A cross-sectional survey was performed on domestic pigeons (Columba liviadomestica) to evaluate the prevalence of Haemoproteus columbae and Trichomonas gallinae in West Azerbaijan Province, northwest of Iran between July 2015 and September 2016. Five hundred and sixty oropharyngeal swab smears were examined, 297 (53%) of which were identified to be positive for T. gallinae. Also, the results obtained from blood smears examination indicated that 115 (20.5%) cases were found to be infected with H. columbae. The rates of T. gallinae and H. columbae infection infemale pigeons (58.3% and 21.3%, respectively) were higher compared to those in males. There were 76 (26.1%) and 210 (72.4%) cases of H. columbae and T. gallinae infection in adolescent birds, respectively, which were higher than those in other age groups. We found high prevalence rates of H. columbae and T. gallinae infections in domestic pigeons. Therefore, more attention should be focused on controlling the spread of T. gallinae and H. columbae infection in domestic pigeons.

Prévalence des infections aux Haemoproteus columbae (Apicomplexa: Haemoproteidae) et Trichomonas gallinae (Metamonada: Trichomonadidae) chez les pigeons (Columba livia) dela province de l'Azerbaïdjan occidental (Iran)

Abstract [French]

Une enquête transversale a été réalisée sur des pigeons domestiques (Columba liviadomestica) pour évaluer la prévalence de Haemoproteus columbae et Trichomonas gallinae en Azerbaïdjan occidental, au nord-ouest de l'Iran entre juillet 2015 et septembre 2016. Sur les 560 frottis oropharyngés examinés, 297 (%53) étaient positifs pour T. Gallinae. De plus, le résultat de l'examen des frottis sanguins a montré que 115 pigeons (%20/5) étaient infectés par H. columbae. Les pigeons femelles ont montré un taux d’ infection plus élevée à T. gallinae (%58/3) et H. Columbae (%21/3) comparées aux pigeons mâles. Les taux d'infection par H. columbae et T. gallinae chez les oiseaux adolescents étaient respectivement de 76 (%26/1) et 210 (%72/4) étant les plus élevés parmi les différentsgroupes d’âge. Dans cetteétude, une forte prévalence desinfections par H. columbae et T. gallinae a été observée chez les pigeons. Par conséquent, une plus grande attention devrait être accordée à la lutte contre la propagation de T. gallinae et H. columbae chez les pigeons domestiques.
