Flashcards in Charlie- A-haemolytic streptococci Deck (8):
1

what are the 6 a-haemolytic streptococci

s.anginosis, s.mutans, s.mitis, s.salivarious, s.sanguinus, s.bovis

2

what is the characteristic feature of the following: s.angionosis

predilection to cause abscesses

3

what is the characteristic feature of the following: s.mutans

leading cause of dental caries. Forms slime on tooth enamel. Cleaves fructose to glucose, glucose also converted to lactic acid which decalcifies enamel leading to dental caries. May cause endocarditis if it enters the bloodstream

4

what is the characteristic feature of the following: s.mitis

common cause of non-hospital acquired infective endocarditis, can enter the blood stream through procedures.

5

exaplain endocarditis

infective emboli may break off from these vegetations and travel through the bloodstream to establish abscesses in others organs.

6

what is the characteristic feature of the following: s. saliverius

oral motuh flora, uncommon cause of invasive disease

7

what is the characteristic feature of the following: s. sanguinus

membrane of normal flora of oral cavity (antagonise the role of s.mutans in causing dental caries?), can cause bacteraemia nd septicaemia and maybe infective endocarditis if it enters the blood stream

8

what is the characteristic feature of the following: s.bovis

strongly correlated with undiagnosed colonic malignancy
