Case reports play a valuable role in documenting the direct experience of individuals, especially when recorded in systematic detail and independently verified. In this recent case report by homeopathic equine veterinarian Dr Petra Weiermayer (Vienna) a 4-year old horse with delayed wound healing associated with antimicrobial resistant bacteria was treated successfully with homeopathy.

Wound healing disorder and antimicrobial resistance in a horse

Case reports play a valuable role in documenting the direct experience of individuals, especially when recorded in systematic detail and independently verified. In this recent case report by homeopathic equine veterinarian Dr Petra Weiermayer (Vienna) a 4-year old horse with delayed wound healing associated with antimicrobial resistant bacteria was treated successfully with homeopathy*.

After surgical treatment of a deep lacerated wound to the right foreleg, the horse failed to respond to appropriate antibiotic treatment. A deep wound swab identified infection with antimicrobial resistant bacteria. Subsequent treatment with homeopathic medicine Silicea terra resulted in complete resolution of the clinical signs of delayed wound healing (putrid inflammation, edema and seroma) and full closure of the wound within five weeks; the improvements were maintained for over a year with no relapses.

Importantly, the case was also documented by the attending independent veterinary surgeon, the horse owner and other horse owners at the same stable, providing valuable external validation.

Considering the global threat of antimicrobial resistance, well-documented cases such as this can form the basis of large-scale clinical studies to assess the potential impact of homeopathy on antibiotic stewardship and treatment of resistant infections. 

Overall, the systematic review evidence in veterinary homeopathy remains unclear – there is insufficient data either to rule out an effect beyond placebo or to demonstrate clear efficacy/effectiveness of homeopathy.

Given the positive anecdotal evidence reported by veterinary homeopaths, farmers and animal-owners, plus the positive trends seen from the small number of robust studies which have been conducted to date, further high quality research is needed as a matter of urgency to clarify the roles which homeopathy may be able to play in improving animal welfare and tackling challenges such as anti-microbial resistance.

Petra Weiermayer, DVM EAVH Diploma

Petra explains on her website “With the aim of being able to offer my patient – your horse the best possible homeopathic treatment , I have acquired practical experience in equine medicine, numerous internships at home and abroad and a one-year internship at the equine clinic of the University of Veterinary Medicine Vienna.started my studies intensively with veterinary homeopathy and participated in numerous seminars on various topics in veterinary homeopathy.

Professional competence can only be guaranteed through appropriate training – also in homeopathy. The EAVH (European Academy for Veterinary Homeopathy) offers the possibility of well-founded training with a recognized qualification (diploma or certificate), which I successfully completed in March 2009 after studying for two years . With the exam in August 2019, I have now successfully completed the multi-year theoretical and practical training as a specialist veterinarian for homeopathy, awarded by the Austrian Chamber of Veterinarians.

Since 2009 I have been volunteering for homeopathy. From 2015 to 2018 I was general secretary of the IAVH (International Society for Veterinary Homeopathy), since 2018 I have been President of the ÖGVH (Austrian Society for Veterinary Homeopathy) and since 2019 head of the Research Section of WissHom (Society for Scientific Homeopathy). My areas of expertise are scientific, political and public relations!

She is currently President of the Austrian Association for Veterinary Homeopathy (www.oegvh.at) and Spokeswoman of the Department of Research of the Scientific Society for Homeopathy (www.wisshom.de) and Specialist for Homeopathy.
