Abstract

Studies on the vertical stratification of phlebotomine sandfly fauna were conducted in a non-flooded primary forest at a Tropical Forest Experimental Station of the National Institute of Amazonian Research from October 1998 to March 1999. CDC light traps were placed at one, 10, and 20 meters above ground. A total of 2,859 sandflies were captured, belonging to the Lutzomyia (99.93%) and Brumtomyia (0.07%) genera, represented by 38 species. In the Lutzomyia gender, the most frequent sub-gender was Nyssomyia (43.4%), followed by Psychodopygus (22.8%). Lutzomyia umbratilis, L. anduzei, L. rorotaensis, L. trichopyga, and L. olmeca nociva predominated at one meter above ground, while L. davisi, L. infraspinosa, L. umbratilis, L. trichopyga, and L. anduzei predominated at 10 meters. L. anduzei, L. tuberculata, L. dendrophyla, and L. dreisbachi were the most abundant species at 20 meters. L. umbratilis, which appeared at all three levels of vertical stratification, has great epidemic significance as a vector of Leishmania (Viannia) guyanensis.

Highlights

  • Resumo Caracterizou-se os gêneros de fungos miceliais encontrados em amostras de leite humano ordenhado, recebidas a partir de coleta domiciliar, pelo Banco de Leite Humano do Instituto Fernandes Figueira

  • The analyses showed the occurrence of molds and yeasts in 43 (5.2%) of the samples, with counts reaching 103CFU/ml

  • Durante a tentativa para se determinar a fonte dos fungos miceliais encontrados nas amostras de leite humano ordenhado (LHO), imaginou-se que os esporos de fungos existentes nos alimentos manipulados pelas doadoras poderiam ser a fonte de tais microrganismos para o LHO, pois, os fungos encontrados no presente trabalho eram semelhantes aos detectados por outros pesquisadores ao trabalharem com outros alimentos (Alexandre et al, 1996; Paula et al, 1988)

Summary

Introduction

Resumo Caracterizou-se os gêneros de fungos miceliais encontrados em amostras de leite humano ordenhado, recebidas a partir de coleta domiciliar, pelo Banco de Leite Humano do Instituto Fernandes Figueira. Foram analisadas 821 amostras de leite humano ordenhado, obtidas ao acaso, a partir de frascos coletados nos domicílios pelas próprias doadoras, e realizadas pesquisas de bolores e leveduras e microrganismos mesófilos.
