Abstract :

In October 2023, a study was conducted to investigate an outbreak of inclusion body hepatitis in 100 desi birds (GOLDEN MISCRI) at Chak 88 Hasilpur Punjab, Pakistan. Secondary bacterial infection of Escherichia coli was observed after IBH. Birds were being reared in the backyard with the history of Newcastle disease vaccination. The flock experienced 1% mortality between the 11th and 12th week of age. Birds were treated for E. coli. Birds were found anorexic, dull, and depressed, with ruffled feathers, anemic comb, and wattles with yellow mucoid droppings. After the treatment, mortality was raised to 3%. Post-mortem investigation revealed straw-colored transudate in the pericardial sac, swollen kidneys, splenomegaly, hemorrhagic foci on the liver, hepatomegaly, cheesy white material on the liver, and edematous liver. IBH and E. coli were diagnosed based on clinical signs and postmortem findings. Birds were treated for the viral infection after stopping the anti-bacterial treatment and birds started feeding with reduced mortality. We observed that in poultry mix infection of IBH and E. coli if viral infection is covered first by supportive therapy and then treated for bacterial infection showed better results.
