Clostridium botulinum
Can be isolated from home-canned green beans. Obligate anaerobic growth on blood agar, Gram positive rods with subterminal endospores.
Neisseria gonorrhoeae
A 21-year old male patient complaining of dysuria with a purulent discharge. The isolate produced small round gray colonies on chocolate agar with no growth on blood. The isolate is a gram negative cocci, oxidase positive.
Penicillium notatum
Growht on Sabourauds Dextrose agar at 25C. Identification of characteristic Conidia spores which resemble a chickens foot or a paint brush appearance.
Mycobacterium tuberculosis
Acid fast bacilllus, growth on Lowenstein-Jenson agar in 6 weeks.
Leptospira interrogans
Will enter cuts and abrasions throughout the feet and/or associated with outbreaks upon exposure to contaminated water with the urine of infected animals. Patient will experience fever, headache, chilles, muscle aches, and Jaundice. The organism will not grown on Blood or Chocolate agar and must be identified serologically.
Escherichia coli
Causing up to 80% if nist ascending UTIs. Growth on Blood agar and MacConkeys agar with small round colonies that ferment lactose, Oxidase negative.
Pseudomonas aeruginosa
Growth on Blood Agar and MacConkey agar, non-lactose fermenting colonies, oxidase positive. Responsible for respiratory infections involving cystic fibrosis patients, third degree burn victoms and swimmers ear.
Treponema Pallidum
Slender coiled organisms demonstrated by dark-field examination of material from the primary lesion of the disease found on or near the genitals.
Neisseria meningitides
Isolated from a cerebral spinal fluid. Gram stain evidence of gram negative intracellular diplococci, growth on chocolate agar and no growth on Blood. Oxidase positive.
Escherichia coli 0157:H7
Associated with a hemorrhagic colitis originating from teh consumption of uncooked ground beef and other foods contaminated with livestock waste.
Bacteroides fragilis
Most common anaerobic infection. Associated with teh female genital tract and intraabdominal infections.
Borrelia burgdorferii
Progressive stages of this disease resultes in inflammation of the weight bearing joints and possible neurological complications. The microorganism can not be cultured on Blood and Chocolate agar and is transmitted via trick vector.
Epstein-Barr virus

Punture wounds, drug injections, and infected umbilical stumps are portals of entry for this toxigenic disease that results in a general rigidity of the body with muscle spasms occuring throughout. Terminal endospores.
