A serological study of twenty three European bison (Bison bonasus) derived from Northern-East Poland for the seroprevalence of Mycobacterium avium subsp. paratuberculosis, Mycoplasma bovis, Mycoplasma mycoides subsp. mycoides SC, Mycoplasma agalactiae and Mycoplasma capricolum subsp. capripneumoniae was conducted. Only specific antibodies to M. bovis were detected in two animals (8.7%) which we...

A DNA sequence differing between sheep and cattle types of Mycobacterium avium subsp. paratuberculosis was identified and used to develop a PCR test. The test unequivocally distinguished all sheep types from cattle types and was negative for a wide range of other strains from the Mycobacterium avium-Mycobacterium intracellulare complex. The test will be useful for epidemiological purposes, part...

The prevalence of Escherichia coli, Salmonella spp., and Mycobacterium avium subsp. paratuberculosis isolated from the feces of wild European starlings (Sturnus vulgaris) humanely trapped at a feedlot in central Kansas was assessed. All E. coli and Salmonella isolates recovered were tested for antimicrobial susceptibility using National Antimicrobial Resistance Monitoring System panels and the ...

We previously isolated and sequenced two genomic segments of Mycobacterium avium subsp. paratuberculosis, namely, f57, a species-specific sequence, and the p34 gene, coding for a 34-kDa antigenic protein. Comparison of sequences upstream of the p34 open reading frame (us-p34) from M. avium subsp. paratuberculosis and M. tuberculosis showed a 79-base deletion in M. tuberculosis. Sequence analysi...

We read with interest the report of Sechi et al. (1) on the associations among Crohn’s disease (CD), Mycobacterium avium subsp. paratuberculosis, and carriage of mutant alleles of the NOD2/CARD15 gene. We believe that the study by Sechi et al. was well conceived, is critical to understanding the etiology of Crohn’s disease, and should stimulate additional interest in the field. Unfortunately, t...

Mycobacterium avium subsp. paratuberculosis has been incriminated as a cause of Crohn's disease (CD); however, studies to date have been relatively small and generally only used a single diagnostic assay. The objective of the study was to reexamine the association of M. avium subsp. paratuberculosis and CD using multiple diagnostic tests. Five methods were used to detect M. avium subsp. paratub...

The present report describes the accidental detection of ectopic intestinal gland like structures with interspersed goblet cells in a mesenteric lymph node from an crossbred adult goat, which was infected with Mycobacterium avium subsp. paratuberculosis. The histomorphological features reminded intestinal epithelium, and glandular choristoma was diagnosed. This report is to our knowledge, the f...

In February 2000, Becton Dickinson Biosciences initiated a study to evaluate a potential new product, Herrold's Egg Yolk Agar with Mycobactin J and arnphotericin B, nalidixic acid, and vancomycin (BBL HEYA-MANV). The study involved laboratories which produced their own similar product, and compared the ability of the two media to support the growth of Mycobacterium avium subsp. paratuberculosis...

The infection biology of Mycobacterium avium subsp. paratuberculosis has recently crystallized, with added details surrounding intestinal invasion. The involvement of pathogen-derived effector proteins such as the major membrane protein, oxidoreductase, and fibronectin attachment proteins have been uncovered. Mutations constructed in this pathogen have also shed light on genes needed for invasi...
