|---|---|
| Bacteria that have a rod shape. | BACILLI (SING. BACILLUS) |
| Bacteria that have a round shape. | COCCI (SING. COCCUS) |
| A mass of bacteria growing on a solid culture medium that have arisen from the multiplication of a single bacterium. | COLONY |
| Capable of being transmitted directly or indirectly from one person to another. | CONTAGIOUS |
| The propagation of a mass of microorganisms in a laboratory culture medium. | CULTURE |
| A mixture of nutrients on which microorganisms are grown in the laboratory. | CULTURE MEDIUM |
| A test result denoting that a condition is absent when it is actually present. | FALSE NEGATIVE |
| A test result denoting that a condition is present when it is actually absent. | FALSE POSITIVE |
| Extremely delicate, difficult to culture, and involving specialized growth requirements. | FASTIDIOUS |
| The process of becoming protected from a disease through vaccination. | IMMUNIZATION |
| 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. | INCUBATE |
| The interval of time between the invasion by a pathogenic microorganism and the appearance of first symptons of the disease. | INCUBATION PERIOD |
| A disease caused by a pathogen that produces harmful effects on its host. | INFECTIOUS DISEASE |
| To introduce microorganisms into a culture medium for growth and multiplication. | INOCULATE |
| The scientific study of microorganisms and their activities. | MICROBIOLOGY |
| A membrane lining body passages or cavities that open to the outside. | MUCOUS MEMBRANE |
| Harmless, nonpathogenic microorganisms that normally reside in many parts of the body but do not cause disease. | NORMAL FLORA |
| The natural ability of an organism to remain unaffected by harmful substances in its environment. | RESISTANCE |
| A morbid (secondary) condition occurring as a result of a less serious primary infection. | SEQUELA |
| Material spread on a slide for microscope examination. | SMEAR |
| A small sample or part taken from the body to show the nature of the whole. | SPECIMEN |
| Bacteria that have a spiral or curved shape. | SPIRILLA (SING. SPIRILLUM) |
| 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 loop that contains the specimen across the surface of the medium, using | STREAKING |
| An exotoxin produced by beta-hemolytic streptococci, which completely hemolyzes red blood cells. | STREPTOLYSIN |
| Easily affected, lacking resistance. | SUSCEPTIBLE |
