GONORRHEA
GONORRHEA
Definition Gonorrhea is referred to as purulent infection due to Neisseria gonorrhoeae, which mainly occurs in urogenital system, but may also present as gonorrheal ophthalmia, pharyngitis, rectitis, pelvic inflammation or disseminated infection

Etiology Pathogen is Neisseria gonorrhoeae, calling diplococcus gonorrhoeae or gonococcus for short, first found in stained smears from vaginal, urethral and conjunctival exudates in 1879 by Albert Neisser In acute phase of the infection, the pathogens are detected in cytoplasm of leukocytes in the discharges of the patients, while in chronic phase, extracellular gonorrhoeae are more often seen

Morphology and Staining The gonococcus is a Gram-negative, diplococcal, pink bacterium appearing kidney or lima bean shape

Growth property For optimal growth, it requires a moist medium with temperature of 35 C-36C, and a 3-5%co2 atmosphere Gonococcus is fastidious organism that grow well in culture media including animal protein gonococcus die easily in dry and hot circumstances normal disinfectant or soap can cause it lose motoricity a Biochemical event Gonococcus can create oxidase during growing process, so oxidase test is meaningful in initial diaganosis
Growth property • For optimal growth, it requires a moist medium with temperature of 35 ℃ -36 ℃, and a 3–5% CO2 atmosphere. • Gonococcus is fastidious organism that grow well in culture media including animal protein. • Gonococcus die easily in dry and hot circumstances • Normal disinfectant or soap can cause it lose motoricity. Biochemical event • Gonococcus can create oxidase during growing process, so oxidase test is meaningful in initial diaganosis
