“…The seroprevalence of A. phagocytophilum (10.3%) in the present study is consistent with some serological surveys conducted in European countries, such as in northern Bulgaria (12.0%) [26] and France (13.5%) [21]. However, higher infection rates were reported in horses from Denmark (22.3%) [20] or southern Bulgaria (20.0%) [27].…”

“…The SNAP ® 4Dx ® assay was originally developed to detect Ab against A. phagocytophilum, B. burgdorferi s.l., and Ehrlichia spp. (E. canis, E. chaffeensis, and E. ewingii) in dogs but it has also shown useful results in horses [20][21][22]. The assay uses an all-species conjugate and it is not species-specific for animals; moreover, it has been validated for horses, with 100% sensitivity and specificity for the detection of antibodies against A. phagocytophilum and 100% and 95%, respectively, for B. burgdorferi s.l.…”

The purpose of this study was to investigate the seroprevalence of selected tick-borne-pathogens (TBPs) among Romanian horses. For this, a total of 223 animals originating from north, central, and southeast Romania, including horses from stud farms (n = 118) and working horses (n = 105), were tested using a commercial rapid ELISA-based test. Overall, 10.3% (95% confidence interval (CI): 6.7–15.1%) of the tested horses were seropositive for antibodies (Ab) against Anaplasma phagocytophilum. Additionally, 18.8% (95% CI: 13.9–24.6%) and 0.5% (95% CI: 0.01–2.5%) of horses were seropositive for Ab against Borrelia burgdorferi sensu lato and Ehrlichia spp., respectively. Among the tested horses, 3.1% were seroreactive to two or three pathogens. These findings show the natural exposure of Romanian horses to zoonotic tick-borne pathogens and emphasize the need for further studies to better understand the epidemiology of equine tick-borne diseases in Romania.

SUMMARYThe aims of this study were to determine the seroprevalence of Ehrlichia spp. and risk factors for exposure in a restricted population of dogs, horses, and humans highly exposed to tick bites in a Brazilian rural settlement using a commercial ELISA rapid test and two indirect immunofluorescent assays (IFA) with E. canis and E. chaffeensis crude antigens. Serum samples from 132 dogs, 16 horses and 100 humans were used. Fifty-six out of 132 (42.4%) dogs were seropositive for E. canis. Dogs > one year were more likely to be seropositive for E. canis than dogs ≤ one year (p = 0.0051). Ten/16 (62.5%) and 8/16 (50%) horses were seropositive by the commercial ELISA and IFA, respectively. Five out of 100 (5%) humans were seropositive for E. canis and E. chaffeensis. Rhipicephalus sanguineus (n = 291, 97.98%) on dogs and Amblyomma cajennense (n = 25, 96.15%) on horses were the most common ticks found. In conclusion, anti-Ehrlichia spp. antibodies were found in horses; however, the lack of a molecular characterization precludes any conclusion regarding the agent involved. Additionally, the higher seroprevalence of E. canis in dogs and the evidence of anti-Ehrlichia spp. antibodies in humans suggest that human cases of ehrlichiosis in Brazil might be caused by E. canis, or other closely related species.

“…In this study we determined the seroprevalence rate as 8.57% which is lower than France (11.3%) [33] , Guatemela (13%) [34] , Sweden (16.6%) [35] , Italy (17.03%) [36] , Denmark (22.3%) [37] , Tunus (16.3-67%) [15,38] , USA (17-29%) [39] , and Czech Republic (73%) [40] , and higher than Korea (2.9%) [41] , Sub-Saharan Africa (0%) [42] , Taiwan (2.5%) [43] , and Japan (3.4%) [44] . Our result was found to be approximately equal with the studies conducted in Italy (8.9-9%) [45,46] .…”

Anaplasma phagocytophilum, the causative agent of equine granulocytic anaplasmosis, affects several species of wild and domesticated mammals, including horse, besides human. In Turkey, there were many reports on A. phagocytophilum circulation among cattles, sheep, dogs, mice, humans, except horses. In this study, we aimed to inquiry whether A. phagocytophilum were circulating among the horse population or not. For this purpose, 105 mare horse blood sera were examined for the presence of Anti-Anaplasma phagocytophilum IgG antibodies by IFAT. The seroprevalance rate of 8.57% horse sera were found to be positive. This was the first report about the presence of anti-A. phagocytophilum antibodies in horses in Turkey..
