| seroprevalence of babesia equi among horses in israel using competitive inhibition elisa and ifa assays. | sera from 361 horses were tested by indirect immunofluorescence antibody test (ifa) and by competitive inhibition elisa (celisa), to detect antibodies to babesia equi. the concordance between the assays was 95.7%. application of a cutoff based on a calculated percent inhibition of < 20% gave a total of 22 discrepant results, while only 8 sera negative by the celisa were found positive by the ifa when a cutoff of > 20% inhibition was used. approximately one-third of all the horses tested were fou ... | 1998 | 9650862 |
| novel description of force of infection and risk factors associated with theileria equi in horses in israel and in the palestinian authority. | the objectives of this study were to determine the force of infection (foi) for theileria equi in horses in israel and to evaluate risk factors associated with seroprevalence a decade after it was last determined by pcr, in 2002. using a commercial celisa kit, we demonstrated a widespread and constant exposure to t. equi in israel (110/216; 50.9%) and the palestinian authority (32/108; 29.6%). owing to the paired samples collected from the same horses approximately one year apart, we were able t ... | 2014 | 24703834 |
| demographic and environmental risk factors for infection by theileria equi in 590 horses in israel. | the prevalence of theileria equi infection as well as the environmental and demographic risk factors for infection was studied in 590 healthy horses from 46 farms in israel. the prevalence of t. equi dna was assessed using a polymerase chain reaction for a segment of the theileria 18s rrna gene. the overall prevalence was 26.4% (156/590). there was a significant geographical variation in the prevalence of t. equi infection, ranging from 9.3% (25/270) in the central lowlands to 81.7% (49/60) in t ... | 2012 | 22293151 |
