A child presents with a characteristic "slapped cheek" rash followed by a lacy, reticular rash on the trunk and extremities. The causative agent is a single-stranded DNA virus belonging to the family Parvoviridae, known as:
정답: D
A 55-year-old male with a history of poorly controlled diabetes mellitus develops a necrotizing fasciitis of his left lower extremity following a minor abrasion sustained while gardening. Initialcultures of the wound reveal a polymicrobial flora, including Gram-positive cocci in chains and Gram-negative bacilli. Over the next 48 hours, despite broad-spectrum antibiotic therapy, the patient's condition deteriorates, and new bullae with hemorrhagic fluid appear. Gram stain of this fluid now predominantly shows large, Gram-positive bacilli with subterminal spores. Which of the following virulence factors is MOST likely contributing to the rapid tissue destruction observed in this patient?
정답: A
A 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?
정답: C
A patient with a history of intravenous drug use develops a fever and new heart murmur. Blood cultures are positive for Gram-positive cocci that are catalase-positive and coagulase-positive. The MOST likely complication of this infection is:
정답: A

정답: A
A patient with a history of neutropenia following chemotherapy develops a severe pneumonia.
Bronchoalveolar lavage fluid reveals the presence of hyaline, septate hyphae with frequent dichotomous branching at acute angles. Culture yields a filamentous fungus that produces conidiophores with a vesicle bearing phialides that release chains of conidia. The MOST likely genus is:
