  Postgraduate Medicine: Coagulase-negative staphylococci
Furthermore, 60% to 80% of nosocomial coagulase-negative staphylococci are methicillin-resistant.
In general, isolation of the same strain of these staphylococci from multiple blood cultures implies that the organism is continuously present in the bloodstream and therefore may be regarded as a potential causative agent (2,8).
Coagulase-negative staphylococci of the S saprophyticus group, mainly S saprophyticus, which is the most common bacterium in the novobiocin-resistant group, are able to cause infectious diseases of the urinary tract of immunocompetent patients even in the absence of a foreign body.

 Staphylococci, staphylococci infection
Staphylococci are the most common form of bacteria found in dog skin disorders.
Staphylococci are gram-positive spherical bacteria cells (cocci), that typically occur in microscopic clusters similar to grapes (staphyle=bunch of grapes).
Indication of staphylococci infection is inflammation, raised temperature, swelling, and suppuration.

Staphylococci are common causes of infections associated with indwelling medical devices.
The association of S epidermidis (and to a lesser extent of other coagulase-negative staphylococci) with nosocomial infections associated with indwelling devices means that isolation of these bacteria from blood is likely to be important and not due to chance contamination, particularly if successive blood cultures are positive.
Staphylococci other than S aureus can cause infections in man. S epidermidis is the most important coagulase-negative staphylococcus (CNS) species and is the major cause of infections associated with prosthetic devices and catheters.

Coagulase-negative staphylococci infections can be controlled by routine postmilking teat dipping using a germicidal dip and antibiotic treatment of all quarters in all cows at drying off.
Dry cow therapy eliminates over 80% of coagulase-negative staphylococci infections; however, new coagulase-negative staphylococci infections can occur during the dry period since these organisms are part of the resident teat skin flora.

Jacobs and his colleague C. Good, MD, noted that their laboratory routinely reports all erythromycin-resistant staphylococci as being clindamycin-resistant.
Good noted that the clinical outcome of using clindamycin to treat inducibly clindamycin-resistant staphylococci is not clear: The few cases reported so far presented conflicting results.
What is clear is that a subset of erythromycin-resistant staphylococci exists that could be safely treated with clindamycin if adequate information were available.

Mannitol salt agar is a nutritive medium due to its content of peptones and beef extract, which supply essential growth factors, such as nitrogen, carbon, sulfur and trace nutrients.
The staphylococci which ferment mannitol will appear as colonies with a yellow zone, while those staphylococci which do not ferment mannitol will have a red or purple zone.
