【評論內容】雞糠蚊是屬於蠓科的一種吸血昆蟲，嗜食雞血；當它吸食病雞血液後，血球中的雄性和雌性配殖體，在其體內結合並發育。經2~7天發育成感染性胞子蟲，集合在該蠓的唾液腺內，等待機會。當雞糠蚊再吸食健康雞血時，這些胞子蟲即隨著唾液進入健康雞體內。分佈在肺、脾、腎、心肌、肝、肌肉等各器官組織之組織細胞中，開始兩個世代之無性生殖期，經過約十二至十三天。成熟裂殖體直徑約20~200mu之間，肉眼可見呈白點狀，破裂後放出許多的裂殖子，第一代裂殖子可再侵入其他健康之血管細胞中發育為第二代裂殖體；至於第二代裂殖子則可侵入紅血球內，開始有性生殖時期，期間約八至十二天，發育為雌性配殖體和雄性配殖體，成為雞糠蚊的新感染源。我也覺得在雞的血液內??http://vettech.nvri.gov.tw/Articles/ahm/349.html
