10 Questions
There are four major categories of microorganisms that cause infection on humans
True
Commensal bacteria found in healthy humans have a significant protective role by causing infections
False
Pathogenic bacteria have greater virulence and cause infections
True
Match the following types of microorganism with their characteristics:
Bacteria = Can be commensal or pathogenic Viruses = Classified using the Nobel Prize-winning Baltimore system Fungi = Can cause infections in humans Parasites = Can be transmitted through vectors like mosquitoes
The Baltimore classification system was devised by biologist David Baltimore
True
The Baltimore classification system includes the categories - ds = Dou
False
Match the following types of infection with their definitions:
Endogenous infection = Caused by microorganisms normally present in the body Exogenous infection = Caused by microorganisms acquired from the environment Primary infection = Initial infection in a previously healthy individual Secondary infection = Occurs as a result of a primary infection weakening the immune system
Match the following components of the chain of infection with their descriptions:
Infectious agent = The microorganism causing the infection Reservoir = The habitat in which the infectious agent lives, grows, and multiplies Portal of exit = The way the infectious agent leaves the reservoir Mode of transmission = The way the infectious agent is transferred to a susceptible host
Match the following risk factors with their impact on susceptibility to infection:
Age = Decreased immune response in the elderly Chronic illness = Weakening of the immune system Immunosuppressive medications = Reduced ability to fight off infections Malnutrition = Lowered resistance to infections
Match the following infection control measures with their descriptions:
Hand hygiene = Critical in preventing the spread of infections in healthcare settings Standard precautions = Basic level of infection control that should be used for all patient care Personal protective equipment (PPE) = Includes gloves, gowns, masks, and eyewear to protect healthcare workers from exposure to infectious agents Environmental cleaning = Removal of infectious agents from the healthcare environment to prevent transmission
