"Human Pathology"

Lancefield group A, beta hemolysis. Sensitive to bacitracin. Causes strep throat, rheumatic fever, and scarlet fever.

Isolated from soil. Forms red pigment (best on high carbohydrate medium) and has oval eccentric spores. 

This organism is a common inhabitant of intestinal flora, and can be a major cause of urinary tract infection.

A Common Intestinal Flora Isolate, Demonstrates Alpha Hemolysis on Blood Agar Growth Medium

Penicillium notatum is a deuteromycete that produces penicillin. It is available in normal and high-yield strains.

This spore-forming, thermophilic organism is commonly used for germicidal and sporicidal testing due to its ability to withstand higher-than-normal temperatures.

No Lancefield group shown, alpha hemolysis. Bile solubility test positive, optochin sensitive. Causes pneumonia. 

Both of these strains of Serratia marcescens are colorless mutants when plated alone, but when grown together, they produce a red pigment.

This organism is commonly isolated from soil, and depending upon the temperature of its environment, can produce a distinctive red pigment.

Hemolysis, the rupture of red blood cells, is induced by certain species of streptococcal bacteria that produce extracellular hemolysin.  Observe this phenomenon with this set of 3 non-pathogenic species

This organism is occasionally isolated from soil, but most frequently from smegma- a secretion from male and female genitalia.

This organism is normal flora of human intestine and may be pathogenic in humans. This organism will grow in Sodium chloride solution.

Normal flora of respiratory tract. Beta-lactamase positive. Also known by the name Branhamella catarrhalis

This organism can be isolated from many human urinary tract infections, as well as polluted water and sewage. It is commonly identified by its distinctive grape-like smell (trimethylamine) or because it can turn the agar light green due to production of a blue pigment (pyocyanin).
