Molecular epidemiology of infectious
diseases questions with verified answers
1: What is molecular epidemiology? - correct answer -
Molecular epidemiology is a branch of epidemiology that uses molecular
biology techniques to study the distribution and determinants of disease in
populations.
2: How does molecular epidemiology differ from traditional epidemiology? -
correct answer - Molecular epidemiology incorporates molecular and genetic
data, such as DNA, RNA, and protein analyses, to understand disease
patterns, whereas traditional epidemiology relies on observational and
statistical methods.
3: What is the primary goal of molecular epidemiology in infectious
diseases? - correct answer - The primary goal is to identify the molecular
mechanisms by which infectious agents cause disease and to understand the
genetic factors that influence susceptibility and resistance.
,4: What type of molecular techniques are commonly used in molecular
epidemiology? - correct answer -
Techniques include polymerase chain reaction (PCR), sequencing,
genotyping, and molecular cloning.
5: What is PCR, and why is it important in molecular epidemiology? - correct
answer -
PCR (Polymerase Chain Reaction) is a technique used to amplify small
segments of DNA. It is important because it allows for the detection and
analysis of genetic material from pathogens.
6: How can molecular epidemiology help in outbreak investigation? - correct
answer -
It can identify the source and transmission pathways of infectious agents,
enabling targeted interventions to control the outbreak.
7: What is genotyping, and how is it used in molecular epidemiology? -
correct answer - Genotyping is the process of determining the genetic
makeup of an organism. In molecular epidemiology, it is used to
differentiate between strains of pathogens.
, 8: What role does next-generation sequencing (NGS) play in molecular
epidemiology? - correct answer -
NGS allows for the rapid sequencing of entire genomes, providing detailed
information on pathogen evolution, diversity, and resistance mechanisms.
9: What is a phylogenetic tree, and how is it used in molecular
epidemiology? - correct answer - A phylogenetic tree is a diagram that shows
the evolutionary relationships among various biological species based on
their genetic characteristics. It is used to trace the origins and spread of
infectious diseases.
10: How can molecular epidemiology contribute to vaccine development? -
correct answer - By identifying specific genetic markers and antigens of
pathogens, molecular epidemiology can guide the design of effective
vaccines.
11: What is the significance of identifying genetic markers in pathogens? -
correct answer - Genetic markers can help in tracking the spread of
infections, understanding pathogen evolution, and developing targeted
treatments and vaccines.
