16 Questions
Which branch of science is concerned with the study of causative agents causing infectious diseases in humans?
Clinical Microbiology
Which type of microorganism is responsible for causing infectious diseases?
All of the above
What term is used to denote the populations of microorganisms that inhabit the skin and mucous membranes of healthy normal persons?
Normal microbial flora
Which type of flora consists of relatively fixed types of microorganisms regularly found in a given area at a given age, and promptly re-establishes itself if disturbed?
Resident flora
What term is used for microorganisms that inhabit the skin or mucous membranes for hours, days, or weeks?
Transient flora
Which branch of science specifically focuses on laboratory diagnosis and specific treatment of infectious diseases?
Clinical Microbiology
What is the main difference between colonization and infection?
Colonization does not involve invasion or cause damage, while infection involves invasion and causes damage.
In a healthcare setting, which component is required for infection spread?
Source of infectious agents, susceptible person, and transmission
How do germs move to the susceptible person in indirect transmission?
Through biological or mechanical vectors
Which factor is NOT considered a component required for infection spread in a healthcare setting?
Healthy environment
What is the main characteristic of a colonized patient?
They are a source of infection despite being infected (carrier state).
Which type of transmission involves respiratory droplets or body fluids?
Direct transmission
What is the role of a mechanical vector in the indirect transmission of germs?
It carries the pathogen within its body without being infected.
What is the significance of transient microorganisms in the absence of disturbance to the resident flora?
They are generally harmless and do not interact with the resident flora.
What is the main characteristic of pathogenesis of infection when microbes find a new host?
They multiply causing colonization without tissue invasion.
What is the primary risk factor for disease transmission in healthcare facilities?
Presence of susceptible individuals with compromised immune systems.
