Human Pathogens, Environmental Bacterium and World Records

The genus of Francisella tularensis is Francisella while the species is F. tularensis. Similar to many former(a) intracellular bacteria that tend to break out of phagosomal compartments in order to replicate in the cytosol, F. tularensis strains also produce various(a) hemolytic agents (1). This helps to facilitate the breakdown of the phagosome. Particularly, NlyA, a hemolysin protein, with simile to Pseudomonas aeruginosa HlyA was characterized in biovar novicida whereas an acid phospholipase C AcpA has been piece in other strains to act as a hemolysin(1). Even though F. tularensis does not have a acerbity secretion systems that is popular of some better-characterized pathogenic bacteria, it does have a number of adenosine triphosphate binding cassette (ABC) proteins that can be linked to the secretion of virulence factors. F. tularensis is able to survive outside of a mammalian legion for weeks(1). This bacteria can be found in water, grassland, and haystacks. F. tularensis and gum olibanum infects a number of small mammals such as voles, rabbits, and muskrats, as well as humans. Even still, there has not been a case where tularemia has been shown to transfer from human to human only instead tularemia is caused through contact with infected vectors standardised ticks, mosquitos, and deer flies or animals(1).




Thiomargarita namibiensis, with genus Thiomargarita and species T. namibiensis, can be found in the continental shelf in the ocean sediments(4). It was spy in 1999 and is still currently the largest bacterium ever discovered, with a width up to 750 μm. This makes it possible to be seen with the naked eye(4). 1 unusual adaptation of this bacterium is its reductive division pattern. In extreme conditions such as starvation, this bacterium can undergo an unusual form of division. The numbers of its cells increase, but there is no net change in volume. This division pattern is a survival strategy that increases distribution(2). This organism oxidizes hydrogen sulfide (H2S) into...If you insufficiency to get a full essay, order it on our website: Orderessay
