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 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.
Neisseria mucosa is a species of Neisseria.. It is notable among Neisseria for its ability to metabolize sucrose. [2] It can cause endocarditis. [3] While N. mucosa is a rather rare cause of endocarditis, cases of N. mucosa endocarditis have been reported along with symptoms such as painful finger nodules, fever, headache, and tremors.
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 ...
Considering that oral bacteria are transferred vertically from primary caregivers in early childhood, and horizontally between family members later in life, archaeological dental calculus is a unique way to trace population structure, movement, and admixture between ancient cultures, as well as the spread of disease.
Streptococcus mutans is a facultatively anaerobic, gram-positive coccus (round bacterium) commonly found in the human oral cavity and is a significant contributor to tooth decay.
Neisseria elongata is a Gram negative bacterium and is different from the other cocci shaped members of the genus Neisseria as it is rod shaped. [2] Unlike other Neisseria it is catalase negative. N. elongata is the most ancestral of the human Neisseria.
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]
