Structure. Staphylococci are Gram-positive cocci about 0.5 – 1.0 μm in diameter. They grow in clusters, pairs and occasionally in short chains. The clusters arise because staphylococci divide in two planes. The configuration of the cocci helps to distinguish micrococci and staphylococci from streptococci, which usually grow in chains.
1 Δεκ 2021 · Food handlers carrying S. aureus in their nose can contaminate their hands and other parts of their body, acting as a major source of cross-contamination at any stage of the food production, processing and distribution chain (Colombari et al., 2007).
17 Ιουλ 2023 · Staphylococcus aureus is Gram-positive bacteria (stain purple by Gram stain) that are cocci-shaped and tend to be arranged in clusters that are described as “grape-like.” On media, these organisms can grow in up to 10% salt, and colonies are often golden or yellow (aureus means golden or yellow).
1 Ιουν 2018 · Abstract and Figures. Purpose of Review We present recent insights on S. aureus as a foodborne pathogen, thus providing readers with an update of current findings impacting prevention and control...
Moreover, we give an overview of out-break investigation approaches as well as food safety and food process criteria put in place to control S. aureus along the farm-to-fork food chain. We then question the role of methicillin-resistant S. aureus (MRSA) as foodborne pathogen.
1 Μαρ 2012 · Fifty-seven S. aureus isolates, previously obtained from different types of food, were screened by polymerase chain reaction with specific primers for the mecA gene, which mediates methicillin ...
9 Ιαν 2022 · Staphylococcal food-borne disease (SFD) is one of the most common food-borne diseases worldwide resulting from the contamination of food by preformed S. aureus enterotoxins.
