- Abstract
Zoonoses are infections or diseases that are transmitted from vertebrate animals to humans, by direct means, fomites or vectors. Among them, we find those caused by parasites such as cryptosporidiosis, trypanosomiasis, blastocystosis, giardiasis and microsporidiosis, among others. The present work shows the partial results of the search for three parasites of clinical importance, in commercialized, seized and captive birds. Two areas of high bird-human contact were sampled: busy markets and zoos in Mexico City. A total of 131 species-specific samples were collected. Within the avian groups with the highest prevalence were psittaciformes, passerines and galliformes. In addition, to find risk factors that can favor bird-human infection. Of these samples, by staining methods (Kynyoun), 12 and 15 presumptively positive samples for Cryptosporidium spp. were found for each area, respectively. For Microsporidium spp. there is a presumption (Trichrome mod. Weber) of 14 samples in zoos. For the molecular identification of Cryptosporidium spp. and Blastocystis spp., primers were designed targeting the 18s rRNA gene to perform endpoint PCR. For Microsporidium spp., primers already designed by other authors are being used to carry out multiplex/nested PCR, together with the use of restriction enzymes for species identification. It is expected to associate the sequencing results with human genotypes and understand the impact of birds on the ecoepidemiology of these parasites.
