Introduction

The Month of March witnessed an increase in injury cases especially in Elephants with arrow injuries leading followed closely by snares. Many of the arrow wounds targeted bulls, a clear indication of poaching attempts due to their huge tusks. The hotspots were Ithumba, southern Tsavo East and Tsavo West near Mwakitau. Other cases included rescue of an abandoned crocodile at a closed down facility in Bachuma gate, treatment of a sick security dog and autopsy of lion carcass. Cases are expected to reduce owing to the oncoming rains that have already started.

Case #1 Treatment of an injured Elephant: 

Date: 3rd March 2014

Species: Elephant

Sex: Male

Location: Dida Harea Tsavo East

History:

The Elephant bull was reported injured by tourists visiting the southern part of the Park limping.

Immobilisation:

He was tracked down and immobilised using 17 mgs of etorphine propelled in a dan inject dart system. It took 5 minutes for the drug to take effect.

Examination:

A big wound on the left rear leg was examined and on further probing an arrow head was retrieved from the wound. Dead tissues were debrided and the septic wound cleaned using water mixed with hydrogen peroxide at a ratio of 1:1. Tincture of iodine and oxytetracycline spray was applied to the wound and a final cover of green used to cover the injured site. Long acting Amoxycillin was injected parenterally.

Prognosis: Good

This is a latent viral disease of elephants caused by Herpes virus and is known to cause deaths only in Asian Elephants. The disease in African Elephants manifests as self limiting nodular lesions in young elephants trunk and face and are rarely fatal. The viruses are intranulclear and have affinity for endothelial cells.

Sampling:

Several Elephants were sampled and blood, tissues from nodular lesions taken and will be tested at our new molecular lab in Nairobi. A total of 15 Elephants were sampled making a total of 50 elephants sampled in Tsavo ecosystem so far.

Case #14 Treatment of an injured Elephant Bull:

Date: 31st March March

Species: Elephant

The bull with heavy tusks was treated near Dida harea wind mill, southern Tsavo east for an arrow wound on the flank after reports were received by tourists.

Darting was done using 17 mgs of etophine. The Elephant had to be rolled over after falling on the injured side. The arrow head was removed, wound cleaned and antimicrobials applied. He was finally revived and given clean bill of health.

Conclusion:

The region is expected to experience continued heavy rain for the next two months that coincides with reduced case load due to water and forage abundance within the protected ares. Elephants will also have time to regain their healthy boby status.
