Nonliving reservoirs of disease, such as a toothbrush, drinking glass, and needle, are called __________ .

Guida verificata passo dopo passo

Understand the concept of reservoirs in microbiology: reservoirs are sources where pathogens can live, multiply, and from which they can be transmitted to a host.

Differentiate between living and nonliving reservoirs: living reservoirs include humans and animals, while nonliving reservoirs are inanimate objects that can harbor pathogens.

Recall the specific term used for nonliving reservoirs of disease, which includes objects like toothbrushes, drinking glasses, and needles.

Identify that these nonliving reservoirs are commonly referred to as "fomites."

Conclude that the correct term to fill in the blank is "fomites," which are inanimate objects capable of transmitting infectious agents.

Concetti chiave

Ecco i concetti essenziali che devi comprendere per rispondere correttamente alla domanda.

Fomites

Fomites are nonliving objects or materials that can carry infectious agents and facilitate their transmission. Examples include toothbrushes, drinking glasses, and needles, which can harbor pathogens and contribute to the spread of disease.

Reservoirs of Infection

Reservoirs of infection are sources where pathogens normally live, multiply, and from which they can be transmitted to a host. These can be living organisms or nonliving objects (fomites) that maintain the pathogen in the environment.

Modes of Disease Transmission

Modes of disease transmission describe how pathogens spread from reservoirs to new hosts. Indirect contact transmission involves fomites, where pathogens are transferred via contaminated objects rather than direct person-to-person contact.
