Development of a new antimicrobial concept for boar semen preservation based on bacteriocins.

The conventional storage temperature of 16-18 °C provides optimal conditions for the preservation of boar sperm quality, which are extremely cold sensitive cells. On the other hand, however, it requires the addition of antibiotics to inhibit bacterial growth. Rising numbers of antibiotic resistant bacteria call for alternatives to this conventional storing method.

Prevalence and quantitative analysis of ESBL and AmpC beta-lactamase producing Enterobacteriaceae in broiler chicken during slaughter in Germany.

Food producing animals are considered a reservoir for Extended-spectrum beta-lactamase (ESBL) and AmpC beta-lactamase (AmpC) producing Enterobacteriaceae. Therefore, meat is discussed to be a potential source for the transmission of these resistant bacteria to humans. There is only limited information about the quantitative load of ESBL-/AmpC-producing Enterobacteriaceae in different sample matrices during slaughter and their distribution in the slaughterhouse environment.

Development of transient phage resistance in Campylobacter coli against the group II phage CP84.

Recently, there is a growing interest in the use of bacteriophages for pre- and post-harvest applications to reduce foodborne pathogens (including Campylobacter) along the food chain. Quantitative Campylobacter reductions of up to three log10 units have been achieved by phage application. However, possible phage resistance might limit this approach.

Control of Campylobacter spp. and Yersinia enterocolitica by virulent bacteriophages.

The efficacy of the Campylobacter (C.) phages NCTC12684 (group II) and CP81 (group III) and of the Yersinia (Y.) phage PY100 to reduce the numbers of Campylobacter and Y.
