RESUMEN
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.
RESUMEN
In northeastern Brazil, Haemonchus contortus is considered a gastrointestinal nematode with great veterinary relevance, causing reduced production, delayed development, economic losses and death of small ruminants. The objective of this study was to identify the morphometric variation and the types of vulvar appendages in H. contortus from goats in the semiarid region of Rio Grande do Norte. We used 100 units of H. contortus, from the collection of the Laboratory of Animal Parasitology of Federal Rural University of the Semi-Arid (UFERSA), where they were mounted between slide and coverslip with glycerin, to measure in micrometer ocular at 10X objective with correction factor of 1.3636. The body length of males was lower than females (p 0.05), which showed, respectively, mean ± standard deviation of 13,26 ± 1,15 e 18,32 ± 1,39 m. Regarding the type of vulvar appendage found in females, 72% were linguiforme type, 18% flat type and 10% button. These data contribute significantly to the taxonomy and differentiation of these endoparasites, especially in northeastern semi-arid region, where haemonchose has a worrisome role for raising goats.
No nordeste brasileiro, Haemonchus contortus é considerado um nematódeo gastrintestinal de grande relevância médico-veterinária, por causar queda de produção, atraso no desenvolvimento, perdas econômicas e mortes de pequenos ruminantes. O objetivo do presente trabalho foi identificar as variações morfométricas e os tipos de apêndices vulvares existentes em H. contortusprovenientes de caprinos da região semiárida do Rio Grande do Norte. Utilizaram-se 100 exemplares de H. contortus, oriundos do acervo do Laboratório de Parasitologia Animal da Universidade Federal Rural do Semiárido (UFERSA), onde eles foram montados entre lâmina e lamínula com glicerina, para mensuração em ocular micrométrica em objetiva de 10X, com fator de correção de 1,3636. O comprimento corporal dos machos foi inferior ao das fêmeas (p 0,05), os quais apresentaram respectivamente médias ± desvio padrão de 13,26 ± 1,15 e 18,32 ± 1,39 m. Quanto ao tipo de apêndice vulvar encontrado nas fêmeas, 72% foram do tipo linguiforme, 18% do tipo liso e 10% do tipo botão. Esses dados contribuem de forma significativa para a taxonomia e diferenciação desses endoparasitas, principalmente na região do semiárido do Nordeste, onde a haemonchose tem papel preocupante para a caprinocultura.
