Description and Significance
The smallest known species of bacterium is Mycoplasma salivarium (type strain 23064), commonly known as Asterococcus salivarius or Schizoplasma salivarium. Since they lack a cell wall, they are susceptible to several conventional antibiotics like penicillin. Binary fission allows M. salivarium to multiply, but because division is not always timed with genome replication, multinucleate filaments and various forms can emerge. They have a diameter of between 200 and 250 nm and are approximately spherical or bottle-shaped. It is thought to be a communicational organism and a component of the oral flora because it is present in practically every mouth of a healthy population.
However, Mycoplasma salivarium has also been linked to periodontal disease, septic arthritis, eye and ear diseases, and oral infections. This species has been isolated from the synovial fluid of both monkeys and people with chronic arthritis. It came from a biliary stent and was recovered. Additionally, it was found in the pleural cavity of a man who was hospitalized and did not react to the standard course of therapy with conventional antibiotics. Additionally, it has been grown from brain abscesses. It has also recently been reported as a prevalent occurrence in patients with ventilator-acquired pneumonia, a severe illness that can occur in ICU patients, and it may have a role in reducing the immune response to other pathogens, allowing opportunistic infections to develop.
Genome Structure
Describe the size and content of the genome. How many chromosomes? Circular or linear? Other interesting features? What is known about its sequence?
Cell Structure, Metabolism and Life Cycle
Interesting features of cell structure; how it gains energy; what important molecules it produces.
Ecology and Pathogenesis
Habitat; symbiosis; biogeochemical significance; contributions to environment.
If relevant, how does this organism cause disease? Human, animal, plant hosts? Virulence factors, as well as patient symptoms.
