Columbia Blood Agar with Horse Blood/Columbia CAP Agar Biplate

Cultivate, isolate and identify a broad range of microorganisms (staphylococci and streptococci) with clearly visible hemolytic reactions while simultaneously detecting and isolating staphylococci and streptococci with Thermo Scientific™ Oxoid™ Columbia Blood Agar with Horse Blood/Columbia CAP Agar Biplate. The convenient biplate format allows simultaneous detection of Gram-negative and Gram-positive organisms allowing faster diagnostic decision making.

Produce more diagnostic details of pathogenic organisms while reducing storage capacity issue in the incubator with a bi-plate that allows simultaneous isolation and detection of staphylococci and streptococci.

• The addition of colistin in Columbia CAP Agar inhibits the growth of a large portion of Gram-negative accompanying flora without changing the colony morphology.
• Space-saving bi-plate format
• Ready-to-use convenience of prepared media

Staphylococcus aureus is a coagulase-positive, catalase positive, gram-positive cocci that occurs singly or in pairs, tetrads, short chains, and grape-like clusters. It is commonly carried on the skin and in the nose of healthy individuals but is also a major cause of infection in both healthcare and community settings worldwide. S. aureus can produce a variety of syndromes with clinical manifestations, including skin and soft tissue infections, empyema, bloodstream infections, pneumonia, osteomyelitis, septic arthritis, endocarditis, sepsis, and meningitis.

Streptococci are facultatively anaerobic, catalase-negative, gram-positive cocci that occur as pairs or chains. They cause a wide variety of clinical diseases including pharyngitis, scarlet fever, otitis media, impetigo, meningitis, neonatal sepsis, pneumonia, endocarditis, osteomyelitis, and necrotizing fasciitis. One of the most useful phenotypic characteristics of streptococci is the hemolytic reaction, generally classified as alpha, beta, or gamma according to the appearance of zones around colonies growing on Blood Agar. Beta-hemolytic streptococci are further characterized by Lancefield groups based on the antigenic differences in group-specific polysaccharides located in the bacterial cell wall.
