Staphylococci are:

• gram-negative diplococci

• gram-positive diplococci

• gram-positive cocci in the form of a bunch of grapes

• gram-negative rods

• gram-positive rods

Characteristic signs of staphylococci:

• gram-negative cocci

• gram-positive cocci

• motionless bacteria

• strict anaerobes

• facultative anaerobes

The signs common to staphylococci and streptococci include:

• don’t spore formation

• the presence of cytochromes

• catalase activity

• spherical shape of cells

• positive Gram stain.

The following symptoms are characteristic of S. saprophyticus:

• the presence of a DNA enzyme

• ability to break down sucrose

• the presence of plasmocoagulase

• the presence of phosphatase

• ability to hemolysis

The main component of the cell wall of staphylococci is:

• mycolic acids

• peptidoglycan

• lipids

• lipopolysaccharide

• chitin

The elective medium for staphylococci is:

• Ploskoreva culture medium
