Veterinary parasitology

Zoonosis

Veterinary medicine continues to be one of the most rapidly evolving health care professions of the twenty-first century. Veterinarians are responsible for many aspects of human health promotion and disease prevention, especially in the areas of food safety, environmental health, prevention and control of zoonotic diseases, and the human-animal bond. To accomplish these important missions, successful veterinarians along with their professional associates must learn to communicate effectively with a variety of individuals, ranging from health care professionals in other disciplines to print and electronic journalists to the day-to-day clients who walk off the street into the veterinary practice.

Technician's Note

Veterinarians and tech­nicians are responsible for many aspects of human health promotion and disease prevention.

One of the most important lines of communication, however, exists between veterinary practitioners and the members of their veterinary health care teams. Veterinary technicians serve as vital members of these health care teams. As such, these technicians must be able to understand and correctly use the nomenclature and terminology for almost every specialty discipline within veterinary medicine. This is especially true for the discipline of veterinary parasitology, the study of parasitic relationships affecting domesticated, wild, exotic, and laboratory animals and, to some extent, parasites that have the potential to be transmitted directly from animals to humans. If animal parasites are to be effectively treated and controlled, the veterinary technician must become “fluent” in the language of parasitology and be able to communicate effectively using the specialized terminology associated with these parasites and with the complex interactions between parasites and their animal hosts. This chapter assists the veterinary technician in acquiring fluency with regard to veterinary parasitology.

Symbiosis

Planet Earth is home to millions of species of diverse, living organisms that include plants, animals, fungi, algae, and unicellular organisms. Inevitably, there are millions of complex relationships taking place between and among these differing species. Many organisms live together in varied, intricate relationships. The term symbiosis (sym meaning “together” and biosis meaning “living,” thus “living together”) describes any association, either temporary or permanent, between at least two living organisms of different species. Each member of this association is called a symbiont. For example, lichen growing on the side of a tree (Figure 1-1) is actually a very complex symbiotic relationship between a fungus and an alga. Even the act of a human owning a dog and living with that dog is a type of symbiotic relationship. Tw...
