The prevalence of some swine reproductive and zoonotic diseases in Colombia is still unknown, making their management difficult. This study assessed the prevalence of porcine circovirus type 3 (PCV3), Leptospira interrogans, pseudorabies virus, and porcine gamma-herpesvirus by polymerase chain reaction in sows in the productive stage, from farms with a history of reproductive failures, at the department of Tolima. The prevalence of PCV3 was 2.6% and 12.6% for L. interrogans, with some samples co-infected with PCV2. Owing to the coinfections with PCV2, it is necessary to establish whether the interactions between these pathogens were related to the presence of reproductive problems.

Splenic myelolipoma is a rare tumor in dogs with an unclear origin. A male 13-yearold Schnauzer dog was presented because of a bump on the left side of the abdomen. Clinical examination and abdominal ultrasound revealed a mass in the spleen. A total splenectomy was carried out, and histopathology revealed a splenic myelolipoma. Before surgery, the patient showed high serum alanine aminotransferase levels, which returned to normal eight months after the resection. Unfortunately, the postoperative follow-up showed increased serum cholesterol and triglyceride levels, suggesting liver compromise. This is the first report of a splenic myelolipoma in Colombia.
