| Description | Mycoplasma bovis is a Gram-negative, pleomorphic microbe that thrives in temperatures between 25-40°C, making it a thermotolerant organism. It is an obligate parasite, meaning it requires a host to survive, and obtains its energy through heterotrophy, relying on the breakdown of organic compounds. Specifically, M. bovis is a facultative anaerobe, capable of growing in the presence or absence of oxygen, with a preference for aerobic conditions. Its energy production occurs through the process of glycolysis, utilizing glucose as its primary energy source. M. bovis is widely distributed across the body, infecting various tissues and organs in cattle, its primary host species. It can be found in the lungs, eyes, genital tract, and mammary glands, as well as in the blood and cerebrospinal fluid. While it is primarily associated with bovine species, M. bovis has also been reported in other animals, such as goats and sheep, and even humans, although these cases are relatively rare. One of the most notable features of M. bovis is its capacity to adhere to and colonize host cells, allowing it to evade the host's immune response and establish chronic infections. Its small size, typically ranging from 200-300 nanometers in diameter, and lack of a cell wall, contribute to its ability to penetrate deep into tissues and evade detection by the immune system. M. bovis has significant economic and veterinary importance, as it is a major pathogen responsible for bovine pneumonia, mastitis, and reproductive disorders in cattle. Its diagnosis often relies on PCR, serology, and culture, with treatment typically involving antibiotics and supportive care. Notably, M. bovis has been found to have a high degree of genetic diversity, with several different serotypes identified, each with unique surface proteins and host specificity. This diversity makes it challenging to develop effective vaccines against this microbe, highlighting the need for continued research into its biology and pathogenesis. |
