Experimental Absidia corymbifera infection in rabbits: clinicopathological studies.
Absidiosis was produced experimentally in rabbits by intravenous inoculation of 1.4 x 10(5) spores of Absidia corymbifera. Infected rabbits exhibited a rise in body temperature, anorexia, dullness, listlessness, diarrhoea, occasional blindness, convulsions and death in some cases. Mortality occurred mainly between 6 to 9 days post infection (DPI) and overall mortality was 50 per cent during the three week observation period. No significant difference was observed in erythrocytic indices viz., Hb, PCV, TEC in control and infected rabbits. However, erythrocyte sedimentation rate was considerably increased in the infected rabbits. A state of leucocytosis was observed in the infected rabbits, which was due to increase in the relative percentage of neutrophils and decrease in lymphocytes. There was a significant increase in blood urea nitrogen concentrations of infected rabbits from 3 to 14 DPI as compared to controls, but serum creatinine values were not significantly altered at any stage of infection. The cause of death was attributed to kidney failure and uraemia in infected rabbits. The rabbit was found to be a suitable model for the study of absidiosis.
