The term used to describe a disease-causing microorganism is
These “bad-news” microbes are called disease-causing microbes and can make humans, animals and plants sick by causing infection and disease. Most microbes belong to four major groups: bacteria, viruses, protozoa or fungi.(To find out more, see the “Bacteria/Viruses/Protozoa” fact sheets).Disease-causing microbes can also be called pathogens, germs or bugs and are responsible for causing infectious diseases.They can also contribute to chronic diseases and conditions, and are now being linked with coronary artery disease, diabetes, and certain types of cancer, multiple sclerosis and chronic lung disease.ost microbes belong to four major groups: bacteria, viruses, protozoa or fungi. (To find out more, see the “Bacteria/Viruses/Protozoa” fact sheets). Disease-causing microbes can also be called pathogens, germs or bugs and are responsible for causing infectious diseases. The ability of bacteria to cause disease is described in terms of the number of infecting bacteria, the route of entry into the body, the effects of host defense mechanisms, and intrinsic characteristics of the bacteria called virulence factors.irulence is, by MeSH definition, the degree of pathogenicity within a group or species of parasites as indicated by case fatality rates and/or the ability of the organism to invade the tissues of the host. a disease causing microorganism is called a pathogen. origin-pathos=suffering disease (in greek). all pathogens are microorganisms but all microorganisms are not pathogens.or baceria, antibiotics. These are chemicals that directly attack the bacteria. The problem we have is that we've been challenging them for the last 70-odd years, and natural … selection has produced highly-resistance strains such as Methicillen Resitant Staph. Aueroeus. Best Answer: Answer is A-Pathogens. They can be bacteria, fungus etc etc. Your other three answers could be examples for pathogens, though without the species name you cannot identify any of those micro organisms as a disease causing organism.Since there are cocci and bacillus bacteria that are good freindly bacteria in our gut and are essential for our digestive system ...our other three answers could be examples for pathogens, though without the species name you cannot identify any of those micro organisms as a disease causing organism. Micro-organisms. Micro-organisms Micro-organisms (or microbes) are literally microscopic organisms, which can only be seen properly with the aid of a microscope.These include bacteria, microscopic fungi (moulds) and protoctists.icro-organisms. Micro-organisms Micro-organisms (or microbes) are literally microscopic organisms, which can only be seen properly with the aid of a microscope. The pathogenicity of an organism-its ability to cause disease-is determined by its virulence factors. The noun virulence derives from the adjective virulent. Virulent can describe either disease severity or a pathogen's infectivity.irulence is, by MeSH definition, the degree of pathogenicity within a group or species of parasites as indicated by case fatality rates and/or the ability of the organism to invade the tissues of the host. Protoctists: malaria, amoebic dysentery. Fungi: athlete's foot, ringworm. These disease-causing organisms are called pathogens and we often refer to them in everyday, non-scientific terms as germs or bugs. Each disease has a specific pathogen, i.e. different diseases are caused by different kinds of germ.icro-organisms. Micro-organisms Micro-organisms (or microbes) are literally microscopic organisms, which can only be seen properly with the aid of a microscope. Harmful bacteria that cause bacterial infections and disease are called pathogenic bacteria. Bacterial diseases occur when pathogenic bacteria get into the body and begin to reproduce and crowd out healthy bacteria, or to grow in tissues that are normally sterile.acteria are a type of microorganism, which are tiny forms of life that can only be seen with a microscope. Other types of microorganisms include viruses, some fungi, and some parasites. Millions of bacteria normally live on the skin, in the intestines, and on the genitalia. Virulence is, by MeSH definition, the degree of pathogenicity within a group or species of parasites as indicated by case fatality rates and/or the ability of the organism to invade the tissues of the host.irulence is, by MeSH definition, the degree of pathogenicity within a group or species of parasites as indicated by case fatality rates and/or the ability of the organism to invade the tissues of the host. In some cases, antibiotics are able to kill pathogenic microbes without harming human cells. Because bacterial cells are prokaryotic and rely on different metabolic processes, some antimicrobials can target these cells without harming human eukaryotic cells. disease breaks out among sheep in California. Koch's postulates. Koch's postulates rely on very specific factors and steps conducted to prove that a particular organism is the cause of a disease: 1.
