Pathogenic properties of Yersinia enterocolitica.
A total of 88 isolates of Yersinia enterocolitica was examined for heat-stable enterotoxin production and ability to penetrate HeLa cells and evoke keratoconjunctivitis in guinea pigs (Séreny test) as potential pathogenic properties. All 49 isolates belonging to serotypes O:3, O:8, O:9, and O:5,27 and only 5 of 39 strains of other serotypes were HeLa positive. Séreny-positive strains were found...
متن کاملPlasmid-associated cell surface charge and hydrophobicity of Yersinia enterocolitica.
Virulent strains of Yersinia enterocolitica and their plasmidless, avirulent derivatives were examined for their cell surface properties. Increased surface charge and hydrophobicity of Y. enterocolitica were found to be associated with the possession of a 40- to 48-megadalton plasmid. These surface properties were expressed, as were other plasmid-associated properties, at 37 but not at 22 degre...
متن کاملYersinia enterocolitica.
Characteristics of the disease Infectious dose is 10–100 organisms Incubation period is 1⁄2–4 (usually 1–3) days; up to a week for S. dysenteriae 1 Illness: diarrhea with fever and nausea; sometimes toxemia, vomiting, cramps, and tenesmus; dysentery—blood and mucus in stools; may cause hemolytic uremic syndrome; most severe in infants; mild and asymptomatic infections occur Duration: 4–7 days; ...
متن کاملSurface-catalyzed amyloid fibril formation.
Light chain (or AL) amyloidosis is characterized by the pathological deposition of insoluble fibrils of immunoglobulin light chain fragments in various tissues, walls of blood vessels, and basement membranes. In the present investigation, the in vitro assembly of a recombinant amyloidogenic light chain variable domain, SMA, on various surfaces was monitored using atomic force microscopy. SMA fo...
متن کاملYersinia Enterocolitica in Cases of Diarrhea in Gorgan, Northern Iran
Abstract Background and objectives: After respiratory infection, Diarrhea is the second cause of mortality. Yersinia enterocolitica is the second important cause of infectious diarrhea in children of some countries. In this study, we evaluated the frequency of Yersinia entocolitica of diarrheal specimens in Gorgan, Iran. Material and Methods: This descriptive cross - sectional Study was carried...
