MMSC 428 Exam 2 (100% Error-free Answers)

Neisseria gonorhoeae (gonococcus/ GC) correct answers -gram negative diplococci -facultative intracellular parasite (FIP) -very fragile outside of human host, do not tolerate temperature changes -capnophillic, 5% CO2 is ideal -fastidious -cannot grow above 37 C -humidity is required to prevent drying out -medium to small colonies -oxidase + -super oxol + -glucose + -chromogenic substrate enzymes + -commonly resistant to penicillin and tetracycline neiserria gonorrhoeae clinical manifestations correct answers -gonorrhea: common STD in the US, causes cervicitis or asymptomatic infection in females (no vaginal infection) and urethritis with puss discharge in males -pelvic inflammatory disease (PID): cervicitis in female goes untreated and bacteria spreads into the uterus and fallopian tubes, leading to inflammation, fluid build up, development of scar tissue that leads to infertility, low abdominal/pelvic pain, vaginal discharge and low grade fever -disseminated gonococcal infection (DGI): bacteria leaves the genital are and enters the bloodstream, leading to meningitis, septicemia (with cytokine storm), arthritis or skin lesions, more common in women progressing from PID -fitz hugh curtis syndrome: untreated infection allows bacteria to spread to area surrounding the liver and cause perihepatitis (no inflammation of the actual liver), more common in females following PID, not common in US -ophthalmia neonatorum: conjunctivtis seen in newborns who pass through the birth canal of a woman infected with gonorrhea, usually due to asymptomatic mother not knowing she's infected -pharyngitis: typically acquired from oral sex with partner infected with gonorrhea, not a common cause of bacterial pharyngitis -proctitis: inflammation of the rectum due to infection with N. gonorrheae, common in anal receptive sex and females whose infection spreads from cervix to anus due to close proximity neisseria meningitidis correct answers -usually infects by inhalation and establishes infection in upper respiratory tract, then spreads to the rest of the body -mainly treated with penicillin or chloramphenicol for meningitis -produces a very strong form of endotoxin -vaccines availible -gram negative -facultative intracellular parasite -fastidious -not capnophilic, but grows better with CO2 -not part of normal biota, when isolated is always significant -glucose +
