 Infections DIseases | These are defined as an invasion & multiplication of microorganisms in the body tissue that results in cellular damage. |
| TB / Malaria | What are the two main diseases that cause death worldwide? |
| Virus | These are the smallest human pathogens ranging in size from 20-300nm. They are incapable of independent metabolism or reproduction and thus are obligate intracellylar parasites. |
| True | Viruses are non living entities that have DNA or RNA (but never have both together). T/F |
| RNA VIrus | These viruses are the most common viruses on this earth. They are called retroviruses. Name this type of virus (RNA or DNA). |
| Reverse Transcriptase / Integrase | There have to be 2 enzymes present with the RNA. Name them. |
| DNA Viruses | These viruses go right straight into the nucleas. Name them. (RNA or DNA). |
| Epstein Bar Virus | This virus most famously causes mono. THis is a DNA virus. Name it. |
| Hepatitis B | This is the only virus that is a DNA virus of the hepatitis family. |
| DNA | CMV, EBV, HBV and Herpes (Varicella) are DNA or RNA viruses? |
| Chronic Infections | Viruses that don't get eliminated from the body (Hep B and Hep C) go anywhere from 10% to 80% chronic. They are diseases we cannot get rid of. Are these chronic or acute infections? |
| 3-7 Days | How many days does it take the T cells to breakdown a virus (who is NOT an immunocompromised individual). |
| Virons | These are "daughter viruses." They become replicated and then invade. This is why influenza is so bad at the age extremes because bacterial infections are bad news. Bacteria is an opportunistic organism after a virus. Bacteria loves dead cells. It can go down into your lungs and you now have pneumonia. Name this term. |
| RhotaVirus | This virus is the number one cause of viral diarrhea in the world. Here in the U.S, it is just a pain to the parents but usually does not kill. |
| Rhinovirus | This is the most common cause / virus of the common cold. Name it. |
| Human Papilloma Virus | These get inside the cells and cause the cells to release chemicals that cause proliferation (warts to venerial warts). |
| Bacteria | These are living organisms unlike viruses. They always have a cell wall, but it does not have a plasma membrane. They also do not have a nucleus. Their DNA is all over the cell. Name this organism. |
| Wall | Most of our antibodies work on the cell_________. |
| E Coli | This is the number one cause of UTI in the United States. Name this gram negative bacteria. |
| Streptococcus Pneumonia | This is a slime layer is hard for our WBC to phagocytize it. It is a common slime layer. Name it. |
| Dead | Bacteria is attracted to________tissue. Therefore, we have a lot on our skin. |
