For the detection of Staphylococcus aureus food poisoning which can lead to staphylococcal enteritis a stool culture may be required. A stool culture is used to detect the presence of disease-causing bacteria (pathogenic) and help diagnose an infection of the digestive tract. In the case of staphylococcal enteritis, it is conducted to see if ...
Staphylococcus aureus is a gram-positive spherically shaped bacterium, a member of the Bacillota, and is a usual member of the microbiota of the body, frequently found in the upper respiratory tract and on the skin. It is often positive for catalase and nitrate reduction and is a facultative anaerobe, meaning that it can grow without oxygen. [1]
The yields of Salmonella from stool samples obtained, when using this medium, are higher than those obtained with LEIFSON agar or Salmonella–Shigella agar. Phenylethyl alcohol agar selects for Staphylococcus species while inhibiting Gram-negative bacilli (e.g., Escherichia coli, Shigella, Proteus, etc.).
A stool test is a medical diagnostic technique that involves the collection and analysis of fecal matter. Microbial analysis (culturing), microscopy and chemical ...
The IMViC tests are a group of individual tests used in microbiology lab testing to identify an organism in the coliform group.A coliform is a gram negative, aerobic, or facultative anaerobic rod, which produces gas from lactose within 48 hours.
MacConkey agar is a selective and differential culture medium for bacteria. It is designed to selectively isolate gram-negative and enteric (normally found in the intestinal tract) bacteria and differentiate them based on lactose fermentation . [ 1 ]

Staphylococcus species are facultative anaerobes (capable of growth both aerobically and anaerobically). [15] All species grow in the presence of bile salts. All strains of Staphylococcus aureus were once thought to be coagulase-positive, but this has since been disproven. [16] [17] [18] Growth can also occur in a 6.5% NaCl solution. [15]
