Biopsy Service

The Biopsy Service in the Department of Veterinary Pathobiology (VTPB) handles tissue samples from patients of the Veterinary Medical Teaching Hospital (VMTH). The timely reports provided by pathologists allow clinicians to make accurate diagnoses and properly tailor treatment. The service examines 900–1000 biopsies per year.

Clinical Microbiology/Immunology Service

The Clinical Microbiology/Immunology group provides laboratory diagnostic tests and consultation for clinicians, develops diagnostic tests, supports faculty research, and teaches students how to use appropriate laboratory tests and how to interpret test results how to best care for their veterinary patients.

Contact Dr. Sara Lawhon or Dr. Artem Rogovskyy for information related to clinical microbiology at or

Clinical Parasitology Service

From microscopic to macroscopic, parasites come in all sizes and shapes and cause a myriad of animal (and human) health issues. The Clinical Parasitology Laboratory supports the VMTH, as well as private veterinary practitioners in association with the Texas A&M Veterinary Medical Diagnostic Laboratory (TVMDL), to offer a wide variety of diagnostic services.

Contact Dr. Guilherme Verocai for information related to clinical parasitology at 979 852-4999 or

Clinical Pathology Service

Veterinary Clinical Pathology, also referred to as Laboratory Medicine, studies disease in animals through the examination of blood, tissues, and fluids. The discipline covers a wide range of laboratory assays and methods, oversees the quality and accuracy of laboratory tests, and assists clinicians with diagnosis, patient care, and prevention of disease. The laboratory supports clinicians and researchers in the college and also trains resident veterinarians in the specialty of clinical pathology through a nationally recognized residency program.

For information related to clinical pathology call 979-845-9180.

CVM Histology Laboratory

The CVM Histology Laboratory provides services for histological sample preparations from tissue embedding to sectioning and staining.

Visit the CVM Histology Laboratory website for more information, or contact Chaitali Mukherjee, Lab Supervisor, at 979-862-1994 or

DNA Technologies Core Laboratory

The DNA Technologies Core Laboratory provides automated nucleotide sequencing, genotyping, and bacterial and fungal DNA sequence-based identification technologies. It also offers individual identification, parentage testing, and genetic trait testing for livestock producers, wildlife managers, and clinical microbiology labs worldwide. The lab houses shared capital equipment used by researchers and students throughout the college.

Dermatopathology Service

The Dermatopathology Service provides quality interpretation of skin biopsy specimens from veterinary dermatologists, general veterinary clinicians, and university veterinary teaching hospitals by a dermatopathologist (a board certified veterinary pathologist who has specialized in dermatopathology). We look forward to working with you.

Visit the Dermatopathology website for more information.

Panfungal PCR & Sequencing for Formalin-Fixed Paraffin Embedded Tissues Service

The Dermatopathology Service provides a panfungal PCR and sequencing for formalin fixed paraffin embedded tissues. The assay can be run on different animal species and tissue samples.

Necropsy Service

Members of the department perform necropsies (postmortem examinations) on patients of the VMTH. Tissue samples collected during necropsy are examined microscopically by pathologists in order to answer important clinical questions, and information gleaned from necropsies is often presented at scientific meetings and published in journals to help advance our understanding of animal disease. All fourth-year veterinary students spend two weeks in the service to learn proper necropsy and sample collection techniques.

Contact Shelley Sides for information related to necropsy at 979-845-4654 or

Veterinary Biorepository

The mission of the Biorepository is to collect and store biological samples and associated clinical information from healthy and diseased animals. These samples are made available to the scientific community to investigate the genetic and molecular basis of traits and diseases in animals.
