What two types of viral hepatitis are transmitted via fecal-oral routes?
HAV, HEV
What virus causes infectious mononucleosis
Epstein-Barr Virus (EBV)
True or false a virus contains either RNA, DNA or both?
False. only one
The confirmatory testing method for HIV
Western Blot
The non-treponemal tests : RPR and VDRL test for :
Reagin
Infection with Hepatitis D virus requires what?
Hep B
the monospot test for IM is picking up what type of antibody ?
Heterophile
This virus is a member of the Flaviviridae family and transmitted from infected birds to humans via mosquitos. It is the leading cause of mosquito borne disease in the US
West Nile Virus
a highly sensitive laboratory technique designed to detect and quantify substances like antibodies, antigens, proteins, and hormones in samples such as blood. It works by using antibodies to bind target molecules, followed by an enzyme-linked reaction that causes a color change, indicating a positive result
ELISA - enzyme linked immunosorbent assay
What test should be done if neurosyphilis is suspected?
What hepatitis B test indicates immunity either from past infection or vaccination?
Anti-HBs - Hep B surface antibody
A rare, aggressive, and fast-growing form of B-cell non-Hodgkin lymphoma, often affecting children, which develops in lymph nodes, the abdomen, or the jaw. It is associated with EBV infections
Burkitt's lymphoma
This single stranded RNA virus is also known as German Measles
Rubella
a sensitive immunological technique used to detect antibodies by coating carrier red blood cells (usually from sheep) with soluble antigens. When mixed with a serum sample containing specific antibodies, the coated cells clump together, indicating a positive result,
Passive hemagglutination
What stage of syphilis includes Gummas formation?
tertiary
What hep B test indicates a current infection and is the first to appear positive?
HBsAg
The Mumps virus is a single stranded RNA virus that can cause systemic infection characterized by inflammation of what glands?
Parotid
This virus is endemic to Japan is known to cause adult T cell leukemia-lymphoma .
HTLV-1
What methodology is used for enumerating CD4 T cells in HIV infections to monitor treatment and disease progression? At what value is the patient considered to have AIDS?
Flow Cytometry - < 14%
During the latent phase of syphilis patients are unable to pass the infection to others with one exception:
pregnant women can pass to fetus
hepatitis B test that indicates high infectivity
HBeAg
The presence of CMV may be detected on viral culture by looking for what type of effects ?
Cytopathic effects
These two surface proteins found on Influenza virus are used to type viruses for epidemiologic purposes
Hemagglutinin ( H ) and Neurominidase ( N)
In the acute phase of syphilis testing a patient had a titer of 1:8 . What must the titer be in the convalescent phase to indicate a recent or active infection?
at least 1:32
