Which antibiotic class is Aeromonas hydrophila commonly susceptible to?

Aeromonas hydrophila is a gram-negative bacterium that can cause various infections, particularly in individuals with underlying health conditions or compromised immune systems. The antibiotic susceptibility profile of Aeromonas hydrophila is critical when considering treatment options for infections caused by this organism.

Fluoroquinolones are a class of antibiotics that are commonly used to treat infections caused by gram-negative bacteria, including Aeromonas species. This class of antibiotics is known for its efficacy against a wide range of pathogens, and studies have shown that Aeromonas hydrophila often exhibits susceptibility to fluoroquinolones such as ciprofloxacin and levofloxacin. The mechanism of action of fluoroquinolones involves inhibiting bacterial DNA synthesis, making them effective against many bacterial infections.

On the other hand, while Aeromonas hydrophila may show some susceptibility to other classes of antibiotics such as tetracyclines and macrolides, the broad susceptibility and effectiveness of fluoroquinolones make them a preferred choice in many clinical scenarios. Cephalosporins have varying effectiveness, but they are not universally reliable against Aeromonas hydrophila. Thus, fluoroquinolones are notably recognized as a primary option for treatment in this
