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 ...
Gonorrhoea or gonorrhea, colloquially known as the clap, [7] is a sexually transmitted infection (STI) caused by the bacterium Neisseria gonorrhoeae. [8] Infection may involve the genitals, mouth, or rectum. [9] Gonorrhea is spread through sexual contact with an infected person, [1] or from a mother to a child during birth. [1]
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.
[26] [27] Mycoplasma and Ureaplasma are frequently found in the vagina. Some of the obligate and facultative anaerobic bacteria are associated with BV. [46] Neisseria gonorrhoeae is found in the vagina and is considered a pathogen that is sexually transmitted. [51]
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 ...
The pathogenic bacteria able to carry out natural genetic transformation (of those listed in the table) are Campylobacter jejuni, Enterococcus faecalis, Haemophilus influenzae, Helicobacter pylori, Klebsiella pneumoniae, Legionella pneumophila, Neisseria gonorrhoeae, Neisseria meningitidis, Staphylococcus aureus, Streptococcus pneumoniae and ...
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).
He found work, however as an assistant of the dermatologist Oskar Simon (1845–1892), concentrating on sexually transmitted diseases and leprosy. During the following two years he studied and obtained experimental evidence about the pathogen for gonorrhea, Neisseria gonorrhoeae. Neisser was also the co-discoverer of the causative agent of leprosy.
