In this study, we investigated the influence of body-size and temperature on the susceptibility of carp Cyprinus carpio to the new ulcer disease caused by atypical Aeromonas salmonicida. We observed that 4–7 cm long carp, weighing 1.6–8.6 g, exhibited similar susceptibility to the disease. Furthermore, A. salmonicida cultured at 25°C demonstrated significantly reduced virulence compared to the bacterium cultured at 20°C. Additionally, a higher disease occurrence rate was noted at a water temperature of 25°C during infection, with faster symptom recovery.
