Write 4 pages with APA style on Opportunistic Microbial Infections. Opportunistic Infections Immmunocompromised patients are vulnerable to opportunistic infections caused by organisms of lower pathogenecity, besides being also susceptible to primary pathogens causing disease among immunocompetent hosts resistant to opportunistic infections. “Many opportunistic infections arise from the individual’s own flora or local environment”2, at or near the microbes’ normal sites of colonization. Hence, some normal flora species are associated with particular opportunistic infections. For example, Bacteroides fragilis is associated with abdominal infections, Staphylococcus epidermidis with catheter infections, and Escherichia coli with urinary tract infections3. Bacterial Opportunistic Infection Staphylococcus aureus causes the greatest number of pyodermas and soft tissue infections. It is not one of the cutaneous resident flora, however “it colonizes the anterior nares in up to 25% of healthy individuals at any one time and more than 50% of chronically ill individuals”4.
