Identifying host sources of fecal pollution: Diversity of Escherichia coli in confined dairy and swine production system

Article Abstract:

Repetitive extargenic palindromic PCR fingerprinting of Escherichia coli is one microbial source tracking approach for identifying the host source origin of fecal pollution in aquatic system. The diversity of Escherichia coli pollutions in manure slurry storage facilities is significant and likely is problematic with respect to library construction for microbial source tracking applications.

Impact of food supplementation with antimicrobial agents on growth performance of broiler chickens, Clostridium perfringens and Enterococcus counts, and antibiotic resistance phenotypes and distribution of antimicrobial resistance determinants in Escherichia coli isolates

Article Abstract:

The effects of feed supplementation with the approved antimicrobial antimicrobial agents are evaluated for the incidence and distribution of antibiotic resistance in some Escherichia coli isolates from broiler chickens. All isolates showed some degree of multiple antibiotic resistance.

Temporal dynamics and impact of manure storage on antibiotic resistance patterns and population structure of Escherichia coli isolates from a commercial swine farm

Article Abstract:

The article presents a comparative study of the temporal dynamics, antibiotic resistance patterns and population structure of the Escherichia coli isolates obtained from fresh feces and manure-holding tanks in a commercial swine farm.
