Hamiltonella defensa (H. defensa) is a species of bacteria. It is maternally or sexually transmitted and lives as an
H. defensa is a member of the family Enterobacteriaceae.[4] It can be found both extracellularly and intracellulary in H. defensa itself, and also the bacteriocytes.[4] It is a gram-negative bacteria and has been found to have six distinct secretion systems that mediate the export of protein through the inner and outer membranes.[4][5] In general, "Candidatus Hamiltonella defensa's" functions are relatively unknown,[3] and the H. defensa's discovery was not specified by a particular person.
H. defensa's draft genome sequence was first discovered in the B. tabaci complex of the "Candidatus Hamiltonella defensa".
The H. defensa is significantly smaller (at 1.84-Mpb) than its bacteria relatives;
Special properties
H. defensa has two types of type-3 secretion systems (T3SS).[6] These translocation systems are typically used by pathogens to occupy host cells and elude immune responses.[6] They are also necessary for the perseverance of certain symbiosis.[6]
There have been recent studies done attempting to find ways to manipulate H.defensa's "self-fighting" qualities, and create a cure for certain illnesses.[vague][citation needed]
