Coagulase-positive Staphylococci ATCC 25923, a known coagulase producer was included as a control strain. Results: 94 out of 156 pus swabs were coagulase positive. This implied that the prevalence of Coagulase-positive staphylococci was 94(60.3%) among Diabetic patients with foot ulcers seeking treatment at Vihiga County Referral Hospital, Kenya. The ability to clot blood by producing coagulase distinguishes the virulent pathogen, Staphylococcus aureus, from the less virulent coagulase-negative staphylococcal species. Coagulase-positive S. aureus is among the most ubiquitous and dangerous human pathogens, for both its virulence and its ability to develop antibiotic resistance.
Coagulase-negative staphylococci comprised over 75% of microorganisms isolated from positive blood cultures in the neonates examined in our study, which corroborates with that of multiple studies which have shown that 50–66% of isolates from bacteremic neonates’ blood cultures were CoNS [25–28].

Other coagulase positive staphylococcus constituted 67.4% of the isolates. Staphylococcus aureus Staphylococcus aureus is a bacterium that causes staphylococcal food poisoning, a form of gastroenteritis with rapid onset of symptoms. S. aureus is commonly found in the environment (soil, water and air) and is also found in the nose and on the skin of humans. Description of the organism Staphylococcus aureus is a facultative anaerobic Gram-positive coccus, which is non-motile, and catalase and coagulase positive. Some S. aureus strains are able to produce staphylococcal enterotoxins (SEs) and are the causative agents of staphylococcal food poisoning. Staphylococci exist in air, dust, sewage, water, milk, and food, as well as on food equipment, environmental surfaces, humans, and animals. The coagulase test is one way to differentiate the highly pathogenic S. aureus from the other less pathogenic staphylococcal species on the human body.

staphylococci, Staphylococcus aureus is one of the major human pathogens in which it is responsible for toxic shocks, food borne diseases and especially a wide spectrum of suppurative infections [2]. The laboratory of medical biology plays a very important role in the diagnosis of infections, especially bacterial infections.

Diagnosis of staph infections begins with attempting to culture the bacteria from an infected site. Any area with pus, crusty drainage, or blisters should be cultured. Blood from patients with sepsis, toxic shock syndrome, or pneumonia should be cultured. Standard microbiological techniques include a positive coagulase test to identify staph. S.
