What type of bacteria is Aeromonas hydrophila?

• A. Gram-positive bacilli
• B. Gram-negative cocci
• C. Gram-negative bacilli
• D. Gram-positive cocci

Answer: (C)

Aeromonas hydrophila is classified as a Gram-negative bacillus, which is characterized by its rod shape and the inability to retain the crystal violet stain used in the Gram staining procedure. This classification is important in microbiology as it helps determine the appropriate treatments for infections caused by this bacterium, influencing both the choice of antibiotics and understanding the potential pathogenesis associated with infections. Being Gram-negative means that Aeromonas hydrophila possesses an outer membrane that contains lipopolysaccharides, contributing to its virulence and making it resistant to certain antibiotics that target Gram-positive bacteria. This information is crucial for veterinary professionals to correctly identify and manage infections in aquatic species and other animals.
