Prevalence of Yersinia enterocolitica from food and pigs in selected states of Malaysia

A comprehensive review on the prevalence, pathogenesis and detection ofYersinia enterocolitica

“…produce dark colonies. 40 Phosphate buffer saline (PBS) and trypsin soybean soup (TSB) have been reported as the best media for the pre-enrichment of the samples of Y. enterocolitica. 17,41,42 However, in the culturing methods, the prolonged incubation time leads to the growth of other psychrophilic bacteria, which limits their further application.…”

“…Although three different chromogenic media, namely, Y. enterocolitica chromogenic medium (YeCM), Y. enterocolitica agar-selective chromogenic medium (YECA) and CHROMAgar (CAY) have also been developed for use in diagnostic and clinical laboratories, it was observed that CIN Agar modied with L-arginine, ferric ammonium citrate, sodium thiosulfate and DL-phenylalanine had better identication ability for Y. enterocolitica over other bacteria in food samples. 7,40,[45][46][47] Importantly, the ISO method for food samples (ISO 10273:2003) also includes the use of the PBS broth, ITC broth for pre-concentration, and CIN for plating. 48 Similarly, other developed methods, such as NMKL method No-117, NCFA, BAM-U.S. FDA, indicated the cold enrichment of Y. enterocolitica on PSB and MRB.…”

Genetic diversity, virulotyping and antimicrobial resistance susceptibility ofYersinia enterocoliticaisolated from pigs and porcine products in Malaysia

“…Yersinia enterocolitica was found in beef, shrimp and tofu from Thailand . In Malaysia, the pathogen had been isolated from raw pork, swine liver, swine intestine and pigs …”

Evaluation of a Modified Cefsulodin-Irgasan-Novobiocin Agar for Isolation of Yersinia spp

“…The IP138 strain was chosen because it is of biotype 3 and this particular biotype has been frequently reported in food and animal from Asia and Southeat Asia countries with warm climate (Southern China, Malaysia, Taiwan and Thailand) [30], [31], [32], [33]. The ratio of LOD to background microbiota was calculated by dividing the mean cfu of the LOD to the mean cfu of the un-inoculated pork meat.…”
