Letters ANTIMICROBIALS
Routine antibiotic dry cow therapy WE would like to thank Trevor Jones (VR, January 30, 2016, vol 178, p 123) for his corrections regarding the history of the use of infusion of antibiotic preparations into cows at dry-off and the subsequent development of long-acting preparations, following publication of our Editorial ‘Antibiotic dry cow therapy: where next?’ (VR, January 23, 2016, vol 178, pp 93-94). It is important that the details are recorded accurately. We also recognise that the ‘Five Point Plan’ was the original name and that ‘Mastitis Control’ was inadvertently added for clarity. We would like to stress that there are quite a few situations when (environmental) risks increase the likelihood of a new intramammary infection occurring during the dry period. Detailed advice can only be given with an in-depth knowledge of the individual farm situation; discussions in this area were outside the scope of the article but deserve specific consideration. Summer mastitis is a relatively uncommon example of a dry period infection arising from increased environmental risk, and local history/knowledge suggests that, when the risks are high, control of summer mastitis without antibiotic dry cow therapy may be difficult. We agree with Mr Jones, however, that the extent of protection provided by internal sealants alone for summer mastitis is uncertain.

Correction Use of antibiotics in animals and people, David Burch (VR, February 6, 2016, vol 178, p 146). The penultimate sentence of the first paragraph of this letter should have read ‘My only surprise came from the degree of transmission, that is, 2/747 (0.27 per cent), and the majority (99.73 per cent) seem to be human derived’ and not as stated.
