medical parasitology

human parasites and the diseases they cause

veterinary parasitology

animal parasites

structural parasitology

structure of proteins from parasites

quantitative parasitology

quantitative study of parasitism in a host population

ecological parasitology

ecological impact of parasites

interaction with their environment

hosts

harbors the parasite and provide nourishment

parasite

depend on host for survival

ectoparasite

lives outside

infestation

endoparasite

lives inside body

infection

parasites multiple within host

trauma or physical damage

due to direct physical damage

lytic necrosis

enzymes necessary to digest food

sedimentation

specific gravity—parasites are heavier

zinc sulfate floatation technique

specific gravity and sample debris

permanent stain

final step in microscopic examination

pathogenic stage

responsible for producing organs

infectious disease

abnormalities caused by different microorganism

pathogenecity

ability of organism to cause disease

virulence

magnitude of the disease caused

parasitology

dependence of one organism to another

parasitism

form of symbiosis

symbiosis

two unlike organism exists together

commensalism

two organism exists but one benefits

mutualism

two mutually benefits

definitive host

adult stage

final host in life cycle

intermediate host

larval stage

sexual phase occurs

reservoir host

vertebrae

additional source of infection

paratenic host

means of transport for parasite

facultative parasite

live independently of host

obligate parasite

must live inside host

permanent parasite

early life to maturity

intermittent parasite

visit host during feeding time

incidental parasite

occur in unusual host

transitory parasite

larvae develop in host

erratic parasite

seen in unusual organ
