Mycoplasma Haematoparvum
''Mycoplasma'' is a genus of bacteria that, like the other members of the class ''Mollicutes'', lack a cell wall around their cell membranes. Peptidoglycan (murein) is absent. This characteristic makes them naturally resistant to antibiotics that target cell wall synthesis (like the beta-lactam antibiotics). They can be parasitic or saprotrophic. Several species are pathogenic in humans, including ''Mycoplasma pneumoniae, M. pneumoniae'', which is an important cause of atypical pneumonia, "walking" pneumonia and other respiratory disorders, and ''Mycoplasma genitalium, M. genitalium'', which is believed to be involved in pelvic inflammatory diseases. ''Mycoplasma'' species (like the other species of the class ''Mollicutes'') are among the smallest organisms yet discovered, can survive without oxygen, and come in various shapes. For example, ''M. genitalium'' is flask-shaped (about 300 x 600 nanometers, nm), while ''M. pneumoniae'' is more elongated (about 100 x 1000 nanometers, ...

Mycoplasma Haemofelis
''Mycoplasma haemofelis'' (formerly ''Haemobartonella felis'') is a gram-negative epierythrocytic parasitic bacterium. It often appears in bloodsmears as small (0.6μm) coccoid bodies, sometimes forming short chains of three to eight organisms. It is usually the causative agent of feline infectious anemia (FIA) in the United States. The ~1.15 Mb genome contains a minimalistic assortment of genes limited to the most basic cellular functions. This leaves ''M. haemofelis'' inextricably dependent upon its host for the provision of amino acids, cholesterol, vitamins and fatty acids. The complex and specific conditions that the bacterium requires have made it impossible to culture outside a host thus far. Arthropod vectors are thought to be the primary source of infection, although ''M. haemofelis'' is also known to be transmitted from queen to kitten and following blood transfusion. Immunocompromization and/or coinfection with FeLV, FIV and other ''Mycoplasma'' species can exacerb ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
