A Study of Slime-Positive Coagulase-Negative Staphylococci
Coagulase-negative staphylococci (CNS) have been involved in medical device and catheter-associated sepsis. Extracellular slime produced by CNS has been implicated as an important factor of pathogenicity. The current investigation involved perfection of a technique for separating slime from the …

Phenotypic and molecular characterization of coagulase negative staphylococci from pigs and humans in Lusaka province, Zambia.
Coagulase-negative staphylococci (CoNS) are normal inhabitants of human and animal skin as well as mucous membranes, yet they have emerged as significant pathogens in healthcare settings, causing serious infections. Initially described as avirulent in 1884, CoNS, particularly Staphylococcus …

Assessment of Antimicrobial Resistance in Pathogens Responsible for Causing Bovine Mastitis in Kentucky
… which was identified in 13% of milk samples. Coagulase negative Staphylococci (11%) and streptococci species (10%) were also found to be major causes of mastitis in Kentucky. Only one isolate of <em>Streptococcus agalactiae</em> was identified, indicating that this species is not prevalent in …

Gram-positive infections in patients with end-stage renal disease
Gram-positive microorganisms, specifically coagulase-negative staphylococci are the most common species recovered from clinical culture specimens of patients with end-stage renal disease. The propensity of coagulase-negative staphylococci (CNS) to cause infection in this patient group has been …
