Trichomoniasis

Owls can contract trichomoniasis through the ingestion of contaminated food or water, particularly from infected prey species or contaminated sources in their environment. Additionally, the parasite can be transmitted through direct contact between birds, such as during mating or feeding activities.

In some cases, infected owls may exhibit no outward signs of illness, especially during mild or chronic infections. However, in more severe cases, clinical signs may include regurgitation, difficulty swallowing, drooling, weight loss, lethargy, and dehydration. Owls with advanced trichomoniasis may also develop lesions or inflammation in the mouth, throat, or esophagus, leading to secondary complications such as aspiration pneumonia.

Direct microscopic examination of crop or esophageal swabs may reveal the presence of Trichomonas parasites or characteristic motile trophozoites. Additionally, PCR (polymerase chain reaction) testing can be used to detect the DNA of Trichomonas spp. Treatment of trichomoniasis in owls usually involves the administration of antiprotozoal medications, such as metronidazole or ronidazole.

In addition to treatment, efforts to control trichomoniasis in owl populations often focus on minimizing the spread of the parasite and reducing risk factors for infection. This may include implementing biosecurity measures to prevent contact between infected and susceptible birds, such as segregating sick individuals or disinfecting feeding and watering areas regularly.

Additionally, efforts to monitor and manage populations of intermediate hosts, such as pigeons or doves, can help reduce the prevalence of trichomoniasis in owl habitats.

Prevention of trichomoniasis in owls is essential for maintaining the health and welfare of captive and wild populations. This includes promoting proper hygiene and husbandry practices, such as providing clean food and water sources, regularly cleaning and disinfecting enclosures, and minimizing stressors that can weaken owls' immune systems and increase their susceptibility to infection. Additionally, efforts to monitor and control populations of Trichomonas reservoir hosts, such as pigeons or doves, can help reduce the risk of transmission to owls and other susceptible bird species.

It is caused by the parasite Trichomonas spp. and can lead to a range of clinical signs, including regurgitation, difficulty swallowing, and weight loss. Prevention efforts focus on minimizing the spread of the parasite and reducing risk factors for infection through proper hygiene, husbandry practices, and management of intermediate hosts. Overall, early detection, prompt treatment, and effective prevention strategies are essential for managing trichomoniasis in owl populations and preserving their health and welfare.
