Lab final Flashcards
What does an indirect fluorescent antibody assay look for
viral antibodies in patient serum
what does an indirect fluorescent antibody assay need
- Patient serum
- Slide with infected cells with a specific virus
- Antibody against your patient antibodies
IFA is a __assay meaning you want to know whether antibodies are high or low concentration (active or no infection)
titration assay
is IFA quantitative or qualitative
quantitative
what is electron microscopy and what looking for
technique to take high resolution images to look for viral particles
does electron microscopy take advantage of short or long wave lengths
short
what is transmission electron microscopy used for
Look at thin pieces of tissue or segments in flat plane
what is scanning electron microscopy used for
provide depth to prepared samples
which is transmission electron microscopy vs scanning
top- transmission
Bottom: scanning
what is odds ratio equation
OR= odds of event in the exposed group/ odds of event in non exposed group
odds ratios are typically derived from __studies
retrospective
What is relative risk equation
probability of the event of the exposed group/ probability of event in non-exposed group
Or
(Positive/positive +negative of exposed)/ (positive non exposed)/ (positive non-exposed and negative)
relative risk is calculated based on __studies
prospective studies
what is BLAST
online program that allows you to search DNA or protein sequences that have been published or compare two DNA sequences of unknown
what does FeLV and FIV SNAP test detect
The FIV portion detects viral antibodies, while the FeLV portion detects viral antigen
what information is provided by disease mapping
- Regional distribution of infectious agent
- Seasonal pattern
- Ability to trace potential index cases
- Geographical or man-made barriers of disease transmission
T or f: effective animal disease monitoring and control requires the involvement of private, state and federal scientists and veterinarians
true
