“…A possible source of infection in area A may have been the use of chickens (Gallus gallus) for incubation of the eggs of the ducks to increase hatching rate during the natural breeding phase; in this way, the ducklings could have become infected after the hatching of the eggs. This fact was mentioned by SCHULZE et al (2012), who reported that infection with Cryptosporidium baileyi in a group of ducklings (Mergus serrator) in a zoo in Germany could possibly have occurred through the interaction with other species of resistant ducklings that dwelled the same environment, as well as by adult mallard ducks (Anas platyrhynchos) that were used in the incubation of eggs of red-breasted merganser (Mergus serrator) to increase hatching rate during the natural breeding phase.…”

Cryptosporidiosis is considered an infection with impact on animal health. It has been associated with high morbidity and mortality rates, leading to significant economic losses to the poultry industry. This study investigated the presence of Cryptosporidium spp. in domestic ducks of family Anatidae (Cairina moschata) from two rustic commercial aviaries located in the city of Rio de Janeiro, Brazil. A total of 315 fecal samples were collected from domestic ducks in two different areas (N=186 in area A and N=129 in area B). The microscopic analysis was conducted using a sugar centrifugal flotation technique for the identification of Cryptosporidium spp. oocysts, followed by PCR/sequencing analyses of the partial sequence of the 18S rDNA gene to determine the Cryptosporidium species. Of the 315 samples collected, only 10 (186/5.38%) from area A were positive for Cryptosporidium. The nucleotide sequence and phylogenetic analyses identified that all samples were identical (100%) and belonged to Cryptosporidium baileyi species, which is closely related to gastric species and of importance in animal health.
