Sera from 397 sheep and 290 goats slaughtered at Tabouk Official Abattoir were examined for anti-Toxoplasma IgG by LAT, IHAT & IFAT. The results showed infection rates 23.4, 41.8 & 52.2% (P < 0.001) in sheep and 19.3, 40.7 & 51.7% (P < 0.001) in goats by the 3 tests respectively. Infection rates were higher in sheep than goats (P > 0.05), relatively nearby in local and imported sheep (P > 0.05), higher in imported goats than local ones (P > 0.05) and higher in female sheep and goats than males (p > 0.05). High titers were in goats than in sheep (P < 0.001). IFAT showed highest sensitivity (100% & 96.7%), specificity (97.1% & 96.1%) and highest diagnostic accuracy (98.5% & 96.9%) in sheep and goats respectively. The IHAT showed high diagnostic accuracy and high applicability. The interpretation of results and recommendations were presented.
对在塔布克官方屠宰场宰杀的397只绵羊和290只山羊的血清，采用乳胶凝集试验（LAT）、间接血凝试验（IHAT）和间接荧光抗体试验（IFAT）检测抗弓形虫IgG。结果显示，这三种检测方法在绵羊中的感染率分别为23.4%、41.8%和52.2%（P<0.001），在山羊中的感染率分别为19.3%、40.7%和51.7%（P<0.001）。绵羊的感染率高于山羊（P>0.05），本地绵羊和进口绵羊的感染率相对接近（P>0.05），进口山羊的感染率高于本地山羊（P>0.05），雌性绵羊和山羊的感染率高于雄性（P>0.05）。山羊的抗体滴度高于绵羊（P<0.001）。IFAT在绵羊和山羊中分别显示出最高的敏感性（100%和96.7%）、特异性（97.1%和96.1%）和最高的诊断准确性（98.5%和96.9%）。IHAT显示出较高的诊断准确性和适用性。文中给出了结果解读和建议。
