Resumo: | Swine mycobacteriosis is an important cause of carcass condemnation at abattoirs. One of the best ways to recognize the etiologic agent involved, in live animals, is the fecal isolation, as 94% of the lesions are located in the digestive tract. Therefore, the goal of the present study was to compare the performance of four decontamination methods followed by inoculation in three different culture media, totalizing twelve procedures of mycobacteria search from swine fecal samples experimentally contaminated. The swine feces were artificially contaminated with 0.02 g of Mycobacterium avium, PIG-B strain, and subjected to mycobacteria isolation trial. The protocols used were: 1) modified Petroff or basic method; 2) modified Lowenstein-Jensen or acidic method; 3) modified Petroff or basic method with re-suspension in Amphotericin B; 4) modified Lowenstein-Jensen or acid method with re-suspension in Amphotericin B, followed by inoculation in Petragnani, Lowenstein-Jensen and Lowenstein-Jensen medium with antibiotics (Penicillin G and Nalidixic acid). There was a difference (p<0.05) between the mycobacterial recovery percentages from swine feces. The acid method with re-suspension in Amphotericin B solution and inoculation in Lowenstein-Jensen medium with antibiotics showed the best results (87% of mycobacteria recovery). |

Assim sendo, o presente estudo teve por objetivo comparar o desempenho de quatro métodos de descontaminação com semeadura em três diferentes meios de cultura, totalizando doze procedimentos na pesquisa de micobactérias a partir de amostras de fezes de suínos contaminadas experimentalmente. Amostras de fezes de suínos foram contaminadas artificialmente com 0,02g de Mycobacterium avium, estirpe de PIG-B, e submetidas à tentativa de isolamento de micobactérias, utilizando-se os seguintes protocolos de descontaminação: 1) Petroff modificado ou método básico; 2) Lowenstein-Jensen modificado ou método ácido; 3) Petroff modificado ou método básico e ressuspensão com anfotericina B; 4) Lowenstein-Jensen modificado ou método ácido e ressuspensão com anfotericina B; com subseqüente semeadura em meios de Petragnani, Lowenstein-Jensen e Lowenstein-Jensen com antibióticos (Penicilina G e Ácido nalidíxico). Houve diferença entre os percentuais de recuperação de micobactérias a partir das fezes de suínos (p<0,05) e o método ácido com ressuspensão em solução de anfotericina B e semeadura em meio de Lowenstein-Jensen com antibióticos apresentou os melhores resultados (87% de recuperação de micobactérias).Universidade Federal da Bahia Escola de Medicina Veterinária Departamento de Medicina Veterinária PreventivaUniversidade Federal de São Paulo (UNIFESP) Escola Paulista de Medicina Departamento de MicrobiologiaUNIFESP, EPM, Depto. de MicrobiologiaSciELOSociedade Brasileira de MicrobiologiaUniversidade Federal da Bahia Escola de Medicina Veterinária Departamento de Medicina Veterinária PreventivaUniversidade Federal de São Paulo (UNIFESP)Oliveira, Eugenia Márcia de DeusRodriguez, César Alejandro RosalesRocha, Vivianne Cambuí MesquitaAmbrosio, Simone RodriguezOhara, Patrícia MiyukiAmaku, MarcosFerreira, FernandoDias, Ricardo AugustoLeao, Sylvia Cardoso [UNIFESP]Ferreira Neto, José Soares2015-06-14T13:37:15Z2015-06-14T13:37:15Z2007-12-01info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersion687-692application/pdfhttp://dx.doi.org/10.1590/S1517-83822007000400019Brazilian Journal of Microbiology.
