Studies about parasitization by Cryptosporidium in great apes have been scarce and mostly conducted in captivity. The present study reports the presence of Cryptosporidium sp. in wild chimpanzees ( Pan troglodytes) from Ugalla, western Tanzania. Ugalla is one of the driest, most open, and seasonal habitats inhabited by chimpanzees. Cryptosporidium sp. was found in 8.9 % of the samples. The presence of the parasite was determined by preserving fecal samples in chemical conventional fixatives (MIF and alcohol absolute) staining them using a modified Zielh-Neelsen technique, and examining them with a light microscope. The number of fecal samples positive for Cryptosporidium was significantly higher during the rainy than during the dry season ( p < 0.005). The results showed that feces collected in the rainy season were almost three times more likely to be positive for Cryptosporidium than those collected in the dry season (OR = 2.81). Cryptosporidium detection was significantly negatively affected by highest temperatures (>28.7 °C, p < 0.001). Cryptosporidiosis can cause serious health problems in humans and its potential effect on Ugalla chimpanzees is discussed. [ABSTRACT FROM AUTHOR] |
