Students investigate the case of a family poisoned by household pesticides used to treat a bed bug problem.

This organism is often times isolated from food; in large amounts it can cause food poisoning

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

Isolated from sewage, human intestines, and urinary tract infections. Spreading colonies are seen on agar growth medium. 

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

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

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

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).
