Specific detection of Mycobacterium paratuberculosis by DNA hybridisation with a fragment of the insertion element IS900.
This paper describes the evaluation of a newly developed DNA probe for Mycobacterium paratuberculosis. DNA probe PCR278 is a 278 bp fragment obtained by polymerase chain reaction (PCR) amplification of the 5'-region of IS900, an insertion element contained in the genome of M paratuberculosis. This DNA probe can specifically distinguish M paratuberculosis from a wide range of other organisms, in...
متن کاملIS900 Restriction Fragment Length Polymorphism (RFLP) Analysis of Mycobacterium avium subsp. paratuberculosis Isolates from Goats and Cattle in Norway
In Norway, paratuberculosis has been frequently diagnosed in goats, while cattle have been almost free of the infection. This difference in prevalence between goats and cattle has led to speculations about the existence of a Mycobacterium avium subsp. paratuberculosis (M. a. paratuberculosis) isolate that is non-pathogenic for cattle. There is little information available on genotypic variation...
متن کاملGenomic comparison of Mycobacterium avium subsp. paratuberculosis sheep and cattle strains by microarray hybridization.
Microarray-based comparisons of three Mycobacterium avium subsp. paratuberculosis isolates, including one sheep strain and two cattle strains, identified three large genomic deletions in the sheep strain, totaling 29,208 bp and involving 24 open reading frames. These deletions may help explain some of the differences in pathogenicity and host specificity observed between the cattle and sheep st...
متن کاملMolecular characterization of Mycobacterium bovis isolates from Ethiopian cattle
BACKGROUND Bovine Tuberculosis (BTB) is a widespread and endemic disease of cattle in Ethiopia. Information relating to genotypic characteristics of Mycobacterium bovis strains affecting the cattle population in Ethiopia is limited. We carried out molecular characterization of M. bovis strains isolated from BTB infected cattle using the spoligotyping technique. The relationship between distribu...
متن کاملDetection of Mycobacterium avium subsp. paratuberculosis in the mesenteric lymph nodes of goats by PCR and culture
The efficacy of bacterial cultures and IS900-specific polymerase chain reaction (PCR) was compared for the detection of Mycobacterium avium subsp. paratuberculosis (MAP) from the mesenteric lymph nodes of goats. Samples were collected from 75 goats slaughtered in Ilam, in southwest of Iran. Tissue homogenates were inoculated onto four media. The genomic DNA was extracted directly from mesenteri...
