Alpha hemolytic means that the agar plate that contains blood (blood agar) shows a partial breakdown of the red blood cells by the microbe. Cocci is the shape of the bacteria which can be in clusters or clumps like a bunch of grapes or they can be in a sting-like formation. This string-like formation are called streptococci. This cocci could be S. viridians or S. penumoniae.
gamma/alpha hemolysis
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.
Yes, cocci is only the shape of the bacteria. There are many types of cocci bacteria that can be found in animals. Cocci bacteria is round or circular.
Bacteria that look like cocci but are not true cocci
Cocci are spherical bacteria. As such, they do not have flagella, or tails that allow other types of bacteria to move on their own. Most cocci are not capable of locomotion.
Alpha-hemolytic strep is one class of streptococcus bacteria that does cause infective carditis (IE). Viridans Streptococcus, a specific strain of Alpha-hemolytic streptococcus is a cause of IE.

among many drugs causing hemolytic anemia one is Alpha methyl dopa a centrally acting antihypertensive used most in pregnant womens to control blood pressure.

Normal results would include finding organisms that grow in healthy throat tissues. These organisms include non-hemolytic and alpha-hemolytic streptococci, some Neisseria species, staphylococci, diphtheria and hemophilus organisms.
This occurs when there is partial damage to the red blood cells. The plate will turn green. This is characteristic of streptococcus pneumonia.
Cocci and bacilli do not cause chlamydia. Cocci cause gonorrhea.
Yes, cocci is only the shape of the bacteria. There are many types of cocci bacteria that can be found in animals. Cocci bacteria is round or circular.
Cocci means round.
