Since the onset of the corona the crisis appeared over and over again times reports that individual Pets may have been infected with the new Coronavirus Sars-CoV-2. A laboratory study of virologists, and Veterinarians to Bu Zhigao of the Chinese Academy of Agricultural Sciences demonstrates for the first time, that infection is at least in cats, under certain conditions, possible. Their study, however, was not examined yet and for the time being on the bioRxiv uploaded. In the laboratory, the cats have not transmitted the Virus to individual conspecifics, diseased but obviously. It remains unclear whether cats could transmit the virus to people.
researchers injected the virus in the animals samples in nose – Virologist warns us to beware
in Order to infect the animals, had to Zhigao and Co at very strongly: you injected virus samples directly into the noses of five house cats, and studied two animals, six days later. Both had virus RNA and infectious virus in their upper respiratory tract. The three other cats were kept in cages in the direct vicinity of other cats. In one of these animals, the scientists discovered later also virus-RNA. In addition, all four infected cats antibodies against Sars-meadows-CoV-2.
compared To “Nature,” warned the Virologist Linda Saif, the Ohio State University in Wooster for caution in the Interpretation of the study: this was a laboratory study in which animals were deliberately infected with high virus doses. This does not correspond to the normal contact between the holders and your little cats. Only one cat was plugged directly in the case of conspecifics: The not suggesting that the corona viruses spread easily between animals. In addition, it is unclear how the animals were kept and whether the Transfer by droplets, as in the case of humans or about through infectious feces or urine took place. Further Tests with different virus doses are therefore necessary to assess the specific risk of infection.
ferrets are particularly susceptible dogs studied, tend not to
Zhigao and his Team also whether and how the Virus to other animals transfer. Ferrets were according to the results, very easy to plug in. The virus increased relatively strongly in the upper Airways; however, neither the sick, the animals still died of it. Ferrets could therefore act as model animals for vaccine and drug studies, as in the case of influenza analyses will be made, the authors write.
dogs seem a little receptive to the new Coronavirus: five intentionally infected animals eliminated only two viruses-RNA with the feces, in no could be demonstrated replicating virus. The Same was true for experimental purposes, – treated ducks, pigs, and chickens. You retire according to the current state of knowledge, as a Reservoir for Sars-CoV-2 for the time being.
The American center for disease control CDC recommends Covid-19-Concerned, to reduce the contact with your Pets. You should not caress, for the period of the infection, kissing, or food to share with you. This is true, however, for all the new diseases, about which we have too little information.
