Risk factors for MRSA infection in companion animals: results from a case-control study within Germany. Increasing numbers of companion animals suffering from infections with methicillin-resistant Staphylococcus aureus (MRSA) have been reported in the recent past. These infections are of particular concern because of the limited treatment options for MRSA and their transferability to humans. Since MRSA lineages isolated from infected companion animals often mirror typical human epidemic strains circulating in the same region, successful strategies to combat MRSA need strong and coordinated efforts from both, the human and the veterinary field according to the "One Health" concept. Hence, to iden...
Successful practice of electroacupuncture analgesia in equine surgery. Electroacupuncture analgesia was used for surgery in horses and donkeys. A KWD-808 electrical stimulator was used to incrementally induce a dense, dispersed wave output at frequencies from 20 to 55 Hz, which was maintained at a frequency of 55 Hz, and to change the amplitude of the wave to the best grading number for the suggested operation in each animal. Induction of analgesia lasted for 20-30 minutes, and the effect of analgesia was maintained for 20-45 minutes depending on the type of surgery performed. The exhibited clinical signs, physical examination data, and the responses of all ani...

Crystalloid and colloid therapy. Fluid therapy is a cornerstone of emergency medicine, but equine practitioners should be aware of recent developments that have modified previous recommendations. First, new emphasis on the avoidance of hyperchloremia suggests that crystalloids with a lower chloride concentration may be more appropriate for use. Second, modifications to the understanding of the Starling equation suggest that the benefits of colloids may be more limited than previously thought. In addition, the negative effects of fluid overload on morbidity and mortality are becoming increasingly recognized. Although more spec...
Uterine adenocarcinoma in a Przewalski’s wild horse (Equus ferus przewalskii). A 25-yr-old, nulliparous, female Przewalski's wild horse (Equus ferus przewalskii) with a history of pituitary pars intermedia dysfunction and recent onset of serosanguinous vaginal discharge was euthanized after a period of lethargy and inappetance. Postmortem examination confirmed an infiltrative uterine adenocarcinoma, which is an uncommon neoplasia in equids. Reproductive disease is significant in this species as they are considered endangered by IUCN. Reproductive soundness and success are paramount to conservation efforts.
Strategies for improving the welfare of working equids in the Americas: a Chilean example. In the past, the use of animals for transport and traction has been of economic importance all over the world, and this is still the case in certain areas of the world today, especially in rural and peri-urban areas of developing and transition countries. In Chile, for example, thousands of families rely on draught animal power as a fundamental source of income. This provides an opportunity to generate scientific information to increase understanding of the relationship between human well-being and that of domestic animals. Minimising the risks associated with poor draught animal welfare shoul...
