catalase positive species to identify the coagulase positive Staphylococcus aureus. Coagulase is a virulence factor of S. aureus. The formation of clot around an infection caused by this bacteria likely protects it from phagocytosis. This test differentiates Staphylococcus aureus from other coagulase ...
The Enterobacteriaceae are Gram-negative rod-shaped bacteria, which are typically motile by virtue of peritrichous flagella and are non-sporing, facultative anaerobes, which will grow in the presence of bile salts. They are oxidase negative, catalase positive, reduce nitrate, and, almost all, ...
Figure 4. (a) In this gram-stained specimen, the violet rod-shaped cells forming chains are the gram-positive bacteriaBacillus cereus. The small, pink cells are the gram-negative bacteriaEscherichia coli. (b) In this culture, white colonies ofB. cereushave been grown on sheep blood agar. (...

This enzyme is important in the electron transport chain portion of aerobic respiration in bacteria. When a bacteria can produce cytochrome c oxidase, it is said to be oxidase-positive, and when bacteria cannot produce the enzyme, they are oxidase-negative. P. luteola is oxidase-negative. ...
While infections by Gram-positive bacteria, especially methicillin-resistant Staphylococcus aureus, have been the focus of attention for scientists, governments and the media, Gram-negative infections have not been given so much consideration over the last couple of decades. Progress in f...

Long, thin, slowly growing, oxidase-positive, catalase-positive gram-negative rods that do not grow on MacConkey agar should suggest DF-2. Although testing of antimicrobial susceptibility is problematic, DF-2 has been found to be resistant to aminoglycosides. The drug of choice is penicillin. ...

Like Gram-positive bacteria, Gram-negative organisms can be cocci or rods. Most Gram-negative bacteria are rods, but a few important species are in cocci form.Neisseriaspecies are Gram-negative cocci that typically attach in pairs and are some of the most common aerobic Gram-negative cocci.Neis...
