Mycobacterium bovis
Mycobacterium bovis (my-co-bac-te-ri-um bo-vis) is a bacteria species of the Mycobacterium tuberculosis complex (MTBC). It is a slow-growing aerobic bacterium and the causative agent of tuberculosis in cattle, also known as bovine tuberculosis.
Etymology
The name Mycobacterium bovis is derived from the Greek mykes (fungus), bakterion (small rod), and bovis (of the cow), indicating its fungal-like growth characteristics and its discovery in cattle.
Characteristics
Mycobacterium bovis is a small, non-motile, acid-fast bacillus. It is characterized by its slow growth rate and its ability to survive in a dormant state for long periods. It is also resistant to many common disinfectants and to drying, allowing it to survive in a variety of environments.
Pathogenesis
Mycobacterium bovis is primarily transmitted through the inhalation of aerosols or the ingestion of contaminated food and water. It can cause a severe form of tuberculosis in cattle, characterized by the formation of granulomas in the lungs and other tissues. It can also infect humans, causing a form of tuberculosis that is similar to that caused by Mycobacterium tuberculosis.
Treatment and Control
The primary method of controlling Mycobacterium bovis is through the testing and slaughter of infected animals. Vaccination with the BCG vaccine is also used in some countries. Treatment in humans involves a combination of antibiotics, including isoniazid, rifampicin, pyrazinamide, and ethambutol.
