Not all strains of a bacteria species are virulent; there are some strains of Corynebacterium diphtheriae that do not produce diphtheria toxin and are considered nonvirulent and nontoxigenic. Additional classifications used to describe toxins include enterotoxin , neurotoxin , leukocidin or hemolysin which indicate where in the host's body the ...
Food microbiology is the study of the microorganisms that inhabit, create, or contaminate food.This includes the study of microorganisms causing food spoilage; pathogens that may cause disease (especially if food is improperly cooked or stored); microbes used to produce fermented foods such as cheese, yogurt, bread, beer, and wine; and microbes with other useful roles, such as producing ...
Foodborne illness (also known as foodborne disease and food poisoning) [1] is any illness resulting from the contamination of food by pathogenic bacteria, viruses, or parasites, [2] as well as prions (the agents of mad cow disease), and toxins such as aflatoxins in peanuts, poisonous mushrooms, and various species of beans that have not been boiled for at least 10 minutes.
A food contaminant is a harmful chemical or microorganism present in food, which can cause illness to the consumer. Contaminated food . The impact of chemical contaminants on consumer health and well-being is often apparent only after many years of processing and prolonged exposure at low levels (e.g., cancer). Unlike food-borne pathogens ...
Some bacteria are responsible for the spoilage of food. When bacteria breaks down the food, acids and other waste products are generated in the process. [2] While the bacteria itself may or may not be harmful, the waste products may be unpleasant to taste or may even be harmful to one's health. [3]
Microbes can make nutrients and minerals in the soil available to plants, produce hormones that spur growth, stimulate the plant immune system and trigger or dampen stress responses. In general a more diverse set of soil microbes results in fewer plant diseases and higher yield.
It is toxic to horses, prevents native plants from growing (decreasing biodiversity and degrading natural ecosystems), and is a physical barrier to the migration of indigenous animals. The increasing globalization of agriculture has resulted in the accidental transport of pests, weeds, and diseases to novel ranges.
Plants live in association with diverse microbial consortia. These microbes, referred to as the plant's microbiota, live both inside (the endosphere) and outside (the episphere) of plant tissues, and play important roles in the ecology and physiology of plants. [5] "The core plant microbiome is thought to comprise keystone microbial taxa that ...
