Key messages

  • One study evaluated the effects of treating bats with a probiotic bacterium to reduce white-nose syndrome infection. The study was in Canada.

COMMUNITY RESPONSE (0 STUDIES)

POPULATION RESPONSE (1 STUDY)

  • Survival (1 study): One randomized, replicated, controlled study in Canada found that treating little brown bats with a probiotic bacterium at the time of infection with white-nose syndrome increased survival, but treating bats 21 days prior to infection had no effect.
  • Condition (1 study): One randomized, replicated, controlled study in Canada found that treating little brown bats with a probiotic bacterium at the time of infection with white-nose syndrome reduced the symptoms of the disease, but treating bats 21 days prior to infection made symptoms worse.

About key messages

Key messages provide a descriptive index to studies we have found that test this intervention.

Studies are not directly comparable or of equal value. When making decisions based on this evidence, you should consider factors such as study size, study design, reported metrics and relevance of the study to your situation, rather than simply counting the number of studies that support a particular interpretation.

Supporting evidence from individual studies

  1. A randomized, replicated, controlled study in 2013–2015 in a laboratory in Manitoba, Canada (Cheng et al 2017) found that treating bats with a probiotic bacterium Pseudomonas fluorescens at the time of, but not 21 days prior, to infection with white-nose syndrome reduced symptoms and increased survival. For bats that received the probiotic treatment at the time of white-nose syndrome infection, four of five disease symptoms were significantly lower than for untreated, infected control bats (data reported as statistical model results). For bats that received the treatment 21 days prior to infection, all five symptoms were significantly greater than for untreated, infected control bats. Bats that received the probiotic treatment at the time of infection also had significantly higher survival rates (71% of bats survived after 185 days) than untreated, infected control bats (18% of bats survived). Survival rates between all other treatment groups did not differ significantly. Eighty-five little brown bats Myotis lucifugus were collected from a hibernaculum and equally divided into five treatment groups (probiotic treatment 21 days prior to white-nose syndrome infection, probiotic treatment at time of infection, probiotic treatment only, infection with white-nose syndrome only, no treatment). Bats were monitored for up to 185 days during hibernation.

What Works in Conservation

What Works in Conservation assesses the research looking at whether interventions are beneficial or not. It is based on summarised evidence in synopses, on topics such as amphibians, bats, biodiversity in European farmland, and control of freshwater invasive species. More are available and in progress.
