Identification of pathogens

School of fish/railroad track describes what pathogen

H ducreyi

Gram positive lancet shaped diplococci with alpha hemolysis describe what pathogen

Strep pneumoniae

Gram negative diplococci with capsule which ferments maltose describes what pathogen

N. meningitidis

Gram negative diplococci +- capsule which ferments glucose

N. gonorrhoeae

Gram positive rods, box car shape, double zone hemolysis describe what pathogen

Clostridium perfringens

Swarming hypermotile on blood agar describes what pathogen

Proteus spp

How do you diff P mirabilis from P vulgaris

Vulgaris makes indole, mirabilis does not

Bluish green agar with metallic sheen and grape like smell describes what pathgoen

P. aeruginosa

Gram negative bacilli, growing pink colonies on MacConkey agar and positive string test describes what pathogen

K. pneumoniae

Gram negative bacilli with red pigmentation when grown at 20-30C from prodigiosin describes what pathogen

S marcenscens

Clue cells is specific for what pathogen

G. vaginalis

Gram neg bacilli with gull wing characteristic describes what pathogen

Campylobacter jejuni

Gram positive bacilli with bamboo wall appearance describes what pathogen

B. anthracis

Chinese character/L shaped describes what pathogen

C. diphtheriae

Gram negative diplococci with hockey puck sign (entire colony moves when you try to pick it up) describes what pathogen

Moraxella catarrhalis

What is this

School of fish → H ducreyi

What is this

Lancet shape → S. pneumoniae

What is this if found in CSF

N. meningitidis

What is this if found in urine culture

N. gonorrhoeae

What is this

Boxcar shape → C perfringens

What is this

Hypermotility + swarming → Proteus spp

Swarming + hypermotile + indole production is what pathogen

S. mirabilis

What is this

Metallic sheen + bluish green color → P aeruginosa

What is this

Pink colony + mucoid string test → K. pneumoniae

Red pigmentation when grown at 20-30C is what pathogen

S. marcensens

What is this

Clue cell → G. vaginalis

What is this

Gull wing appearance → C. jejuni

What is this

Bamboo wall → B anthracis

What is this

Chinese character/L shaped → C. diphtheriae
