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 ...
If Gram-negative, oxidase-positive diplococci are visualized on direct Gram stain of urethral pus (male genital infection), no further testing is needed to establish the diagnosis of gonorrhea infection. [40] [41] However, direct Gram stain of cervical swabs is not useful because the N. gonorrhoeae organisms are less concentrated in these samples.
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. [7]
The International Pathogenic Neisseria Conference (IPNC), occurring every two years, is a forum for the presentation of cutting-edge research on all aspects of the genus Neisseria. This includes immunology, vaccinology, and physiology and metabolism of N. meningitidis, N. gonorrhoeae and the commensal species. The first IPNC took place in 1978 ...
Proteose peptone, horse plasma, haemoglobin provide nutrients for the growth of N. gonorrhoeae and N. meningitidis. Phosphate buffers the medium. The selective supplement added contains the antibiotics vancomycin, colistin, nystatin and trimethoprim, to suppress the accompanying flora. Vancomycin is inhibitory for gram-positive bacteria.
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 ...
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).
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 ...
