The liver hairworm Capillaria hepatica is found primarily in rodents and lagomorphs; infections of dogs are rare. Infection occurs by eating the liver of a rodent. Clinically, symptoms such as abdominal discomfort and hepatomegalia occur as the larvae migrate through the liver and lay eggs. A definite diagnosis can only be made by liver biopsy ...
It was first identified and isolated from dog feces, though sheep and cats may also be important reservoirs of the bacterium. [2] Its type strain is NCTC 12739 T. It colonises the lower bowel, but is also present in cases of hepatitis. [3] Besides infecting dogs, this bacterium is known to cause infections in immunocompromised humans. [4] [5]
The animal reservoir of the virus maintains a suitable virus level in the blood to allow the infection of a vector mosquito. A bridge-vector mosquito such as Aedes albopictus , which can survive in an urban area and spread to rural, semi-rural, and forest areas could carry the virus to a sylvatic environment.
Giardiasis* is an intestinal infection in dogs caused by the protozoa Giardia lamblia. The most common symptom is diarrhea. The zoonotic potential of giardiasis is controversial. [25] [26] Coccidiosis can be caused by a variety of coccidian organisms in dogs, most commonly Isospora. There are usually no symptoms, but diarrhea and weight loss ...
Chain of infection; the chain of events that lead to infection. There is a general chain of events that applies to infections, sometimes called the chain of infection [14] or transmission chain. The chain of events involves several steps – which include the infectious agent, reservoir, entering a susceptible host, exit and transmission to new ...
Especially in the New World, infection is a zoonotic disease, involving different canine species, including domestic dog and the two fox species, Lycalopex vetulus and Cerdocyon thous. In the Mediterranean region domestic dogs and the three fox species Vulpes vulpes , V. corsac and V. zerda are common reservoir hosts.

Cows are natural reservoirs of African trypanosomiasis. In infectious disease ecology and epidemiology, a natural reservoir, also known as a disease reservoir or a reservoir of infection, is the population of organisms or the specific environment in which an infectious pathogen naturally lives and reproduces, or upon which the pathogen primarily depends for its survival.
