Leukocyte Culture

Strong, primary mixed leukocyte culture-proliferative responses in certain K region-incompatible strain combinations led us to consider whether an I region-like locus might exist between K and I-A. Results obtained with an (A. TL X B10.D2)F1 anti-B10.BR serum provided serological evidence for a new locus; B10.T(6R)-absorbed serum retained reactivity on AQR lymphocytes. This finding demonstrates an antigen, Ia.W41, encoded by a locus, Ia-7, within a new I subregion, I-N.

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.

In order to evaluate the seroconversion of horses to Babesia caballi and B. canis in Hungary, blood samples were collected from 371 animals on 23 different locations of the country. The presence of antibodies to B. caballi was screened with a competitive ELISA. All 29 positive samples came from one region (the Hortobágy). The prevalence of infection did not show correlation with sexes, and reached 100% in the age group of 2–5 years. Babesia canis -specific antibodies were demonstrated by IFAT in 6.74% of animals kept in 7 regions. The titres were low or medium level (1:40 to 1:160), indicating that the horses had previously been exposed to this piroplasm, but their infection must have been limited. The highest seropositivity rate was observed in the age group of 3–4 years, and males (stallions and geldings) were significantly more frequently infected than females. However, neither B. caballi nor B. canis could be identified in the peripheral blood samples of infected horses by PCR. Since most of the B. caballi -positive horses remained negative in the B. canis IFAT, whereas seroconversion solely to B. canis was detected in several regions of the country, serological cross-reaction between the two species can be discounted. This is the first serological evidence of horses being naturally infected with B. canis , supporting the view that piroplasms are less host specific than previously thought.
