Viruses, which are much smaller than bacteria, cause diseases such as measles, mumps, rubella (German measles), chicken pox and HIV.
Fungal infections include ringworm and athlete’s foot and parasites include head lice and scabies.
Not all infectious diseases are contagious.
What microorganism causes diseases such as gonorrhea and syphilis?
Bacteria that are part of normal internal ecosystems, also known as bacterial flora, are called Endogenous Bacteria. A significant amount of prominent diseases are induced by exogenous bacteria such as gonorrhea, meningitis, tetanus, and syphilis.
What causes diseases such as ringworm and athlete’s foot?
Jock itch, athlete’s foot, and ringworm are all types of fungal skin infections known collectively as tinea. They’re caused by fungi called dermatophytes that live on skin, hair, and nails and thrive in warm, moist areas.
What are disease causing organisms?
Most microbes belong to four major groups: bacteria, viruses, protozoa or fungi. Disease-causing microbes can also be called pathogens, germs or bugs and are responsible for causing infectious diseases.
How do pathogens differ from Nonpathogens?
Nonpathogenic organisms are those that do not cause disease, harm or death to another organism and is usually used to describe bacteria. Some of these same nonpathogenic microorganisms have the potential of causing disease, or being pathogenic if they enter the body, multiply and cause symptoms of infection.
