Document Summary

Hypha/ae - long branching structures; you will see this in moldy bread. Yeast- another way fungus can grow; spherical structures that grow by binary fission. Rna virus- a virus whose genome consists of rna. Enveloped- a virus that contains additional layers around the nucleocapsid. Normal flora- microorganism that reside in or on the body without causing disease. Carriers (people who have harmful germs living on or in their body, but are not visibly sick) Incubating period- the time between infection and signs/symptoms/illness. Latency period- the time delay between the moment something is initiated and the moment it becomes detectable. Fomite- a nonliving object that transmits disease. (a physical object that serves to transmit an infection from animal to animal) Vector- any agent (person, animal, microorganism) that carries and transmits a disease. Mechanical vector- an animal that transports an infectious agent but is not by it. Biological vector- disease-carrying organism, such as a rat, mosquito, or fly, that spreads infectious disease.
