The assignment content discusses the development and benefits of fever in the context of Mary's injury infection with Staphylococcus aureus. Fever is beneficial as it can stop the increase of pathogenic microorganisms by exhausting minerals essential for bacterial replication, and promoting phagocytosis and the disposal of pathogens. The endogenous source of contamination is the skin and mucosal surfaces, while the exogenous source could be through contact with contaminated surfaces or individuals. Augmentin, a combination of amoxycillin and clavulanic acid, is an appropriate antibacterial agent prescribed to Mary as it is effective against antibiotic-resistant Staphylococcus aureus. The added benefits of Augmentin include its ability to inhibit beta-lactamase, rendering the antibiotic ineffective.
