Hepatitis B is not a bacterial disease, its a viral diseas..
Hepatitis B virus is not a gram-negative or gram-positive bacterium because it is a virus, not a bacteria. Viruses do not have cell walls like bacteria, so they are not classified as gram-negative or gram-positive.
Bacillus subtilis is generally able to grow on Mannitol Salt Agar (MSA) because it is a non-fermenter of mannitol. Most Bacillus species, including B. subtilis, are not able to ferment mannitol, so they can grow on MSA but will not change the color of the agar.
Bacillus subtilis typically forms large, dry, irregular colonies with a matte appearance on MYP agar, while Staphylococcus aureus usually forms small, smooth, shiny colonies. Additionally, B. subtilis is often motile and may exhibit rhizoid growth patterns, while S. aureus is non-motile. A Gram stain can also be useful, as B. subtilis is Gram-positive and S. aureus is Gram-positive.

Listeria does not belong because it is a facultative intracellular pathogen, while the others are commonly found in the environment and can form normal part of the human microbiota.

gram positive Exactly. When doing a gram stain on B. subtilis, this bacterium resists decolorization (keping the first stain and NOT taking on the color of the secondary stain). Therefore, this bacterium is gram (+).
It's part of the Bacillus species, which also includes B. cereus (a common bacteria in food poisoning known for being present in poorly reheated rice). These two bacteria are spore forming gram positive bacilli (rods).
Yes it is. Bacillus subtilis produces endospores?
yes
no
I'm a hepatitis B positive guy, its possible to get working vissa in London
Bacillus bacteria typically do not grow well on Eosin Methylene Blue (EMB) agar because they are gram-positive bacteria. EMB agar is designed to inhibit the growth of gram-positive bacteria and isolate gram-negative bacteria, such as Escherichia coli.
This indicates that the person who has antibodies reactive to the Hepatitis B or C virus and likely has been exposed to the disease (and likely has it).
Approximately 20,000 infants are born each year to mothers who test positive for the hepatitis B virus.
