Microbiology
| Question | Answer |
|---|---|
| What are Microorganisms | a collection of organisms that share the characteristic of being visible only with a microscope. |
| What is Microbiology | the study of microorganisms |
| Is a Protozoa - unicellular or multicellular? | unicellular (one) |
| What is the name of the microorganism that causes infectious diseases? | Pathogens |
| Define Disease | it is any disruption of normal body (normal flora) functioning. |
| What color(s) do Gram Positive (+) Bacteria appear as? | purple or blue |
| What color(s) do Gram Negative (-) Bacteria appear as? | pink or red |
| Define Gram Stain | shows us the SHAPE of the BACTERIA and their GRAM REACTIONS. (they are either a gram positive or gram negative based on the chemicals in their cell walls. |
| What is the first step in identifying the pathogen that is causing a particular infection? | doing the GRAM STAIN |
| Define Taxonomy | it is the science of classification. Taxonomy displays the unity and diversity among living things, including microorganisms. |
| Microorganisms is also A.K.A.? | microbes |
| What is the name of microorganisms that cause INFECTIOUS DISEASES? | the are called PATHOGENS |
| Pathogens may also be called? | parasites |
| What are parasites? | Parasites live on another living organism called a host and cause harm to the host. |
| Define Classification | Classification highlights characteristics that are COMMON among certain groups while PROVIDING ORDER to the variety of living things. |
| Define Bacteria | bacteria are VERY SIMPLE SINGLE-CELLED (unicellular) organisms. |
| Define Viruses | Viruses are NOT CELLS, they are even smaller than and simpler in structure than the bacteria. |
| Why are all viruses parasites? | because they can reproduce only within the living cells of a host. |
| What are common human viral diseases? | Influenza, Chicken Pox, and the Common Cold. |
| What are some human bacterial diseases? | strep throat, pneumonia, and meningitis. |
| Define Protozoa | Protozoa are single-celled (unicellular) animals such as amoebas. |
| What diseases do human protozoan parasites cause? | malaria, dysentery, and pneumocystis pneumonia (common in AIDS patients. |
| Define FUNGI | Fungi may be unicellular or multicellular |
| What are some familiar fungi? | molds and mushrooms |
| What do fungi do? | they decompose organic matter in the soil and fresh water help recycle nutrients. |
| Where are the protozoa habitat? | They are free-living in fresh or salt water. |
| What do the protozoa do> | They consume bacteria, fungi, and one another. |
| What is the natural habitat(s) of bacteria? | Natural Habitat include: fresh water, salt water, soil and other living organisms. |
| What are some types of fungal diseases? | yeast infections, ringworm, and more serious diseases as a type of meningitis. |
| define worms | they are multicellular animals. Most are fee-living and non-pathogenic. |
| Where is bacteria found? | They are found everywhere. |
| what are some worm infestations of people? | they include trichinosis, hookworm disease, and tapeworms. |
| define Arthropods | Arthropods are multicellular animals such as lobsters, shrimp, the insects, ticks, mosquitoes, fleas and mites. |
| what is a vector | a vector is spreads pathogens from host to host (examples are mosquitoes, ticks and fleas) |
| what does the word "Arthropods" mean | the name means "jointed legs" |
| Define BINOMIAL NOMENCLATURE | referring to bacteria and all other living things using two names (binomial nomenclature) |
| How is a Binomial Nomenclature written? | example: Staphylococcus aureus. Binomial would be the "genus" name, placed first with a capital letter and is the largest category (ex: Staphylococcus) and the Nomenclature would be the "species" name, is second, and NOT capitalized (ex: aureus) |
| define Normal Flora | is a natural population of microorganisms living on or within us. |
