Resolution of two cases of ovarian abscesses in mares subjected to ovum pick up.

Abstract: Currently, for in vitro embryo production in live mares, immature oocytes are retrieved by transvaginal follicular aspiration or ovum pick up (OPU). Occasionally, ovarian abscesses have been described after OPU, but no current consensus exists on how to treat this condition. Objective: To describe diagnosis and successful treatment of ovarian abscesses in two mares subjected to OPU. Methods: Case report. Methods: Case records were reviewed and summarised. Results: In the first case, a pony mare showed tachypnoea, tachycardia, high temperature, leukocytosis, left hindlimb lameness and slight increase in concentration of serum amyloid A. Ultrasonography revealed an increase in the size of the left ovary and two well defined structures suggestive of ovarian abscess. A left ovariectomy by standing laparoscopy was the treatment of choice: the diagnosis was confirmed, and bacterial culture produced heavy growth of Streptococcus equi Zooepidemicus. In the second mare, an abnormal structure was observed in the left ovary in a routine transrectal ultrasonographic exam in the absence of any clinical signs or abnormal blood parameters. A medical approach was chosen and a sample of the purulent material was aspirated with a transvaginal ultrasound-guided approach. The sample yielded a heavy growth of Streptococcus equi Zooepidemicus after culture. Treatment was initiated with rifampicin and trimethoprim-sulfadiazine based on the antibiogram results and the abscess completely resolved after 40 days. Conclusions: Limited to two cases. Conclusions: Ovarian abscesses in mares can be successfully treated both surgically and medically.

This research article describes two cases of successful treatment of ovarian abscesses in mares that underwent Ovum Pickup (OPU), a process of retrieving immature oocytes for in vitro embryo production, emphasizing that such abscesses can be treated both surgically and medically.

Summary of the Research Method

  • The study uses a case report method, providing a comprehensive review and analysis of two cases where mares developed ovarian abscesses post OPU.

Details of the Cases

  • In the first case, the mare exhibited symptoms such as tachypnoea (rapid breathing), tachycardia (rapid heart rate), high temperature, leukocytosis (increase in the number of white blood cells), left hindlimb lameness, and a slight increase in the concentration of serum amyloid A, a marker of inflammation. An ultrasonographic examination showed an enlarged left ovary with two distinct structures suggestive of an ovarian abscess.
  • The chosen treatment for the first mare was a standing laparoscopy ovariectomy, a surgical removal of the left ovary. The diagnosis was then confirmed, and a bacterial culture showed a significant presence of Streptococcus equi Zooepidemicus, a common bacterial pathogen in horses.
  • The second mare lacked any clinical signs of an abscess or abnormal blood parameters, but a routine transrectal ultrasonographic examination revealed an abnormal structure in the left ovary.
  • This case suggested a medical approach where a sample of the purulent material from the abscess was aspirated using a transvaginal ultrasound-guided method. Like the first case, the sample culture revealed a significant presence of Streptococcus equi Zooepidemicus.
  • Based on antibiogram results, the treatment regimen for the second mare included rifampicin and trimethoprim-sulfadiazine. After 40 days of this treatment, the abscess completely resolved.

Key Findings and Conclusion

  • The study emphasizes the successful treatment of ovarian abscesses in mares, stating that it is possible to go both the surgical and medical routes depending on the severity and symptoms presented by the mare.
  • However, the reliability of the study’s conclusion is limited due to the availability of data from just two distinct cases. Further investigation is required to solidify the findings.
