Parasitic Fauna of Domestic Poultry in Armenian Regions Reveal Alarming Infection Rates

A study conducted in the mountainous zone of Armenia has revealed alarming infection rates of domestic poultry with parasitic fauna. The research, published in the journal Ug Rossii: ekologia, razvitie, aimed to study the parasitic fauna of domestic poultry in the Gegharkunik and Tavush regions of Armenia. The study collected samples from 2022 to 2023, examining a total of 107 bird feces and 130 mollusks.

Key Takeaways:

  • The study identified 3 species of nematodes, 1 species of trematodes, and 1 species of protozoa infecting domestic poultry, including chickens, turkeys, and geese.
  • Mixed invasions of helminths and protozoa were identified in all birds, with the degree of invasion varying among species.
  • Eimeria, a type of protozoa, was found in all examined birds, with infection rates ranging from 36% to 100%.
  • The highest extent of helminthic invasion was recorded in Nematodosis, reaching up to 86%, with Ascariasis exhibiting low rates of invasion intensity.
  • The study stresses the importance of timely detection and study of helminth spread in poultry to maintain poultry health, productivity, and high-quality production.

Statistics:

  • 107 bird feces samples were examined in the study.
  • 130 mollusks of the species Lymnaea stagnalis were examined.
  • 3 species of nematodes were identified: Ascaridia galli, Capillaria obsignata, and Singamus trachea.
  • 1 species of trematodes was identified: Echinostoma revolutum.
  • 1 species of protozoa was identified: Eimeria.
  • Eimeria infection rate ranged from 36% to 100%.
  • Nematodosis exhibited the highest extent of helminthic invasion, reaching up to 86%.
  • Ascariasis showed low rates of invasion intensity.
