采用间接免疫荧光法检测了27只患病个体饲养的血小板减少症犬（血小板浓度低于200，000血小板/微升）和59只健康犬舍犬（位于路易斯安那州南部）血清中的犬埃立克体、扁平埃立克体和斑点热群（SFG）立克次体抗体。在63%的患病血小板减少症犬和6.8%的健康犬舍犬中检测到血小板浓度低于100，000血小板/微升。一只患病的血小板减少症犬在血小板内检测到胞浆内E板桑椹胚。犬、盘埃立克体抗体阳性率分别为25.9%和40.7%，健康犬分别为20.3%和54.2%。对犬埃立克次体呈血清阳性的所有犬对扁平埃立克次体的抗体滴度均升高至大于或等于1：100。同时检查血清抗体滴度增加（大于或等于1：64），以四个SFG立克次体表明，立克次体rhipicephali和立克次体蒙大拿占大多数的抗体检测在这些狗。在86只受试犬中，44.2%的犬对犬立克次体、扁平立克次体和SFG立克次体呈血清阴性。
Antibodies to Ehrlichia canis, Ehrlichia platys, and spotted fever group (SFG) rickettsiae were detected by indirect immunofluorescence in sera from 27 ill individually owned thrombocytopenic dogs (platelet concentrations less than 200,000 platelets/microliters) and 59 healthy kenneled dogs located in southern Louisiana. Platelet concentrations less than 100,000 platelets/microliters were detected in 63% of ill thrombocytopenic dogs and 6.8% of healthy kennel dogs. One ill thrombocytopenic dog had intracytoplasmic E platys morulae detected within platelets. The prevalence of increased serum antibody titers to E canis and E platys was 25.9% and 40.7% for the ill thrombocytopenic dogs and 20.3% and 54.2% for the healthy kennel dogs, respectively. All dogs with seropositivity to E canis had increased antibody titers of greater than or equal to 1:100 to E platys. Simultaneous examination of increased serum antibody titers (greater than or equal to 1:64) to four SFG rickettsiae indicate that Rickettsia rhipicephali and Rickettsia montana accounted for the majority of the antibodies detected in these dogs. Of 86 dogs tested, 44.2% were seronegative to E canis, E platys, and SFG rickettsiae.
