cutaneous leishmaniasis (ACL) occurs in epidemic outbreaks and in sporadic cases with small annual variation in the Pontal of Paranapanema, SP. There is little research on the sandfly fauna of this region. The last outbreaks were related to the Movement of the Landless Workers (MST) and with the ecological tourism in preserved forest of the Parque Estadual do Morro do Diabo (PEMD). AIM: identification of the sandfly fauna within the PEMD, mainly anthropophilic species already incriminated as vectors of ACL, as well as their seasonality, hourly frequency and data of the behavior. M&M: The captures were undertaken with CDC light and Shannon traps from 6:00 pm to 10:00 pm, monthly from May 2000 to December 2001. The temperature and relative humidity data were registered at hourly intervals. RESULTS: The captured species were: Brumptomyia brumpti, Nyssomyia neivai, Nyssomyia whitmani, Pintomyia fischeri and Pintomyia pessoai. The P. pessoai predominated (34.39%) and N. neivai was less found (0.74%), only being captured in CDC traps. Shannon trap captured more sandflies (63.01%) than the CDC traps (36.99%). Despite the environmental degradation anthropophilic species, indicates favorable bioecological conditions for persistence of vectors and potential transmission of leishmaniasis.

High occurrence of giardiasis in children living on a 'landless farm workers' settlement in Araras, São Paulo, Brazil

Enteric parasitosis remains an important public health problem in many areas around the world including in Brazil, and it is frequently associated with poverty and lack of sanitation facilities. Research carried out over the course of a year revealed that 96.6% (28/29) of children randomly selected from a 'landless farm workers' settlement in Araras, São Paulo, aged 4 - 15 years, presented Giardia intestinalis cysts. After referral to the neighborhood Health Office, all the children received tinidazole, given as a single dose of 50 mg/kg and 12 months later, new fecal samples were collected and analyzed. Despite the low adherence to the study, a high percentage (64.3% - 9/14) of the children remained positive for the parasite. This study showed a high positivity of giardiasis in child residents of the settlement, even after treatment; adults were not sensitized to the study and did not collected and/or deliver children fecal samples. The precarious living conditions are consistent with a high susceptibility to parasitic diseases, suggesting that the treatment of the infected individuals without identifying and eradicating the means of contamination is simply a palliative measure.

Epidemia de febre do Oropouche em Serra Pelada, município de Curionópolis, Pará, 1994

No final de novembro de 1994, o Instituto Evandro Chagas (IEC), Belém, Pará, foi notificado de um surto de doença febril na população do garimpo de Serra Pelada, município de Curionôpolis (5°35'S; 49°30'W), no Estado do Pará. Vinte amostras de soro de pessoas, com hemoscopia negativa para tnalária, foram recebidas para esclarecimento diagnóstico. Estudos laboratoriais comprovaram que os casos eram devido ao vírus Oropouche (grupo Simbu. gênero Bunyavirus, família Bunyaviridae). Esses achados, induziram d ida de um grupo de técnicos para realização de investigações ecoepidemíológicas entre 8 e 22 de dezembro. Foram coletadas 296 amostras de sangue, de 73 grupos familiares, sendo 54 para pequisa de vírus (casos febris) e 242para sorologia, bem como, procedeu-se a coleta de artrópodes hematófagos. As amostras para pesquisa de vírus foram inoculadas em camundongos recém-nascidos e os soros testados por inibição da hemaglutinação (1H) e MAC ELISA. Foram isoladas dez amostras do vírus Oropouche e obtidas seis soroconversões. Ademais, 245 (82,8%) amostras foram positivas por sorologia e 71 (97,3%) grupos familiares apresentaram pelo menos um membro positivo. Considerando a elevada positividade de anticoipos IH e IgM específica para Oropouche na população de Serra Pelada, concluímos que a epidemia foi extensa e apresentou taxa de ataque em torno de 83%, que correspondeu a infecção de cerca de 5.000 pessoas.

Reinterpretation de l'Histoire Stratigraphique et Tectonique de la Structure de Serra de El-Rei (Portugal)

Les travaux faits sur le terrain et les interprétations cartographiques de ces dernières années, montrant la pertinence des observations de Paul Choffat au siècle dernier, permettent de préciser l'échelle stratigraphique et de mieux distinguer les phases de l'histoire tectonique de la structure de Serra de EI-Rei. En attendant la publication d'une cartographie très détaillée mettant en évidence le détail des déformations tectoniques, il faut souligner la dissymétrie des deux flancs de cette structure ainsi que le rôle de certaines failles transverses. Sur son flanc nord, la série liasique, allant des dolomies du Lias inférieur au Toarcien inférieur ou moyen, est recouverte stratigraphiquement et en légère discordance par le "Lusitanien" qui remanie à sa base des éléments du Toarcien inférieur ou moyen. Sur son flanc sud, dans la partie centrale, la série stratigraphique liasique est comparable à celle de l'autre flanc, mais les dépôts du Toarcien, plus complets, sont affectés au cours de la zone à Meneghinii par des perturbations synsédimentaires avec fossiles brisés et/ou remaniés et des réductions d'épaisseur. Plus à l'Est, le Toarcien est très réduit et (tectoniquement?) en contact avec le Dogger. Au Sud-Ouest en revanche, prés de Bolhos, la série toarcienne est plus complète et couronnée par l'Aalénien inférieur, mais tronquée par un contact oblique N-S, repris par la tectonique récente. Sur ce flanc, le Bajocien inférieur est représenté mais peu épais; il est suivi par le Bajocien supérieur, le Bathonien et le Callovien très développés qui sont recouverts par un "Lusitanien" épais, très différent de celui du flanc nord. Cette série du Jurassique moyen et supérieur a été décrite dans la thèse de Christiane Ruget (1963). La structure de Serra de EI-Rei constitue une sorte de raccord E-W entre les importantes structures (diapiriques ?) méridiennes de Caldas da Rainha au NE et de Bolhos au SW. II s'agit d'une structure de tectonique distensive, en demi-graben, d'âge jurassique, qui est responsable de la dissymétrie des séries lithostratigraphiques sur ses deux flancs; au Miocène, pendant la compression bétique, cette structure a subi une inversion en constriction. Un modèle de l'évolution sédimentaire du secteur est présenté.
