| Infectious disease (agent) need a reservoir to grow, live and multiply. What are three common reservoirs for this to happen? | Humans, animals and the environment |
| Describe the cell's capsule. | It protects the cell from being destroyed. Just like our white blood cells destroy bacteria in our bodies. |
| Describe acid fast red stain and nonacid-fast blue stain | Bacteria retains 1st red stain (fast) Bacteria loose 1st stain and pickups the 2nd blue stain (non-fast). |
| How is Hepatitis B, C, D & E transmitted? | Body fluids |
| Which is smaller, bacteria or viruses? | Viruses |
| Can Tuberculosis survive for years in a dry state ? | Yes |
| Name 3 non-bacterial organisms. | Viruses, fungi and protozoa |
| In the Ziehl-Neilson Stain, which bacteria retains the primary stain? Acid fast-Red or Non-acid fast- blue? | Acid fast - Red |
| Why do hospitals use Ultraviolet light? | Ultraviolet light can kill the spore of gram-positive Bacilli |
| A virus has no way to move, they rely on air, water, insects, humans and or _______ to carry it from host to host. | animals. |
| What color are Gram Positive bacteria? | Purple |
| Describe the cell's flagella. | Tails that gives the cell the ability to move through liquids. |
| What is gram-positive? | It's bacteria that keeps the stain (purple) color, when a decolorizing agent is applied. |
| Describe the Ziehl-Neilson stain | It identifies acid-fast bacteria (bacteria that stains fast/ easily). |
| What are examples of "Airborne" as it relates to "Mode of Transmission? | Droplets or dust remaining in the air. |
| It's important for an infectious disease to have a reservoir, mode of transmission and susceptible host. Name 4 modes of transmission. | 1. Direct contact 2. Common vehicle 3. Airborne 4. Vector borne. |
| Herpes simplex is a Fungi, Protozoa or virus? | Virus |
| To cause infections, six things must happen. Virulence (ability to grow) Invasiveness (ability to enter) Pathogenicity (ability to cause disease) name final 3. | Ability (ability to resist antibiotics) Infection dose (amount required to cause disease) Viability (ability to survive outside host) |
| What are the components of a typical cell? | Cell wall, cell membrane, cytoplasm, capsule, flagella and nucleus. |
| Are viruses smaller or larger than bacteria? | smaller |
| True or false. The bacteria nucleus has a nuclear membrane enclosing the DNA. | False. The bacteria nucleus does not have a membrane that encloses the DNA. It floats without restrictions. |
| What measurement is used to measure Bacteria and cells? | Microns |
| What does a virus do once it enters a plant or animal? | Reproduce, destroys the cell and move on to another cell. |
| True or false. Plants and animals chromosomes are enclosed in a nuclear membrane. | True. |
| What are the two groups Gram Stain divides bacteria? | Gram-positive and gram-negative |
| What color is Acid fast bacteria and non-acid fast? | Red; Blue |
| Who was Ziehl-Neilson? | Fraz Ziehl (1854-1898) a bacteriologist and Friedrich Neelson (1859-1926) a pathologist. |
| How many microns is bacteria? | 1 or 2 |
| Reservoir+Agent+Mode of Transmission+Susceptible host= | Chain of infection |
| What 5 things that can make a person or animal vulnerabl to disease? | Age Injury Weak immune system History of disease (diabetes) Under nourished |
| How long can Herpes virus survive on plastic? Cotton gauze? | 8 hours, 72 hours |
| What color are Gram Negative bacteria? | Pink |
| How can cells protect themselves? | They form a spore: a thick layer around the nucleus. Spores are hard to kill and are a direct problem for Sterile Processing. |
| What are the two common stains used to identify bacterial? | Gram stain and Ziehl-Neelson stain a.k.a Acid Fast |
| What are the 3 temperature requirements for bacteria? | Psychrophiles Mesophiles Thermophiles |
| When talking about "Mode of Transmission" What are examples of "Common vehicle"? | Food, blood and water |
| Why would ultraviolet lights be used in the Operating Room; in regards to bacteria? | Ultraviolet light can disinfect air and purify the environment. |
| Some bacteria require oxygen (aerobic). Some bacteria does not require oxygen (.....). | Anaerobic |
| True or False. Gram stain helps identify infectious disease such as tuberculosis and leprosy. | False. Acid fast testing helps identify tuberculosis and leprosy. |
| What are the six links in the "Chain of Infection"? | 1. Causative agent 2. Reservoir of the agent 3. Portal of exit of the agent from the reservoir 4. Mode of Transmission of the agent 5. Portal of entry into the host 6. Susceptible host |
| Name 4 characteristics of microorganisms | cell structure, DNA, means of reproduction and size |
| Between Gram Positive and Gram Negative bacteria, which has a thick cell wall and which has a thin cell wall? | Gram Positive: thick wall Gram Negative: thin wall |
| The Gram Stain process includes 1. the primary stain 2. decolorize 3. _________ | The counter or secondary stain. |
| True or false. Mesophiles like to grow at body temperature. | True |
| How can cells protect themselves in a hostile environment. | Creating a thick coat around the nucleus; a spore. |
| What is gram-negative? | Bacteria with an outer membrane. Will not retain 1st stain. Will pick up the counterstain (safranin). Looks pink. |
| True of False: Microorganisms that can cause disease to humans have a pH range the same as human blood. 7-7.8 | True |
| What are the common ways to identify and classify microorganisms? | By shape, color change and need for oxygen. |
| There are 5 categories of Microorganisms according to Steris University. What are they? | Bacteria, virus, fungi, protozoa and prions |
| Describe a cell wall. | Keeps cell structure because it's tough. |
| Describe the cell's nucleus. | It controls the cells. It's where the DNA lives. |
| What are examples of Direct contact in the case of Mode of Transmission? | Kissing and or touching |
| What two staining processes are important to SPD? | Gram stain and the Ziehl-Neilson stain |
| Describe the cell's membrane. | Semi-permeable and allows gasses and liquids to pass in and out of cell. It's just under the cell wall. |
| How are microorganisms helpful in food? | They are part of the cheese making process. |
| In Gram Stain, which bacteria (positive or negative) retains the primary stain and which looses the primary color? | Gram Positive bacteria retains the primary stain. Gram Negative bacteria looses it's color during the de-colorization. It takes on the counter stain. |
