Mycobacterium bovis

Contact investigation for cases of pulmonary Mycobacterium bovis.

It is treated as for any Mycobacterium bovis infection (isoniazid and rifampicin for nine months).

Other synonym: Mycobacterium bovis subsp.

He discovered in 1905 that the bovine tuberculosis bacillum, the Mycobacterium bovis, could immunize the animals without causing the disease.

All types of the M. tuberculosis began their current expansion 5000 years ago-a period that coincides with the appearance of Mycobacterium bovis.

In particular, it is not used to treat other mycobacteria; Mycobacterium bovis and Mycobacterium leprae are innately resistant to pyrazinamide.

Due to an outbreak of Mycobacterium bovis (Bovine Tuberculosis) in the founder generation, a "buffer generation" was introduced in the herd.

Mycobacterium bovis is a slow-growing (16- to 20-hour generation time), aerobic bacterium and the causative agent of tuberculosis in cattle (known as bovine TB).

This analysis of mycobacterial interspersed repetitive units also dated the Mycobacterium bovis lineage as dispersing approximately 6,000 years ago, which may be linked to animal domestication and early farming.

He came to public attention in April 2007, when a routine skin test for bovine tuberculosis (Mycobacterium bovis) tested positive, indicating he may have been in contact with the bacterium that causes the disease.

Disease caused by Mycobacterium bovis recently reemerged among children in New York City, and M. bovis is a frequent cause of TB in children in San Diego County (166,167).

On the belief that self limiting forms of tuberculosis of bovine origin in childhood protect against pulmonary tuberculosis later in life (Marfan's law), Calmette attenuated a strain of Mycobacterium bovis for use as a vaccine.

In countries where cow milk infected with Mycobacterium bovis has been eliminated (due to culling of infected cows and pasteurization), primary tuberculosis is usually caused by Mycobacterium tuberculosis and almost always begins in the lungs.

The M. tuberculosis group has a number of members that include Mycobacterium africanum, Mycobacterium bovis (Dassie's bacillus), Mycobacterium caprae, Mycobacterium microti, Mycobacterium mungi, Mycobacterium orygis and Mycobacterium pinnipedii.

The environment deemed appropriate for the denaturation of the Mycobacterium bovis was a compost of potatoes cooked in the bile of an ox treated with glycerine and Calmette reinseminated it every three weeks for thirteen years, while checking for an enfeeblement of the pathogenic power of the bacillus.

Boosting occurs when people who have had remote infection with Mycobacterium tuberculosis and/or previous exposure to Bacille Calmette-Guerin of Mycobacterium bovis (BCG), an attenuated strain of Mycobacterium bovis that is used in some countries as a vaccine against tuberculosis, are given repeated tuberculin skin tests.
