PPT-Arthropod-borne Viruses

Arthropodborne viruses arboviruses are viruses that can be transmitted to man by arthropod vectors Arboviruses belong to three families Togaviruses Bunyaviruses eg Sandfly Fever. What Are Blood borne Pathogens? Blood borne pathogens are microorganisms such as viruses or bacteria that are carried in blood and can cause disease in people.

They are not capable of surviving without a host cell (lack metabolic machinery). 2. They do, however, contain all the information necessary to direct metabolic processes. CLS 212: Medical Microbiology. History. Through the 1800s, many scientists discovered that something smaller than bacteria could cause disease and they called it . virion. (. Latin word- poison. )..

The food involved is usually contaminated with a disease pathogen or toxicant. . Such food contains enough pathogens or toxicant necessary to make a person sick..
