Question Answer
Define Infection.Disease caused by microorganisms- especially those that release toxins or invade body tissues.
Are microbes harmful in the colonization phase?No, they are harmless or they perform useful functions.
What are the 7 main sources of infections?Viruses,Bacteria, Protozoa, Fungi, Helminthes, Mycobacteria, and Prions.
What source of infection is incapable of living without a host?Viruses.
What source of infection is unicellular, animal-like microorganisms that are usually not harmful to humans?Protozoa.
What source of infection relatively complex and can reproduce on their own?Bacteria.
What source of infection generally comes in the form of worms?Helminthes.
What source of infection is a type of bacteria with fungal like properties?Mycobacteria.
