Short communication The first finding of antibodies to Encephalitozoon cuniculi in cows in Slovakia

The presence of antibodies against Encephalitozoon cuniculi in cows was observed by the method of indirect immunofluorescence (IFAT). The animals reacting at the titre 1 : 64 and more were considered positive. Of the total number of 55 sera examined, 20 were positive at the titre 1 : 64, from which four were positive at the titre 1 : 256 also. Our results indicate that it is very important to carry out screening examinations in large-scale breeding of cattle due to the persistent high percentage of bovine abortions and disorders in the reproductive cycle of unknown etiology. # 1999 Elsevier Science B.V.
