L. ivanovii is a pathogen of mammals, specifically ruminants, and rarely causes listeriosis in humans. [7]
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 ...
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]
English: In some diseases, as depicted in this diagram, the latent period is longer than the incubation period. After the latency period (but prior to the infection period) the infected person can transmit the disease without signs of any symptoms. Such infection is called subclinical infection.
Travelers' diarrhea (TD) is a stomach and intestinal infection. TD is defined as the passage of unformed stool (one or more by some definitions, three or more by others) while traveling.

Once the cat is infected, after an incubation period of 2 to 3 days, [6] the virus can be found in the respiratory tissues, attached to the type II pneumocytes and alveolar macrophages, [4] as well as the intestinal tissues. In some cases where the virus has been found in the brain and other systems in the body. [13]
Here's what you need to know if you think you have the norovirus, commonly called the "stomach flu" or "stomach bug," and how to prevent spreading the sickness. Keep stomach bugs at bay with these ...
