Necropsy of rare bovine conjoined twins
...that have been shown to induce fetal anomalies in ruminants include bovine viral diarrhea virus (BVD), Cache Valley fever virus, and bluetongue virus. Testing for these viruses is recommended in any diagnostic workup of conjoined twins. A viral cause was not detected in this case. For more information about this case, contact Dr. Erin Edwards or Dr. Gaya Balamayooran, veterinary pathologists at the College Station laboratory. To learn more about b...

The bacterial culture yielded a mixed bacterial growth, likely due to contamination. Based on rtPCR testing, Leptospira nucleic acid was detected in the sample. PCR results for other pathogens were n...
