What is the size range of adenoviruses?
1) 50-100 nm
2) 70-75 nm
3) 100-150 nm
4) 200-300 nm
General Microbiology Answer: 2Adenoviruses are medium-sized viruses that typically range from 70 to 90 nanometers in diameter, with the most common size being around 70-75 nm. They are known for causing respiratory infections and conjunctivitis
What is the correct color coding for bio-medical waste that requires incineration or deep burial?
1) Red
2) Yellow
3) Blue/white translucent
4) Black
General Microbiology Answer: 2
Yellow is the designated color for bio-medical waste that is considered hazardous and requires incineration or deep burial. This classification helps in the proper disposal of infectious and potentially harmful materials.
What type of antibodies are known as "coproantibodies"?
1) IgA
2) IgM
3) IgG
4) Antibodies found in feces
General Microbiology Answer: 4Copro antibodies are antibodies found in feces These are typically IgA antibodies that are produced in response to infections in the gastrointestinal tract, including typhoid fever. They can be detected in stool samples and are used in diagnostic tests.
What is the purpose of the puncture-proof container in bio-medical waste management?
1) To contain sharps
2) To hold non-infectious waste
3) To store chemicals used for disinfection
4) To transport pathological waste
General Microbiology Answer: 1
The purpose of the puncture-proof container in bio-medical waste management is to contain sharps, preventing injuries and contamination.
What is the primary cause of cutaneous anthrax?
1) Inhalation of spores
2) Entry through the skin
3) Ingestion of contaminated food
4) Contact with infected animals
Cutaneous anthrax is primarily caused by entry through the skin, often through abrasions or cuts.
Which of the following is a killed viral vaccine?
1) Sabin vaccine for poliomyelitis
2) Salk vaccine for poliomyelitis
3) MMR vaccine for measles, mumps, rubella
4) Varicella-zoster
General Microbiology Answer: 2
The Salk vaccine for poliomyelitis is a killed viral vaccine, effectively preventing the disease by using inactivated poliovirus.
What is the effect of Actinomycin D on orthomyxoviruses?
1) Stimulates multiplication
2) Inhibits multiplication
3) No effect
4) Enhances stability
General Microbiology Answer: 2Actinomycin D is an antibiotic that inhibits RNA synthesis. In the case of orthomyxoviruses, it effectively inhibits their multiplication by preventing the transcription of viral RNA, thereby blocking the virus ability to replicate. Actinomycin D inhibits the multiplication of orthomyxoviruses by blocking RNA synthesis, which is crucial for viral replication.
