Lactobacillus: no growth in stool sample despite lots of supplements given

[anotherdayanothersquabble]

Any ideas why the lactobacillus I am putting in, is not colonising?

I was suppose ting with 8bn bacteria for three months before the sample was taken, stopped 2 weeks before to test colonisation. Have been taking probiotics on and off for 8 years. Biocare, Biocult and Hyperbiotics.

It was a private stool sample, analysed by Genova Diagnostics. There was colonisations of Haemolytic Escherichia coli, Baccillus species and gamma haemolytic Streptococcus which we will start to treat.

Could these additional bacteria be preventing the growth of the lactobacillus? Any other thoughts as to why they are not sticking?

Ah, sorry, Fatima, I misunderstood.

Has a lactose intolerance been considered btw?

No problem Pacific. I work in Microbiology and was obviously feeling a bit puzzled/sarcastic last night which didn't come across in my post

Au contraire, your sarcasm was clearly detected. Thanks again for your input.

It wasn't just sarcasm, it was a genuine confusion of what you were doing to treat normal commensal gut microorganisms and why
