Veterinary Updates:

  • 2004 - 2005 mortality report:

          Stillbirths     1.1.1

          Neonatal death    1.0.0


            Neoplasia    0.1.0

            Exhibit-related (drowning) 0.1.0

            Amyloidosis/renal disease 0.1.0

            Cardiac causes

              Infarction   1.0.0 (29 yr)

              Congestive failure 3.0.0 (41, 51, 57 yrs)

            Pending final results  0.2.0 

          Total     6.6.1 

  • Veterinary consultations:
    • Considering the mortality profile this year, it is not surprising that consultations on congestive heart failure and cardiac disease were substantial in number.  Prevention of obesity, good exercise programs, and regular physical examinations that include cardiac consultations are important not only in middle aged but also for geriatric animals.

      Options for control of cardiac disease are available but early diagnosis remains essential for best response. 

    • Contraception continues as an important aspect of management of this species.  Pre-pubertal or at puberty oral contraceptive administration and reversible vasectomies are addressed in revisions of the Reproduction chapter of the husbandry manual.
    • Coccidiomycosis has been previously diagnosed in three chimpanzees in the last 10 years but only once as the primary cause of death with the other two cases responding to treatment.  It should be considered as a differential for respiratory disease or wasting conditions in chimpanzees housed in the SW USA or recently moved from those areas.  Serologic testing is available for this fungal organism which can be incorporated into annual/bi-annual routine physicals for baselines and tracking.
  • Veterinary presentations at annual class
    • Cardiac disease and congestive heart failure (K. Backues)
    • Deconstruction of the annual examination (K. Backues)
    • Contraception (K. Backues)
    • Diabetes mellitus (J. Wynne)
  • Revisions to husbandry manual/chapters
    • Contraception – completed and will be incorporated into Welfare Guidelines (K. Backues)
    • Veterinary care – in progress and will be incorporated into Welfare Guidelines (K. Gamble)
  • Consultation with Gombe was ongoing on several aspects of medicine this year.  Fecal parasite survey by technical staff at Lincoln Park Zoo has continued and will result in an identification atlas for "in-field” use.  One of cases of ‘wasting’ reported in older male chimpanzees was identified with a substantial enteric parasitism (Oesophagostomum sp.).  Two other animals were presented following substantial intra-troop antagonism which required injury consultation and subsequently full necropsies provided by Zoological Pathology Program, Urbana, IL.
  • Upcoming projects will include an SSP Veterinary Advisor report proposed for a presentation at the annual meeting of the American Association of Zoo Veterinarians/American Zoo and Aquaria meetings, 2006, Tampa, FL, and development of a cardiac disease formulary based on recent experiences and uses, reviewed by human cardiologists for additional new medications to consider.
