    Neisseria gonorrhoeaeIntroductionNeisseria gonorrhoeae is the obligate human pathogen that causes gonorrhea, a sexually transmitted disease (STD). These Gram-negative diplococci/gonococci do not infect other animals or laboratory animals and do not survive freely in the environment. Gonococcal infection occurs in the upper or lower tract, pharynx, ophthalmic area, rectum and bloodstream. During the 1980s, gonorrhea was also called "the clap", at a time when public awareness was very minimal. It was one of the venereal diseases that prostitutes hoped to contract, as it led to infertility due to pelvic inflammatory disease (PID). As documentation, diagnostic testing, and public awareness have improved, incidence reports have decreased, but it is still considered a very common infectious disease. MeetSexually active men and women of all races, ages, and socioeconomic backgrounds are susceptible to gonococcal infection. However, among the infected population, the CDC reports that 80% of women and 10% of men are asymptomatic. After an incubation of five to seven days, males tend to exhibit symptoms of swelling of the urethra, painful and more frequent urination, and abnormal penal discharge of thick yellow exudate (pus). Similarly, women suffer from chronic abdominal pain, inflammation of the cervix, painful urination, bleeding or irregular menstrual cycles, fever and increased yellow vaginal discharge. Women have a higher risk factor, 60 to 90 percent, of becoming infected after just one sexual encounter. Both sexes suffer from sore throats during oral infections if they are not asymptomatic. However, this response is most often confused with a viral sore throat. , Hae-Sun Moon, Wolfgang, Matthew, van Putten, Jos PM, Dorward, David, Hayes, Stanley F. and Koomey, Michael.
