Study of parasites
Parasitology
Organisms that live on and obtain nutrients from another organisms
Parasites
Living together, the association of two living organisms each different species
Symbiosis
Association of two different species of organisms that is beneficial to one and neutral to the other
Commensalism
Association of two different species that is beneficial toboth
Mutualism
Association of two different species of organism that is beneficial to one at the other’s expense
Parasitism
Relating to commensalism, the association between two different organisms in which one benefits and has a neutral effect on the other
Commensal
Parasite that has demomstrate the ability to cause disease
Pathogenic
Parasite that cannot survive outside the host
Obligatory
Parasite that is capable of existing indepentdently of a host
Facultative
Parasite that is established inside a host
Endoparasite
Parasite that is established in or exterioir sirface of host (skin,nails)
Ectoparasite
1host required for the larva
Transitory
1host for both larva and adult
Permanent
2 or more host, 1 or 2 for larva and 1 for adult
Periodic
Occurs in an unusual host
Incidental
Occurs in unusual habitat
Erratic
Primarily infect animals but may cause infection to man
Zoonatic
Visits host only during feeding time, does not live on body
Intermittent
Free- living organisms that passes through the digestive tract without infecting the host
Spurious
Host responsible for transferring a parasite from one location to another
Transport
Parasite- harboring host that is not exhibiting clinical symptoms but can infect others
Carrier
Harbors a parasite that does not develop but remains alive
An animal host
Serve to bring parasite to it true host
Paratenic
Host other than the normal one that is harboring a parasite
Accidental/ incidental
Host in which the ADULT secual phase of parasite develops
Definitive
Host in which is LARVAL sexual phase of parasite develops
Intermediate
Host that harboring parasites that are parasitic for humans and from which humans may become infected
Reservoir
Transmits parasites only after the latter has completed its development within the hist
Biologic
Aka PHORETIC vector
ONLY transmits the parasites
Mechanical
Process of inoculating an infective agent
Exposure
Establishments of the infective agent in the hist
Infection
Period between infection and evidence of symptoms
Incubation period
Results when an infected individual becomes his own direct source of infection
Autoinfection
Happens when the already infected individual is further infected with the same species leading to massive infection with the parasite
Superinfection or hyperinfection
Most common source of infection
Contaminated soil and water
Food
Arthropods
Other animals
Another person
Common components
Mode of transmission
Infective stage
Diagnostic stage
Route a parasite follows
When on or on the human body
Independently of the human body
Means whereby a parasite gains entry into an unsuspecting host
Mode of transmission
Morphologic form that invades humans
Infective stage
Ine or more forms that can be detected via laboratory retrieval methods
Diagnostic stage
Other mode of transmission
Skin inoculation
Insect bites
Congenital transmission
Inhalation of airborne eggs
Sexual intercourse
When in or on the human body
Provides an understanding of the symptomatology and pathology of the parasite
Independently of the human body
Provides crucial information pertinent to epidemiology prevention and control
Types of parasites
Obligatory
Facultative
