Question 1

Match the types of bonding with the correct definition.
-Symptoms of acquired T. gondii infection can

Accepted Answer

Symptoms of acquired Toxoplasma gondii (T. gondii) infection can indeed be mild or resemble infectious mononucleosis, which includes symptoms like fatigue, fever, sore throat, and swollen lymph nodes. There is no direct association between T. gondii infection and causing urinary tract infections.

Question 2

Match the types of bonding with the correct definition.
-Any positive result in a pregnant patient confirmed as positive by a second reference laboratory should be evaluated by

Accepted Answer

Amniocentesis testing by PCR for T. gondii is used to confirm congenital toxoplasmosis in a fetus when a pregnant patient tests positive for T. gondii.

Question 3

Match the types of bonding with the correct definition.
-The preferred method for detection of T. gondii is

Accepted Answer

B

Question 4

Match the types of bonding with the correct definition.
-The avidity result is determined using

Accepted Answer

Avidity testing involves comparing the strength of antibody-antigen interactions in the presence and absence of a chaotropic agent like urea, which is reflected in the ratios of antibody titration curves of urea-treated and untreated sera.

Question 5

Match the types of bonding with the correct definition.
-IgM antibodies to T. gondii in an adult are an indication of

Accepted Answer

IgM antibodies are typically produced as a first response to an infection, indicating a current or recent exposure to the pathogen, in this case, Toxoplasma gondii.

Question 6

Match the types of bonding with the correct definition.
-The definitive host of Toxoplasma gondii is the

Accepted Answer

The definitive host of Toxoplasma gondii, where it can reproduce sexually, is the house cat (Felis catus).

Question 7

Match the types of bonding with the correct definition.
-Transfusion-transmitted toxoplasmosis is associated with

Accepted Answer

The answer of Match the types of bonding with the...

Question 8

Match the types of bonding with the correct definition.
-Major sources of increasing human infection with T. gondii include all the following except

Accepted Answer

T. gondii, or Toxoplasma gondii, is primarily transmitted to humans through ingestion of undercooked, contaminated meat, consumption of food or water contaminated with oocysts shed in the feces of infected cats, and from mother to fetus. Transmission through bloody body fluids is not a recognized route of infection for T. gondii.

Question 9

Match the types of bonding with the correct definition.
-The best evidence of toxoplasmosis infection is a significant change in

Accepted Answer

The best evidence of toxoplasmosis infection is a significant change in antibody levels between two appropriately timed specimens, which can include both acute and convalescent specimens, analyzed either at the same time or at different times in the laboratory. This encompasses all the options provided.

Question 10

Match the types of bonding with the correct definition.
-Toxoplasma-infected mothers who are not treated can give birth to a(n)

Accepted Answer

Toxoplasma infection in pregnant women can lead to congenital infection in the infant, meaning the infection is passed from the mother to the baby during pregnancy.

Question 11

Match the types of bonding with the correct definition.
-Congenital toxoplasmosis can result in

Accepted Answer

Congenital toxoplasmosis can lead to central nervous system malformations and prenatal mortality, making both A and B correct.

Question 12

Match the types of bonding with the correct definition.
-Toxoplasma gondii antibody assay can demonstrate antibodies within __________ after infection.

Accepted Answer

Toxoplasma gondii antibody assays can typically demonstrate antibodies within 2 weeks after infection, as the immune system takes some time to produce antibodies in detectable levels.

Question 13

Match the types of bonding with the correct definition.
-The Centers for Disease Control and Prevention (CDC) suggests that any confirmed equivocal or ____________ test results for toxoplasmosis should be retested using a different assay.

Accepted Answer

The CDC recommends retesting any confirmed equivocal or positive test results for toxoplasmosis using a different assay to ensure accuracy and confirm the diagnosis.

Question 14

Match the types of bonding with the correct definition.
-The PCR assay for T. gondii can be performed on

Accepted Answer

The PCR assay for T. gondii can be performed on various types of samples including serum or plasma, fresh or frozen biopsy tissue, and cerebrospinal fluid, making all the options correct.

Question 15

Match the types of bonding with the correct definition.
-After IgM-positive sera undergo confirmatory testing, the results are interpreted as a(n)

Accepted Answer

The correct interpretation of confirmatory testing after IgM-positive sera can include a recently acquired infection, an infection acquired in the past, or a false-positive test result, depending on the specific confirmatory test results and the context of the testing.

Question 16

Match the types of bonding with the correct definition.
-All mammals can transmit T. gondii by

Accepted Answer

Transplacental transmission is the correct match for the method by which all mammals can transmit T. gondii, as it refers to the transmission of the parasite from an infected mother to her fetus through the placenta.
