Neisseria gonorrhoeae, also known as gonococcus (singular) or gonococci (plural), is a species of Gram-negative diplococci bacteria first isolated by Albert Neisser in 1879. [3] An obligate human pathogen, it primarily colonizes the mucosal lining of the urogenital tract; however, it is also capable of adhering to the mucosa of the nose, [ 4 ...
N. gonorrhoeae has a high affinity for horizontal gene transfer, and as a result, the existence of any strain resistant to a given drug could spread easily across strains. [citation needed] Cases of Neisseria Gonorrhoeae with decreased susceptibility or resistance to antibiotics (2017-2018).
Neisseria gonorrhoeae is a sexually transmitted pathogen that causes gonorrhea, a sexually transmitted disease that can result in discharge and inflammation at the urethra, cervix, pharynx, or rectum. [4] It can cause pelvic pain, pain on urination, penile and vaginal discharge, as well as systemic symptoms.
The Neisseriaceae are a family [2] of Pseudomonadota, within the Neisseriales order of Betaproteobacteria.While many organisms in the family are mammalian commensals or part of the normal flora, the genus Neisseria includes two important human pathogens, specifically those responsible for gonorrhea (caused by N. gonorrhoeae) and many cases of meningitis ("meningococcal meningitis", caused by N ...
Neisseria gonorrhoeae is a gram negative diplococcus (also referred to as "Gonococcus") and a pathogenic bacteria. [2] In 2019, there were 616,392 reported cases of gonorrhea in the United States, with an overall increased rate 5.7% from 2018 to 2019. [6]
[1] [2] This medium is superior to other media generally employed for the isolation of Neisseria species. [1] [4] [5] The transparent nature of the medium helps in studying the colonial types. [6] Proteose peptone, horse plasma, haemoglobin provide nutrients for the growth of N. gonorrhoeae and N. meningitidis. Phosphate buffers the medium.
Comparison of two culture media types used to grow Neisseria gonorrhoeae bacteria. Known as overgrowth, note that the non-selective chocolate agar medium on the left, due to its composition, allowed for the growth of organismal colonies other than those of Neisseria gonorrhoeae, while the selective Thayer–Martin medium on the right, containing antimicrobials that inhibit the growth of ...
Neisseria is a large genus of bacteria that colonize the mucosal surfaces of many animals. Of the 11 species that colonize humans, only two are pathogens , N. meningitidis and N. gonorrhoeae . Neisseria species are Gram-negative bacteria included among the Pseudomonadota , a large group of Gram-negative forms.
