“…The present study is apparently the first report of the occurrence of a Trichomonas in the upper digestive tract of turkey and pigeons in the southeast of Iran. In previous studies in Iran, Borji et al (2011) reported 37.32 % infection with trichomoniasis in affected pigeons of Khorasan province (Borji et al 2011). In other report from Ahvaz, Iran, Mayahi et al (2007) studied trichomoniasis in pigeons and domestic hens and detected Trichomonas from affected pigeons, but domestic hens not infected with T. gallinae (Mayahi et al 2007).…”

In June 2010, in small flock of turkeys (n = 45) that co-bred with domestic hens (n = 30) and pigeons (n = 35), a disease occurred with the clinical signs of pendulum crop, in appetence and loppy wings. Disease had morbidity (10.3 %) and mortality (6/6 %). Three carcasses and two ill turkeys were referred to the Veterinary clinic in Zabol region for diagnosis and treatment of disease. At necropsy, the oral cavity/crop small yellowish-white masses were characterized. Necrosis in mucosal of crop to gizzard increased and in the crop smelly yellowish green secretions were characterized. According to clinical and necropsy, strong suspicion to trichomoniasis was very high so for perfect diagnosing samples were taken from dead and live turkeys. Samples were taken from oral cavity, esophagus and crop mucous membranes indicated Trichomonas spp infection. 9 out of 45 pieces of turkey (20 %), 23 out of 35 pieces pigeons (65.7 %) were infected but the domestic hens were not contaminated. The result of this study indicates that tricomoniasis can be an important disease of turkeys in Iran co-bred with pigeons and domestic hens.

“…15 The degree of change and virulence of pathological strains was low to high heterogeneity of T. gallinae causes trichomoniasis. 16 Infiltration of the trachea and lungs is associated with a severe inflammatory response to the surrounding tissue. 17 Cytopathological analysis revealed many pyriform protozoa, compatible with Trichomonas gallinae.…”

Background: Trichomonas gallinae is a protozoa that causes trichomoniasis which is common found in pigeons and it attacks the digestive tract of pigeons. Proper examination can be done to differentiatefrom healthy pigeons. Purpose: to observe the changes in histopathological images of the esophagus and the crop of pigeons (Columba livia) that infected with Trichomonas gallinae. Method: Observations were carried out on 20 pigeons with symptoms of presenceTrichomonas gallinae. Swab examination in the esophagus with the Natif Test and Giemsa Staining. Esophagus and cropwas collected through necropsy in the upper digestive tract. Then histopathological examination was performed with Hematoxylin Eosin (HE) staining. Data was analyzed descriptively. Result: Histopathological features of pigeons (Columba livia) infected with Trichomonas gallinae were different from healthy pigeons. Pigeons infected with protozoa Trichomonas gallinae showed changes of the esophagus in the form of erosion and cell necrosis in stratified non-keranitized epithelium (mucosa) and infiltration of inflammatory cells in the mucosa layer and sub esophageal mucosa. In addition, changes in the crop were cell necrosis in the mucosa layer, infiltration of inflammatory cells in the submucosal layer, and congestion in the sub mucosal cavity. Conclusion: There werehistopathological changes in the esophagus and crop of pigeonsthat infected with Trichomonas gallinae.

“…In the center of Iran, [35] performed a study on pigeons in which the total prevalence rate of T. gallinae was 70.09%. In a study conducted by [36] recorded infection of Columba livia collected in various locations in Khorasan province, Iran, the prevalence of T. gallinae was 37.32%, and in Isfahan, Iran. [36] recorded the prevalence 57% of T. gallinae in (Columba livia domestica) from January to June 2010.…”

were infected with T. gallinae protozoon parasite. In the present study it was found that the two examined bird species were infected with this protozoon and there was a gradual rise in prevalence of infection from beginning to end of the study. Small variations in the prevalence rate of T. gallinae infection between doves (20.42%) and domestic pigeons (23.36%) were observed but this variation not reached to the level of statistical significance (P >0.05). It is worthy to note that in all of the infected birds in the study Trichomoniasis occurred without observation of any apparent secondary diseases or signs. In conclusion Trichomoniasis is less common in urban doves and domestic pigeons in Garmian area, Kurdistan Region-Iraq. Further research is suggested in relation to protozoan parasite in other bird species in a study will be conducted in all months of the year to find the reasons which affect the prevalence rate of infection and to estimate the parasite-host relationship.
