Ivory coast: Ravens did not die from H5N1

25-11-2009 | |

In October, the ag authorities of Ivory coast reported that 30 wild white-necked ravens were found dead on a secondary school ground in Abidjan. Nine birds tested positive on the highly pathogenic avian influenza virus H5N1. However, tests conducted by the OIE reference lab in Padova do not confirm H5N1 infection.

The results obtained by the OIE Reference Laboratory in Padova were negative for avian influenza by RT-PCR, virus isolation in embryonated eggs, sequencing, intravenous pathogenicity index test and hemagglutination inhibition test.

Further tests were carried out by the same laboratory for Newcastle disease and West Nile fever and they were negative.

Concerning the ravens that died in Abidjan, some people revealed that they had spread a toxic product, mainly Gambaril, which could be the origin of the deaths reported. However, toxicological tests gave negative results.
