• strains
  • Wolbachia strains that distort the sex ratio may alter their host's pattern of sexual selection in nature, and also engender strong selection to prevent their action, leading to some of the fastest examples of natural selection in natural populations. (wikipedia.org)
  • insects
  • That is one of the surprise discoveries made by a pair of Vanderbilt biologists when they sequenced the genome of a virus that attacks Wolbachia, a bacterial parasite that has successfully infected not only black widow spiders but more than half of all arthropod species, which include insects, spiders and crustaceans. (phys.org)
  • The researchers don't yet know exactly how Wolbachia protects the insects from human disease-causing viruses. (redorbit.com)
  • These bacteria live within numerous insects, where they specialize in manipulating their host's reproduction. (innovations-report.com)
  • To achieve this feat, Oxitec has inserted protein fragments from the herpes virus, E. coli bacteria, coral and cabbage looper moth into the insects. (mercola.com)
  • parasite
  • Use of the bacterial parasite has two potential advantages compared to other approaches: It doesn't rely on toxic chemicals and, once it is introduced, the bacteria spread rapidly through the mosquito population and sustain themselves. (phys.org)
  • On the Samoan Islands of Upolu and Savai'i, a parasite (probably Wolbachia) had been killing the male members of Hypolimnas bolina. (wikipedia.org)
  • species
  • Washington, DC -July 14, 2015- Multiple species of bacteria working together in healthy guts are responsible for keeping out nasty bacterial invader, Clostridium difficile , a hospital-acquired culprit responsible for 15,000 deaths each year. (asm.org)
  • One study concluded that more than 16% of neotropical insect species carry bacteria of this genus, and as many as 25 to 70% of all insect species are estimated to be potential hosts. (wikipedia.org)
  • Wolbachia species are ubiquitous in mature eggs, but not mature sperm. (wikipedia.org)
  • An example of a parthenogenic species is the Trichogramma wasp, which has evolved to procreate without males with the help of Wolbachia. (wikipedia.org)
  • Several host species, such as Trichogramma, are so dependent on sexual differentiation of Wolbachia that they are unable to reproduce effectively without the bacteria in their bodies, and some might even be unable to survive uninfected. (wikipedia.org)
  • In leafminers of the species Phyllonorycter blancardella, Wolbachia bacteria help their hosts produce green islands on yellowing tree leaves, that is, small areas of leaf remaining fresh, allowing the hosts to continue feeding while growing to their adult forms. (wikipedia.org)
  • Wolbachia species have been found to be endosymbionts of O. volvulus adults and microfilariae, and are thought to be the driving force behind most of O. volvulus morbidity. (wikipedia.org)
  • genomes
  • He and Senior Research Specialist Sarah Bordenstein reported the results of their study in a paper titled "Eukaryotic association module in phage WO genomes from Wolbachia" published Oct. 11 in the journal Nature Communications . (phys.org)
  • More recent research found Wolbachia-like sequences in the genomes of Acanthocheilonema viteae, some of which were transcribed in developing embryos and testes of the nematode, which suggested horizontal transfer of genetic material from an ancestral bacterial endosymbiont (McNulty et al. (wikipedia.org)
  • laboratory
  • University of Maryland investigators have now shown that a "messenger molecule" produced by the opportunistic human pathogen, Pseudomonas aeruginosa , encourages bacteria to colonize catheters in the bladders of laboratory mice, where they form biofilms. (asm.org)
  • Widespread
  • Overall, these features identify WSP as a strong candidate for future studies of host- Wolbachia interactions that affect establishment and persistence of this widespread endosymbiosis. (beds.ac.uk)
  • Trials have begun, but widespread antibiotic use is difficult to enforce and runs the risk of the bacteria subsequently adapting to the drugs. (innovations-report.com)
  • arthropods
  • Recent experimental studies have shown that the Wolbachia surface protein (WSP) can trigger host immune responses and control cell death programming in humans, suggesting a key role of WSP for establishment and persistence of the symbiosis in arthropods. (beds.ac.uk)
  • These bacteria are maternally transmitted and their presence can cause many reproductive abnormalities in arthropods such as the adzuki bean borer. (wikipedia.org)
  • found
  • Here we performed an analysis of 515 unique alleles found in 831 Wolbachia isolates, to investigate WSP structure, microevolution and population genetics. (beds.ac.uk)
  • What's more, Pearlman's group found a molecular receptor in the eye that is particularly sensitive to Wolbachia. (innovations-report.com)
  • bacterial
  • Outer membrane proteins (OMPs) of Gram-negative bacteria are key players in the biology of bacterial-host interactions. (beds.ac.uk)
  • We suspect it makes pores in the membranes of the arthropod cells that surround Wolbachia, thereby allowing the phage to overcome both the bacterial and arthropod membranes that surround it. (phys.org)
  • flies
  • On day 7 of exposure to high temperature, electron-dense bodies occur in brain cells of the flies, resembling degrading bacteria. (springer.com)
  • The flies that produced high levels of the enzyme were resistant to the Sindbis virus -- even if they weren't infected with Wolbachia . (newswise.com)
  • Protein
  • Dying microfilariae have been recently discovered to release Wolbachia surface protein that activates TLR2 and TLR4, triggering innate immune responses and producing the inflammation and its associated morbidity. (wikipedia.org)
  • host
  • They have thus been the subject of extensive studies aimed to clarify how they evolve and whether their patterns of divergence are informative about the biology of host-bacteria dynamics. (beds.ac.uk)
