A pathologic study of wild turkeys in Connecticut

Area of Science:

• Wildlife Health
• Avian Parasitology
• Veterinary Pathology

Background:

• Wild turkey populations are vital to ecosystems.
• Understanding their health is crucial for conservation.
• Previous health data for Connecticut's wild turkeys was limited.

Purpose of the Study:

• To establish a comprehensive health profile of wild turkeys in Connecticut.
• To identify prevalent endoparasites and infectious agents.
• To assess the potential impact of parasites on wild turkey health.

Main Methods:

• Examination of viscera from 300 hunter-killed wild turkeys.
• Analysis of blood and serum samples from 19 live-trapped wild turkeys.
• Testing for endoparasites, hemoprotozoa, bacterial/viral agents, and Mycoplasma species.

Main Results:

• Seven endoparasite species were identified in 75% of birds, with Ascaridia dissimilis (52%) and Metroliasthes lucida (37%) being most common.
• High parasite intensity did not correlate with lesions or weight changes.
• Prevalence of potentially pathogenic parasites (Syngamus trachea, Heterakis gallinarum, Capillaria, Eimeria) was low (<3%).
• No hemoprotozoa, common bacterial/viral antibodies, or Mycoplasma species were detected.

Conclusions:

• Connecticut's wild turkey population shows minimal evidence of common infectious diseases.
• Potentially pathogenic parasites are present at very low levels.
• The overall health of the surveyed wild turkey population appears robust.
