Two most common causes of infant meningitis are Streptococcus pneumoniae and Haemophilus influenzae. H. influenzae requires Factor X and Factor V as its growth factors, whereas S. pneumoniae is able to generate these two compounds on its own. If a 18-month-old infant was brought to the emergency room showing symptoms of meningitis, and samples from his cerebrospinal fluid (CSF) was collected and sent to the lab. The CSF samples were added onto different media to allow growth for 24 hours. According to the growth result below, which bacteria is likely to be the cause of meningitis in this case? Blood agar • No factor X • No factor V No Growth Media Result Answer: Chocolate agar • Has factor X Has factor V Growth Double check your spelling before submission!

Drug-resistant TB can be acquired via sequential mutations in the pathogen’s genome, or via transmission of a resistant pathogen from another person. How can these events be distinguished? Why is it important to know which is more prevalent?

45. A 5-year-old girl with a history of recurrent infections since the age of 4 months is brought to the physician for a follow-up examination. She has had multiple episodes of pneumonia, sinusitis, otitis media, and diarrhea. She is at the 20th percentile for height and weight. Her temperature is 37.4°C (99.3°F). Mild crackles are heard bilaterally over the lower lung lobes. Laboratory studies show: Leukocyte count Segmented neutrophils Eosinophils 10,500/mm³ (N=5500-15,500) 57% 2% Lymphocytes 34% CD3+ T lymphocytes 67% CD19+ B lymphocytes 28% CD56+ natural killer cells 5% Monocytes 7% Serum IgA IgG IgM undetectable (N=14-159 mg/dL) 25 mg/dL (N=345-1236) 410 mg/dL (N=43-207) This patient most likely has an abnormality of which of the following immune system components? A) Activation-induced deaminase B) CD40 ligand OC) Class II MHC protein D) Common y chain of the interleukin-2 (IL-2) receptor E) Recombination-activating gene 1 F) Terminal complement
