What is the most appropriate sample to be collected to isolate the causative agent of the infection? * A 46-year-old male encountered a motor-vehicular accident (MVA) resulting in multiple injuries on his anterior chest and left lower extremities. Aside from the injury, his medical history was unremarkable. The patient was admitted for nine days and underwent debridement and was discharged with an external fixator. However, during his admission, on his 7m post-operative day, the wound was noted to have persistent purulent, bloody discharge from drain site, which is highly suggestive of surgical site infection (SSI). Whole blood Debridement Serum Discharge from drain site
- From , figure Explain how this technique can beused to diagnose infections with group A streptococci.Read the following study, construct the appropriate 2x2 table, calculate the measure of association, state the study design, and state the interpretation of the results.An outbreak of listeriosis is occurring in Michigan. The cases are sporadic and not linked to a common group or event. Preliminary reports suggest an association of illness with pre-packaged salads. Investigators identified cases by hospital and laboratory reports. Interviews were conducted on 60 patients found with laboratory confirmed listeriosis and 90 well people from randomly selected households. Case-patients and well people were similar with respect to age, sex, and level of education. Forty-five (45) people with listeriosis reported consuming pre-packaged salad. Nine (19) well people reported consuming pre-packaged salad. 2x2 table + - Total + A B A+B - C D C+D Total A+C B+D A+B+C+D List the values for each cell: A, B, C, D, A+B, C+D, A+C, B+D, A+B+C+D…For an In vitro mimicking infection test:
