Summary
Objective: Bovine piroplasmoses are tick-borne protozoan diseases caused by parasites of the genus Theileria and Babesia. The aim of this work was to study the epizootic situation of babesiosis in the cattle population in eastern Poland and possibly to determine which species of protozoa infects Polish cattle. Material, methods and results: Blood samples for molecular analysis (real time PCR) were collected from 192 dairy cattle from various farms located in eastern Poland. The infection was detected in 10.4 % of the samples. All animals were infected with Babesia occultans which sequence of the 18S RNA gene fragment showed a 92.8 % homology with the sequence of B. occultans EU 376017. Conclusion and clinical relevance: This is the first report about the detection of B. occultans DNA in asymptomatic cattle in eastern Poland. The results obtained indicate that the range of these parasites is increasing and that continuous monitoring of babesiosis in cattle in Europe and in Poland is necessary.
Zusammenfassung
Gegenstand und Ziel: Rinderpiroplasmosen sind zeckenübertragene Protozoenkrankheiten, die durch Parasiten der Gattung Theileria und Babesia ausgelöst werden. Ziel der Studie war eine Untersuchung der epizootischen Situation zur Babesiose im Rinderbestand in Polen sowie, falls möglich, eine Bestimmung der den polnischen Viehbestand befallenden Protozoenspezies. Material, Methoden und Ergebnisse: Für eine Molekularanalyse (Echtzeit-PCR-Analyse) wurden Blutproben von 192 Milchkühen aus verschiedenen landwirtschaftlichen Betrieben in Ostpolen gesammelt. Eine Infektion ließ sich in 10,4 % der Proben nachweisen. Alle betroffenen Tiere waren mit Babesia occultans infiziert, wobei die Sequenz des Genabschnitts 18S RNA zu 92,8 % eine Homologie mit der entsprechenden Sequenz von B. occultans EU 376017 aufwies. Es handelt sich hierbei um den ersten Bericht über einen Nachweis von B.-occultans-DNA bei asymptomatischen Rindern in Ostpolen. Schlussfolgerung und klinische Relevanz: Die Ergebnisse deuten darauf hin, dass sich das Spektrum dieser Parasiten vergrößert und dass eine kontinuierliche Überwachung des Vieh bestands in Europa und in Polen im Hinblick auf Babesiose notwendig ist.
