Teat apex coliform populations and coliform mastitis--a herd study
The Cornell Veterinarian
|July 1, 1975
Summary
Infected quarters are the primary source of coliform bacteria on the teat apex, posing a risk to other quarters and cows. Environmental coliform bacteria on the teat apex appear to be temporary.
Area of Science:
- Veterinary Medicine
- Microbiology
- Animal Science
Background:
- Coliform mastitis is a significant issue in dairy herds.
- Understanding coliform bacteria transmission is crucial for herd health.
Purpose of the Study:
- To investigate the source of coliform bacteria contamination on dairy cow teat apices.
- To assess the risk posed by teat apex contamination to uninfected quarters and other animals.
Main Methods:
- Collection of pre- and post-milking teat samples.
- Teat apex culturing for coliform bacteria identification.
Main Results:
- Infected quarters were identified as the main source of coliform contamination on the teat apex.
- Coliform bacteria from environmental sources showed transient populations on the teat apex.
Conclusions:
- Contaminated quarters are a significant reservoir for coliform bacteria, increasing transmission risk.
- Environmental coliforms on teat apices are less likely to persist, suggesting a lower long-term risk compared to infected quarters.
