Is Streptococcus pyogenes always Beta hemolytic?
Almost always - stress on 'almost'. There are sporadic cases of nonhemolytic or alpha hemolytic S. pyogenes. So beta hemolysis is usable for quick screens, but is not 100% percent reliable.
What shape does bacteria have in the streptobacillus?
All species of genus Streptococcus (family Streptococcaceae, order Lactobacillales, class Bacilli, phylum Firmicutes, kingdom Bacteria) are, as the name suggests, cocci. That is to say: round shaped.They are also generally found in chains rather than individuals.They are gram positive and there are several hemolytic strains (although there are some non-hemolytic streptococci.)
Why does addition of a bacitracin disk to a blood plate make a rapid identification technique?
In terms of beta hemolytic streptococcus they usually plate this bacteria on blood agar bc when it grows it forms small colonies (bc gram +) with a clear halo around it bc it is hemolytic...this is not the only bacteria to cause hemolysis in blood agar so one might put a bacitracin disk in the plate and bc this inhibits growth of beta hemolytic strep if you see small colonies with clear halos growing everywhere but near the bacitracin disk then this too is indicative of id-ing this bacteria as beta hemolytic strep...hope this helps...enjoy:)
List genus and species of two gram positive pathogenic bacteria that are hemolytic and the disease they cause in humans.?

What is the name of the medium used to culture bacteria that is thought to be strep?

Can alpha-hemolytic streptococci cause infective endocarditis?

from the streptococcus genus but i dont know which species specifically... it may well be a few streptococcus species :)
