Latest Rickettsiales Stories
Certain bacteria have learned to manipulate the proportion of females and males in insect populations. Now Uppsala University researchers have mapped the entire genome of a bacterium that infects a close relative of the fruit fly.
By Jeremy Higgins, McAlester News-Capital, Okla. Jul. 4--Summertime means no school and lots of time for fun in the sun for most people. The summer months also bring out insects and other pests that could be hazardous to your health.
By Fallon, Ann M Abstract In vitro production of the obligate intracellular bacterium, Wolhachia pipientis, is essential to its manipulation as a genetic tool to spread transgenes within vector populations.
Scientists at the University of Rochester and the J. Craig Venter Institute have discovered a copy of the genome of a bacterial parasite residing inside the genome of its host species.
Wolbachia is a genus of bacteria which infects arthropod species, including a high proportion of insects (~60% of species). It is one of the world's most common parasitic microbes and possibly the most common reproductive parasite in biosphere. Studies have suggested that 25-70% of all insect species are estimated to be potential hosts. Marshall Hertig and Burt Wolbach first identified the bacterium in 1924 in a species of mosquito. Hertig described the genus as Wolbachia pipientis. Not...
Rickettsia rickettsii is a gram-negative bacterium native to the New World and causes the malady known as Rocky Mountain spotted fever (RMSF). It is transmitted through the bit of an infected tick when it feeds on animals and humans. Humans are not necessary hosts in the rickettsia-tick life cycle but they can be. S. Burt Wolbach created the first detailed description of the etiologic agent in 1919. He recognized it as an intracellular bacterium seen most frequently in endothelial cells....
