A clinical microbiology laboratory is validating a new point-of-care test for the rapid detection of influenza A and B viruses. To accurately determine the clinical sensitivity of the test, it should be compared to a gold standard method using:
A. A panel of known positive and negative samples stored at room temperature.A patient with a history of travel to a rural area develops a febrile illness with jaundice and dark urine. Peripheral blood smear reveals intraerythrocytic parasites with a characteristic Maltese cross morphology. The MOST likely causative agent is:
A. Plasmodium falciparumAccording to the current CDC-recommended laboratory algorithm for diagnosing HIV infection in adults and children aged >18 months, what is the recommended initial screening test?
A. HIV-1 p24 antigen assay onlyA clinical microbiology laboratory is performing quality control on antimicrobial susceptibility testing. The zone diameter for Escherichia coli ATCC 25922 tested against ciprofloxacin is consistently smaller than the acceptable range published by CLSI. The MOST likely cause of this discrepancy is:
A. Use of expired antibiotic disksA patient with HIV infection and a very low CD4+ T-cell count develops a disseminated infection with a fungus that is commonly found in pigeon droppings. The MOST likely causative agent is:
A. Candida glabrataA patient presents with perianal itching, particularly at night. Microscopic examination of cellophane tape preparation from the perianal area reveals oval-shaped eggs with one flattened side. The MOST likely causative organism is:
A. Ascaris lumbricoidesA 30-year-old female who recently returned from a hiking trip in the northeastern United States presents to her physician with a two-week history of a slowly expanding, erythematous rash with central clearing on her thigh. She also reports intermittent fatigue, arthralgias, and mild headache. Serological testing reveals a positive IgM and IgG response to Borrelia burgdorferi. Which of the following mechanisms is MOST significant in the pathogenesis of the clinical manifestations observed in this patient?
A. Production of potent exotoxins leading to direct tissue damageDuring a community outbreak of influenza, a public health laboratory performs rapid antigen testing on nasopharyngeal swabs. A test for influenza A is positive, but the influenza B test is negative. Subsequently, RT-PCR is performed on the same sample, and it is negative for both influenza A and B viral RNA. The MOST likely explanation for this discordant result is:
A. The rapid antigen test has low sensitivity, resulting in a false positive.A patient with severe combined immunodeficiency (SCID) develops a progressive respiratory illness. Bronchoalveolar lavage fluid is examined using direct fluorescent antibody (DFA) staining, which reveals numerous cysts of Pneumocystis jirovecii. The cysts appear:
A. Small and round with a thick wall, containing sporozoites.An immunocompromised patient develops a disseminated fungal infection. Tissue biopsy reveals small (2-4 μm) yeast cells within macrophages. The patient has a history of living in the Ohio and Mississippi River valleys. The MOST likely causative agent is:
A. Blastomyces dermatitidisNowadays, the certification exams become more and more important and required by more and more enterprises when applying for a job.
