Bacteria in the genus Staphylococcus are pathogens of man and other mammals. Traditionally they were divided into two groups on the basis of their ability to clot blood plasma (the coagulase reaction). The coagulase-positive staphylococci constitute the most pathogenic species S aureus.
1 Δεκ 2021 · Staphylococcus aureus is a commensal bacterium known to colonize the skin, nares, and gastrointestinal tract of humans. Asymptomatic workers can contaminate food via manual contact or through respiratory secretions thus becoming the source of staphylococcal food poisoning.
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).
Members of the genus Staphylococcus still represent a topic of great relevance due to the numerous types of infections they cause in humans and animals. Staphylococci have emerged as important pathogens for both nosocomial and community-acquired infections in people.
4 ημέρες πριν · The term staphylococcus, generally used for all the species, refers to the cells’ habit of aggregating in grapelike clusters. Staphylococci are microbiologically characterized as gram-positive (in young cultures), non-spore-forming, nonmotile, facultative anaerobes (not requiring oxygen).
Table 1 shows examples illustrating linkage and transmission of Salmonella, E. coli, and Enterococcus spp. clones from the food chain to humans. It includes studies developed in diverse time frames that established such linkages.
Key Points. Staphylococci are gram-positive aerobic organisms. Staphylococcus aureus is the most pathogenic; it typically causes skin infections and sometimes pneumonia, endocarditis, and osteomyelitis. It commonly leads to abscess formation.
