Overview

John R. Barta is affiliated with the University of Guelph in Canada and has contributed to research primarily in agricultural and biological sciences, immunology and microbiology, and veterinary fields. Their work spans several subfields, including animal science and zoology, parasitology, small animals, ecology, and molecular biology.

Their research portfolio includes a strong focus on coccidia and coccidiosis, parasitic infections and diagnostics, helminth infection and control, animal nutrition and physiology, and veterinary medicine and infectious diseases, as well as vector-borne infectious diseases.

Frequently published in venues such as Poultry Science and the Journal of Parasitology, Barta's works also appear in Veterinary Parasitology Regional Studies and Reports, Frontiers in Veterinary Science, and Parasitology Research.

Recent papers highlight various aspects of parasitology and poultry science. Titles include:

  • Monitoring coccidia in commercial broiler chicken flocks in Ontario: comparing oocyst cycling patterns in flocks using anticoccidial medications or live vaccination (2020, Poultry Science)
  • Exploiting digital droplet PCR and Next Generation Sequencing technologies to determine the relative abundance of individual Eimeria species in a DNA sample (2021, Veterinary Parasitology)
  • Multilocus sequencing of Hepatozoon cf. griseisciuri infections in Ontario eastern gray squirrels (Sciurus carolinensis) uncovers two genotypically distinct sympatric parasite species (2020, Parasitology Research)
  • Restoration of anticoccidial sensitivity to a commercial broiler chicken facility in Canada (2020, Poultry Science)
  • Standardized ileal digestibility of amino acids in broiler chickens fed single or mixture of feed ingredients-based diets with or without Eimeria challenge (2022, Poultry Science)

Barta has co-authored works frequently with several collaborators, including P.S. Kruth, Ryan P. Snyder, Alexandre N. Léveillé, Jessica L. Rotolo, and Billy M. Hargis.
