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 ...
[67] [68] In 2016, the WHO published new guidelines for treatment, stating "There is an urgent need to update treatment recommendations for gonococcal infections to respond to changing antimicrobial resistance (AMR) patterns of N. gonorrhoeae. High-level resistance to previously recommended quinolones is widespread and decreased susceptibility ...
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.
Gonorrhoea is a sexually transmitted infection (STI) caused by the bacterium Neisseria gonorrhoeae. [1]The World Health Organization (WHO) estimated that, in 2016, the global incidence rate was 20 per 1000 women and 26 per 1000 men, totaling 86.9 million new gonococcal infections among people between 15 and 49 years old.
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]
Gonococcemia (also known as "Disseminated gonococcal infection" [1]) is a rare complication of mucosal Neisseria gonorrhoeae infection, or Gonorrhea, that occurs when the bacteria invade the bloodstream. [2] It is characterized by fever, tender hemorrhagic pustules on the extremities or the trunk, migratory polyarthritis, and tenosynovitis. [3]
Infectious neonatal conjunctivitis is typically contracted during vaginal delivery from exposure to bacteria from the birth canal, most commonly Neisseria gonorrhoeae or Chlamydia trachomatis. [2] Antibiotic ointment is typically applied to the newborn's eyes within 1 hour of birth as prevention for gonococcal ophthalmia. [3]
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 ...
