Isolation of Yersinia enterocolitica from cases of acute appendicitis and ice-cream
El Sherbini, M.; Al Agili, S.; El Jali, H.; Aboshkiwa, M.; Koha, M. ( 1999 )
Abstract

Seventy [70] appendiceal specimens and 80 ice-cream samples were analysed to detect Yersinia enterocolitica using three different media. Both Y. enterocolitica and Citrobacter freundii were recovered in appendiceal specimens [17.1% and 8.6%] and ice-cream [26.25% and 18.75%] respectively. Thioglycollate medium was more selective and productive in isolating Yersinia. Y. enterocolitica was the major causative agent of acute appendicitis [11/25, 44%]. It was sensitive to chloramphenicol, gentamicin, tetracycline and trimethoprim- sulfamethoxazole

Serological and biochemical characteristics of virulence plasmid of Yersinia enterocolitica isolates from chicken in the Islamic Republic of Iran
Motallebi, M.; Zamani, M.R.; Saffar, B. ( 2000 )
Abstract

Pathogenic Yersinia enterocolitica harbour plasmid that is essential for virulence. We studied the characteristics of virulence plasmid using serological, biochemical and bioassay tests in Y. enterocolitica isolates of chicken using plasmid curing. Plasmid-cured isogenic derivatives [2029c and 2150c] were obtained from two isolates of Y. enterocolitica [RTCC 2029 and RTCC 2150]. The results demonstrated that plasmid-bearing isolates [2029 and 2150] were human-serum-resistant when grown at 37 ّC, but were sensitive when grown at 25 ّC, whereas plasmid-cured isolates [2029c and 2150c] were sensitive when grown at both temperatures. Also autoagglutination, calcium-dependency tests and experimental infection in mice demonstrated that these phenotypes were associated with the virulence plasmid
