The Effect of Intrapartum Vancomycin on Vaginal Group B Streptococcus Colony Counts.

Objective: To define the temporal relationship between intrapartum intravenous vancomycin administration and vaginal group B streptococcus (GBS) colony counts.

Study Design: Prospective cohort study conducted from October 2014 to February 2017. Women with antenatal cultures demonstrating GBS colonization and a plan for vancomycin administration were eligible.

Association of psychrotrophic Clostridium spp. with deep tissue spoilage of chilled vacuum-packed lamb.

Early spoilage of commercial vacuum-packed chilled lamb legs was manifested as an objectionable 'cheesy', deep tissue odour that became evident when a cut was made into the stifle joint. Investigation of the probable causative agents led to the isolation of two psychrotrophic strains of clostridia. The isolates could not be identified using traditional identification schemes.

Psychrotrophic Clostridium spp. associated with 'blown pack' spoilage of chilled vacuum-packed red meats and dog rolls in gas-impermeable plastic casings.

'Blown pack' spoilage of vacuum-packed chilled beef, lamb and venison, and of a cooked meat product, chilled dog rolls packed in an oxygen-impermeable plastic casing, was characterised by sensory, chemical and microbiological analysis. Investigation of the probable causative agents led to the isolation of eight strains of psychrotrophic clostridia. Three strains have been provisionally identified as C.

Incidence and coincidence of Listeria spp., motile aeromonads and Yersinia enterocolitica on ready-to-eat fleshfoods.

A survey for the presence of Listeria spp., Yersinia enterocolitica and motile aeromonads in 203 samples of ready-to-eat fleshfoods purchased from retail outlets was conducted. Overall, 39.

Growth of Escherichia coli and Salmonella typhimurium on high-pH beef packed under vacuum or carbon dioxide.

A strain each of Escherichia coli and Salmonella typhimurium, were inoculated onto samples of high-pH (greater than 6.0) beef. Samples were packaged under vacuum or CO2 and stored at 8, 10, 12, 15, 20 or 30 degrees C.
