Question

Organism Causing LGV

• A. Chlamydia trachomatis
• B. Neisseria gonorrhoeae
• C. Treponema pallidum
• D. Haemophilus ducreyi

Answer 1

The Correct Option is A

In microbiology, Lymphogranuloma Venereum (LGV) is a sexually transmitted infection caused by specific strains of the bacterium Chlamydia trachomatis. To understand why Chlamydia trachomatis is the correct answer, let's explore the options:

• Chlamydia trachomatis: This bacterium is responsible for LGV, a disease characterized by genital ulcers and swollen lymph nodes. The LGV strains are different from those causing common chlamydial genital infections.
• Neisseria gonorrhoeae: This causes gonorrhea, a different sexually transmitted infection, and is not responsible for LGV.
• Treponema pallidum: The causative agent of syphilis, another distinct condition, not related to LGV.
• Haemophilus ducreyi: Known for causing chancroid, a different type of ulcerative sexually transmitted infection, not LGV.

Thus, the organism causing LGV is Chlamydia trachomatis.
