BRUCELLA ABORTUS
| Class: | Alpha Proteobacteria |
| Genus: | Brucella |
| Species: | Brucella abortus |
| Description: | Brucella abortus ,are Gram-negative rod shaped bacteria that do not have flagella or pili, nor do they create capsule slime. They do produce endospores, which enable survival under long-term starvation and dessication. This heterotrophic bacterium carries out either aerobic or anaerobic respiration because it is a facultative bacterium . Thus, the bacteria can grow with or without oxygen present. In order to culture Brucella abortus, a complex medium is required, because the bacterium is a fastidious, requiring most essential nutrients to be imported into the cell from the host . Although it is a fastidious bacterium, Brucella abortus does have major biosynthetic pathways available to it. In its primary host, cattle, the metabolic pathway for the breakdown of erythritol is one that is most desirable, it is even used “preferentially to glucose”. |

| Pathogenicity: | Brucella abortus causes a disease called brucellosis, which used to be referred to as Malta Fever because it was first discovered in soldiers who were living on the island of Malta by Dr. David Bruce, for whom the pathogen gets its name. B. abortus is originally found in cattle and causes problems with fetus development and viability, but this pathogen can be passed to humans |
