First report of MIRU-VNTR genotyping of Mycobacterium avium subsp. paratuberculosis isolates from Egypt
Mycobacterium avium subsp. paratuberculosis (MAP) is the causative agent of Johne’s disease, an economically important disease in ruminants worldwide. It was first isolated in Egypt in 2005. Since then, the pathogen has been detected in different Egyptian provinces. In order to trace the source of infection, genotyping using simple methods of high discriminatory power such as mycobacterial inte...
متن کاملDifferential 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...
متن کاملGenetic Structure of SSR1 & SSR2 loci from Iranian Mycobacterium Avium Subspecies Paratuberculosis Isolates by a Short Sequence Repeat Analysis Approach
Abstract Background and Objective: Paratuberculosis has been repeatedly reported from Iranian ruminant herds. The extrem fastidious nature of Mycobacterium avium subspecies paratuberculsos hinders genomic diversity studies of the pathogen. Short Sequence Repeat analysis is one of the genome-based approches recently developed to overcome this d...
متن کاملDetection of Mycobacterium avium subsp. paratuberculosis in bovine milk from the state of Pernambuco, Brazil
The aim of this study was to detect the IS900 region of Mycobacterium avium subsp. paratuberculosis (MAP) in bovine milk samples using real-time polymerase chain reaction (qPCR) and conventional PCR, and to study the agreement between these tests. A total of 121 bovine milk samples were collected from herds considered positive for MAP, from the State of Pernambuco, Brazil. MAP DNA was detected ...
متن کاملHeat inactivation of Mycobacterium avium subsp. paratuberculosis in milk.
The effectiveness of pasteurization and the concentration of Mycobacterium avium subsp. paratuberculosis in raw milk have been identified in quantitative risk analysis as the most critical factors influencing the potential presence of viable Mycobacterium paratuberculosis in dairy products. A quantitative assessment of the lethality of pasteurization was undertaken using an industrial pasteuriz...
