Staphylococcus aureus

I. Organism Information

A. Taxonomy Information

1. Species

a. Staphylococcus aureus

i. Taxonomy ID: 1280

ii. Description:

Staphylococcus aureus is a Gram-positive pathogen that causes a wide range of diseases, and is becoming increasingly resistant to antibiotics (1). These resistant bacteria are called methicillin-resistant Staphylococcus aureus, or MRSA. S. aureus is responsible for a variety of ailments, including carbuncles, food poisoning, wound and medical device-related infections, bacteremia, necrotizing pneumonia, and endocarditis (2). S. aureus forms a fairly large yellow colony on rich medium and is hemolytic on blood agar. Staphylococci are facultative anaerobes that ferment glucose to lactate. The bacteria are catalase-positive and oxidase-negative. S. aureus can grow at a temperature range of 15 to 45 degrees and at NaCl concentrations as high as 15 percent. Almost all strains of S. aureus produce the enzyme coagulase. S. aureus should always be considered a potential pathogen (3).

a. Shape:

Cocci 0.5-1.0 μm in diameter. Cells occur singly or in pairs. Division is in two planes, giving rise to clusters. Colonies are smooth, raised, glistening, circular, entire and translucent. Single colonies may obtain a size of 6-8 mm in diameter (4).
