QUESTION 11 Through the microscope, these bacteria appear as Gram-positive cocci typically arranged in irregular and often grape-like clusters. Approximately 30% of adults and most children are healthy nasal carriers. The portal of entry is usually the skin and the source of the organism is typically a healthy nasal carrier or direct contact with an abscess from an infected individual. The bacterium typically causes pus-filled inflammatory lesions known as abscesses and may cause systemic infections such as septicemia, septic arthritis,...
