UK vet stresses prudent use of antibiotics at British Mastitis Conference

Vale Veterinary Group veterinarian and director Andrew Biggs says mastitis treatment needs to be targeted.

In a recent presentation at the British Mastitis Conference, Vale Veterinary Group veterinarian and director Andrew Biggs presented the results of bacteriological tests conducted on 15,194 milk samples between 2014 and 2016. The samples were from cases of clinical mastitis and cows with high somatic cell counts. The analysis looked at the most commonly isolated pathogens found in the milk and how sensitive they were to antibiotics. His results revealed that E. coli showed resistance to routine antibiotics: Ampicillin – 58% sensitive; 10% intermediate; and 31% resistant. For Amoxicillin/Clavulanic acid, 75% were sensitive, 11% intermediate and 14% resistant. Biggs used this study to segue into a more important topic: the prudent use of antibiotics. Mastitis treatment needs to be targeted, he said, and the necessity of antibiotics must be assessed before they are used.
