Neurologic Disease due to Bovine Herpesvirus-5 (BHV-5) Infection in a 3-week-old Charolais mix calf
...on, additional testing was performed in consultation with the submitter. A bovine herpesvirus rtPCR test that detects subtypes 1 and 5 was positive (Ct value 28.5) in the brain tissue of this animal. A gel-based PCR assay that differentiates the subtypes confirmed infection with bovine herpesvirus 5 (BHV-5). BHV-5 is a viral pathogen that was originally classified as subtype BHV-1.3, to differentiate it from the BHV-1.1 and BHV-1.2 subtypes, which...

Bovine B4 Export Panel (rtPCR)
Detection of 4 pathogens known to infect bovine; includes bovine viral diarrhea virus (BVDV), bovine leukemia virus (BLV), infectious bovine rhinotracheitis/bovine herpesvirus-1 (IBR/ BHV-1), and bluetongue virus (BTV), all by real time PCR.
Testing for this combination of pathogens is often useful in fulfilling certain export requirements.
-
Respiratory Disease Panel – Bovine Serology (VN)
Detection of antibodies to common pathogens that cause bovine respiratory disease. Targets include bovine herpesvirus type 1, bovine viral diarrhea types 1a/1b/2, parainfluenza 3 virus, and bovine respiratory syncytial virus.

Necropsy of rare bovine conjoined twins
...iruses 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...

Upon examination, the entire fetus and placenta exhibited severe mummification. Tissues of this fetus were submitted to the molecular section for bovine herpesvirus (BHV)-1, BVDV, Leptospira spp. and Neospora caninum rtP...

Bovine CBC reveals concurrent BLV and Anaplasmosis
...a marginale. Confirmatory testing included BLV PCR and Anaplasmosis ELISA. Bovine leukemia virus (BLV) is a retrovirus spread by contact with bodily fluids through biting flies, breeding, colostrum/milk, and certain management practices. Infections can results in asymptomatic carriers or severe clinical disease. Approximately 40% of infected cattle will develop persistent lymphocytosis, as seen in this case. Although numbers vary between studies,...

Factors involved in a Bovine Respiratory Disease Complex (BRDC) diagnosis
...s A&M Veterinary Medical Diagnostic Laboratory (TVMDL) frequently works on Bovine Respiratory Disease (BRD) cases. Multiple factors lead to a BRD diagnosis, leading many to refer to the syndrome as Bovine Respiratory Disease Complex (BRDC). Affected cattle commonly display signs of fever, lethargy, nasal discharge, and coughing. Some of the factors involved in BRDC are stressors such as weaning, shipping, and weather. From an infectious disease or...
