Where do gonococci initially infect 
Select and explain. 
A. Vagina, B. Cervix, C. Uterus, D. Fallopian tubes
B: Cervix
Answer: B: Cervix 
Explanation: In women, the initial gonococcal infection involves the urethra and cervix uteri. The vaginal mucosa is not affected in adults because the stratified squamous epithelium is resistant to infection by cocci and also due to the acidic pH of vaginal secretion. The infection spreads to Baholin's, endometrium and fallopian tubes. Rarely peritonitis may develop with perihepatic inflammation (Fitz-Hugh-Cuis syndrome) Reference: Textbook of Microbiology; Anathanarayan and panicker's; 10th edition; Page no: 235
