| Microbiology is | the study of organisms too small to be seen without magnification |
| Microorganisms include: | bacteria, viruses, fungi, protozoa, helminths (worms), and algae |
| Branches of study within Microbiology | Immunology,Public health microbiology and epidemiology,Genetic engineering and recombinant DNA technology, Food, dairy and aquatic microbiology,Biotechnology, |
| Microbes are Involved in | Nutrient production and energy flow, Decomposition,Biotechnology( production of foods, drugs and vaccines), Genetic engineering,Infectious disease ,Bioremediation |
| How many different microbes cause diseases? | Nearly 2,000 different microbes cause diseases. |
| How many new infections are there per year worldwide? | 10 B new infections/year worldwide |
| How many deaths are there each year worldwide due to infectious diseases? | 13 M deaths from infections/year worldwide |
| procaryotes are | microscopic, unicellular organisms, lack nuclei and membrane-bound organelles |
| eucaryotes are | unicellular (microscopic) and multicellular, nucleus and membrane-bound organelles |
| heat resistant forms of some microbes | endospores |
| requires the elimination of all life forms including endospores and viruses | Sterility |
| aseptic techniques reducing microbes in medical settings to prevent infections | disinfection of hands using chemicals prior to surgery, use of heat for sterilization |
| Demonstrated what is now known as Germ Theory of Disease ,Developed a rabies vaccine | Louis Pasteur (1822-1895) |
| True bacteria have | peptidoglycan |
| Immunology | The study of the system of body defenses that protect against infection. |
| Pathogen | Any agent that causes disease. |
| Parasite | An organism that lives on or within another organism (the host), from which it obtains nutrients and enjoys protection. The parasite produces some degree of harm in the host. |
| Host | Organism in which smaller organisms or viruses live, feed and reproduce. |
| Sterile | Any process that completely removes or destroys all viable microorganisms, including viruses, from an object or habitat. |
| Methods of handling microbial cultures, patient specimens, and other sources of microbes in a way that prevents infection of the handler and others who may be exposed. | Aseptic techniques |
| Germ Theory of Disease | A theory first orginating in the 1800s which proposed that microorganisms can be the cause of diseases. |
