Abstract

兵庫県下の食鳥処理場で処理された県内産鶏を対象とし, 77農場418羽についてクリプトスポリジウムのオーシスト保有状況調査を実施した. ショ糖を用いた遠心沈殿浮遊法による検査の結果, 14農場37羽の糞便からクリプトスポリジウムのオーシストが検出され, 陽性率は8.9%であった. 糞便からオーシストが検出された検体について気管, 十二指腸, 盲腸, 直腸およびファブリキウス嚢を組織学的に検索した. その結果, ファブリキウス嚢を採取できた33検体中18検体の粘膜上皮表層にクリプトスポリジウム原虫を多数認めた. 検出されたオーシストは, 形態, 寄生部位から<I>Cryptosporidium baileyi</I>と考えられた.

Examinations to detect <I>Cryptosporidium</I> oocysts were performed on 418 chickens bred on 77 farms in Hyogo Prefecture. Fecal examinations using the sucrose centrifugal flotation technique showed 37 samples (8.9%) from 14 farms to be positive for oocysts. Histological examinations were performed on the trachea, duodenum, ceca, rectum, and bursa of Fabricius obtained from chickens that tested positive. Oocysts were observed in 18 of the 33 samples from which we were able to collect the bursa of Fabricius. The oocysts were parasitized on. the mucous-epithelial surface of the bursa. On the basis of size, shape, and parasitizing organ, parasites detected throughout this survey were presumed to be <I>Cryptosporidium baileyi</I>.
