Abstract

In October 1982 the death of approximately 1,500 wild ducks, mostly mallards (Anas platyrhynchos), and about 100 shore birds including greater yellowlegs (Tringa melanoleuca) was observed in the New York State Oak Orchard Wildlife Management Area. The lack of gross pathology, the signs exhibited by the moribund ducks, and the ecologic conditions indicated possible botulinal intoxication. Clostridium botulinum toxin type C was demonstrated in duck serum (approximately 5 X 10(4) mouse intraperitoneal LD50 of toxin per ml of serum) and in an extract from fly larvae (Lucilia spp.) taken from the same area (approximately 1 X 10(6) mouse intraperitoneal LD50 of toxin per gram of larvae).

摘要

1982年10月，在纽约州橡树果园野生动物管理区观察到约1500只野鸭（主要是绿头鸭，即绿头鸭属的绿头鸭）和约100只岸禽（包括大黄脚鹬，即黑脚鹬属的大黄脚鹬）死亡。由于缺乏明显的病理特征、濒死鸭子所表现出的症状以及生态条件，表明可能是肉毒中毒。在鸭血清中检测到了C型肉毒梭菌毒素（每毫升血清中约含5×10⁴小鼠腹腔注射半数致死量的毒素），并且在从同一区域采集的蝇蛆（丽蝇属）提取物中也检测到了该毒素（每克蝇蛆中约含1×10⁶小鼠腹腔注射半数致死量的毒素）。
