MONTHLY REPORT - VETERINARY CLINICAL INTERVENTIONS FOR THE SOUTHERN CONSERVATION AREA (MVU) – JUNE  2015

Report by Dr. Michael Njoroge

Monitoring and surveillance in Amboseli National Park and the surrounding ecosystem;

This month the Southern Conservation Area showed a marked decrease in the number of cases reported. This could be attributed to the increased surveillance within the area. The veterinary team carried out an aerial recce twice within the park and surrounding ecosystem at 2 week intervals. The DSWT provided an aircraft for this activity which took one and a half hours each time. The purpose of this exercise was to;

  • See the distribution of wildlife within the park
  • Check for injured/sick animals within the park
  • Check for any unnoticed carcasses within the park and its surrounding ecosystem
  • Check for any unusual activities or happenings within the park and the surrounding ecosystem

No unusual sighting was seen and the animals were seen to be evenly distributed within the park and surrounding ecosystem. The recce was conducted within Kimana, Lengisim, Porini and Marba areas as well as within the park.

  

CASE#1 TREATMENT OF A LAME ZEBRA

Date:  18th June 2015

Species: Zebra             

Sex: Male

Age: Adult

Location: Meshenani, Amboseli Ecosystem

History

A male injured zebra was spotted lame by the veterinary team while on routine patrol. The team made a decision to immobilize, examine and treat the zebra.

Immobilization, examination and treatment

The zebra was immobilized using 7 mgs Etorphine Hydrochloride and 60 mg Azerperone in a 3cc dart from a vehicle using the Dan-inject system. Full immobilization took place after 7 minutes and the zebra fell on lateral recumbence. The zebra was blind folded and Opticlox applied to the eyes to avoid damage.

The zebra was observed to be lame resulting from an injury to the left hock joint. The limb was swollen at the hock joint but no external injury was visible. The zebra was injected with 50 ml Betamox and 50 ml Flunixine meglumine at different sites intramuscularly. The entire operation lasted about 15 minutes.

Reversal

Reversal of the anaesthetic was done using 21 mg Diprenorphine and it took about 4 minutes for complete reversal.

The medication is adminstered  The prognosis is good for a full recovery

Prognosis

The prognosis is good

CASE#2 TREATMENT OF AN ELEPHANT WITH A SPEAR WOUND

Date: 23rd June 2015

Species: Elephant

Sex: Male

Age: Adult, 40-50 yrs

Location: Kiboko, (Chyulu) Amboseli Ecosystem

History

The KWS rangers at the Kiboko area while on their routine daily patrols spotted an injured elephant and made a report to the veterinary team. On arrival, the team found the elephant in a thick, bushy area. The terrain was rocky and therefore darting from foot was the only option.

The dart gun is prepared  The team in search of an injured elephant

Immobilization, examination and treatment

The elephant was immobilized using 18 mgs Etorphine Hydrochloride in a 3cc dart using the Dan-inject system. Full immobilization took place after 8 minutes and he fell on right lateral recumbency. The trunk was maintained patent using a piece of stick placed across the nostril entrances. The ears were used as blindfold.

The elephant has an injury to the leg  The wound is cleaned with lots of water

On physical examination the elephant had a penetrating wound on the right limb most likely caused by a spear. The wound was septic and full of pus. The dead tissue was debrided and removed before the wound was thoroughly cleaned using water and Hydrogen Peroxide and then lavaged using tincture of Iodine.

All the pus is drained from the wound and dead tissue removed  Hydrogen peroxide is then used to clean the wound

Topical antibiotic cream and green clay was then applied into the wound to facilitate healing and avoid infection. The elephant was then injected with 200ml Amoxcycillin, 100ml Flunixine meglumine at different sites intramuscularly. The entire operation lasted about 30 minutes.

The injury has been throughly cleaned  Antiseptic spray is applied to the area

Reversal

The anaesthetic was reversed using 54mg Diprenorphine Hydrochloride into the ear vein. It took about 7 minutes to be fully awake and walk away from the site.

Prognosis

Prognosis is good.

CASE#3 POSTMORTEM OF A HIPPOPOTAMUS

Date of death: 29th June 2015

Date of postmortem: 29th June 2015

Species: Hippopotamus

Sex: Female

Age: Adult

Location: Amboseli National Park

History

A mysterious death of a hippopotamus was reported within the park by the KWS rangers during their normal routine patrol.

General and Physical examination of the carcass

On general examination, the animal was in a fair body condition and was on the left lateral side. No physical injury was observed. There was blood oozing from the anus, genitalia and slightly from the mouth. A decision was made not to open the carcass as some signs suggested a differential diagnosis of anthrax.

This hippo died mysteriously  The team are called to investigate the death of a hippo

Blood smears were collected, examined and found to be free from bacillus rods and any bacterial infection.

Conclusion

Further examination could not be carried out as the carcass had been disposed of. The cause of death could have been a viral infection.
