Investigation of Enteric Parasites with a Focus on Zoonotic Parasites in the Feces of Galliformes.

Galliformes have a global distribution and are bred by humans as domestic animals or game birds. The world's poultry population is increasing due to high consumer demand for poultry products. Due to the increasing growth of Galliformes breeding, this study aimed to investigate gastrointestinal parasites in the feces of some species of Galliformes. In the present study, 100 distinct fecal samples were collected from seven different Galliformes species, including rural chickens, peacocks, partridges, pheasants, turkeys, quails, and guinea fowls. Sampling of each bird was performed separately, and these birds were kept in cages. In order to identify gastrointestinal parasites, the samples were evaluated using the Clayton-Lane method, the Modified Ziehl-Neelsen, and the Trichrome staining methods. Among 100 birds sampled, 53% were positive for gastrointestinal parasites. Moreover, 30%, 18%, and 5% of birds were infected with Eimeria spp., nematodes, and Giardia spp., respectively. The highest rate of parasitic infestation in Galliformes was related to protozoan infections, and the highest rate of protozoan infection was related to Eimeria (30%). In addition, complex infestation was not detected. Considering that most parasitic infections have been detected in apparently healthy birds, it is recommended to observe hygiene to regularly disinfect cages and reduce the density of birds in the nests. Due to the zoonotic potential of Giardia and the contamination of some birds with this parasite, this issue should be considered by public health officials, bird sellers' markets, owners, and breeders of these birds.
