Researchers optimized bacteriophage (phage) isolation from cattle, successfully recovering 83 phages targeting common bacteria. This advancement aids in studying cattle microbial communities but requires further refinement for isolating phages against specific bovine pathogens.

Area of Science:

  • Microbiology
  • Veterinary Science
  • Genomics

Background:

  • Bacteriophages (phages) are crucial for microbial community research in cattle.
  • Phage isolation is hindered by host specificity and diverse microbial ecosystems.
  • Optimized screening methods are needed for efficient phage recovery from cattle.

Purpose of the Study:

  • To optimize phage-screening methods for various cattle body sites.
  • To isolate lytic phages targeting bovine pathogens and commensal bacteria.
  • To characterize isolated phages and their bacterial hosts.

Main Methods:

  • Screened 1214 cattle and environmental samples using 13 phage detection methods.
  • Employed one high-throughput screening approach.
  • Isolated and identified phages and their inhibited bacterial genera.

Main Results:

  • Isolated 83 phages, predominantly from ruminal fluid and feces.
  • Identified bacterial hosts from 29 genera, with Bacillus and Escherichia/Shigella being most common.
  • Method 12 showed highest phage recovery efficiency, especially from ruminal samples.

Conclusions:

  • Optimized screening methods successfully recovered bacteriophages from diverse cattle-associated microbial ecosystems.
  • Phages were recovered from gastrointestinal, reproductive, respiratory, and fetal bovine samples.
  • Further research is needed to enhance recovery of phages targeting specific bovine pathogens.
