What is Cyclozoonosis?

Cyclozoonosis. a zoonosis that requires more than one vertebrate host (but no invertebrate) for completion of the life cycle; e.g., various taenioid cestodes such as Taenia saginata and t. Solium in which humans are an obligatory host; hydatid disease, a cyclozoonosis in which man is not an obligatory host.

What is Amphixenosis?

What is epizootic and enzootic?

Epizootiology deals with epizootic and enzootic levels of animal disease. An epizootic is defined as an outbreak of disease in which there is an unusually large number of cases, whereas an enzootic refers to a low level of disease that is constantly present in a population (Steinhaus, 1967; Onstad et al., 2006).

How did zoonotic disease spread?

In direct zoonosis the disease is directly transmitted from animals to humans through media such as air (influenza) or through bites and saliva (rabies). In contrast, transmission can also occur via an intermediate species (referred to as a vector), which carry the disease pathogen without getting sick.
