Catheter-associated urinary tract infections account for 40% of all nosocomial infections and are the most common source of gram-negative bacteremia in hospitalized patients. Therapy and Prevention A.
Coagulase negative Staphylococci as causative agents of urinary tract infections-prevalence and resistance status in IGIMS, Patna. Staphylococcus saprophyticus showed the highest sensitivities to all the antimicrobials whereas Staphylococcus haemolyticus had the highest resistance rates. 66.6% of staphylococcus epidermidis and 60%

Theundoubted role ofcatalase-positive, coagulase-negative Gram-positive cocci, Staphylococcus epi-dermidis, and Micrococcus species in causing urinary tract infection has gradually become accepted in recent years. These organisms did not appear to occur commonlyin ourroutine practice, though other workers have reported an incidence

Overview. Coagulase-negative staphylococci (CoNS) are a type of staph bacteria that commonly live on a person’s skin. Doctors typically consider CoNS bacteria harmless when it remains outside the body. However, the bacteria can cause infections when present in large amounts, or …
Coagulase-negative staphylococci (CoNS) are part of the normal flora of human skin . These organisms have relatively low virulence but are increasingly recognized as agents of clinically significant infection of the bloodstream and other sites.
Epidemiological studies of Coagulase-negative staphylococcus infection is complicated by the fact that this organism is a normal commensal on the skin, and differentiating infection from colonization and contamination may be difficult.
Pathogen Name and Classification
Coagulase negative staphylococci (CoNS) species such as Staphylococcus epidermidis and Staphylococcus hemolyticus are commonly found on the skin and the mucous membranes of many individuals. CoNS is a common contaminant of the artificial valves, joints, pacemakers and central nervous system shunts and can cause blood, heart, brain, bone and eye infections.
Staphylococcus saprophyticus. Staphylococcus saprophyticus is a Gram-positive coccus belonging to the coagulase-negative genus Staphylococcus. S. saprophyticus is a common cause of community-acquired urinary tract infections.
They are important pathogens in individuals with structural abnormalities of the urinary tract and in individuals with urinary tracts that have been instrumented. Staphylococcus saprophyticus, a Gram positive coagulase negative staphylococcus, causes about 10% of infections …
