Macrococcus is a genus of bacteria. The type species is Macrococcus equipercicus .
features
Representatives of Macrococcus are spherical or cocci-shaped and occur in pairs, tetrads (groups of 4 cells), sometimes also individually or in chain cocci. The diameter is 0.74-2.5 µm. Macrococcus is only weakly facultative anaerobic , but shows the greatest growth under aerobic conditions. The catalase and oxidase test are positive. The genus is resistant to the bacterial protective enzyme lysozyme . The antibiotic bacitracin also has no effect. Some species reduce nitrate, e.g. B. M. caseolyticus .
This genus can be derived from Staphylococcus u. a. differentiate due to the higher GC content (38–45%), the lack of teichonic acid in the cell wall and the mostly larger cells. Furthermore Macrococcus oxidase positive, most staph negative. Macrococcus is found in the natural microfauna of horses and cattle. The species Macrococcus canis , described in 2017, is associated with infections in dogs.
