A total of 374 dogs, 252 from five military kennels and 122 privately owned, were tested for Ehrlichia canis antibody. Sera were tested at a 1:20 dilution by indirect fluorescent antibody with the use of E. canis cell-culture antigen slides. The overall prevalence of E. canis antibody was 33%. Antibody prevalence among military dogs (29%) was significantly lower than among privately owned dogs (41%; P < 0.05). The E. canis seroprevalence among dogs infested with ticks (Rhipicephalus sanguineus) was higher (44%) than that among uninfested dogs (31%; P = 0.08). The seroprevalence among military dogs varied from 21-46% at the five kennels; lower prevalences were observed in kennels with higher sanitary and hygienic conditions. Age- and sex-related E. canis antibody prevalences were not significantly different among military and privately owned dogs, although adult and male privately owned dogs had the highest seroprevalences (45% and 44%, respectively). Three dogs with epistaxis had E. canis antibody titres > 1:320. These data demonstrate the first laboratory evidence of E. canis infection among dogs in Egypt.
总共对374只狗进行了犬埃立克体抗体检测，其中252只来自五个军事犬舍，122只为私人饲养。血清以1:20的稀释度通过间接荧光抗体法检测，使用犬埃立克体细胞培养抗原玻片。犬埃立克体抗体的总体患病率为33%。军犬中的抗体患病率（29%）显著低于私人饲养犬（41%；P<0.05）。感染蜱（血红扇头蜱）的犬中犬埃立克体血清阳性率（44%）高于未感染蜱的犬（31%；P = 0.08）。五个犬舍中军犬的血清阳性率在21%-46%之间；在卫生条件较好的犬舍中观察到较低的阳性率。军犬和私人饲养犬中与年龄和性别相关的犬埃立克体抗体阳性率没有显著差异，尽管成年和雄性私人饲养犬的血清阳性率最高（分别为45%和44%）。三只鼻出血的狗的犬埃立克体抗体滴度>1:320。这些数据证明了埃及犬中犬埃立克体感染的首个实验室证据。
