Streptococcus pyogenes is a species of Gram-positive, aerotolerant bacteria in the genus Streptococcus. These bacteria are extracellular and made up of non-motile and non-sporing cocci (round cells) that tend to link in chains.

Streptococcus pyogenes is a species of Gram-positive, aerotolerant bacteria in the genus Streptococcus. These bacteria are extracellular and made up of non-motile and non-sporing cocci (round cells) that tend to link in chains. They are clinically important for humans, as they are an infrequent, but usually pathogenic, part of the skin microbiota that can cause Group A streptococcal infection. S. pyogenes can cause a variety of diseases such as streptococcal pharyngitis, rheumatic fever, rheumatic heart disease, and scarlet fever.

Laboratory diagnosis of Streptococcus pyogenes can be done using several methods, including microscopy, culture, rapid antigen test, and molecular tests such as polymerase chain reaction (PCR). Specimens for bacteriological investigations can include pus or exudate. Gram staining of pus or exudate iRead more
Laboratory diagnosis of Streptococcus pyogenes can be done using several methods, including microscopy, culture, rapid antigen test, and molecular tests such as polymerase chain reaction (PCR). Specimens for bacteriological investigations can include pus or exudate. Gram staining of pus or exudate is a rapid and presumptive diagnostic procedure. A throat swab culture is the most specific method for diagnosis. A swab sample from your throat can be tested for the presence of S. pyogenes using a rapid antigen test or PCR test. Is
