molecular epidemiology of mycobacterium bovis in texas and mexico.seventy-nine mycobacterium bovis isolates recovered from mexican and texas cattle were categorized into 16 and 25 distinct types on the basis of is6110 and direct-repeat fingerprint patterns, respectively. by using a combination of both fingerprint patterns, 30 distinct restriction fragment length polymorphism types were defined. fifty-eight of 79 isolates (73%) were distributed among nine clusters. clustered isolates were identified within herds, as well as in geographically disperse herds in t ...19968862559
detecting emerging strains of tuberculosis by using spoligotypes.the w-beijing strain of tuberculosis has been identified in many molecular epidemiological studies as being particularly prevalent. this identification has been made possible through the development of a number of genotyping technologies including spoligotyping. highly prevalent genotypes associated with outbreaks, such as the w-beijing strain, are implicitly regarded as fast spreading. here we present a quantitative method to identify "emerging" strains, those that are spreading faster than the ...200617015836
comparison of an esat-6/cfp-10 peptide-based enzyme-linked immunospot assay to a tuberculin skin test for screening of a population at moderate risk of contracting tuberculosis.screening for latent tuberculosis infection (ltbi) with the mantoux tuberculin skin test (tst) has many limitations including false-positive results due to mycobacterium bovis bacillus calmette-guérin (bcg) vaccination. three hundred ninety adult inmates with normal screening chest radiographs in a county jail were evaluated for ltbi using tst and an esat-6/cfp-10 peptide-based enzyme-linked immunospot assay (t-spot.tb). ltbi prevalence rates were 19.0% and 8.5% by t-spot.tb and tst, respectivel ...200717442844
Absence of Mycobacterium bovis in feral swine (Sus scrofa) from the southern Texas border region.Free-ranging wildlife, such as feral swine (Sus scrofa), harbor a variety of diseases that are transmissible to livestock and could negatively impact agricultural production. Information is needed regarding the exposure and infection rates of Mycobacterium bovis and many other diseases and parasites in feral swine occurring in the Texas border region. Our main objective was to determine exposure rates and possible infection rates of M. bovis in feral swine by opportunistically sampling animals f ...201122102669

mycobacterium bovis infection in humans and cats in same household, texas, usa, 2012.mycobacterium bovis infection of cats is exceedingly rare in regions where bovine tuberculosis is not endemic. we describe the diagnosis and clinical management of pulmonary m. bovis infection in 2 indoor-housed cats and their association with at least 1 m. bovis-infected human in texas, usa, in september 2012.201525695666
failure to identify non-bovine reservoirs of mycobacterium bovis in a region with a history of infected dairy-cattle herds.the state of texas had the most (cumulative) tuberculous cattle herds of any state in the united states during the decade ending in 1997. of the cumulative 18 infected herds in texas, 12 herds were concentrated in el paso county (designated the 'el paso milkshed'). to identify whether non-bovine reservoirs were a source of mycobacterium bovis infection of cattle in this region, an investigation was conducted on the premises of 14 dairy herds (12 tuberculous and 2 non-affected herds) between may ...200010665951
