A | B |
Morbillivirus (measles virus) is identified by presentation which includes | Sore throat, dry cough, fever, KOPLIK'S SPOTS |
Morbillivirus (measles virus) is virulent because_________ | SYNCYTIUM formation |
Human immunodeficiency virus 1 and 2 (HIV-1, HIV-2) is identified by | Two-stage serological testing |
HIV presents with vague symptoms which quickly dissipate followed by | 2 to 15 year asymptomatic phase, followed by the appearance of AIDS-defining illnesses |
HIV is virulent because of _________ and is treted with antivirals and barrier protection (condoms) | REVERSE TRANSCIPTASE and RAPID MUTATION |
This organism is detected by serological testing of the ANTIPOLIOVIRUS ANTIBODIES and is virulent because it is a | NAKED VIRUS (more resistant) |
Poliovirus causes polio which symptoms are | Fever, stiffness in the neck and back (5% of infected people) or PERMANENT PARALYSIS (less than 1% of infected people). Most people infected actually show no symptoms |
Both polio and measles can be prevented with ______ and relieving ______ | vaccines, symptoms |
Adsorption | when the virus attaches to the host |
Penetration | virus enters the cell membrane of the host cell |
Uncoating | release viral capsid and the nucleaic acid (RNA) |
Synthesis | host cell makes basic components for the new cell (RNA, CAPSOMERS and SPIKES) |
Assembly | virus components come together to make whole viruses |
Release | virus leaves the host cell ready to infect another cell |
three impacts viruses can have on host organisms | permanently alter genetic material, development of tumors, induce damage to the cells and cause them to change their microscopic appearance, can become disoriented, undergo gross changes in shape or size or develop intercellular changes. |
Yeast cells (eukaryotic) are very ______ compared to bacteria (Prokaryotic) and virus are even ______ than bacteria | Large, smaller |
Some viruses covering is _____ and others covering is ______ | "naked" and “enveloped.” |
ruses contain ______ | EITHER DNA or RNA BUT NOT but not BOTH at the same time |
capsid | protective outer shell of virus |
lambda bacteriophages | viruses that target bacteria |
Hsv1 lesions occur on ______ and Hsv2 lesions on ______ | oropharynyx, genitalia |
This virus causes HSV 1 and HSV 2 and is prevented by using barriers | Herpes simplex virus 1 and 2 (HSV-1 and HSV-2) |
Varicella-zoster virus (VZV) causes ______ and ______ is prevented with vaccine and treated with antivirals | Chicken pox (primary numerous lesions, crust and drop off) and shingles (latent, painful rash) |
Epstein-Barr virus (EBV) | virus causes mononucleosis disease, presents with sore throat, fever SWOLLEN LYMPH NODES and is identified by blood count, risk of CANCER |
Hepatitis B virus (HBV) | causes hepatitis B symptom is JAUNDICE (yellowing of skin) and increases risk of LIVER CANCER |
Control/prevention of Hepatitis B virus is | passive immunization |
Human papillomavirus (HPV) | is persistent, causes warts/veruca, is identified by appearance in is prevented by vaccine and barriers, treated with wart removal |
Influenza virus is treated with antiviral meds and primary infection/disease is | death of cilliated cells in airway, cough and fever |
What is “prion” short for? | proteinaceous infectious diseases. |
are prions made up of DNA, RNA, or protein? | protein |
Prions cause what type of disease | trandsmisable spongiform diseases such as encephalopathies (mad cow) and Cruthcfileds-Jacobs in humans |
How is a prion formed? | alteration in structure of the normal host protein (PRPC) in mamillian brains which then creates a chain reaction of alteration of other brain cell protein to PRPC |
What are the symptoms of CJD | altered behavior, dementia, memory loss, impaired senses, delirium, and premature senility;Uncontroable muscle contractions continue until death which usually occurs within 1 year of diagnosis |
prevention/ treatment of CJD | avoid contact with infected tissue, there is no known treatment for CJD. |
