Micrococcaceae

Ingredients in Mannitol Salt Agar

Micrococcaceae is not ubiquitous

[blank_start]Staphylococcus aureus[blank_end] are the most common causes of osteomyelitis and acute bacterial endocarditis

[blank_start]Staphylococcus saprophyticus[blank_end] is a common cause of urinary tract infection in young females

Common infections of [blank_start]CNS[blank_end] include, UTI, bacterial endocarditis, infection of prosthetic joints, septicemiain immunosuppressed patients, wound infections and peritonitis.

[blank_start]food poisoning[blank_end] is due to ingestion of of pre-formed enterotoxin in food- microorganisms do not have to be present

If coagulase tube test clots up and becomes a jelly like substance what is it?

S. aureas commonly produces beta lactamase and renders penicillin useless

virulence factors for s. aureus include all of the following EXCEPT:

Which test is used to differentiate between Staph's and Strep's?

What common contaminant is isolated from blood cultures?

Superficial skin infection usually involving the face or legs, begins as red macule which progresses to a vesicle which ruptures and forms a yellow, thick crust. May spread and form multiple lesions, more prevalent in the summer months

Skin infection which begins abruptly after an incubation period of about a week. Begins with the sensation of tightness and burning at site of invasion, followed quickly by a patch of erythema which rapidly extends outward; may form blisters which may rupture, leaving raw weeping areas

An infection in a bone. Infections can reach a bone by traveling through the bloodstream or spreading from nearby tissue

S.Aureus Colony Morphology: Large, frequently [blank_start]yellow[blank_end], opaque, [blank_start]creamy[blank_end], smooth, shiny, domed, round. Often but not always [blank_start]beta[blank_end] hemolytic

Mrsa is slide coagulase neg or pos

CNS colony morphology- [blank_start]offwhite[blank_end], round, domed, [blank_start]smooth[blank_end], sometimes not as creamy as s.aureus, usually smaller colonies than s. aureus, usually non-hemolytic or beta

S. Sapticus colony morphology. often pigmented [blank_start]yellow[blank_end], opaque, [blank_start]sticky[blank_end], gummy, [blank_start]non-hemolytic[blank_end]

Stomatococcus mucilaginosus colony morphology: [blank_start]small[blank_end], domed, adherent, [blank_start]gray-brown[blank_end], tough, [blank_start]stringy[blank_end]
