IDENTIFICATION OF Leishmania infantum IN PUERTO IGUAZÚ, MISIONES, ARGENTINA

 The emergence of zoonotic visceral leishmaniasis (ZVL) in Latin America is a growing public health problem. The urbanization of ZVL has been observed in different countries around the world, and there are a growing number of reports drawing attention to the emergence of this infection in new locations, as well as its increase in previously established areas of endemicity. In the city of Posadas, Misiones province, Northeastern Argentina, the transmission of ZVL associated with canines and Lutzomyia longipalpis was first reported in 2006. In the city of Puerto Iguazú, also in Misiones province, the first human case of ZVL was reported in February 2014. From 209 surveyed dogs, 15 (7.17%) were identified as positive by serological and/or parasitological methods. Amplification was observed in 14 samples and in all cases the species implicated was Leishmania infantum. To the authors’ knowledge, this is the first molecular characterization of L. infantum from dogs in this area.

Atorvastatin versus Bezafibrate in Mixed Hyperlipidaemia : Randomised Clinical Trial of Efficacy and Safety (the ATOMIX Study)

OBJECTIVE: Combined hyperlipidaemia is a common and highly atherogenic lipid phenotype with multiple lipoprotein abnormalities that are difficult to normalise with single-drug therapy. The ATOMIX multicentre, controlled clinical trial compared the efficacy and safety of atorvastatin and bezafibrate in patients with diet-resistant combined hyperlipidaemia. PATIENTS AND STUDY DESIGN: Following a 6-week placebo run-in period, 138 patients received atorvastatin 10mg or bezafibrate 400mg once daily in a randomised, double-blind, placebo-controlled trial. To meet predefined low-density lipoprotein-cholesterol (LDL-C) target levels, atorvastatin dosages were increased to 20mg or 40mg once daily after 8 and 16 weeks, respectively. RESULTS: After 52 weeks, atorvastatin achieved greater reductions in LDL-C than bezafibrate (percentage decrease 35 vs 5; p < 0.0001), while bezafibrate achieved greater reductions in triglyceride than atorvastatin (percentage decrease 33 vs 21; p < 0.05) and greater increases in high-density lipoprotein-cholesterol (HDL-C) [percentage increase 28 vs 17; p < 0.01 ]. Target LDL-C levels (according to global risk) were attained in 62% of atorvastatin recipients and 6% of bezafibrate recipients, and triglyceride levels <200 mg/dL were achieved in 52% and 60% of patients, respectively. In patients with normal baseline HDL-C, bezafibrate was superior to atorvastatin for raising HDL-C, while in those with baseline HDL-C <35 mg/dL, the two drugs raised HDL-C to a similar extent after adjustment for baseline values. Both drugs were well tolerated. CONCLUSION: The results show that atorvastatin has an overall better efficacy than bezafibrate in concomitantly reaching LDL-C and triglyceride target levels in combined hyperlipidaemia, thus supporting its use as monotherapy in patients with this lipid phenotype.

Composição da comunidade de diatomáceas periféricas do rio Jaú, Amazonas, Brasil

Foi realizado um estudo da flora perifítica de diatomáceas (Bacillariophyceae) existente no Rio Jaú, tributário do Rio Negro, Amazônia (2º57'S e 61º49'W). As coletas foram realizadas manualmente nas cheias de 1995, 1996 e 1997, e as lâminas permanentes encontram-se depositadas no Herbário FLOR, Universidade Federal de Santa Catarina. Foram identificados 60 táxons específicos e infra-específicos, distribuidos em 16 gêneros e 13 famílias. Eunotiaceae foi a família melhor representada, com 43,3% do total dos táxons inventariados, seguida de Pinnulariaceae com 21,6% e Surirellaceae com 11,6%. O gênero Eunotia destacou-se dentre os demais com 20 táxons. Eunotia e Pinnularia foram os gêneros mais abundantes da flora diatomológica e os que apresentaram maior variação morfológica. Para cada táxon identificado foi feita uma revisão de literatura que incluem diversos aspectos ecológicos.

The parasitism of Ixodes luciae (Acari: Ixodidae) on marsupials and rodents in Peruvian Amazon

In this work the infestation with I. luciae on Didelphimorphia and Rodentia in different environments of Peruvian Amazon was studied. Didelphimorphia was represented by the family Didelphidae. Specimens belonging to Caluromys lanatus, Didelphis marsupialis, Marmosops sp.2, Metachirus nudicaudatus, Philander andersoni and Philander opossum were infested with adults I. luciae and one Micoureus sp. was infested with larvae. In Rodentia, the infestation with I. luciae nymphs was restricted to Hylaeamys perenensis, Hylaeamys yunganus and Oligoryzomys microtis, while one Oecomys bicolor (all Cricetidae) was infested with larvae of this species. The few larvae were found on rodents captured in primary forest. The only significant difference (P < 0.05) in prevalence of adult ticks on Didelphimorphia was between P. andersoni and M. nudicaudatus (chi-square distribution). Adult tick distribution was significant different in P. andersoni in comparison with M. nudicaudatus, P. opossum and D. marsupialis (Kruskal-Wallis test). No significant effect of month or environment was detected in relation to adult tick infestation on Didelphimorphia. The prevalence of nymphal infestation as well as tick distribution showed that H. perenensis and H. yunganus were significantly more prone to be infested with nymphs of I. luciae than O. microtis. Prevalence of nymph infestation was higher in primary and secondary forest than rural areas while abundance was higher in secondary forest when compared with rural areas (P < 0.05). Kruskal-Wallis test showed differences (P < 0.05) for nymphal infestation during December in relation to January, March, April and June. The natural cycle of I. luciae appeared to be continuous, bound to adult tick infestation on Philander and nymphal infestation on Hylaeamys in forested environs.

Búsqueda de controladores naturales de insectos, hongos y malezas a partir de plantas nativas de Argentina

Los productos sintéticos destinados a controlar plagas y enfermedades en los vegetales han tenido un rol muy marcado en el incremento de la producción agrícola,sin embargo el uso continuo e indiscriminado de estas sustancias, ha causado enfermedades, muertes por envenenamiento, ha afectado al medio ambiente acumulándose por bioconcentración en los distintos eslabones de la cadena alimenticia, en el suelo y en el agua, siendo además responsables de la resistencia de distintas plagas y enfermedades. Bajo estas circunstancias nuevas vías de control de plagas deben ser estudiadas. En los últimos años se está retornando al uso de las plantas como fuente de pesticidas mas seguros para el medio ambiente y la salud humana en sustitución de los productos sintéticos. Numerosos componentes del reino vegetal han demostrado ser altamente tóxicos contra un amplio espectro de insectos y microorganismos, lo que puede ser aprovechado para el control de los mismos. Con el objeto de descubrir sustancias naturales pesticidas, a partir de plantas autóctonas de la zona Central de Argentina, que tengan alta probabilidad de ser incorporadas a prácticas y usos agronómicos, se propone realizar un estudio de la potencialidad pesticida de plantas de la Pcia de Córdoba, en dos etapas: 1) detección de insecticidas, herbicidas, fungicidas y bactericidas (contra dos especies por bioactividad) naturales en 80 plantas de Argentina; y 2) aislamiento bioguiado e identificación de los principios activos; caracterización de la bioactividad (espectro de acción).
