The definitive hosts for these Taenia species are canids. The adult tapeworms live in the intestines of animals like dogs, foxes, and coyotes. Intermediate hosts such as rabbits, goats, sheep, horses, cattle and sometimes humans get the disease by inadvertently ingesting tapeworm eggs (gravid proglottids) that have been passed in the feces of an infected canid.
Sheep and goats are both small ruminants with cosmopolitan distributions due to their being kept historically and in modern times as grazers both individually and in herds in return for their production of milk, wool, and meat. [1] As such, the diseases of these animals are of great economic importance to humans.
Dictyocaulus viviparus found in the bronchi of a calf during necropsy (arrow). Parasitic bronchitis, also known as hoose, husk, or verminous bronchitis, [1] is a disease of sheep, cattle, goats, [2] and swine caused by the presence of various species of parasite, commonly known as lungworms, [3] in the bronchial tubes or in the lungs.
Orf is a zoonotic disease, meaning humans can contract this disorder through direct contact with infected sheep and goats or with fomites carrying the orf virus. [6] It causes a purulent-appearing papule locally and generally no systemic symptoms.
Human F. hepatica infection is determined by the presence of the intermediate snail hosts, domestic herbivorous animals, climatic conditions, and the dietary habits of man. [32] Sheep, goats and cattle are considered the predominant animal reservoirs. While other animals can be infected, they are usually not very important for human disease ...
A diagnosis may be made by finding yellow-brown eggs in the stool. They are indistinguishable from the eggs of Fascioloides magna, although the eggs of F. magna are very rarely passed in sheep, goats, or cattle. If a patient has eaten infected liver, and the eggs pass through the body and out via the faeces, a false positive result to the test ...
Four species infect humans: B. abortus, B. canis, B. melitensis, and B. suis. B. abortus is less virulent than B. melitensis and is primarily a disease of cattle. B. canis affects dogs. B. melitensis is the most virulent and invasive species; it usually infects goats and occasionally sheep. B. suis is of intermediate virulence and chiefly ...
Eimeria is a genus of apicomplexan parasites that includes various species capable of causing the disease coccidiosis in animals such as cattle, poultry and smaller ruminants including sheep and goats. [2]
