Phenotypic and molecular typing of Salmonella strains reveals different contamination sources in two commercial pig slaughterhouses
Article Abstract:
The origin of Salmonella contamination on swine carcasses and the distribution of Salmonella serotypes in two commercial slaughterhouses during normal activity are determined by using pulsed-field gel electrophoresis (PFGE) and phage typing. The antibiotic resistance profiles (ARPs) for six antibiotics are determined as well in order to monitor the spread of multidrug-resistant strains in the feces of the pigs, on the carcasses, and in the slaughterhouse environment.

Differential inlA and inlB expression and interaction with human intestinal and liver cells by Listeria monocytogenes strains of different origins
Article Abstract:
A number of Listeria monocytogenes strains of different origins are evaluated for invitro invasion capacity for various human cell types and for expression levels of specific virulence genes. The findings reveal that the observation led to study the mRNA expression levels of inlA, inlB, and ami, important virulence genes mediating adhesion and eukaryotic cells, by real-time reverse transcription-PCR for 27 clinical and 37 nonclinical Listeria monocytogenes strains.

Incidence and diversity of potentially highly heat-resistant spores isolated at dairy farms
Article Abstract:
The Belgian diary farms are studied in order to understand the presence, sources, and nature of potentially highly heat-resistant spores in raw milk in general and the presence of Bacillus sporothermodurans spores in particular. Assessment and characterization of these spores are very important to allow the dairy or food industry to deal with newly arising microbiological problems.
