Tiddles seemed fine in himself, just a normal kitten but a bit lethargic at times and the only symptoms the others had was an occasional sneeze. Never would I have thought that Tiddles had E-coli, you need your vet to do tests as mine didn't think he had any infection at first until I took him back a couple of days later and decided to do swab tests. I'm just saying I don't know what it is, but isn't it better to be safe than sorry? We could have lost Tiddles, over a couple of sneezes a day - the antibiotics are a danger to him as he is so young too, but we are doing everything possible.
