“…Recently, Ravaioli et al (2022) have shown that the most commonly bacterial isolates from the uterus of mares are Gram‐positive bacteria. Accordingly, A. hippocoleae was not identified by the authors (Ravaioli et al, 2022). As previously mentioned, the differences in the occurrence of isolated species from the mares' uterus could be influenced by the geographic locations and the handling of the mares (Davis et al, 2013).…”

“…Finally, although A. hippocoleae is not listed as a common pathogen in uterine infection in mares, it should be included in the differential diagnosis of reproductive failures, since the affected animals may not show clinical signs. Some studies have demonstrated that many swab samples from the uterus have a positive culture only after enrichment and under different atmospheres (Ravaioli et al, 2022). These data reinforce the importance of using different culture conditions to increase the diagnostic sensibility, as performed in the present study, by the use of microaerophilic Ies.…”

Summary Endometritis is recognised as one of the major causes of reproductive failure, specifically infertility and abortions, in mares. Infectious agents are the most common cause of endometritis, mainly bacteria. Here, we describe a case of an unexplained reproductive failure caused by an uncommon bacterium, A. hippocoleae, in a 15‐year‐old Thoroughbred mare with an oscillating reproductive history from Southern Brazil. Strain A. hippocoleae_LBV077/21 was isolated from the mare's uterus swab and identified by MALDI‐TOF (Matrix‐Assisted Laser Desorption Ionisation – Time of Flight) and 16 S rDNA sequencing. The antimicrobial susceptibility test showed that the strain was susceptible to ampicillin, ceftiofur, cephalexin, ciprofloxacin, rifampicin, penicillin, sulfamethoxazole/trimethoprim, tetracycline and vancomycin. Partial 16 S rDNA sequence phylogenetic analysis indicated a well‐supported position of A. hippocoleae_LBV077/21 in an exclusive clade of A. hippocoleae, whilst all other Arcanobacterium species were positioned in a separated clade, highlighting the lower syntenic relationship of the species A. hippocoleae to the other Arcanobacterium species. The present study reaffirms the importance of the isolation and identification of infectious agents in mares in cases of reproductive failure because uncommon agents can impede successful treatment and the improvement of reproductive failures.

“…Uterine lavage by using normal saline after mating is often employed in stud farms because of its ability to increase the tone of uterine muscular layer and its effect in clearing microorganisms, spermatozoa, inflammatory cells and debris from the uterine lumen, as these have been found to contribute to early embryonic death in mares [ 121 ]. Use of lactated Ringer’s solution has also been advocated [ 122 ], whilst the use of iodine povidone solution has not become widely applied, as it might cause local inflammation [ 123 ] and reduced expression of endometrial progesterone receptors, hindering fertility [ 124 ].…”

Antibiotic administration is a standard therapeutic practice for the treatment of reproductive disorders of equids. This might lead to undesirable microbial imbalance and could favour the acquisition of antibiotic resistance. Therefore, it is imperative for clinicians to understand patterns of antibiotic resistance when considering and developing treatment regimes. Continued engagement of clinicians with novel alternative approaches to treat reproductive infections would be essential in order to address this rising threat within the One Health perspective. The objectives of the present review were to present the bacterial infections in the reproductive system of equids (horses, donkeys), to upraise the literature related to the issue of antibiotic resistance of bacteria causing these infections and to discuss the topic from a clinical perspective. Initially, the review summarised the various infections of the reproductive system of equids (genital system of females, genital system of males, mammary glands) and the causal bacteria, providing relevant information about horses and donkeys. Subsequently, the clinical therapeutics of these infections were presented, taking into account the significance of antibiotic resistance of bacteria as a limiting factor in treating the infections. Finally, approaches to circumvent antibiotic resistance in clinical settings were summarized. It was concluded that awareness regarding antibiotic resistance in equine reproductive medicine would increase, as we would recognise the multifaceted problem of resistance. Actions and initiatives within the One Health approach, minimizing the potential dissemination of resistant strains to humans and to the environment, with specific applications in medicine of equids should be appropriately instituted internationally.
