In a case of rapid evolution, bacteria have been found to give whiteflies - crop-damaging insects of global importance - an edge over their uninfected peers, new research from the University of Arizona suggestsIn just six years, bacteria in the genus Rickettsia spread through a population of the sweet potato whitefly (Bemisia tabaci), an invasive pest of global importance. Infected insects lay more eggs, develop faster and are more likely to survive to adulthood compared to their uninfected...

Researchers from the University of Georgia College of Veterinary Medicine have made an "unexpected" dual discovery that could open new avenues for treating Ichthyophthirius multifiliis, or "Ich", a devastating single-celled protozoan parasite that commonly attacks freshwater fish. With the aid of whole-genome sequencing, researchers found that Ich harbors two apparently symbiotic intracellular bacteria: Bacteroides, which are usually found free-living, and Rickettsia, which are obligate...

Money spiders infected with Rickettsia bacteria are less likely to 'balloon' "“ that is, to use their silk as sails to catch gusts of wind and travel long distances. Researchers writing in the open access journal BMC Biology suggest that it may be in the bacteria's interests to ground the spiders and that this reduction in dispersal could reduce gene flow and impact on reproductive isolation within the meta-population. While working at the University of East Anglia, Sara Goodacre led an...

How do you study a pathogen that can't survive outside its host's cells? In a new study published in the open access journal PLoS Biology, Hiroyuki Ogata and colleagues show that sequencing and analyzing the genome of the bacteria Rickettsia felis provide valuable insights into the biology and behavior of this intracellular pathogen. The researchers discovered that the parasitic bacterium has the standard large circular chromosome plus two unexpected plasmids, small circular pieces of DNA...
