Is It Possible to Get a Lactobacillus UTI?
Lactobacilli are often touted for their beneficial role — but recent research shows that it’s possible to get a Lactobacillus-related UTI. In particular, there have been three case reports about this situation, two for male patients and one for a female patient.4, 6
Researchers point out that Lactobacillus UTIs are exceedingly rare. They mostly appear in patients with immunocompromising conditions (such as HIV), dental complications, or gastrointestinal problems.4
Fortunately, the three patients recovered well after taking specific medications to combat the overgrowth of lactobacilli. Yet, their case reports have been useful for identifying at least seven pathogenic (harmful) lactobacilli:6
- L. acidophilus
- L. gasseri
- L. casei
- L. paracasei
- L. rhamnosus
- L. delbrueckii
- L. plantarum
Treatment of Lactobacillus UTI
Due to the low prevalence of Lactobacillus-related UTIs, experts haven’t been able to identify a standard treatment. The most effective Lactobacillus UTI treatment seems to be antimicrobials, which help combat the excess bacteria in your urogenital tract. These may include:4, 6
Depending on your flora's reaction to antimicrobials, your doctor may prescribe other medications or lifestyle changes. In general, Lactobacillus UTIs resolve in about two weeks with no further complications for the patient.4, 6
Lactobacillus is one of the most important bacteria for your vaginal flora, helping you keep your urogenital tract healthy and free of pathogens. This means it’s completely normal to find Lactobacillus species in urine.
There have been cases of Lactobacillus-related UTIs, but they are very uncommon and cause no severe consequences after treatment. Nevertheless, if you’re in doubt about your urine Lactobacillus levels, make sure to check with a doctor.
