The bacteria are known to infect the living organisms including humans. The streptococci is a gram negative bacteria and spherical in shape. This bacteria causes different infections in the humans.
Trimethoprim-sulfamethoxazole (SXT) is the combinational drug used for the treatment of the infections caused by the different bacteria. The different infections that can be treated by this drug are urinary tract infection, ear infection and shigellosis. β-Hemolytic streptococci that causes tonsillopharyngitis can be treated by this drug.
Beta hemolytic or complete hemolysis termed on the characteristic of the complete lysis of red cells due to the enzyme streptolysin, under the colonies. These are leads to the particular area to be transparent and lightened.
Beta hemolytic streptococci are one type of beta-hemolytic bacteria that are fall in group A streptococci, these bacteria produce an exotoxin enzyme. Bacitracin with trimethoprim-sulfamethoxazole disks is used to differentiate these streptococci.
Thus, the correct answer is - β-Hemolytic streptococci.
HIV (human immunodeficiency virus) is a virus that attacks a type of white blood cell called a T-helper cell (also called a CD4 cell). People who have been infected with HIV develop AIDS. People with AIDS often develop diseases caused by organisms that usually do not harm people who are not infected with HIV. Explain why the organisms are more harmful to people with HIV than to people without HIV
