Aminoglycosides (AGs) are important antibacterial agents for the treatment of various infections in humans and animals. Following extensive use of AGs in humans, food-producing animals and companion animals, acquired resistance among human and animal pathogens and commensal bacteria has emerged. Acquired resistance occurs through several mechanisms, but enzymatic inactivation of AGs is the most common one.

Monitoring has confirmed the success of these policies with progressive declines of heavy metals in for example air, sewage sludge and environmental samples. For zinc, such improvements may nevertheless be counter-acted by its widely usage as a feed additive and veterinary medicinal product to piglets in the post-weaning period resulting in reduced occurrence of diarrhea and improvement of daily weight gain.

The need for antimicrobial mass medications is based on beliefs that group/s of animals will contract a bacterial disease (i.e.

Loss of efficacy of antimicrobial substances can seriously compromise animal health and welfare. A need for the development of new antimicrobials for the therapy of multiresistant infections, particularly those caused by Gram-negative bacteria, has been acknowledged in human medicine and a future corresponding need in veterinary medicine is expected.

In pigs, tiamulin and valnemulin are used to treat swine dysentery, spirochaete-associated diarrhoea, porcine proliferative enteropathy, enzootic pneumonia and other infections where Mycoplasma is involved. There are concerns about the reported increases in the MICs of tiamulin and valnemulin for porcine Brachyspira hyodysenteriae isolates from different European countries, as only a limited number of antimicrobials are available for the treatment of swine dysentery where resistance to these antimicrobials is already common and widespread.

Products for in-feed medication with these compounds in combination with other antimicrobials are commonly used in Europe. Most recently approved injectable macrolides have very long elimination half-lives in both pigs and cattle, which allows once-only dosing regimens.

After intravenous administration, elimination of ampicillin was fast and not detectable in plasma after 12h in three out of six horses.
