Natural Exposure

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.

To determine the tick species that bite humans in the province of Soria (Spain) and ascertain the tick-borne pathogens that threaten people's health in that province, 185 tick specimens were collected from 179 patients who sought medical advice at health-care centres. The ticks were identified, and their DNA examined by PCR for pathogens. Most ticks were collected in autumn and spring (59 and 57 respectively). Nine species of ticks were identified, the most frequent being Dermacentor marginatus (55·7%), Ixodes ricinus (12·4%) and Rhipicephalus bursa (11·9%). Ninety-seven females, 66 males, 21 nymphs and one larva were identified. Twenty-six ticks carried DNA from Rickettsia spp. (11 Rickettsia slovaca, 6 Rickettsia spp. RpA4/DnS14, 1 Rickettsia massiliae/Bar29, and 8 unidentified); two ticks carried DNA from Borrelia burgdorferi sensu lato and seven ticks harboured DNA from Anaplasma phagocytophilum.

AbstractThe capability of imidacloprid 10% + flumethrin 4.5% (Seresto®) collars to prevent transmission of Borrelia burgdorferi sensu lato (Bbsl) and Anaplasma phagocytophilum (Ap) by naturally infected ticks was evaluated in two studies with 44 dogs. In each study, one group served as non-treated control, whereas the other groups were treated with the Seresto® collar. All dogs were exposed to naturally Bbsl- and Ap-infected hard ticks (Ixodes ricinus, Ixodes scapularis). In study 1, tick infestation was performed on study day (SD) 63 (2 months post-treatment [p.t.]); in study 2, it was performed on SD 32 (one month p.t.) respectively SD 219 (seven months p.t.). In situ tick counts were performed 2 days after infestation. Tick counts and removals followed 6 (study 1) or 5 days (study 2) later. Blood sampling was performed for the detection of specific Bbsl and Ap antibodies and, in study 1, for the documentation of Ap DNA by PCR. Skin biopsies were examined for Bbsl by PCR and culture (only study 1). The efficacy against Ixodes spp. was 100% at all time points. In study 1, two of six non-treated dogs became infected with Bbsl, and four of six tested positive for Ap; none of the treated dogs tested positive for Bbsl or Ap. In study 2, ten of ten non-treated dogs became infected with Bbsl and Ap; none of the treated dogs tested positive for Bbsl or Ap; 100% acaricidal efficacy was shown in both studies. Transmission of Bbsl and Ap was successfully blocked for up to 7 months.

Klinische Relevanz

ZusammenfassungGegenstand: Berner Sennenhunde (BSH) haben häufiger Antikörper gegen Borrelia burgdorferi sensu lato (Bbsl) als andere Hunderassen, aber es ist nicht bekannt, ob dies auch für andere Erreger gilt. Das Ziel dieser Studie war zu untersuchen, ob BSH häufiger und höhere Antikörpertiter gegen Bbsl, Anaplasma phagocytophilum (Ap) und verschiedene Serovare von Leptospira (L.) interrogans zeigen. Material und Methoden: In die Studie wurden 171 BSH und 57 Kontrollhunde eingeschlossen. Als Kontrollgruppe dienten große (< 30 kg), langhaarige Hunde mit dunklem Fell. Alle Blutproben wurden mithilfe eines Zwei-Stufen-Tests (kinetischer computergestützter enzymgekoppelter Immunadsorptionstest [KELA] und Western Blot) auf das Vorliegen spezifischer Antikörper gegen Bbsl, mit einem Immunfluorenzenztest auf die Anwesenheit von spezifischen Antikörpern gegen Ap und mit einem Mikroagglutinationstest auf das Vorliegen spezifischer Antikörper gegen verschiedene Serovare von L. interrogans untersucht. Ergebnisse: BSH wiesen eine signifikant höhere Prävalenz von Antikörpern gegen Bbsl auf als die Kontrollhunde (43,3% vs. 17,5%; p > 0,001). Impfantikörper gegen Bbsl blieben bei der Prävalenzberechnung unberücksichtigt. Bei 50,3% der BSH fanden sich Antikörper gegen Ap, während dies nur bei 24,6% der Kontrollhunde der Fall war (p > 0,001). Für BSH ergab sich dagegen im Vergleich zu den Kontrollhunden keine höhere Prävalenz von Antikörpern gegen alle 18 Serovare von L. interrogans außer gegen L. copenhageni. Schlussfolgerung und klinische Relevanz: BSH zeigten eine höhere Prävalenz von Antikörpern gegen Bbsl und Ap sowie höhere Antikörpertiter gegen Bbsl und Ap. Außerdem wiesen BSH signifikant höhere Antikörpertiter gegen L. canicola (p = 0,003), L. copenhageni (p = 0,005), L. grippothyphosa (p = 0,029) und L. vanderhoedoni (p = 0,035) auf. Die Ursache dafür und eventuelle klinische Auswirkungen sind bisher unbekannt.
