Zur Bedeutung von Rotavirus‐Infektionen beim Hund

Zusammenfassung Bei 17 (1,75%) von 973 Kot- und Darmproben enteritisch erkrankter Hunde lies sich mittels ELISA Rotavirusantigen nachweisen, ebenso bei 2 von 30 Kontrolltieren. Beim Hund scheint das Rotavirus daher nicht die gleiche Bedeutung als typischer Enteritiserreger zu besitzen wie bei anderen Tierspezies oder beim Menschen. Der Anteil von 84% positiven Serumproben unter 300 Hunden (Nachweis von Rotavirus-Antikorpern im ELISA) spricht andererseits fur eine starke (klinisch inapparente?) Durchseuchung der Hundepopulation. Ob und in welchem Mase daran u.U. andere als originar canine Rotaviren beteiligt sind, lies sich durch die Untersuchungen nicht klaren. Summary Significance of rotavirus infections in dogs Rotavirus antigen was detected by ELISA in 17 (1.75%) of 973 faecal and intestinal samples from dogs with enteritis, and in two of 30 control animals. In contrast to other species including man, rotavirus obviously is not a typical aetiological agent of enteritic diseases in the dog. On the other hand, the rate of 84% seropositive dogs (demonstration of antibodies by ELISA) speaks in favour of a widespread occurrence of rotavirus infections (possibly inapparent) also in this species. It has to be clarified whether and to what degree other than canine rotaviruses are involved. Resume Signification des infections a Rotavirus chez le chien Un antigene Rotavirus a ete mis en evidence au moyen de l'ELISA dans 17 (1,75%) sur 973 echantillons de matieres fecales et d'intestin de chiens souffrant d'enterite et chez 2 des 30 animaux de controle. Rotavirus ne semble pas avoir la meme signification chez le chien que chez d'autres especes animales ou chez l'etre humain en tant qu'agent typique d'enterite. Le 84% des serums positifs parmi 300 chiens (mise en evidence des anticorps Rotavirus avec ELISA) indique par ailleurs une forte contamination (cliniquement inapparente?) de la population canine. Les recherches n'ont pas permis d'expliquer dans quelle mesure d'autres Rotavirus que ceux d'origine canine intervenaient. Resumen La significacion de infecciones por rotavirus en el perro En 17 (1,75%) entre 973 muestras de heces e intestinos de perros enfermos de enteritis se pudo poner en evidencia antigeno de rotavirus a igual que en 2 de 30 animales testigos, mediante el procedimiento ELISA. Por lo tanto, parece ser que en el perro no tiene la misma significacion como agente etiologico tipico de enteritis que en otras especies animales o en el ser humano. Por el contrario, la cuota de un 84% de muestras de suero positivas entre 300 perros (puesta en evidencia de anticuerpos de rotavirus en el ELISA) aboga a favor de una morbilidad considerable (?clinicamente inaparente?) de la poblacion canina. Por medio de esta pesquisa no se pudo aclarar si y en que grado, si se presenta la ocasion, se hallan envueltos otros rotavirus que no sean los caninos originarios.
