IgG and IgM antibodies specific to Toxoplasma gondii were determined simultaneously by IFAT in cats. Group 1 included 357 cats with various diagnoses, but negative for FeLV and FIV. Specific IgG antibodies in titres ranging from 10 to 2560 (mean 247) were detected in 61.3% animals, specific IgM antibodies were found only in one cat (0.28%) in titre 1:40 showing an IgG titre of 160. Oocyst shedding was demonstrated in one cat (0.28%) showing an IgG titre of 1:40. Group 2 included 33 cats positive for FeLV or FIV. IgG antibodies in titres ranging from 10 to 640 (mean 101) were found in 63.6% cats. Neither IgM antibodies nor shedding of T. gondii oocysts were detectable. Clinically unapparent toxoplasmosis, manifested by the presence of IgG antibodies is frequent in cats; the opportunistic character of the infection is important.
通过间接荧光抗体试验（IFAT）同时检测猫体内针对刚地弓形虫的IgG和IgM抗体。第1组包括357只患有各种疾病诊断但猫白血病病毒（FeLV）和猫免疫缺陷病毒（FIV）检测呈阴性的猫。在61.3%的动物中检测到滴度范围为10至2560（平均247）的特异性IgG抗体，仅在1只猫（0.28%）中发现特异性IgM抗体，滴度为1:40，IgG滴度为160。在1只IgG滴度为1:40的猫（0.28%）中证实有卵囊排出。第2组包括33只FeLV或FIV检测呈阳性的猫。在63.6%的猫中发现滴度范围为10至640（平均101）的IgG抗体。未检测到IgM抗体和刚地弓形虫卵囊排出。猫中由IgG抗体的存在所表现出的临床隐匿性弓形虫病很常见；该感染的机会性特征很重要。
