2 Antimicrobial Agents Antimicrobial agents are medications used in the treatment of infections caused by microbes such as bacteria, fungus, virus, and protozoa. Arcangelo, Peterson, Wilbur, & Reinhold (2017) write that when selecting the appropriate antimicrobial agents, factors such as medical history, site of infection, immune status, iv drug use, setting in which the infection occurred as well as culture and sensitivity testing should all be taken into consideration. According to Arcangelo et al. (2017) antimicrobials include classes of drugs such as antibacterial or antibiotics, antifungal, antiviral, and antiparasitic. Among these classes, antibiotics are the ones frequently used. However, Werth (2018) warn against the indiscriminate use of antibiotics in treating infections caused by viruses or other microbes as this can lead to bacteria resistance as well as exposing the patient to drug complication. The purpose of this paper is to describe the categories of antimicrobial agents, the differences between viral and bacterial infections as well as explain why proper identification of viral and bacterial infections is key to the selection of proper antimicrobial agents Categories of Antimicrobial Agents In using antimicrobials in the treatment of infection, it is important to identify the causative organism. According to Arcangelo et al. (2017, identifying the causative organism is always the goal because it allows for both optimal selection of antibiotic and patient outcome. Arcangelo et al (2017) further reports that antibiotics are usually started before culture and sensitivity testing results are out by using empirical antibiotic therapy but warn against initiating antibiotics before cultures and sensitivity specimen such as urine and blood are obtained.
