| Question | Answer |
|---|---|
| Bacilli (Bacillus)- | Bacteria that have a rod shape. |
| Cocci (Coccus)- | Bacteria that have a round shape. |
| Colony- | A mass of bacteria growing on a solid culture medium that have arisen from the multiplication of a single bacterium. |
| Contagious- | Capable of being transmitted directly or indirectly from one person to another. |
| Culture- | The propagation of a mass of microorganisms in a laboratory culture medium. |
| Culture Medium- | A mixture of nutrients on which microorganisms are grown in the laboratory. |
| False negative- | A test result denoting that a condition is absent when it is actually positive. |
| False Positive- | A result denoting that a condition is present when it is actually absent. |
| Fastidious- | Extremely delicate, difficult to culture, and involving specialized growth requirements. |
| Immunization- | The process of becoming protected from a disease through vaccination. |
| Incubate- | In microbiology, the act of placing a culture in a chamber (incubator) that provides optimal growth requirements for the multiplication of the organisms,such as the proper temperature, humidity, and darkness. |
| Incubation Period- | The interval of time between the invasion by a pathogenic microorganism and the appearance of first symptoms of the disease. |
| Infectious Disease- | A disease caused by a pathogen that produces harmful effects on its host. |
| Inoculate- | To introduce microorganisms into a culture medium for growth and multiplication. |
| M | The scientific study of microorganisms and their activities. |
| Mucous Membrane- | A membrane lining body passages or cavities that open to the outside. |
| Normal Flora- | Harmless, non-pathogenic microorganisms that normally reside in many parts of the body but do not cause disease. |
| Resistance- | The natural ability of an organism to remain unaffected by harmful substances in its environment. |
| Sequela- | A morbid (secondary)condition occurring as a result of a less serious primary infection. |
| Smear- | Material spread on a slide for microscope examination. |
| Specimen- | A small sample or part taken from the body to show the nature of a whole. |
| Spirilla (Spirillum)- | Bacteria that have a spiral or curved shape. |
| Streaking- | In microbiology,the process of inoculating a culture to provide for the growth of colonies on the surface of a solid medium. Streaking is accomplished by skimming a wire inoculating a loop that contains the specimen across the surface of the medium. |
| Streptolysin- | an exotoxin produced by beta-hemolytic streptococci, which completely hemolyzes red blood cells. |
| Susceptible- | Easily affected, lacking resistance. |
