  • Genomic restriction fragment analysis of diverse host and geographical panels of S. iniae isolates has shown common profiles between virulent fish and human strains, though multiple pulsed field gel electrophoresis patterns have been identified among human isolates. (wikipedia.org)
  • pathogenic bacteria
  • The sortases are thought to be good targets for new antibiotics as they are important proteins for pathogenic bacteria and some limited commercial interest has been noted by at least one company. (wikipedia.org)
  • Although it is not completely clear what causes different people to develop different diseases as a result of infection with the same pathogenic bacteria, it is suspected that host phenotypic and epigenetic factors are the source of such variation. (wikipedia.org)
  • Antibodies
  • In particular, these macrophages are activated when bacteria are bound by IgG antibodies (IgG1 or IgG3) or the complement component C3b. (wikipedia.org)
  • These types of antibodies and complement are immune substances called opsonizers, molecules that bind to the surface of bacteria to facilitate phagocytosis. (wikipedia.org)
  • The headlines are based on a paper [ 01 ] that reported that, in mice genetically altered to lack a sugar (Neu5gc) that humans also lack, feeding Neu5gc and injecting anti-Neu5gc antibodies generates inflammation which can promote the growth of cancers. (perfecthealthdiet.com)
  • virulence
  • As other virulent bacteria, GBS harbours an important number of virulence factors, the most important are the capsular polysaccharide (rich in sialic acid), and a pore-forming toxin, β-haemolysin. (wikipedia.org)
  • The GBS capsule is probably the key virulence factor because it helps GBS escape from the host defence mechanisms interfering with phagocytic killing of GBS by human phagocytes. (wikipedia.org)
  • Aeromonas
  • Among the disease organisms that cause mortality in tilapia are bacteria such as Flavobacterium columnare, Edwardsiella tarda, Aeromonas spp. (omicsonline.org)
  • allowing Gram-negative
  • Type VI secretion systems (T6SSs) are molecular nanomachines allowing Gram-negative bacteria to transport and inject proteins into a wide variety of target cells 1,2 . (jove.com)
  • kinds of bacteria
  • On Wednesday the CDC published a report by the Centre for Environment, Fisheries & Aquaculture Science in the United Kingdom, which studied the kinds of bacteria carried by the Garra rufa, or "doctor fish," an inch-long silver carp native to Southeast Asia. (medicalxpress.com)
  • It's no secret that water provides a fertile breeding ground for all kinds of bacteria. (medicalxpress.com)
  • After an outbreak of strep bacteria last year in a shipment of the fish, the British government seized five containers from London's Heathrow Airport to study what kinds of bacteria the fish were carrying. (medicalxpress.com)

  • genome
  • Extrapolation suggested that the gene reservoir in the S. agalactiae pan-genome is vast and that new unique genes will continue to be identified even after sequencing hundreds of genomes. (wikipedia.org)
  • proteins
  • Capsules made of polysaccharides (sugars) permit bacteria to evade phagocytosis by macrophages alone, since only proteins are directly recognized by macrophages in phagocytosis. (wikipedia.org)
  • So humoral immunity in forms of IgG and complement proteins is the human immune system's response against bacterial capsules. (wikipedia.org)
