Mycoplasma and mycoplasma mastitis.
Summary
Mycoplasma mastitis, primarily caused by Mycoplasma bovis, is a sporadic issue in dairy herds globally. Treatment is challenging, with slow recovery and persistent shedding in milk from recovered cows.
Area of Science:
- Veterinary Medicine
- Dairy Science
- Microbiology
Background:
- Mycoplasma-induced mastitis is a recognized concern in dairy cattle, with sporadic occurrences reported internationally.
- Mycoplasma bovis is the most frequent causative agent, though other Mycoplasma species also contribute to bovine mastitis.
- Five distinct Mycoplasma species have been identified in dairy cows experiencing mastitis in California.
Purpose of the Study:
- To document the prevalence and species involved in Mycoplasma mastitis.
- To evaluate the efficacy of current therapeutic approaches for Mycoplasma bovis infections.
Main Methods:
- Isolation and identification of Mycoplasma species from milk samples of mastitic cows.
- Conducting therapy trials for Mycoplasma bovis infected cattle.
Main Results:
- Mycoplasma mastitis has been reported across Europe, Australia, Israel, New Zealand, and the United States.
- Therapeutic interventions for Mycoplasma bovis mastitis yielded discouraging results.
- Infected cows exhibited prolonged recovery periods and continued shedding of Mycoplasma in milk, even after apparent recovery.
Conclusions:
- Mycoplasma mastitis, particularly Mycoplasma bovis, presents a significant challenge in dairy herd management.
- Current treatment strategies are largely ineffective, leading to chronic infections and milk contamination.
- Further research into effective control and treatment measures for Mycoplasma mastitis is warranted.
