Preliminary test results indicate that a dairy in west Texas is infected with cattle tuberculosis (TB). Cattle TB is caused by theMycobacterium bovis<\/em> bacteria and can cause internal lesions in animals.\u00a0 Milk from commercial dairies is pasteurized, killing bacteria with heat, so there is not public health concern from this herd detection.<\/p>\n \u201cAnimals from the 2,600-head dairy were being prepared for sale and some reacted to TB skin tests. The follow-up blood tests on these animals also were positive,\u201d said Dr. Bob Hillman, Texas state\u00a0 veterinarian and executive director of the Texas Animal Health Commission, the state\u2019s livestock and poultry health regulatory agency.\u00a0 \u201cSamples were collected from two of the cattle slaughtered for examination, and the tissues were submitted to the National Veterinary Services Laboratory in Ames, Iowa for additional testing.\u00a0 The lesions are microscopically compatible with TB, and Polymerase Chain Reaction (PCR) tests on the tissues have detected the DNA, or the basic genetic material of the disease.\u00a0 The final confirmation is based on a culture, which may take several weeks. It involves identifying bacterial growth from the tissue samples as\u00a0Mycobacterium bovis<\/em>.\u201d<\/p>\n \u201cWe will be determining the dispensation of the herd in the next few days,\u201d said Dr. Hillman. \u201cAn epidemiological investigation has been launched to determine the source or possible spread of the disease.\u201d<\/p>\n Texas regained cattle TB-free status in fall 2006, after losing the coveted status in spring 2002.\u00a0 Dr. Hillman noted that one TB-infected herd will not affect the state\u2019s status, but two infected herds within a 48-month period will result in a loss of TB-free status. Texas\u2019 most recent TB-infected herd was a dairy, detected in 2004 and depopulated.\u00a0 California lost its TB-free status in September 2008, and Minnesota, Michigan and New Mexico are split states, meaning areas within these states have different TB statuses.\u00a0 All other states currently are TB-free.<\/p>\n","protected":false},"excerpt":{"rendered":" Preliminary test results indicate that a dairy in west Texas is infected with cattle tuberculosis (TB).
