3 0 obj Methicillin-resistant Staphylococcus aureus (MRSA) is a cause of staph infection that is difficult to treat because of resistance to some antibiotics. The catalase enzyme, in particular, is considered to be involved in oxidative stress resistance, and catalase activity is an important criterion for differentiating staphylococci from streptococci. Classified as a form of staph infection, MRSA is resistant to most antibiotics and usually transmitted through direct contact with a dermal abrasion, such as a cut or scratch. Epidemiology and Outcome Determinants of Staphylococcus aureus Bacteremia Revisited: A Population-Based Study. Pleural involvement (48 percent) was more common than previously reported, and abscess formation (16 percent) occurred infrequently. The mode of transmission of S. aureus and different methods for its detection in different samples are defined. Conventional antibiotic options to treat this aggressive, multifaceted, and readily adaptable pathogen are becoming limited. Several neutrophiles are noted. Members of the Staphylococcus genus are gram-positive cocci and belong to the Micrococcus family. All it does it makes infections a little worse and cannot be controlled by some antibiotics.
