چکیده

Objetivo. Determinar la presencia de Mycobacterium avium subsp. paratuberculosis (MAP) mediante métodos serológicos, microbiológicos y moleculares, para genotipar los aislamientos MAP explorar factores asociados a seropositividad en un hato búfalos del departamento Antioquia (Colombia). Materiales métodos. Se realizó estudio transversal analizar muestras fecales suero 21 búfalas adultas asintomáticas cultivo ELISA, respectivamente. Los cultivos aislados sospechosos se confirmaron PCR MAP-IS900 (IS900-PCR). El ADN positivo volvió cuantitativo (IS900-qPCR), luego, subtipificó utilizando unidades repetitivas intercaladas micobacterias-número variable repeticiones tándem (MIRU-VNTR) repetición secuencia corta múltiples locus (MLSSR). Resultados. Al muestreo, edad promedio animales era 4.7 años, el 90.5% (19/21) eran hembras 84.2% (16/19) estaban preñadas. puntaje condición corporal fue 4.2 (escala 1 5). La producción leche 3.5 L/día/animal. No detectaron seropositivos MAP. Una hembra positiva fecal semana seis incubación luego confirmó IS900-PCR. análisis subtipado reveló que aislado correspondía al genotipo INMV 3 por MIRU-VNTR. Conclusiones. Según conocimiento autores, este es primer diagnóstico aislamiento Colombia primera vez encuentra perfil esta especie país.

Differential responses of bovine macrophages to Mycobacterium avium subsp. paratuberculosis and Mycobacterium avium subsp. avium.

Mycobacterium avium subsp. paratuberculosis and Mycobacterium avium subsp. avium are antigenically and genetically similar organisms; however, they differ in their virulence for cattle. M. avium subsp. paratuberculosis causes a chronic intestinal infection leading to a chronic wasting disease termed paratuberculosis or Johne's disease, whereas M. avium subsp. avium causes only a transient infec...

What is Mycobacterium avium subsp. paratuberculosis?

We read with interest the article by Beumer et al. (1) on the detection of Mycobacterium avium subsp. paratuberculosis in 81% of drinking water and biofilm samples by PCR. Although these findings could have a significant influence on our understanding and the potential public impact of M. avium subsp. paratuberculosis as an agent of disease, much of the information on M. avium subsp. paratuberc...

Mycobacterium avium subsp. paratuberculosis (basonym M. paratuberculosis) is the etiologic agent of a severe gastroenteritis in ruminants known as Johne's disease. Economic losses to the cattle industry in the United States are staggering, reaching $1.5 billion annually. A potential pathogenic role in humans in the etiology of Crohn's disease is under investigation. In this article, we review t...

Mycobacterium avium subsp. paratuberculosis (Map) is the etiological agent of paratuberculosis. In Chile, information about Map isolation from both domestic ruminant and wildlife species has been accumulating, but it has to be extended to other species. The present study focuses specifically on one wild grazing species, the pudu (Pudu puda), one of the less known South American deer considered ...
