“…Although Y. entrocolitica has been known as a most principal cause of human infections, however there are some reports about coursing gastroenteritis in human by other species such as Y. intermedia, Y. kristensen and Y. frederiksenii (Brenner and Bercovier, 1980;Hamama and Marrakchi, 1992). Strains of these pathogenic biotypes contain marker associated with virulence and these are located on the chromosome (ail) and on the virulence plasmid (PYV) (Goverde et al, 1993;Khorramizadeh et al, 2007).…”

The objective of this study is to investigate the prevalence and determine the antimicrobial susceptibility pattern of Yersinia species in beef meat and chicken meat samples in different seasons. The most antibiotic resistance belongs to cephalothine (98%). Our results showed that isolation ratio of Y. enterocolitica and the other species is higher in cold climates. The majority of isolates were resistant to cephalothine. The most active pharmacologic agents were chloramphenicol, gentamicin and trimetoprim.

“…This could have been due to an underestimation of the viable cell count on cheese. CIN medium, however, is the most efficient medium for enumeration of Y. enterocolitica (8,21,22), and it appears unlikely that this approach should underestimate the cell count by a factor of 20. The difference could also be due to a repression of the promoter by BHI agar.…”

Bioluminescent mutants of Yersinia enterocolitica were generated by transposon mutagenesis using a promoterless, complete lux operon (luxCDABE) derived from Photorhabdus luminescens, and their production of light in the cheese environment was monitored. Mutant B94, which had the lux cassette inserted into an open reading frame of unknown function was used for direct monitoring of Y. enterocolitica cells on cheeses stored at 10°C by quantifying bioluminescence using a photon-counting, intensified charge-coupled device camera. The detection limit on cheese was 200 CFU/cm 2 . Bioluminescence of the reporter mutant was significantly regulated by its environment (NaCl, temperature, and cheese), as well as by growth phase, via the promoter the lux operon had acquired upon transposition. At low temperatures, mutant B94 did not exhibit the oftenreported decrease of photon emission in older cells. It was not necessary to include either antibiotics or aldehyde in the food matrix in order to gain quantitative, reproducible bioluminescence data. As far as we know, this is the first time a pathogen has been monitored in situ, in real time, in a "real-product" status, and at a low temperature.
