Which of the following is a known reservoir of Listeriosis?

Listeriosis is caused by the bacterium Listeria monocytogenes, which is commonly found in various environments and species. The correct choice highlights a broad range of known reservoirs that can harbor this pathogen. Goats, cattle, humans, fowl, as well as environmental sources like soil, water, and sewage, provide ample opportunity for the bacteria to exist and be transmitted.

Animals such as cattle and goats can carry Listeria without showing symptoms, while humans can also become infected through the consumption of contaminated food or water, including unpasteurized dairy products and ready-to-eat meats. The presence of Listeria in soil and water further emphasizes the bacterium's ubiquity in diverse environmental reservoirs. This multifaceted presence supports the understanding that various living organisms and natural resources contribute to the lifecycle and spread of Listeriosis.

The other options are too limited or do not accurately encapsulate the range of Listeria reservoirs, which are extensive and include both animal and environmental sources.
