I want to share my experience of my 2.5 year old son having e-coli 0157. In January 2019 my son started to have what can only be described as continuous diarrhea, like dysentery. As it was so severe we took him to the GP who asked us to provide a stool sample. We did this and though he continued to have diarrhea he seemed to be improving so we almost forgot about the stool sample until a week later we get a phone call from our GP saying that he has tested positive for e-coli 0157. This is the very serious one, not to be confused with the e-coli we already have in our stomachs. This can cause serious kidney failure if it jumps from the intestine to the bloodstream through something called HUS and possible death. Therefore our case was handed to Public Health England. PHE took over and we were asked a million questions, we had not been to a petting zoo or a farm and didn't remember eating undercooked meat as we are mostly vegetarian. Anyway - our son was getting worse again and panic set in, visits to hospital for blood tests etc. We were told it should last max 10 days, however a month later he was still testing positive. He had lost a lot of weight and by now both him and his sister had been forcibly signed off school, hugely frustrating as his sister was not sick. Suddenly I was at home with 2 kids full time and couldn't work. Nursery wouldn't give us a refund so we were paying for time he wasn't there. It was starting to become a nightmare. Our son seemed much better but still was testing positive. Then, I did some research, as there is no clinical treatment for e-coli 0157 I was determined to find if anything else would help. Information I gathered told me that I should be giving him Lactobacillus Casei strain of pro biotic, which I bought in tablet form for him from Wholefoods, gave him 2 per day, plus 3 x yakult drinks per day, Bio-Kult Infantitis and Kombucha drinks mixed with concentrated cranberry juice. Amazingly within 2 weeks he was testing negative for e-coli 0157. At toddler age they can take 18 months to test negative so everyone at PHE and the council were thrilled. I am writing this post to help others, to save them having to take so much time off work as i did and lose so much money as I did in the hope it can be helpful. The good bugs (those exact ones) pushed out the bad bugs it seemed !
