The larvae mature into adults within the small intestine of a cat, dog, or fox, where mating and egg-laying occurs. [9] [12] [16] [21] Eggs are passed in the feces and only become infective after three weeks outside of a host. [27] During this incubation period, molting from first to second (and possibly third) stage larva takes place within ...
Animals also present with similar clinical features when compared to humans. Clinical signs can appear in 5–15 days in dogs. The incubation period can be prolonged in cats. Leptospirosis can cause abortions after 2–12 weeks in cattle, and 1–4 weeks of infection in pigs. The illness tends to be milder in reservoir hosts.
FVR has a two- to five-day incubation period. [3] The virus is shed for one to three weeks postinfection. [4] Latently infected cats (carriers) will shed FHV-1 intermittently for life, with the virus persisting within the trigeminal ganglion. Stress and use of corticosteroids precipitate shedding. Most disinfectants, antiseptics and detergents ...
Feline calicivirus (FCV) is a virus of the family Caliciviridae that causes disease in cats. It is one of the two important viral causes of respiratory infection in cats, the other being Felid alphaherpesvirus 1. FCV can be isolated from about 50% of cats with upper respiratory infections. [2]
The 2023-2024 norovirus season is well underway in the United States. Cases of the highly contagious stomach bug, which causes diarrhea and vomiting, are climbing steadily across the country.
The terms "intrinsic incubation period" and "extrinsic incubation period" are used in vector-borne diseases. The intrinsic incubation period is the time taken by an organism to complete its development in the definitive host. The extrinsic incubation period is the time taken by an organism to develop in the intermediate host. [citation needed]

In a large group of cats, n, the epidemiological risk of mutation (E) is higher and expressed theoretically as: E = n 2 −n. A house hosting 2 cats therefore has risk of mutation E = 2. When 4 kittens (6 cats in total) are born into this house, the risk increases from 2 to 30 (6 2 −6). Overcrowding increases the risk of mutation and ...
