Which disease is associated with Aeromonas salmonicida?

• A. Koi herpesvirus disease
• B. Furunculosis
• C. White spot disease
• D. Columnaris disease

Answer: (B)

Aeromonas salmonicida is a well-known bacterial pathogen primarily affecting fish, particularly salmonids. The disease it causes, known as furunculosis, is characterized by the formation of boils or furuncles on the skin of infected fish. These lesions can lead to significant morbidity and mortality within affected populations. Furunculosis is marked by symptoms that may include erratic swimming, loss of appetite, and swelling, especially around the lateral line and dorsal area, where ulcerations may develop. The pathogenicity of Aeromonas salmonicida arises from its ability to produce a range of virulence factors, including toxins that compromise the fish's immune response. Understanding the specific diseases associated with various pathogens is crucial for effective aquatic veterinary practice, as it informs diagnosis, treatment, and management strategies for infected fish and helps in implementing biosecurity measures to prevent outbreaks.
