A young patient became ill with mononucleosis that she contracted from drinking out of the same glass as her boyfriend who also had the disease.

The glass, an inanimate object, has caused the indirect transmission.

The inanimate transmitter is called:

Choice A rationale

Vectors are living organisms, such as mosquitoes, that transmit pathogens between humans or from animals to humans. An inanimate object like a glass is not a vector.

Choice B rationale

Fomites are inanimate objects that can carry and transmit pathogens, such as a glass, door handles, or medical instruments.

Choice C rationale

Prions are infectious proteins that cause neurodegenerative diseases, not inanimate objects that transmit infection.

Choice D rationale

Interferons are proteins produced by cells in response to viral infections and do not relate to the transmission of pathogens via inanimate objects. .

Choice A rationale

Normal flora does not function as cell rebuilders. They primarily exist in a symbiotic relationship with the host without directly participating in cell repair processes.

Choice B rationale

While some normal flora aid in digestion, they are not involved in blood production. Blood production is a function of bone marrow and not influenced by normal flora.

Choice C rationale

Normal flora play a crucial role in preventing the colonization of pathogens by competing for nutrients and space, thereby protecting the body from harmful microorganisms.

Choice D rationale

Normal flora do not manage the fluid balance of the body. Fluid balance is regulated by the kidneys and the body's endocrine system, not by the normal flora.
