Sаm, а cоllege freshmаn with a bad habit оf оversleeping, nicked himself shaving in a rush to get to class on time. At the time, he didn’t think twice about it. But two days later, he noticed the cut was surrounded by a reddish area of skin that was warm to the touch. When the wound started oozing pus, he decided he had better stop by the university’s clinic. What is pus? [color1] The doctor took a sample from the lesion and then cleaned the area. Observing that Sam’s wound is purulent, the doctor tells him that he probably has a bacterial infection. Which leukocytes would most likely increase in number in response to this infection? [color2] She takes a sample from the lesion to send for laboratory analysis, but because it is Friday, she does not expect to receive the results until the following Monday. In the meantime, she prescribes an over-the-counter topical antibiotic ointment. She tells Sam to keep the wound clean and apply a new bandage with the ointment at least twice per day. Sam has a(n) [color3]. The first leukocytes to arrive to an injured site are [color4]. Through [color5] these cells squeeze through the leaking blood vessels and the monocytes mature into [color6]. Sam uses the topical antibiotic over the weekend to treat his wound, but he does not see any improvement. On Monday, the doctor calls to inform him that the results from his laboratory tests are in. The tests show evidence of both Staphylococcus and Streptococcus in his wound. The bacterial species were confirmed using several tests. A passive agglutination test confirmed the presence of S. aureus. In this type of test, latex beads with antibodies cause agglutination when S. aureus is present. Streptococcus pyogenes was confirmed in the wound based on bacitracin (0.04 units) susceptibility as well as latex agglutination tests specific for S. pyogenes. Because many strains of S. aureus are resistant to antibiotics, the doctor had also requested an antimicrobial susceptibility test (AST) at the same time the specimen was submitted for identification. The results of the AST indicated no drug resistance for the Streptococcus spp.; the Staphylococcus spp. showed resistance to several common antibiotics, but were susceptible to cefoxitin and oxacillin. Once Sam began to use these new antibiotics, the infection resolved within a week and the lesion healed.
