Cytomegalovirus vaccine Not available for preventing congenital infection
DNA-based vaccine Hay fever vaccine
Influenza vaccine Annual vaccination required
Leukemia vaccine Successful in cats
Polio vaccine Has reduced disease by 99%

Members of the Streptococcus pyogenes species are almost always ________-hemolytic. beta
A characteristic of necrotizing fasciitis is that it: all of the above: a. is known as the “flesh-eating” bacteria. b. is caused by Streptococcus pyogenes. c. destroys the tissue covering the muscles.
Streptolysin O is: the most frequently used serologic indicator of a recent streptococcal infection.
Streptolysin S is: an oxygen-stable enzyme.
Laboratory diagnosis of S. pyogenes can be made by: all of the above: a. culturing of throat or nasal specimens. b. ASO procedure. c. anti–DNase B (ADN-B)
An elevated antistreptolysin O (ASO) titer indicates: relatively recent streptococcal infection.
Most patients who have Streptococcus pyogenes infection begin to demonstrate a rise in antibody titer in ______days. 7
The classic antistreptolysin O (ASO) procedure has been replaced by: optical immunoassay procedure.
Serologic testing for S. pyogenes should compare acute and convalescent specimens collected ________ apart. 3 weeks
The principle of the optical immunoassay involves: anti-GAS (antibody) being attached (immobilized) to a thin film
Syphilis develops in which percentage of the sexual partners of persons with syphilitic lesions? 30% to 50%
In infected donor blood, Treponema pallidum does not appear to survive in citrated blood stored at 4° C for more than _____day(s). 3
Before clinical or serologic manifestations, the incubation period for syphilis usually lasts ______________________. about 3 weeks
The term for nontreponemal antibodies produced by syphilis-infected patients against components of their own or other mammalian cells is: reagin antibodies
The nontreponemal antibody produced by syphilis-infected patients can also be produced by patients with: all of the above: a. other infectious diseases. b. leprosy, tuberculosis, leptospirosis, or malaria. c. autoimmune disorders, drug addiction, or old age.
Tertiary syphilis is best evaluated by using: cerebrospinal fluid.
The substance detected by the RPR assay is: a reagin.
Untreated congential syphilis can lead to: all of the above: a. stillbirth. b. neonatal death. c. infant disorders.
A biological false-positive reaction is least likely to occur with which syphilis assay? both b and c: b. MHA-TP. c. FTA-ABS.
If an RPR assay is negative but has a rough appearance, what is an appropriate follow-up step? Repeat the assay with serial dilutions.
What is the causative agent of Lyme disease? Borrelia burgdorferi
Most cases of Lyme disease in the United States remain concentrated in the ________ regions. all of the above: a. northeastern b. north-central c. Pacific coastal
The CLIA-waived procedure for presumptive testing for Lyme disease is which of the following? PreVue assay for Borrelia burgdorferi
White-footed mouse Preferred host for larval and nymphal stages of Ixodes scapularis
White-tailed deer Preferred host for I. scapularis adult stage
Electrophoresis is defined as both a and b: a. migration of charged solutes in an electrical field. b. migration of charged particles in an electrical field.
Separation of proteins by electrophoresis is based on: rate of migration of individual components in an electrical field.
In immunoelectrophoresis (IEP), when a favorable antigen-antibody ratio (equivalence point) is reached, the antigen-antibody complex becomes visible as: all of the above: a. precipitation lines. b. precipitation bands c. a line representing one specific protein.
Differentiation of proteins using immunoelectrophoresis is based on: all of the above: a. electrophoretic mobility. b. diffusion coefficient. c. antibody specificity.
The immunoelectrophoresis of a normal serum typically depicts IgM, IgG, and IgA bands, but IgD and IgE bands are missing because of: normal concentrations of IgD and IgE are too low to be detected.
A monoclonal gammopathy is: all of the above: a. frequently diagnosed condition using immunoelectrophoresis (IEP). b. condition in which a single clone of plasma cells produces increased levels of a single class of immunoglobulin. c. condition in which a single clone of plasma cells produces increased levels of a single type of immunoglobulin.
Monoclonal gammopathies can be observed in: all of the above: a. malignancy. b. multiple myeloma. c. macroglobulinemia.
The most common application of immunoelectrophoresis (IEP) of urine is: demonstration of Bence Jones (BJ) protein.
The difference between polyvalent and monovalent antisera is that polyvalent antisera: both a and b: a. confirm the presence of major factors. b. confirm the presence or absence of factors.
The primary application of immunofixation electrophoresis (IFE) is for: characterization of monoclonal immunoglobulins
