There are intermediate hosts and we dont know their identity yet are native bots and nothing to do with us. Just warns against taking nest boxes down out of fear bats are vital for our ecosystem in areas like pest control in 2007 together with a virologist Christian Thorsten flora and lots of house carried out a study on the bats in the cult back caves in a bag they found coronavirus in the bats there but a harmless ferocity. And as there were lots of a very high natural diversity of coronaviruses its not just the sars like coronaviruses but also a range of others too and corona viruses are not restricted to bats they exist in many mammals they even found the corona virus in a palooka whale. Its not just mammals fish to. An opposition. The friedrich lefler institute on the island of reims is researching which animals carry the virus that is currently causing so much anxiety around the world. Their work takes place under high security. So far cats dogs and minx have become infected naturally now just recently it happened in to make farms in the netherlands. Have also been experimental infections of ferrets in hamsters and rob its pretty bad i. Think it is the. Parents are playing their part in developing a vaccine against the corona virus farm animals like pigs have so far not become infected they appear to be not susceptible to the virus but even animals that have the corona virus do not necessarily infect people some fear with pets for example. That you thought of the animals which have so far tested positive are associated with the sars coronavirus to infection or a cold with 19 illness in people that means we believe it was human to animal transmission. There is no epidemiological evidence anywhere in the world that animals be they wild animals farm animals or domestic pets play any kind of epidemiological role in the spread of the pathogen these animals are not identified as risk factors the pandemic thrives on direct human to human transmission. They can manage to manage. Anyone who is sick with coburg 19 should avoid close contact with pets so as not to infect them but which animal originally transmitted the virus to humans possible candidates are the rakuten dog the pangolin and the civet. But so far there are only indications not Firm Evidence florian gloats of house hopes that there will be certainty soon meanwhile the knocked center has reopened and just planning an exhibition on parts of the virus to explain why no one has to be too afraid of the nocturnal creatures. We have someone here with us to explain a bit more professor to west who weve just seen in this report he of course is a rather just and the president of the institute thats the federal Research Institute for Animal Health here in germany good to have you with us and youve been doing research on a covert 1000 vaccine using ferrets what are you finding so far. Hello from insole riggs i mean 1st of all i have to do the animal model and for testing that seems to be used in humans afterwards the animal model needs to mimic the human situation as closely as possible and we find in ferrets that are susceptible to replicate and multiplied a virus takes created and they can transmitted by they dont get sick so they are a model of asymptomatic infections that it still lead to infectious change in contrast to for example harms that pastors that get sick in our 1st serious of experiments we tested 3 different essays i mean one was an infection we did lead to an immunity which is solid enough to prevent a 2nd infection and at least in the short run we can say yes that is the case saw ferrets that recover from the 1st infection they have a solid immunity and they completely resist a 2nd infection after he became. We tested them in a debate that theyve seen preparation which didnt really work very well and we have then tested one of the candidate big scenes which is a big debate scene that we tested which has been developed by didnt Maximillian University community i cant tell you about the final resolved yet but there are some promising results are showing that its all still work in process but it sounds very promising already whats interesting though is i mean we saw this in a report as well that paid such as cats dogs they can catch the virus at knife stock seems to be immune what does this tell us about the virus and how it chooses its host. It is an interesting question there are many scientists for bio actually chasing at there is a lot of molecular modeling going on in trying to predict which animal species could be susceptible to the virus and bits not just as more or less a lock and key principle that is used by viruses to enter cells were and organisms but unfortunately this doesnt really match that well so for example for pigs there was the idea that there would be a good effect of all susceptible to virus and if youre really infect them in real life theyre proved to be resistant so i think for the time being were still have to really believe in vitro modeling data by infecting the real organism and the results could be quite different now of course especially now in times of a pandemic when we talk about viruses we talk about something bad something we must fight but we mustnt forget the viruses also play an Important Role for our ecosystem and certainly dont harm bats as we flew and is there such a thing such as a good virus and a bad virus. I mean any viruses good and bad is more i mean what you do to us as humans so whether we have a direct or indirect harm done we say they are bad and if we dont feel anything there might be good i mean viruses are the most prevalent lifeform on this planet they have the highest rate of biodiversity or genetic diversity dont we know and viruses are at the basis of life as we know it or at least virus like elements and without viruses we would actually not be here they are the major drivers of nutrient turn over for example india in the oceans so for all just as myself just fascinating tiny little tiny been beings as predicted after i called them and they are most fascinating organisms to study very well professor let me lie to covert 19 weve heard that many times now isnt the 1st soul knows this a probably isnt the last what can we learn from this one. Its definitely not the last one and in fact i mean all scientists have been saying there will be another pandemic and for all we dont know where and when and which agent infectious agent would be involved what we can learn from this one here is we will probably never be able to prevent rejections from animals to humans because humans are we are biologically part of the Animal Kingdom so this is just a continuum there on the other hand what we need to be alert on has the 1st infection chains that develop so if the new agent that enters the human population learns to be transmitted efficiently from human to human these are then all local epidemics and we need to find them and detect them arrest early as possible and then also do their controlled infection at this very early stage where we can improve or at i think i would ill stick procedures are specific and sensitive enough to detect these events but we have to be on the alert ok a professor i met in leiter thank you so much for your time and to stay healthy as always you are a common yourself as well. Well time for your questions now and that means over to our science correspondent derrick williams. What is the size of the coronavirus in microphones. With all of these large scale animations of coronaviruses that i look at every day sometimes its hard to remember how tiny they actually are to answer this question lets 1st get the terms down micron is an old way to say micro meter which is one millionth of a meter to put that maybe in terms that we can visualize it takes a 1000 micro metres to make a single millimeter now this small ones that is a virus is much smaller its down in whats called the nanometer range a 1000 nanometers makes up a single microcontroller at around 125. 00 nanometers in diameter source code 2 is actually a pretty large virus at least among the viruses that in fact humans but it would still take 8 of them lined up to stretch a single micro metre or micron if you prefer. Hair is always used to illustrate stuff like this a human hair is around 50 microns across so it would take around 400. 00 coronaviruses end to end just a span the width of a human hair you know a triple checked my mouth on this one but it isnt really my strong suit i hope i got it right im sure that somebody will tell me if i did. And thats all for this edition of 900 special today we want to leave you with beautiful images of very happy dolphins off the coast of south california thanks for watching. The fun.

With me to start september 16th. Or you hijacking the news. Where i come from the news is being hijacked journalism itself has become a scripted reality show its not just good versus evil us versus them black and white. In countries like russia china churchy people are told lives thats nothing and if youre a journalist here and you try to get beyond it you are facing scare tactics intimidation. And i wonder is that where were headed as well. My responsibility. As a journalist is to give me all of the smoke and mirrors its not just about the prayer for a barrel it or being neutral its about being true. When he was born golf and i were getting up.
