ChatGPT

  1. rickettsia

    Rickettsia is a genus of non-motile, gram-negative, non-spore-forming, highly pleomorphic bacteria that can present as cocci, rods or thread-like. These bacteria are obligate intracellular parasites, meaning they can only survive within the cells of their hosts - usually invertebrates like arachnids and insects, and mammals including humans. Rickettsia species cause diseases such as typhus and Rocky Mountain spotted fever in humans, which are usually transmitted through the bite of infected insects or ticks.

  1. Rickettsia

    Rickettsia is a genus of non-motile, Gram-negative, non-sporeforming, highly pleomorphic bacteria that can present as cocci, rods or thread-like. Being obligate intracellular parasites, the Rickettsia survival depends on entry, growth, and replication within the cytoplasm of eukaryotic host cells. Because of this, Rickettsia cannot live in artificial nutrient environments and are grown either in tissue or embryo cultures. In the past they were positioned somewhere between viruses and true bacteria. However unlike Chlamydia, Mycoplasma, and Ureaplasma, Rickettsial organisms possess true cell walls similar to other gram-negative bacteria. The majority of Rickettsia bacteria are susceptible to antibiotics of the tetracycline group. Despite the similar name, Rickettsia bacteria do not cause rickets, which is a result of vitamin D deficiency. Rickettsia species are carried by many ticks, fleas, and lice, and cause diseases in humans such as typhus, rickettsialpox, Boutonneuse fever, African tick bite fever, Rocky Mountain spotted fever, Flinders Island spotted fever and Queensland tick typhus. They have also been associated with a range of plant diseases. The name rickettsia is often used for any member of the Rickettsiales. They are one of closest living relatives to bacteria that were the origin of the mitochondria organelle that exists inside most eukaryotic cells.
