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 ...
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.
A coccus (plural cocci, from the Latin coccinus (scarlet) and derived from the Greek kokkos (berry)), is any microorganism (usually bacteria) [1] whose overall shape is spherical or nearly spherical. [2] [3] [4] Coccus refers to the shape of the bacteria and can contain multiple genera, such as staphylococci or streptococci. Cocci can grow in ...
Chocolate agar showing Francisella tularensis colonies Comparison of two culture media types used to grow Neisseria gonorrhoeae bacteria. Known as overgrowth, the nonselective chocolate agar medium on the left, due to its composition, allowed for the growth of organismal colonies other than those of N. gonorrhoeae, while the selective Thayer–Martin medium on the right, containing ...
Gram stain of Neisseria gonorrhoeae showing characteristic diplococci morphology. Neisseria gonorrhoeae, the bacterium that causes the sexually transmitted infection gonorrhea, has developed antibiotic resistance to many antibiotics. The bacteria was first identified in 1879. [1]
Granger’s family and team have since confirmed that the 81-year-old rep is indeed at an independent living facility but denied reports that she is residing within the facility’s memory care ...
Twitching motility is a form of crawling bacterial motility used to move over surfaces. Twitching is mediated by the activity of hair-like filaments called type IV pili which extend from the cell's exterior, bind to surrounding solid substrates, and retract, pulling the cell forwards in a manner similar to the action of a grappling hook.
