Free BMS Funeral Service Microbiology and Pathology Questions and Answers

Question 1

Wine-Like Clusters?

Accepted Answer

Staphylococci

Answer

Staphylococci are a genus of Gram-positive bacteria that typically arrange themselves in irregular, grape-like or 'wine-like' clusters when viewed under a microscope. This characteristic morphology is a key identifying feature, distinguishing them from other bacteria like streptococci, which form chains. Staphylococcus aureus is a well-known pathogenic species within this genus.

Question 2

Which of the following is the reference point for determining how effective chemical disinfectants are?

Accepted Answer

Phenol

Answer

Phenol (carbolic acid) is historically used as the standard reference disinfectant against which the efficacy of other chemical disinfectants is measured. The 'phenol coefficient' is a value that compares the effectiveness of a disinfectant to that of phenol under specific conditions. A higher phenol coefficient indicates greater disinfectant potency, making phenol the reference point.

Question 3

Which of the following is a Chlamydia-related condition?

Accepted Answer

Psittacosis

Answer

Psittacosis, also known as parrot fever, is a zoonotic infectious disease caused by the bacterium *Chlamydia psittaci*. It is primarily transmitted to humans through contact with infected birds, particularly parrots, and can cause respiratory symptoms ranging from mild flu-like illness to severe pneumonia. This condition is directly related to the Chlamydia genus.

Question 4

Which of the following vectors transmits epidemic typhus, which is brought on by the Rickettsia Prowazekii and also known as petechial fever or putrid fever?

Accepted Answer

Mosquitoes

Answer

Epidemic typhus, caused by *Rickettsia Prowazekii*, is primarily transmitted by the human body louse (*Pediculus humanus humanus*). While mosquitoes are vectors for many other diseases (e.g., malaria, dengue), they are not known to transmit *Rickettsia Prowazekii*. Therefore, based on established medical microbiology, the primary vector for epidemic typhus is the body louse, not mosquitoes.

Question 5

Among the following, which one is not an STD?

Accepted Answer

Tularemia

Answer

Tularemia is a bacterial disease caused by *Francisella tularensis*, typically transmitted to humans through contact with infected animals, insect bites (ticks, deer flies), or contaminated food/water. Unlike Hepatitis B, HIV/AIDS, HSV, and Gonorrhea, which are all well-known sexually transmitted diseases, Tularemia is not primarily or commonly transmitted through sexual contact.
