Epidemiology and pathology of <i>Trichomonas gallinae</i> in the common pigeon (<i>Columba livia</i>)

Abstract

Pigeons (n=300) were examined during July 2007 to June 2008 in different areas of Mymensingh district. Of the pigeons examined, 202 (67.3%) were infected by Trichomonas gallinae (Rivolta, 1878). Prevalence of Trichomonas gallinae was higher in female pigeon (70.9%) than male pigeon (63.8%). Adult pigeons aged >3 months were comparatively more affected (75%) than the squab aged <30 days (72.1%) and the younger aged between 30 days to 90 days (64.7%). T. gallinae infection was significantly (P<0.01) lower in summer (48.4%) than rainy (69.8%) and winter (69.3%) seasons. Pathological lesions were confined in the crop, proventriculus and liver. There was an accumulation of greenish fluid and/or cheesy material in the crop and proventriculus. At necropsy, yellowish to grayish necrotic lesions were evident in the crop and proventriculus. On the other hand, the liver became congested where congestion of sinusoids and focal accumulation of heterophils in the parenchyma were found. But, no microscopic lesions were seen in the crop and proventriculus although gross lesions were more prominent in these two organs.

First report of an outbreak trichomoniasis in turkey in Sistan, Iran

“…During this study (June 2010) 65.7 % pigeons were infected with T. gallinae which supported the findings of Begum et al (2008), De Carli et al (1979) and McKeont et al (1997), who recorded 67.3, 62.3 and 59.0 % prevalence of T. gallinae in pigeons in Bangladesh, Brazil and Australia, respectively (Begum et al 2008;De Carli et al 1979;McKeon et al 1997). But, the present finding is found higher prevalent rate than that of Villanua et al (2006), Tasca and De Carli (1999) and Toro et al (1999), who reported 34.2, 26.5 and 11 % T. gallinae infection in pigeon in Spain, Brazil and Chile, respectively (Tasca and De Carli 1999;Toro et al 1999;Villanua et al 2006).…”

Gastrointestinal helminths in pigeon Columba livia (Gmelin, 1789)

“…The values found in the present study of helminth infestation were significantly higher than those of helminth infestation of pigeon observed by Radfar et al (2011) and Natala et al (2009). So far, information on the helminth parasites of Columba livia is scanty in Bangladesh, except that of Begum et al (2008) who observed epidemiology and pathology of protozoan parasites in Trichomonas gallinae in the common pigeon (Columba livia). The present study thus provides baseline or preliminary information on the subject.…”

Prevalence of Trichomonas gallinae infection in Pigeon of Jessore District, Bangladesh

“…Several health issues will have an effect on pigeons; however, parasitic infections will play an important role. The role of pigeons in the transmission of disease to other pigeons, domestic animal, and poultry and especially to human has been well documented by many authors [2,3].…”
