RESUMO

PURPOSE: This study aimed to investigate the occurrence of leishmaniasis in domestic rabbits (Oryctolagus cuniculus) in the state of Sergipe, Brazil, and to evaluate the associated clinical signs. METHODS: A total of 31 rabbits from urban and rural areas were clinically examined using cytological, immunological, and serological tests. Blood and cytological samples were collected and analysed for the presence of Leishmania parasites and antibodies. Immunochromatographic tests were used to screen for anti-Leishmania antibodies, and cytological analysis of skin lesions was performed to detect the presence of Leishmania amastigotes. RESULTS: Of the rabbits tested, 19.35% were reactive in the anti-Leishmania antibody screening, and 3.33% tested positive for Leishmania amastigotes in skin lesion cytology. Clinical signs included cachexia, lymphadenomegaly, dehydration, apathy, dermatitis, ophthalmopathy, and alopecia. Cytological analysis revealed pyogranulomatous inflammation with Leishmania amastigotes present. The findings suggest that leishmaniasis is present among domestic rabbits in this region CONCLUSION: This study demonstrates the presence of leishmaniasis in domestic rabbits in the Northeast of Brazil. The findings underline the importance of early diagnosis and intervention in preventing the spread of the disease, and highlight the need for further research into the role of rabbits as potential reservoirs of Leishmania.
