Learn the important types of parasitic infection in veterinary parasitology including auto infection, congenital infection, zoonoses, epidemiology, parasitosis, and more with definitions and examples.
Parasitic adaptations are specialized morphological, anatomical, and physiological modifications that enable organisms to survive, feed, reproduce, and complete their life cycle within or on a host.
The mode of nutrition in protozoa may be holozoic, saprozoic, or pinocytosis. Different protozoan parasites obtain nutrients from the host by different methods depending upon their structure and habitat.
Reproduction is an essential biological process that enables parasites to survive, multiply, and complete their life cycles. Parasites exhibit both asexual and sexual modes of reproduction, which help in rapid multiplication, adaptation, transmission, and survival within hosts and vectors.
A host is an organism that harbors and nourishes a parasite. Hosts play an essential role in the life cycle, survival, and transmission of parasites. Based on the developmental stage of the parasite and its biological relationship with the host, hosts are classified into different types in parasitology.
The classification of parasites is based on their association with the host, duration of parasitism, location in the body, number of hosts required to complete the life cycle, and host spectrum. Major types include obligate parasites, facultative parasites, ectoparasites, endoparasites, monoxenous parasites, and heteroxenous parasites.
The relationship between parasites and their hosts may vary in duration and degree of dependence. Based on the nature of association with the host, parasites may show either loose association or permanent association.
Veterinary Parasitology is a branch of Parasitology, which deals with parasites that parasitize domestic and wild animals. Animal parasites are causing huge economic losses in terms of mortality, reduced weight gain, milk yield, hide quality and egg production and cost of control.
