Staph infections that become resistant to multiple antibiotics don't happen because the bacteria themselves adapt to the drugs, but because of a kind of genetic parasite they carry called a plasmid that helps its host survive the antibiotics.
Biologists have been observing the “selfish” genetic entity segregation distorter (SD) in fruit flies for decades. Its story is a thriller among molecules, in which the SD gene destroys maturing sperm that have a rival chromosome. A new study reveals a tactic that gives SD’s villainy an extra edge.
In the twentieth century the sequencing of an entire genome of a higher (eukaryotic) organism was a truly exceptional event – by the end of the year 2000, only four such sequences were available.
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...
