Propagation of bovine rotavirus by young dogs

Abstract

Ten young dogs were experimentally infected twice with different isolates of bovine rotavirus and 2 uninfected dogs were kept in contact with them. None of the animals developed diarrhoea, but all of them excreted rotavirus in their faeces over a period of up to 10 days after each inoculation, as shown by counterimmunoelectro-osmophoresis and virus isolation. Dogs may thus play a role in the epizootiology of rotavirus diarrhoea in calves. Seroconversion occurred in 6 of the 10 infected dogs but in neither of the 2 contact controls.

Avian-to-Mammal Transmission of an Avian Rotavirus: Analysis of Its Pathogenicity in a Heterologous Mouse Model

“…There have been no experimental studies on infection of avian rotaviruses in mammalian species. On the other hand, interspecies infection of mammalian rotaviruses has been studied in several animals, including dogs (Schwers et al, 1983), calves (Castrucci et al, 1984), rats (Guerin-Danan et al, 1998), rabbits (Castrucci et al, 1984;Ciarlet et al, 1998aCiarlet et al, ,b, 2000Conner et al, 1988), and mice (Bell et al, 1987;Offit et al, 1984;Ramig, 1988). Among animal models, the physiopathology of rotaviruses in rabbit and mouse models is the most well understood since these models have been most often used.…”

Rotaviral and Coronaviral Diarrhea

“…53 On the other hand, although the calf rotavirus has been demonstrated not to be pathogenic for humans, nor for a variety of laboratory animals, some strains are pathogenic for piglets 27 and can infect young dogs, resulting in virus shedding but not diarrhea. 70 Recent evidence suggests that the NCDV strain of calf rotavirus appears to offer some possibilities as a potential human vaccine strain for the prevention of human rotaviral diarrhea. 85 Calf rotaviruses have been isolated from numerous countries around the world, and their distribution appears to be ubiquitous.…”

Rotavirus infections in domestic animals

“…However, as the algorithm for creation of new viral epitopes relates mal host (Bridger et al, 1975;Tzipori, 1976;Tzipori and Makin, 1978;Tzipori et al, 1980). Cross-species challenge studies in a large number of animal species have shown the ease of the virus in cross-infecting various animal species (Schwers et al, 1983;El-Attar et al, 2001;Mori et al, 2001;Chege et al, 2005). These studies have also demonstrated that challenged animals excreted the virus for a long period, thus acting as potential reservoirs of infection for other animals and humans.…”
