15: bacteriophages: the streptococcus organisms are susceptible to bacteriophages. The staphylococcus organisms are not susceptible to the bacteriophages. 16: toxin: they cannot produce the toxins but they can cause severe infections.
Hemolytic activity on rabbit blood agar, 42 per cent liquefied gelatin, and 30 per cent fermented mannitol. All of the coagulase positive strains grew confluently (4+) on 25 per cent human serum agar, whereas 6 of the coagulase negative strains showed 2+ growth and 22 gave 1+ growthunderthe sameconditions.

Haemolysis as the sole criterion of the pathogenicity of staphylococci detected on bacteriological examination of slaughtered animals should be reconsidered.
Aureus, the most common cause of staph infections, is frequently hemolytic on blood agar. Because the feeding process of the plasmodium parasites damages red blood cells, malaria is sometimes called parasitic hemolysis in medical literature.

Staphylococcus is usually either beta hemolytic or not hemolytic at all (called gamma hemolysis). Pathogenic staphylococci can produce a variety of virulence factors, including toxins,coagulase, leucocidins, and hydrolytic enzymes that can damage host tissues.
Studies of the two strains of staphylococci demonstrated that the yellow staphylococcus was innocuous when grown in milk, but that milk inoculated with the white strain produced typical symptoms when consumed by human volunteers.

Studies in the 1980s found high mics of teicoplanin, sometimes within the resistance range, among methicillin-resistant staphylococcus haemolyticus. Overall, mics of teicoplanin against coagulase-negative staphylococci show a wide range, occasionally higher than the clsi resistance breakpoint (mic ≥32 µg/ml).
