柏氏禽刺螨在中药材薏苡仁中的耐受力

Investigation on the infestation and environment tolerance of Ornithonyssus bacoti in stored traditional Chinese herb Semen Coicis

目的调查中药材薏苡仁是否存在柏氏禽刺螨污染,以及该螨在薏苡仁中的耐受力。方法取800 g储藏中药材薏苡仁过40目分样筛,筛取80 g薏苡仁碎屑。从薏苡仁碎屑中直接分离螨,制作玻片标本,参照文献对分离的螨类进行螨种鉴定。结果从80 g储藏中药材薏苡仁碎屑中共分离出螨449只,经鉴定,该螨为柏氏禽刺螨(ornithonyssus bacoti)。结论首次在储藏中药材薏苡仁中发现柏氏禽刺螨,并且污染严重,应予以重视,谨防柏氏禽刺螨作为传播媒介传播病原体引起的疾病。

Objective To investigate the infestation status and environment tolerance of ornithonyssus bacoti(O. bacoti) in stored traditional Chinese herb Semen Coicis(Coix seed). Methods 800 g of stored Semen Coicis was initially taken, and subjected to passing a 40-mesh sampling sieve. Then 80 g of Coix seed particles was sampled to directly isolate the mites that were made into slide specimen in conventional technique, and identified as the procedures described in previous literature. Results A total of 449 mites were isolated from the 80 g stored Semen Coicis particles, and were identified as O. bacoti. Conclusions O.bacoti was first detected in the stored traditional Chinese medicinal Semen Coicis with which infestation is serious. This status should call out attention to prevent the disease associated with transmission of pathogens from O.bacoti.
