Abstract

Pigeons have been considered the reservoirs for infectious agents of public health concern. The deposition of their excreta in public areas can cause environmental contamination, including the food products for human consumption. The purpose of the present study was to investigate the occurrence of Cryptococcus spp and parasites in pigeon excrements. From January to September 2006, sixty eight pools of excreta samples were collected from four public areas of Ribeirão Preto, SP. For detecting Cryptococcus spp, each sample was suspended in saline solution with chloramphenicol, and then cultured on Sabouraud Dextrose Agar plates (SDA) supplemented with chloramphenicol. The cultures were incubated at 30°C and daily observed for seven days. Cryptococcus spp-suggestive colonies were streaked on SDA medium for phenotypic identification. For searching the parasites the spontaneous sedimentation and centrifugal fluctuationin zinc sulfate techniques were carried out. Coccidian oocysts were investigated by formalinether concentration and modified Ziehl-Neelsen staining techniques. Cryptococcus spp was found in 75%, and parasites in 32% of the samples, and the concomitant presence of both pathogens has occurred in 25% of total samples. It is emphasized the establishment of strategies for preserving the public areas by reducing the pigeons populations, in order to avoid environment contamination.
