Question

Profuse, yellowish, greenish, frothy, smelling discharge from the vagina is due to infection of
(a) Treponema pallidum
(b) Chlamydia
(c ) Trichomonas vaginalis
(d) Neisseria

Answer 1

Hint: Profuse, yellowish, greenish, frothy, smelling discharge from the vagina are the symptoms of a parasitic infection. The parasite belongs to a group of eukaryotic unicellular organisms bearing flagella as their locomotory apparatus.

Complete answer:
Trichomonas vaginalis is a parasite that belongs to the kingdom of Protozoa. It is flagellated and anaerobic. It is a cause of vaginitis where the inflammation of the vagina and vulva is observed. Symptoms of this infection in females include profuse yellowish- greenish frothy discharges from the vagina with a musty smell.

Additional Information:
-Treponema pallidum is a bacterium that causes syphilis in humans. It spreads through sexual transmission. It is a gram-negative bacteria and an obligate parasite. These spiral-shaped bacteria are microaerophilic i.e require a small amount of oxygen for survival. It enters through intact skin or abraded skin, followed by invasion and colonization in different parts of the body such as mucus membrane, central nervous system via the vascular system of blood. In syphilis, inflammation of urogenital tracts occurs and its therapy usually involves doses of antibiotics such as penicillin and tetracycline.
-Chlamydia is also a sexually transmitted disease that is spread by a bacteria named Chlamydia trachomatis. Its symptoms include pain while urinating and discharges from the vagina or penis.
-The urogenital tract in men is often infected by a bacteria named Neisseria gonorrhoeae. It is also transmitted by sexual intercourse and thus regarded as a sexually transmitted disease.

So, the correct answer is ‘Trichomonas vaginalis.’

Note: Sexually transmitted diseases or STDs are diseases or infections which are transmitted through sexual contact. They may also spread through the usage of shared needles or breastfeeding by an affected mother. They are also known as Venereal diseases(VDs) or Reproductive Tract Infections(RTIs).
