Overview

This research investigates microbial contamination in drinking water systems, highlighting significant health risks for livestock.

Key Points

  • This study aims to analyze the microbial composition of biofilms in drinking water systems for broiler and piglet production and their effects on water quality.
  • Collected biofilm swabs from water lines before cleaning and disinfection.
  • Evaluated bacterial load with total aerobic count.
  • Identified bacterial taxa using 16S gene metabarcoding.
  • Compared microbial communities in broiler houses and pig nursery units.
  • No significant differences in microbial load; median total aerobic count was 3.6 log CFU/cm2.
  • Enterococci were detected in 80% of samples; E. coli was more frequent in broiler houses (47%) than in pig units (27%).
  • Dominant genera included Staphylococcus and Pseudomonas, with S. saprophyticus as the most common isolate.
  • Similar bacterial taxa were found in both drinking water and biofilms, indicating contamination risks.
