Two-component anti-Staphylococcus aureus lantibiotic activity produced by Staphylococcus aureaus C55

Article Abstract:

A study was conducted to analyze the nature of the bactericidal activity of Staphylococcus aureus C55 and to show the production of three antibacterial peptides responsible for the production of inhibitory activity of S. aureaus C55. Sodium dodecyl sulfate-polyacrylamide gel electrophoresis was carried out using high performance liquid chromatography-purified preparations of staphylococcins C55-alpha and C55-beta. Results showed that two of the three peptides were lantibiotic molecules that acted synergistically to kill strains of S. aureus but not S. epidermidis.

Staphylococcus aureus and staphylococcal enterotoxin A in breaded chicken products: Detection and behavior during the cooking process

Article Abstract:

The presence of Staphylococcus aureus and staphylococcal enterotoxin A (SEA) in 20 industrial breaded chicken products obtained from different retail butchers and supermarket stores in Italy is examined. The levels of contamination in the products analyzed are found to be quite low, although the pH values and water activities in the samples considered are in ranges favorable for S. aurens GROwth

High prevalence of Vibrio cholerae non-01 carrying heat-stable-enterotoxin-encoding genes among Vibrio isolates from a temperate-climate river basin of Central Italy

Article Abstract:

The high prevalence of Vibrio chlorae non-O1 carrying heat-stable-enterotoxin-encoding gene among Vibrio isolates from temperate-climate river basin of Central Italy was investigated. The study isolated vibrios from 70% of water samples. Results indicate that considerable circulation of sto-positive vibrios occur in environments with temperate-climate freshwater.
