ODA Animal Disease Diagnostic Laboratory


Necropsies are primarily of food
production animals (cattle, swine, sheep, goats) and poultry (turkeys,
chickens), with fewer horses, dogs, cats and miscellaneous animals (few exotic
animals, deer and other wildlife, camelids and pet birds).

The necropsy suite includes
overhead monorail with two 2-ton hoists, two stainless steel hydraulic tables,
holding pens and cages, coolers to store animals/infectious wastes, and a fume
hood for histopathology tissue trimming. Personal protective equipment includes
surgical scrubs, coveralls, lab coats, disposable gloves, aprons and surgical
masks and hats, eye goggles and face shields, and Kevlar gloves. Dual headed Olympus and Zeiss microscopes are available for dual
viewing of microscope slides. There are multiple computers in the section with
access to the laboratory database, email and the internet.

          The student will participate in
          the performing of necropsies on animals and birds presented to the ADDL for
          diagnosis. The student will assist the veterinary pathologist/diagnostician on
          duty each day, and they will be present during client interviews to obtain case
          histories prior to performing post-mortem examinations. The student will be
          able to observe microscopic slides of tissues for histopathology of case
          material through a 2-headed microscope with the pathologist. The student will
          also be able to observe activities in other lab sections, such as bacteriology,
          virology and serology. The student can expect to see 20-25 necropsies per week
          and a similar number of accessions received by mail.

          Students in this program will
          have to sign a waiver of liability approved by ODA legal counsel. Students will
          also need to have documentation of a protective titer against rabies and of
          tetanus immunization.

          Student Supervision

          At least 4 hours per day – the
          student will be assigned to assist the pathologist or diagnostician on duty
          each day.
