BST MILK and Ordinary MILK Indistinquishable? Not Really.

I wonder why. probably because the systems evolved in a situation where bacteria dominate. So why would the viral one dominate? Sorry for being dense, I was force-fed pasteurised milk as a child Because for a billion years of evolution bacterial challenge was forever dominant. So when you have a see-saw, best to bias it away from the direction it is pushed, I would guess. Sorry, how do you know bacterial challenge was dominant over these years? There is lots of vestigial organelle evidence for viral invasions over the aeons. Certainly in evolutionary terms it's very very recent that man lived in large (say 2000+) closely packed groups with good communication between groups. Within the groups, surely. Ten to 30 k anni? Eh? Which bit? I'm sure the groups competed with little communication between them. Ten to 30 thousand years? I would thus imagine that new viral attacks were very rare (and probably pretty devastating). Well they still are in modern times. Flu and small pox to name just two. They are probably predominant in modern times. Bacterial attack being squashed with antibiotics. Remember a lot of flu (eg 'common cold' and gastroenteritis is viral today. And I'd assumed it was ever thus. I would guess that antibiotics have had close to zero effect on bacteria. Do you know of any that have gone extinct? Typically the local endemic viruses would have all been encountered in childhood. Bacterial challenge, though, would continue throughout life. Well I still get regular (but seldom) colds and flu, how about you? Yes, but I probably get mild bacterial infections of the gut every couple of weeks, and for sure when walking and working in cow slurry I must be getting a substantial bacterial challenge. Remember that a challenge that is 'dealt with' is still a challenge and the immune response is triggered even if no serious (or even observable) illness results. Of course. Same with viri But at least one with relevant sensitivities would be better, if the bacterial infection is routinely expected. This is typically the case in young animals with clinical viral disease. Prophylactic antibiotics for likely bacterial secondary infections. This is what some doctors do for susceptible patients with viral URTIs. They used to do it routinely when I was younger. They have seen the light. I have actually told an older quack that I didn't want his script for antibiotics if all I had was a virus. All I wanted from him was confirmation that I didn't have anything eminently treatable. Oh, and a certificate for work I didn't have you down as a young animal. I certainly was, a long trime ago. Now I'm an old animal. |
