17 Ιουλ 2023 · These organisms can grow aerobically or anaerobically (facultative) and at temperatures between 18 C and 40 C. Typical biochemical identification tests include catalase positive (all pathogenic Staphylococcus species), coagulase positive (to distinguish Staphylococcus aureus from other Staphylococcus species), novobiocin sensitive (to ...
15 Απρ 2024 · Interpreting results — Blood culture detection of Staphylococcus aureus should always be regarded as clinically significant, even if only a single positive blood culture bottle is observed . Identification of positive blood cultures should prompt initiation of empiric therapy as well as further clinical evaluation.
S. aureus also produces catalase; when applied to colony material, the catalase test is a rapid, useful test to distinguish staphylococci from other Gram-positive bacteria such as streptococci. S. aureus is a facultative anaerobe that grows by aerobic respiration or by fermentation, which yields principally lactic acid.
Other infections require samples of blood or infected fluids, which are sent to a laboratory to grow (culture), identify, and test the bacteria. Laboratory results confirm the diagnosis and determine which antibiotics can kill the staphylococci (called susceptibility testing).
Blood cultures may be positive for staphylococcal species, even when results from other cultures are negative. Obtain blood cultures from all patients with serious infections. Deck et al have...
It is a leading cause of bacteremia and infective endocarditis as well as osteoarticular, skin and soft tissue, pleuropulmonary, and device-related infections. This review comprehensively covers the epidemiology, pathophysiology, clinical manifestations, and management of each of these clinical entities.
Seventy percent of cultures were positive for S. aureus, 88% of which were positive for MRSA and 93% of which were PVL positive. Clinical cure rates at 7 days were similar and were >90% in the placebo arm.
