Sažetak

Hydropericardium syndrome (HPS) was produced after experimental infection of two different synthetic lines of chickens, white (B1) and coloured (B2) plumage broilers in their 3rd and 4th weeks of age. B1 broilers were found more susceptible and mortality ranged from 92.3% to 97%. B2 broilers were less susceptible and mortality ranged from 15.7% to 23.3%. Sixty percent mortality was observed in 3-week-old sentinel B1 broilers. Sixty percent of the B1 broilers chickens infected at eight weeks old died due to HPS, whereas B2 broilers showed no clinical signs, nor died, even at six weeks of age. High mortality was observed in B1 broilers following infection with chloroform-extracted homogenate of infective livers. HPS was a consistent feature in dead birds. Gross pathological lesions were observed in liver, kidney and heart. Microscopic lesions were observed in liver, kidney, Harderian gland, brain, heart, lung, pancreas, spleen and bursa. Some of the hepatocytes contained large basophilic intranuclear inclusion bodies. A difference in susceptibility of two synthetic lines of broiler chickens to HPS disease virus is recorded for the first time.
