This high-yield material covers basic microbiology concepts, with a breakdown of exam emphasis: ~40% bacteriology, 25% immunology, 25% virology, with smaller portions for parasitology and mycology. Questions typically involve identifying the causative organism from a clinical presentation and then recalling a specific feature of that organism. The content is presented in individual microbial profiles and by the systems they infect, requiring familiarity with both formats.
Este material de alto rendimiento cubre los conceptos básicos de microbiología. El énfasis en exámenes anteriores ha sido aproximadamente 40% bacteriología (20% básica, 20% cuasi-clínica), 25% inmunología, 25% virología (10% básica, 15% cuasi-clínica), 5% parasitología y 5% micología. Las preguntas de microbiología en el examen Step 1 a menudo requieren dos (o más) pasos: Dada una presentación clínica determinada, primero deberá identificar el organismo causante más probable y luego deberá proporcionar una respuesta sobre alguna característica de ese organismo. Por ejemplo, la descripción de un niño con fiebre y un sarpullido petequial irá seguida de una pregunta que diga: "¿De qué sitio suele entrar el organismo responsable en la sangre?" Por lo tanto, esta sección presenta organismos de dos maneras principales: en "perfiles" microbianos individuales y en el contexto de los sistemas que infectan y las presentaciones clínicas que producen. Debe familiarizarse con ambos formatos. Al revisar el enfoque por sistemas, recuérdese las características de cada microbio volviendo a los perfiles individuales. También asegúrese de memorizar las características de laboratorio que le permiten identificar microbios.
Front | This high-yield material covers the basic concepts of microbiology. The emphasis in previous examinations has been approximately 40% bacteriology (20% basic, 20% quasi-clinical), 25% immunology, 25% virology (10% basic, 15% quasi-clinical), 5% parasitology, and 5% mycology. Microbiology questions on the Step 1 exam often require two (or more) steps: Given a certain clinical presentation, you will first need to identify the most likely causative organism, and you will then need to provide an answer regarding some feature of that organism. For example, a description of a child with fever and a petechial rash will be followed by a question that reads, “From what site does the responsible organism usually enter the blood?” This section therefore presents organisms in two major ways: in individual microbial “profiles” and in the context of the systems they infect and the clinical presentations they produce. You should become familiar with both formats. When reviewing the systems approach, remind yourself of the features of each microbe by returning to the individual profiles. Also be sure to memorize the laboratory characteristics that allow you to identify microbes. |
