are all staph aureus coagulase positive?
432560
S aureus and S intermedius are coagulase positive. All other staphylococci are coagulase negative. They are salt tolerant and often hemolytic. Identification requires biotype analysis.
434868
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.

People and animals can carry MRSA without any signs of infection at all. This is known as colonization, which may be short-term or long-term. Infection with MRSA causes signs of inflammation (e.g. heat, pain, swelling, discharge, fever). Pets such as dogs and cats do not commonly carry MRSA.

Among people who are in the secondary (middle) stage of infection, the RPR test result is nearly always positive. The RPR test also can produce false-positive results, suggesting you have syphilis when you actually don't.

More evidence is currently emerging to show that Staphylococcus, particularly Staphylococcus aureus, can colonize the reproductive systems and affect their structure and function. Staphylococcal infection has become one of the most common causes of infertility in both males and females.

Methicillin-resistant Staphylococcus aureus (MRSA) is a bacterium that causes infections in different parts of the body. It's tougher to treat than most strains of staphylococcus aureus -- or staph -- because it's resistant to some commonly used antibiotics.
482440
There are two types of MRSA infections: community-acquired (CA) and hospital-acquired (HA). The most common type is HA-MRSA, but CA-MRSA is becoming more common.
537339
This type of staph is called MRSA (Methicillin-Resistant Staphylococcus Aureus). Anyone can get MRSA. Infections range from mild to very serious, even life- threatening. MRSA is contagious and can be spread to other people through skin-to- skin contact.

Learn which cocci are Gram negative; 3. Learn all the Gram positive rod names (all the rest are Gram negative rods). LEARN THE COCCI; Most human bacteria pathogens are rods. ... Gram positive cocci always have coccus in their name; Enterococcus, Peptostreptococcus, Staphylococcus and Streptococcus.

Moreover, PDW and MPV levels in severe sepsis patients were higher than in patients with sepsis. It has been demonstrated that coagulation and platelet activation/hyper aggregation can occur in an early phase of sepsis.

The emergence of Panton-Valentine leukocidin (PVL)-positive methicillin-resistant Staphylococcus aureus (MRSA) is a public health concern worldwide. PVL is associated with community-associated MRSA and is linked to skin and soft tissue infections (SSTIs).

Both types of MRSA are seen in chronic wounds. MRSA has become a huge worldwide health threat and an update on its current impact on wounds is warranted. The specific characteristics of HA-MRSA and CA-MRSA are presented, as well as, the impact these organisms have on acute and chronic wounds.

The antibiotic sensitivity rates of all the staphylococcal species for linezolid, rifampin, and trimethoprim/sulfamethoxazole (TMP/SMX) were excellent (100.0%, 93%, and 91.7%, respectively), but those for ciprofloxacin, clindamycin, and fusidic acid were only fair (69.7%, 67.6%, and 58.7%, respectively) (Table 2).

Staphylococcus species are catalase positive and facultatively anaerobic, except for S. aureus subsp. anaerobius and S. saccharolyticus, which are catalase negative and anaerobic.

Learn all the Gram positive rod names (all the rest are Gram negative rods). LEARN THE COCCI; Most human bacteria pathogens are rods. If you learn the cocci all the other stainables are rods. Gram positive cocci always have coccus in their name; Enterococcus, Peptostreptococcus, Staphylococcus and Streptococcus.

Staphylococcus epidermidis is a Gram-positive bacterium, and one of over 40 species belonging to the genus Staphylococcus. It is part of the normal human flora, typically the skin flora, and less commonly the mucosal flora. It is a facultative anaerobic bacteria.
