摘 要:采用鸡球虫单卵囊感染雏鸡,对雏鸡日龄及生物学特性进行了研究。结果表明,1、7、15和30d雏鸡的感染成功率分别为63.3%、60%、3.33%和0;与该种球虫鉴定时的指标相比,潜隐期从141h延长至(176.6±7.2)h,卵囊由(20.16±1.16)μm×(15.59±1.13)μm增大至(24.32±1.3)μm×(18.61±0.75)μm,孢子囊由(11.64±0.85)μm×(5.86±0.59)μm增大至(12.89±0.85)μm×(7.51±0.25)μm;显露期为(49.8±5.62)h,每鸡排出8.42×104个卵囊。The chicks at different ages were infected with a single oocyst of Eimeria tenella , and some biological characters were observed The results showed that the incidences of infection in the chicks at 1, 7, 15 and 30 days old were 63 3%, 60%, 3 33% and 0, respectively Compared with their parent, the pretatent period was prolonged from 141 h to (176 6±7 2) h The oocysts and sporocysts were increased from (20 16±1 16)μm×(15 59±1 13)μm to (24 32± 1 3)μm ×(18 61±0 75)μm and from (11 64±0 85)μm×(5 86±0 59)μm to (12 89±0 85)μm×(7 51±0 25)μm, respectively The patent period was (49 80±5 62) h The yield per oocysts was 8 42×10 4
