**Question:** Friedlander's bacillus is the eponym of
A. Neisseria gonorrhoeae
B. Salmonella typhi
C. Haemophilus influenzae
D. Streptococcus pyogenes
**Correct Answer:** A. Neisseria gonorrhoeae
**Core Concept:**
Friedlander's bacillus refers to Neisseria gonorrhoeae, a Gram-negative bacterium that is the causative agent of gonorrhea, a sexually transmitted infection (STI). Friedlander's bacillus is named after the German pathologist, Robert Koch, who initially identified the organism in 1879.
**Why the Correct Answer is Right:**
N. gonorrhoeae is the correct answer because it is the specific bacterium associated with gonorrhea, a disease characterized by inflammation of the male and female genital tracts, urethra, cervix, and cervicovaginal discharge in women. This bacterium causes genital infections and is transmitted through sexual contact.
**Why Each Wrong Option is Incorrect:**
A. Neisseria gonorrhoeae is not the correct answer for Salmonella typhi as Salmonella typhi is responsible for causing typhoid fever, a different disease transmitted through contaminated food or water.
B. Neisseria gonorrhoeae is incorrect for Streptococcus pyogenes, which is related to group A streptococcal infections, such as strep throat and impetigo, not gonorrhea.
C. Neisseria gonorrhoeae is also incorrect for Haemophilus influenzae, which causes respiratory tract infections, meningitis, and other diseases, not gonorrhea.
**Clinical Pearl:**
Gonorrhea is a crucial topic in clinical medicine as it is a common STI, requiring prompt diagnosis and treatment to prevent complications like pelvic inflammatory disease (PID), ectopic pregnancy, and infertility in both men and women. Early diagnosis and treatment of gonorrhea are essential for patient care and public health.
