Group A streptococcal infections are a number of infections with Streptococcus pyogenes, a group A streptococcus (GAS). [1] S. pyogenes is a species of beta-hemolytic Gram-positive bacteria that is responsible for a wide range of infections that are mostly common and fairly mild. If the bacteria enters the bloodstream, the infection can become ...
The evolution of bacteria on a "Mega-Plate" petri dish A list of antibiotic resistant bacteria is provided below. These bacteria have shown antibiotic resistance (or antimicrobial resistance). Gram positive Clostridioides difficile Clostridioides difficile is a nosocomial pathogen that causes diarrheal disease worldwide. Diarrhea caused by C. difficile can be life-threatening. Infections are ...
Chains of S. pyogenes bacteria (orange) at 900× magnification Gram stain of Streptococcus pyogenes. Unlike most bacterial pathogens, S. pyogenes only infects humans. Thus, zoonotic transmission from an animal (or animal products) to a human is rare. [8] S. pyogenes typically colonizes the throat, genital mucosa, rectum, and skin. Of healthy ...

Streptococcal pharyngitis, also known as streptococcal sore throat (strep throat), is pharyngitis (an infection of the pharynx, the back of the throat) caused by Streptococcus pyogenes, a gram-positive, group A streptococcus. [9] [10] Common symptoms include fever, sore throat, red tonsils, and enlarged lymph nodes in the front of the neck.
Phenoxymethylpenicillin, also known as penicillin V (PcV) and penicillin VK, is an antibiotic useful for the treatment of a number of bacterial infections. [2] Specifically it is used for the treatment of strep throat, otitis media, and cellulitis. [2]
Streptococcus pneumoniae is a bacterium that causes respiratory infections. [4] Streptococcus pyogenes (also known as group A Streptococcus) is a bacterium that can cause a variety of pathologies, including impetigo and strep throat, as well as other, more serious, illnesses. [18] [19]
The severity of this disease frequently warrants immediate medical treatment. TSS is caused primarily by some strains of Staphylococcus aureus and Streptococcus pyogenes that produce exotoxins. Nevertheless, invasive GBS infection can be complicated, though quite infrequently, by streptococcal toxic shock-like syndrome (STLS).
