The reservoir competence of the lesser mealworm, Alphitobius diaperinus (Panzer) is reported for Salmonella typhimurium (Loeffler) relative to broiler chicken production. Salmonella typhimurium was isolated from feces of the adult lesser mealworm at least 28 d after feeding for 24 h on 1 g of chicken feed inoculated with 3 x 10(8) bacteria/ml. All larvae fed S. typhimurium ceased voiding the bacteria in their feces before pupal molt, except one. One beetle continued to void S. typhimurium after it emerged as an adult, providing evidence that transstadial transmission of S. typhimurium may occur. The bacteria were found both on the external body surface and inside the body of surface-sterilized adults and larvae during 16 d of exposure. Salmonella-positive cloacal swabs were obtained from 1-day-old broiler chicks within 24 h after eating one infected lesser mealworm adult or larva.
就肉鸡生产而言,报道了赤拟谷盗(Alphitobius diaperinus (Panzer))对鼠伤寒沙门氏菌(Salmonella typhimurium (Loeffler))的带菌能力。在用接种了3×10⁸ 个细菌/毫升的1克鸡饲料喂养24小时后,至少28天从成年赤拟谷盗的粪便中分离出鼠伤寒沙门氏菌。除一只幼虫外,所有喂食鼠伤寒沙门氏菌的幼虫在化蛹前停止在粪便中排出该细菌。一只甲虫羽化成为成虫后继续排出鼠伤寒沙门氏菌,这证明鼠伤寒沙门氏菌可能会发生经龄期传播。在暴露的16天内,在体表消毒的成虫和幼虫的体表和体内都发现了该细菌。在食用一只受感染的赤拟谷盗成虫或幼虫后的24小时内,从1日龄的肉鸡雏鸡中获得了沙门氏菌阳性泄殖腔拭子。
