Airsacculitis Caused by Enterobacteria and Occurrence of Eggs of the Superfamily Diplotriaenoidea in Feces of Tropical Screech Owl (Megascops choliba) in the Amazon Biome

SIMPLE SUMMARY: Owls are widely distributed globally, and Megascops choliba, the tropical screech owl, is one of the most common species. There are reports of parasitic and bacterial infections in several species of raptors. However, information about infectious diseases in owls still needs to be ma...

description SIMPLE SUMMARY: Owls are widely distributed globally, and Megascops choliba, the tropical screech owl, is one of the most common species. There are reports of parasitic and bacterial infections in several species of raptors. However, information about infectious diseases in owls still needs to be made available, especially for this species, as most articles focus on its biology. This paper reports a case of airsacculitis caused by enterobacteria and the presence of eggs of the Diplotriaenoidea superfamily in M. choliba, which, as far as we know, has not been reported in the Brazilian and international literature so far. The clinical picture is described, including the therapy used, complementary exams, necropsy results, and histopathological findings. ABSTRACT: This study aims to report the clinical signs, therapeutic strategy, necropsy results, and histopathological findings of airsacculitis caused by enterobacteria and the occurrence of eggs from the superfamily Diplotriaenoidea in the feces of Megascops choliba in the Amazon biome. A tropical screech owl nestling was rescued and admitted for hand-rearing. The animal was kept hospitalized for five months. It was fed a diet based on Zophobas morio larvae and thawed chicken breast meat with vitamin and mineral supplements. On the 37th day of hacking training for release, the owl showed weakness, lack of appetite, regurgitation, cachexia, dyspnea, ruffled feathers, dry droppings in the vent and pericloaca, and diarrhea. The parasitological examination showed eggs of the Diplotriaenoidea superfamily in the feces. The therapy employed included oxytetracycline, sulfamethoxazole, mebendazole, Potenay, sodium chloride 0.9%, and Mercepton. However, five days after starting the treatment, the bird died. Upon necropsy, prominence of the keel, pieces of undigested food in the oral cavity and proventriculus, intestinal gas, and thickened and turbid air sacs were found. The microbiological analysis of air sacs identified Escherichia coli, Klebsiella pneumoniae, and Enterobacter aerogenes. Histopathological examination showed heterophilic bacterial airsacculitis.
