Microreview5(Normal Bacterial Flora)

Front 1

What are the normal benefits of normal flora?

Back 1

They occupy attachment sites on the skin and mucosa and thus prevent colonization by pathogenic bacteria. They also supply nutrients.

Front 2

What is the predominant organism of the skin?

Back 2

S. epidermidis. It can be pathogenic when it implants on devices such as artificial heart valves and prosthetic joints.

Front 3

What common skin anerobe plays a role in the pathogenesis of acne.

Back 3

Propionibacterium acnes

Front 4

What is Viridans Streptococcus?

Back 4

It is of a common bacterial group, which is normally found in the oral cavity, and is the leading cause of subacute bacterial endocarditis.

Front 5

What do the anerobic bacteria of the GI tract, such as, Clostridium and Bacterioides, cause if aspirated?

Back 5

Lung abscess with potential ingestational pneumonia.

Front 6

S. aureus commonly colonizes the nose. TRUE/FALSE

Back 6

True

Front 7

What are some normal flora of the intestinal tract that are pathogenic?

Back 7

E.coli(UTI)
Bacterioides fragilis(peritonitis)
Enterococcus fecalis(UTI, endocarditis)
Pseudomonas aeruginosa(variety of nosocomial infections)

Front 8

Whena patient is treated with Clindamycin, and eventually develops a pseudomembranous colitis, what organism is likely suspected?

Back 8

Clostridium difficile

Front 9

Lactobacillus species is the predominant bacteria in normal vaginal flora. TRUE/FALSE

Back 9

TRUE. Candida albicans is suppressed if the Lactobacillus is properly populated.

Front 10
