Infection usually occurs by eating undercooked contaminated meat, exposure from infected cat feces, or mother-to-child transmission during pregnancy. Soil Borne Disease Control. The fungus lives in the environment, particularly in moist soil and in decomposing matter such as wood and leaves.

Infectious and Parasitic Diseases. from mining and smelting activities, foundries etc.) Contaminants in soil accumulate in plant tissue, to be passed to grazing animals, birds, and to the humans that eat them. Oil and petroleum products have many volatile compounds that are emitted into the soil as gases whenever oil spills occur. Soil is a considerable biologic sink, and certainly some organisms found in it are pathogenic in humans. Most pesticides and fertilizers contain benzene, chromium and other chemicals, which are carcinogens (chemicals that cause cancer). Soil pH and nutrient levels will also contribute to pathogen infection. How is toxoplasmosis transmitted? Soil is also responsible for maintaining natural and artificial vegetation. Most people infected with B. pseudomallei experience no symptoms, but those who do experience symptoms have signs and symptoms that range from mild, such as fever, skin changes, pneumonia, and abscesses, to severe with inflammation of the brain, inflammation of the joints, and … Read on to find out which diseases humans can get from cats.
