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).It is related to Mycobacterium tuberculosis, the bacterium which causes tuberculosis in humans.
Tuberculosis is spread from one person to the next through the air when people who have active TB in their lungs cough, spit, speak, or sneeze. [1] [9] People with latent TB do not spread the disease. [1] Active infection occurs more often in people with HIV/AIDS and in those who smoke. [1]
An infectious disease agent can be transmitted in two ways: as horizontal disease agent transmission from one individual to another in the same generation (peers in the same age group) [3] by either direct contact (licking, touching, biting), or indirect contact through air – cough or sneeze (vectors or fomites that allow the transmission of the agent causing the disease without physical ...
Jul. 10—Bovine tuberculosis, a contagious disease in animals that can infect humans, has been detected in a cow on Molokai for the first time in 25 years, according to the state Department of ...
Microbes can be transmitted through the actions of parents caring for their offspring, such as the cultivation of gut microbes through regurgitation feeding. [18] This type of vertical transmission does not always occur via the behavior of the genetic parent; instead, other members of a social or family groups may transmit the microbial ...
Cross-species transmission is the most significant cause of disease emergence in humans and other species. [citation needed] Wildlife zoonotic diseases of microbial origin are also the most common group of human emerging diseases, and CST between wildlife and livestock has appreciable economic impacts in agriculture by reducing livestock productivity and imposing export restrictions. [2]
A vertically transmitted infection is an infection caused by pathogenic bacteria or viruses that use mother-to-child transmission, that is, transmission directly from the mother to an embryo, fetus, or baby during pregnancy or childbirth. It can occur when the mother has a pre-existing disease or becomes infected during pregnancy. Nutritional ...
Some viral diseases are spread by insects - i.e. bluetongue disease is spread by midges. Psoroptic mange is a disabling skin condition caused by mites. Bovine tuberculosis is caused by a bacterium; it causes disease in humans and in wild animals such as deer and badgers. [118]
