isolated from the animal. If this is not possible, therapy should be based on local
(regional, farm level) epidemiological information about susceptibility of the
target bacteria.
Use of the veterinary medicinal product deviating from the instructions may
increase the risk of development and selection of resistant bacteria and
decrease the effectiveness of treatment with other macrolides due to the
potential for cross-resistance.

avoided. Personal protective equipment consisting of impervious gloves and a
