A reader ask this question “If I have no lactobacillus, and most lactobacillus probiotics are not human source (so will not stay around), is there any hope to recover lactobacillus?”.  Looking at the data I found on 343 samples only 15 samples has no measurable lactobacillus. If the number is very low, ubiome will report it as none.

Those with subsequent ubiomes with lactobacillus.

Some Examples:

• AC:
  • Original: null
  • 2014: 772
  • 2015 1819
• AK
  • 2017-08: null
  • 2017-12: 52
• TK
  • 2016-02: null
  • 2017-01: 936
  • 2017-03: 108
  • 2017-09: 1996

One reader had them wrapped out, I assume due to antibiotics or other prescription drugs.

• 2018-03: 128092
• 2018-05: null

Bottom Line

There appears to be evidence that Lactobacillus will repopulate over time.
