Bovine stephanofilarial dermatitis in alberta

Area of Science:

• Veterinary Parasitology
• Bovine Pathology

Background:

• Bovine parasitic infections pose significant challenges to the livestock industry.
• Stephanofilariasis is a parasitic disease affecting cattle, caused by nematodes of the genus Stephanofilaria.

Purpose of the Study:

• To document the presence of Stephanofilaria stilesi in Alberta beef cattle.
• To describe the clinical and pathological manifestations of the infection.
• To review the parasite's life cycle and lesion development.

Main Methods:

• Nematode recovery from infected beef cattle.
• Gross and microscopic examination of skin lesions.
• Literature review of Stephanofilaria life cycle and pathogenesis.

Main Results:

• Stephanofilaria stilesi was identified in two mature beef cattle.
• Detailed descriptions of the external skin appearance and histological lesions were provided.
• The life cycle and lesion development patterns were reviewed.

Conclusions:

• Confirms the occurrence of Stephanofilaria stilesi in Canadian cattle.
• Highlights the importance of understanding parasitic infections for cattle health.
• Provides a comprehensive overview of stephanofilariasis in beef cattle.
