Commercial biological indicator spore strips in glassine envelopes, produced by three manufacturers, were evaluated by fraction-negative procedures after being heated at 121.0 +/- 0.05 degrees C. Only one type of spore strip met the manufacturer's specifications. The strips of one manufacturer were further evaluated by fraction-negative and survivor curve-plate count procedures after being heat...

The search for novel antimicrobial compounds from the environment has been gaining momentum with increase in resistance of pathogens. In present study, potential 11 local isolates Actinobacteria which were isolated rhizosphere soils three endemic plants Turkey was evaluated against different pathogenic bacteria and Candida albicans. Antimicrobial activity investigated by disk diffusion agar met...

The recovery of bacteria and fungi from blood cultures was compared in conventional tryptic soy broth (TSB) bottles and in TSB bottles with an agarcoated slide attachment. A total of 2,662 sets of blood cultures, including 413 that were positive (15.5%), were evaluated. Significantly more gram-positive and gram-negative bacteria were recovered in the slide culture bottles than in conventional b...

This study assessed biofilm formation on polystyrene by Staphylococcus aureus, Listeria monocytogenes, L. welshimeri and Escherichia coli, isolated from a slaughtering plant, grown on tryptic soy broth (TSB) using different glucose concentrations. The tested bacteria produced biofilm in at least one of the concentrations used, and some of them were strong biofilm producers.

The motility characteristics of natural assemblages of coastal marine bacteria were examined. Initially, less than 10% of the bacteria were motile. A single addition of tryptic soy broth caused an increase in the motile fraction of cells but only after 7 to 12 h. Motility peaked at 15 to 30 h, when more than 80% of cells were motile. These results support the proposal that energy limits motilit...

Aim: The study was conducted to evaluate the performance of different enrichment broths such as Tryptic Soy Yeast extract Broth (TSBYE), Brain Heart Infusion broth (BHI), Nutrient Broth (NB), Luria Broth (LB) and Peptone water (PW) for the detection of Listeria monocytogenes, Yersinia enterocolitica, Staphylococcus aureus and Salmonella enterica Typhimurium. Materials and Methods: The bacterial...
