  1. Toxic shock syndrome is caused by
    a) Infected BCG vaccine
    b) Infected measles vaccine
    c) Infected polio vaccine
    d) Infected DPT vaccine

Answer: Infected measles vaccine
Explanation:
Toxic shock syndrome (TSS) is an unfortunate but avoidable reaction of measles vaccine.
Measles vaccine does not have a preservative. Hence, once reconstituted it should not be kept beyond 2-3 hours & that too it should be kept on ice.
If it is not stored properly or is used after 2-3 hours there are chances of growth of pathogens, most important being staphylococci.
When infected, the staphylococcal toxin formed will lead to fever, diarrhea, vomiting, blood in stools, DIC, shock & ultimately death.
This usually follows use of multi-dose bulbs where the balance doses are not kept properly or not used in time.

  1. Which is not a synthetic pyrethroid?
    a) DDT
    b) Proparthrin

Answer: DDT
Explanation:
DDT (dichlorodiphenyltrichloroethane) is a colorless, crystalline, tasteless and almost odorless organo-chloride known for its insecticidal properties.
The Stockholm Convention, which took effect in 2004, outlawed several persistent organic pollutants, and restricted DDT use to vector control.
A pyrethroid is an organic compound similar to the natural pyrethrins produced by the flowers of pyrethrums. Pyrethroids now constitute the majority of commercial household insecticides.
Proparthrin, Cyper-methrin and Per-methrin are Pyrethroids.

  1. Given three genera of mosquitoes (Culex, Anopheles and Aedes) act as vector for which of the following diseases word wide?
    a) Malaria
    b) Dengue
    c) Filariasis
    d) Yellow fever

Answer: Filariasis

Filariasis is transmitted by all four genera of mosquitoes including Culex, Anopheles, Mansonoides and Aedes.
Lymphatic filariasis is caused by the worms Wuchereria bancrofti (Vector-Culex), Brugia malayi (Vector-Mansonoides), and Brugia timori.
Subcutaneous filariasis is caused by Loa loa (the eye worm), Mansonella streptocerca, and Onchocerca volvulus.
These worms occupy the subcutaneous layer of the skin, in the fat layer. L. loa causes Loa loa filariasis, while O. volvulus causes river blindness.
Serous cavity filariasis is caused by the worms Mansonella perstans and Mansonella ozzardi, which occupy the serous cavity of the abdomen.
