Abstract

Following subcutaneous injection of oil emulsified NEWCASTLE DISEASE vaccine, about 400 out of 40000 chicks in a 5 weeks old broiler breeder farm showed severe local reactions at posterior part of their neck, head and face. One week before, all of the chicks of this farm were subcutaneously injected with an oil-emulsified NEWCASTLE DISEASE vaccine in posterior part of their neck. Postmortem examination of the affected chicks revealed thickening and hardening of subcutaneous tissues of the affected areas. In addition, many white to grayish foci about few mm up to 1 cm in diameter were seen in subcutaneous tissues of the neck. In histopathological sections,. granulomatous dermatitis and granulomatous myositis were diagnosed at the site of injection. Granulomas had typical structure consisted of central cystic cavity and debris of necrotic cells that were surrounded by giant cells with numerous nuclei. Around these lesions, myxomatous connective tissue and mononuclear inflammatory cells including macrophages, lymphocytes, plasma cells and few heterophils were present. Cysts with inflammatory reactions, scattered giant cells and fibroplasia were observed in the tissues between granulomas. Special staining such as Periodic-acid-schiff and Brown-brenn gram stain of the histologic sections did not show any fungior bacteria. These lesions were disappeared after 3, weeks without any treatment and thus it is presumed that these lesions might be postvaccinal allergic reactions due to oil adjuvants of vaccine.
