  • The 5 species currently in the genus Providencia , in descending order of prevalence, include Providencia stuartii, Providencia rettgeri, Providencia alcalifaciens, Providencia rustigianii, and P heimbachae . (medscape.com)
  • The genus Nocardia is currently composed of 87 validly described species: 46 of these species are medically relevant ( 16 , 27 , 53 ). (antimicrobe.org)
  • 92. Which bacterial genus includes species responsible for causing botulism? (answerscrib.com)
  • These examples do not necessarily replicate plasmid fitness effects in natural bacterial hosts, which remain largely unexplored. (nature.com)
  • HGT often happens via plasmids, circular molecules of DNA that can replicate independently of a pathogen's other genetic material. (mpkb.org)
  • And, because of their ability to replicate on their own within hosts, plasmids are also known as replicons. (excedr.com)
  • Enterococcus species are facultative anaerobic organisms that can survive temperatures of 60°C for short periods and that grow in high salt concentrations. (medscape.com)
  • Here, we examined two well-characterized adhesins in Enterococcus faecalis , aggregation substance and endocarditis- and biofilm-associated pili, and found that they exhibit distinct functional contributions depending on the growth stage of the bacterial community. (nih.gov)
  • Pili interfere with aggregation substance-mediated clumping and plasmid transfer under planktonic conditions, whereas the two adhesins structurally complement one another during biofilm development. (nih.gov)
  • These results help to explain the high prevalence of plasmids in the greatly diverse natural microbial communities. (nature.com)
  • Moreover, genomic results showed a link between pOXA-48_K8 fitness effects and bacterial phylogeny, helping to explain plasmid epidemiology. (nature.com)
  • The particular plasmid type that contains the resistance elements is important to the epidemiology. (genomeweb.com)
  • These provide susceptibility profiles as well as species identification using non-molecular methods by essentially running a panel of biochemical tests to see what the strain can and cannot metabolize. (genomeweb.com)
  • The final plasmid construct, pBVR2, was successfully transformed into C. trachomatis strain L2-434. (oregonstate.edu)
  • Plasmid persistence in bacterial populations is strongly influenced by the fitness effects associated with plasmid carriage. (nature.com)
  • To fully understand plasmid persistence in natural bacterial populations, it will be necessary to address these limitations. (nature.com)
  • Advantage has been taken of the natural ability of Agrobacterium to transfer plasmid DNA into the nuclei of susceptible plant cells. (jrank.org)
  • Agrobacterium cells with a genetically-modified plasmid, containing a gene for the desired trait and a marker gene, usually conferring antibiotic resistance, are incubated with protoplasts or small pieces of plant tissue. (jrank.org)
  • This method has proven valuable for maize, rice, and sugar cane, species that are outside the host range for vector transfer by Agrobacterium . (jrank.org)
  • Reasons theorized include different receptor characteristics in male and female urinary tracts and a bacterial predilection for Foley catheters over condom catheters, which are used more commonly in males. (medscape.com)
  • The roles of SOD in bacterial survival and pathogenesis vary depending on the species. (bodyecology.com)
  • However, plasmid fitness effects in wild-type bacterial hosts remain largely unexplored. (nature.com)
  • In this study, we provide a detailed characterisation of the distribution of plasmid fitness effects in wild-type bacterial hosts. (nature.com)
  • Bacterial species are usually not harmful to their hosts, although there are exceptions. (frontiersin.org)
  • This article is about treatment of bacterial infection. (wikipedia.org)

  • Diseases caused by infection with Borrelia species body louse), all known species are transmitted by ticks (4). (cdc.gov)
  • Over the past decade, studies on human hosted Campylobacter species strongly suggest that Campylobacter concisus plays a role in the development of inflammatory bowel disease (IBD). (frontiersin.org)
  • Most of the studies on the human hosted Campylobacter species in the past decade were on Campylobacter concisus , this bacterium is therefore the focus of this review. (frontiersin.org)
  • They discovered that C. concisus pSma1 plasmid is associated with severe ulcerative colitis (UC) https://doi.org/10.1099/mgen.0.000457 . (edu.au)
