Streptococcus pyogenes is an aerobe and facultative anaerobe that grows best at an optimum temperature of 37°C and an optimum pH of 7.2. It requires enriched media for growth, such as blood agar, where it produces small (0.5-1mm), circular, semi-transparent colonies that produce a wide zone of β-hemRead more
Streptococcus pyogenes is an aerobe and facultative anaerobe that grows best at an optimum temperature of 37°C and an optimum pH of 7.2. It requires enriched media for growth, such as blood agar, where it produces small (0.5-1mm), circular, semi-transparent colonies that produce a wide zone of β-hemolysis. Growth and hemolysis are promoted by 5-10% CO2. Virulent strains, on fresh isolation form lesions, and produce a ‘matt’ (finely granular) colony while avirulent strains form ‘glossy’ colonies.

Streptococcus pyogenes is a Gram-positive bacterium. This means that it retains the crystal violet stain used in the Gram staining procedure, and appears purple or blue under a microscope.

Neisseria gonorrhoeae, also known as gonococcus, is a Gram-negative non-motile diplococcus that is intracellular. It is an aerobe and grows well at an optimum temperature of 37°C on chocolate agar. It produces small, grayish, and granular colonies with slight umbonation on Modified Thayer Martin medium, circular, convex, grayish, or colorless colonies on New York City medium, and opaque, convex, and gray-white colonies on other media. It is positive for cytochrome oxidase.

Neisseria gonorrhoeae, also known as gonococcus, is a Gram-negative bacterium. This means that it does not retain the crystal violet stain used in the Gram staining procedure, and instead takes up the counterstain, safranin, and appears pink or red under a microscope.

Diagnosis of Neisseria gonorrhoeae infection can be done through several methods, including culture, Gram stain, and nucleic acid tests, such as polymerase chain reaction, of a urine sample, urethral swab, or cervical swab.

Diagnosis of Neisseria gonorrhoeae infection can be done through several methods, including culture, Gram stain, and nucleic acid tests, such as polymerase chain reaction, of a urine sample, urethral swab, or cervical swab. Chlamydia co-testing and testing for other STIs is recommended due to high rates of co-infection. The specimen choice and collection method depend on the testing technique used in a laboratory and the age, sex, and sexual orientation of the patient. For example, for urethral specimens, urethral exudates can be expressed when patients have discharge. If there is no discharge, a thin, water-moistened swab can be inserted into the distal urethra to collect a sample.

Neisseria gonorrhoeae, also known as gonococcus, is a species of Gram-negative diplococci bacteria that causes the sexually transmitted genitourinary infection gonorrhea as well as other forms of gonococcal disease including disseminated gonococcemia, septic arthritis, and gonococcal ophthalmia neonatorum. Gonorrhoeal infection is generally limited to superficial mucosal surfaces lined with columnar epithelium. Pili and Opa proteins facilitate adhesion of the gonococcus to epithelial cells of the urethra, rectum, cervix, pharynx, and conjunctiva, thereby making colonization possible.
