Staphylococcus aureus is an important foodborne pathogen and can produce a wide range enterotoxins, which contribute to food poisoning. The aim of this study was to interrogate foodborne strains of S. aureus for phenotypic and genotypic characteristics. Strains were screened for enterotoxins, hemolysins and antimicrobial resistance, and the genetic(More)
OBJECTIVES The objective of this study was to investigate the silver gull as an indicator of environmental contamination by salmonellae and carbapenemase-producing Enterobacteriaceae (CPE) in south-east Australia. METHODS A total of 504 cloacal samples were collected from gull chicks at three nesting colonies in New South Wales, Australia [White Bay (n =(More)
Staphylococcus aureus is a major food-borne pathogen due to the production of enterotoxin and is particularly prevalent in contaminated milk and dairy products. The lactic acid bacteria (LAB) are widely used as biocontrol agents in fermented foods which can inhibit pathogenic flora. In our work, we investigated the influence of three strains of LAB(More)
The study objective was to investigate whether the strain of L. monocytogenes serotype 1/2c isolated from neonatal listeriosis carries a premature stop codon (PMSC) mutation in the inlA gene. The strain was characterized by serotyping, macrorestriction analysis after digestion with the restriction enzyme AscI, and sequencing of the inlA gene. The tested(More)
A cluster of 14 cases of Salmonella Urbana cases in Finland, the Czech Republic and Latvia were identified in January-February, 2010. The majority of cases (11) were male and children under 16 years of age. The investigation is currently ongoing and comparison of pulsed-field gel electrophoresis (PFGE) profiles of the isolates suggests that the cases may(More)
Update: Multinational listeriosis outbreak due to 'Quargel', a sour milk curd cheese, caused by two different L. monocytogenes serotype 1/2a strains, 2009-2010 We previously reported an outbreak of listerio-sis in Austria and Germany due to consumption of 'Quargel' cheese. It comprised 14 cases (including five fatalities) infected by a serotype 1/2a(More)
