Study Notes
Veterinary Parasitology I
- Course material covers definitions of parasites, parasitism, and parasitic diseases.
- The course is taught by Dr. Walid Darwiche at Lebanese University.
- Veterinary parasitology is the study of parasitic infections in animals.
- Animal diseases may have noninfectious or infectious origins.
- Noninfectious diseases include genetic defects, physiological abnormalities, structural dysfunction, injury, radiation, or poisoning.
- Infectious diseases are associated with invasive, self-replicating agents that occupy an animal's body.
- Studies in infectious diseases include microbiology, virology, bacteriology, mycology, and parasitology.
- Medical and veterinary protozoology encompasses single-celled eukaryotic organisms.
- Helminthology covers trematodes (flukes), cestodes (tapeworms), nematodes (roundworms), and other parasitic worms.
- Medical and veterinary entomology studies parasitic arthropods such as insects, ticks, and mites.
- Veterinary practices spend significant effort on parasite issues as parasites are often diagnosed in veterinary practices; what parasites veterinary practices often try to manage is covered in the course.
- Host-parasite relationships include mutualism, commensalism, and parasitism.
- Mutualism benefits both partners physiologically.
- Commensalism benefits one partner without harming the other.
- Parasitism harms the host; parasites live at the expense of the host.
- Parasites are classified into ectoparasites (live on the outside of the host) and endoparasites (live inside the host)
- Parasites can live on or in the host's tissues in an extracellular or intracellular fashion.
- Microparasites multiply within the host while macroparasites do not generally increase in number on or within the host.
- Different modes of parasitism, such as obligate, facultative, accidental, and erratic, are discussed in the context of parasitic diseases.
- Methods of transmission include ingestion, skin penetration, contact, predation, and transmission through the nostrils, external genitalia, and transplacental/transmammary routes.
- Parasites disseminate in the environment through water, fomites, and human interventions.
- Strategies parasites use to infect hosts are illustrated, like behavioral changes in the host
- Different terminologies used in parasitic diseases are presented, including epidemiology, endemic disease, epidemic disease, sporadic disease, pandemic, incubation periods, and prepatent periods.
- Concepts of parasitic diseases like hypobiosis, hibernation/ aestivation, diapause, parthenogenesis, schizogony, gametogony, syngamy, and sporogony.
- Nomenclature follows the combination of genus and species names.
- Parasites can be classified based on their reproductive behavior. (Microparasites and Macroparasites)
