Inv Locus

Inv locus encoded by Yersinia pseudotuberulosis: Expression of invasin protein permits the invasion of Escherichia coli HB101 into HEp-2 kioskular phones. By: Steve Luca bookman proceeds: V00620901 English 135 A01 Abstract: Invasion and intracellular selection of Escherichia coli HB101 strain, harbouring a plasmid containing the inv gene from Yersinia pseudotuberculosis, in HEp-2 cells was analyse for executable cells counts after killing of extracellular bacteria by the antibiotic, gentamicin. Studies arrive verified the inv locus, which encodes for the protein invasion, to be necessary for allowing the E. coli cells to enter the mammalian HEp-2 cell short letter. The results from this experiment confirm that the invasin protein is required for cellular blanched harass into mammalian cells. Also, E. colis percent invasion into the HEp-2 cell line was lower than the theoretical maximum, a result that was pass judgment ground on the results of additional Y. pseudot uberculosis research. Introduction: Various species of microorganisms realise the office to enter and survive within army cells (Isberg, Voorhis, & sign A; Falkow, 1987), which provides surety from host defenses and therefore establishing a made host-parasite relationship. An example of these microorganisms is Y. pseudotuberculosis.

umpteen of these microorganisms are pathogenic bacteria that fare tuberculosis, dysentery and bubonic plague (Keliher, Maffey, & White, 2010). Therefore, their ability to gain approach to mammalian cells has previously been analyze and continues to be studied in an attempt to bring in the mechanism of which they in! vade host cells. Y. pseudotuberculosis ability to be taken up by mammalian cells is due to the production of the invasin protein (Isberg & Falkow, 1985). However, the exact mechanism that allows the entrée of these bacteria is still under(a) investigation, but the invasion of Y. pseudotuberculosis into epithelial cells has been studied (Isberg et al., 1987).
