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.
What else can I help you with?
Is B subtilis gamma hemolytic?
No, Bacillus subtilis is not gamma hemolytic. It is known to be gamma-non-hemolytic, meaning it does not cause the breakdown of red blood cells and does not produce clear zones around colonies on blood agar plates.
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.
Is P aeruginosa alpha hemolytic?
P. aeruginosa is not alpha hemolytic. Hemolysis is used mainly for the identification of Streptococci and can be used for Staphylococci. P. aeruginosa can be mistaken for being alpha hemolytic because it produces a green diffusable pigment. This pigment is especially visible if grown in media with little to no pH dye indicators such as SIM tubes, nutrient broths (undisturbed), API strips, etc. A good way to tell the difference between diffusable pigment production and hemolysis is to look at the agar surrounding isolated colonies. Diffusable pigments should be alot more visible in areas with higher concentrations of bacteria (quadrant 1) and may not be seen around isolated colonies of 24 hour cultures. Hemolysis should be readily seen around isolated colonies regardless of incubation time. If left long enough, P. aeruginosa will eventually clear all the RBC in the agar around the colonies (beta hemolysis).
What is hemolytic streptococcus?
Hemolytic streptococcus is a group of bacteria that can cause various infections in humans, including strep throat, skin infections, and invasive diseases such as pneumonia and sepsis. These bacteria can be classified into different groups based on their hemolytic properties (alpha, beta, or gamma) when grown on blood agar plates. Beta-hemolytic streptococci are known for producing toxins that cause the breakdown of red blood cells.
Which cocci is motile?
None of the cocci bacteria are motile. Cocci are usually characterized by their round shape and they are typically non-motile.
Can alpha-hemolytic streptococci cause infective endocarditis?
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.
Is b subtilis hemolytic?
gamma/alpha hemolysis
What are the differences between beta and alpha hemolytic bacteria in terms of their hemolytic activity?
Alpha hemolytic bacteria partially break down red blood cells, causing a greenish discoloration on blood agar plates, while beta hemolytic bacteria completely break down red blood cells, leading to a clear zone around the bacterial colonies on blood agar plates.
Is B subtilis gamma hemolytic?
No, Bacillus subtilis is not gamma hemolytic. It is known to be gamma-non-hemolytic, meaning it does not cause the breakdown of red blood cells and does not produce clear zones around colonies on blood agar plates.

Erythromycin
What are 3 examples of bacteria their uses or harms and habitat and scientific names?
scientific names uses1. Streptococcus pyogenes beta hemolytic streptococci2. Streptococcus viridans alpha hemolytic streptococci3. Streptococcus pneumoniae pneumococci
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 is the antihypertensive drug causes hemolytic anemia?
among many drugs causing hemolytic anemia one is Alpha methyl dopa a centrally acting antihypertensive used most in pregnant womens to control blood pressure.
What characteristics does a normal throat culture have?
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.
Is P aeruginosa alpha hemolytic?

Are chlamydia cocci?
Cocci and bacilli do not cause chlamydia. Cocci cause gonorrhea.
What is the scientific name of cocci?
The scientific name for cocci is coccus (plural: cocci). They are a type of spherical-shaped bacteria.
