Abstract
BACKGROUND: Prosthogonimus species is considered one of the most important pathogen parasites of poultry and wild birds because it causes defective egg formation, and deaths can be seen as a result of peritonitis. The genus Prosthogonimus is all-around and has been reported in many areas worldwide. This study is research on the presence of Prosthogonimus species, one of the most pathogen trematodes of birds, in Türkiye and wild birds. OBJECTIVE: We conducted the present study to investigate the presence and prevalence of Prosthogonimus spp. in Türkiye. METHODS: We studied 183 individuals of 62 wild bird species in the Kızılırmak Delta. Wild birds that died naturally were necropsied and searched for oviducal flukes. RESULTS: After performing our parasitological study, we found that 4/180 birds were infected with Prosthogonimus spp. Aythya ferina, Ciconia ciconia, Erithacus rubecula and Turdus philomelos were infected with Prosthogonimus pellucidus, Prosthogonimus macrorchis, Prosthogonimus cuneatus and Prosthogonimus ovatus, respectively. Prosthogonimus species was reported for the first time from Türkiye, together with all species found. CONCLUSION: The presence of Prosthogonimus species in Türkiye and wild birds was determined. We constructed a key of our found Prosthogonimus species based on their morphological characters.
