Summary
Mycotic abortion in Danish cattle occurs in 14% of cases, with higher rates in winter. Aspergillus fumigatus is the most common fungal cause of these bovine abortions.
Area of Science:
- Veterinary Mycology
- Animal Reproduction
Background:
- Mycotic infections are a significant cause of abortion in cattle.
- Understanding the epidemiology of mycotic abortion is crucial for herd health management.
Purpose of the Study:
- To investigate the occurrence and characteristics of mycotic abortion in Danish cattle.
- To identify the fungal agents responsible for bovine abortions.
Main Methods:
- A six-year survey of 748 bovine placenta samples.
- Microscopic, histological, and culture-based examination for fungal identification.
Main Results:
- Mycotic abortion was diagnosed in 14% of cases (101/748).
- Higher incidence (21%) observed in winter months (December-February).
- Aspergillus fumigatus was the predominant pathogen (77 cases).
Conclusions:
- Mycotic abortion is a notable cause of pregnancy loss in Danish cattle.
- Seasonal variations and specific fungal agents influence the occurrence of mycotic abortion.
