Individual microbes can be observed only with the use of various types of microscopes: microbes: nonliving entities as well as certain living entities. Microbes that cause disease are known as pathogens. Those that do not cause disease are called nonpathogens. Microbes that live on and in the human body are referred to as our indigenous microflora. Opportunistic pathogens do not cause disease under ordinary conditions, but have the potential to cause disease should the opportunity present itself. A rare cause of infections: intoxications (which result from the ingestion of toxins) Bacteria anthrax, botulism, cholera, diarrhea, diphtheria, ear and eye infections.
