Resumo: | Caseous Lymphadenitis (CL) is an infectious disease that affects mainly small ruminants and is caused by the bacterium Corynebacterium pseudotuberculosis. The main focus of this study was to determine the seroprevalence of caseous lymphadenitis in the rural area in the city of Mossoró, RN and to evaluate the associated risk factors. Blood samples were collected from 385 goats in 13 farms around the rural area of Mossoró-RN. During the visits to the properties, a questionnaire related to the health sanitary system of the way that the animals were handled was applied and blood was collected through the venipuncture of the jugular, after previous cleanup in the region with cotton soaked in 70% alcohol and, in sterile tubes without anticoagulant. The serum was obtained by centrifugation for 10 minutes at 3000 rpm and the indirect ELISA test used the supernatant of the cp1002 strain of C. pseudotuberculosis and during the visit the questionnaire related to the hygiene sanitary system that the animals went through was carried out. Of the 385 goats’ sera tested, 90 samples (23.4%) showed positive results and 295 samples (76.6%) showed negative results and only 6 animals had clinical symptoms for LC. Of the 90 positive samples, 16 (17.6%) were male and 74 (25.2%) were female. Among the 295 (76.6%) negative samples, 75 (82.4%) were male and 220 (74.8%) were female and 6 animals presented clinical symptoms for CL. Out of the studied properties, 92.31% (12/13) were positive for Corynebacterium pseudotuberculosis, demonstrating the high dissemination of this agent in the city of Mossoró, RN. The age group between 3 and 6 years was the one with the highest seropositivity (60 animals), being 8 males and 52 females. The hygiene sanitary system performed on the animals on the properties was characterized by the absence of vaccination against CL and the isolation of the infected animals, and in 10 properties the abscesses were surgically removed, with the purulent material being disposed as follows: 7 bury, 2 burn and 1 dispose of in biological waste. Only 4 properties were performing quarantine to the newly acquired animals. It was concluded that the LC in goats in the city of Mossoró, RN is disseminated among the properties, with the majority of the animals were asymptomatic. In addition, most owners did not carry out proper animal hygiene sanitary system. |

O objetivo deste estudo foi determinar a soroprevalência da linfadenite caseosa na zona rural do município de Mossoró, RN e avaliar os fatores de risco associados. Foram coletadas amostras de sangue de 385 caprinos em 13 propriedades da zona rural de Mossoró-RN. Durante as visitas às propriedades foi realizada aplicação de questionário relacionado ao manejo sanitário dos animais e o sangue foi colhido através de venopunção da jugular, após limpeza prévia da região com algodão embebido em álcool 70 %, em tubos estéreis sem anticoagulante. O soro foi obtido por centrifugação por 10 minutos a 3000 gpm para a realização do teste de ELISA indireto utilizando o sobrenadante da cepa cp1002 de C. pseudotuberculosis. Dos 385 soros caprinos testados, 90 amostras (23,4%) revelaram resultado positivo e 295 amostras (76,6%) revelaram resultados negativos e apenas 6 animais apresentaram sintomatologia clínica para a LC. Das 90 amostras positivas, 16 (17,6%) eram machos e 74 (25,2%) eram fêmeas. Dentre as 295 (76,6%) amostras negativas, 75 (82,4%) eram machos e 220 (74,8%) eram fêmeas. Das propriedades estudadas 92,31% (12/13) foram positivas para Corynebacterium pseudotuberculosis, demonstrando a elevada disseminação deste agente no município de Mossoró, RN. A faixa etária entre 3 e 6 anos foi a que apresentou maior soropositividade (60 animais), sendo 8 machos e 52 fêmeas. O manejo sanitário dos animais nas propriedades se caracterizou pela ausência de vacinação contra a LC e do isolamento dos animais infectados, sendo que em 10 propriedades se fazia a remoção cirúrgica dos abscessos, com o descarte do material purulento realizado da seguinte forma: 7 enterram, 2 queimam e 1 descarta no lixo biológico. Apenas 4 propriedades realizavam a quarentena de animais recém-adquiridos. Conclui-se que a LC em caprinos no município de Mossoró-RN apresenta-se disseminada entre as propriedades, sendo a maioria dos animais assintomáticos. Além disso, a maioria dos proprietários não realiza o manejo sanitário adequado dos animais.Trabalho não financiado por agência de fomento, ou autofinanciadoUniversidade Federal Rural do Semi-ÁridoBrasilCentro de Ciências Agrárias - CCAUFERSABezerra, Francisco Silvestre BrilhanteBezerra, Francisco Silvestre BrilhanteSilva, Mara Thais de OliveiraVale, David Lopes doMaia Neto, Antonio Alves2022-06-06T20:28:03Z2022-06-062022-06-06T20:28:03Z2020-12-11Monografiainfo:eu-repo/semantics/bachelorThesisinfo:eu-repo/semantics/publishedVersionapplication/pdfCitação com autor incluído no texto: Maia Neto ( 2020) Citação com autor não incluído no texto: (MAIA NETO, 2021)https://repositorio.ufersa.edu.br/handle/prefix/7206porMaia Neto, Antonio Alves.
