Family Enterobacteriaceae Gram Negative
Oxidase Negative
Bacillis shaped
Genus Campylobacter = Gram negative, oxidase positive
, Pathogenic Microbiology Exam

Helicobacter pylori has been implicated in almost 90% of gastric ulcers
all
Helicobacter pylori is speculated as being normal gastric flora
Hemophilus influenzae causes what three diseases? 1) Otitis media
2) Pneumonia
3) Meningitis - older children
It does NOT cause the flu!
How is Q fever spread? Unpasteurized milk
How is Rickettsia prowazekii spread? Lice
How is the Orienta species spread? Mites
How was Hemophilus aegyptius isolated as the causative It had a different plasmid profile
agent of the Brazilian hemorrhagic fever?
How would you distinguish Campylobacter jejuni from Oxidase Test
Salmonella enteritidis in a case history involving a food
infection with raw chicken? C. jejuni = O+
S. enteritidis = O-
If a virus contains an envelope, what is the basic method Alcohol
to control that virus?
Can inactivate the lipid membrane
In case histories dealing with hot tubs, saunas, or health Pseudomonas aeruginosa
clubs, what pathogen should immediately come to mind?
In case histories dealing with secondary infections of cystic Pseudomonas aeruginosa
fibrosis patients, what pathogen should immediately come
to mind?
In cases of "bloody diarrhea", think Shigella first, then E. coli
Shigella = Lactose negative
E. coli = Lactose positive

Since viruses are obligate intracellular parasites, how are They are grown in tissue cultures, embryonated eggs, or live animals
they cultivated in the lab?
The Family Enterobacteriaceae is considered facultative anaerobes
