8. Provision of scientific and technical training to personnel from other OIE Members

OIE Twinning Project on Brucellosis between National Veterinary Laboratory of Eritrea and Istituto «G. Caporale» Teramo.

The initial Workshop of OIE Twinning between the National Veterinary Laboratory of Asmara, Eritrea and the Istituto “G.Caporale” in Teramo, Italy, was held between 30 March and 10 April 2009. The Eritrean participant was Dr. Ghebrehiwet Teame OIE Delegate of the country.

The Istituto “G.Caporale” personnel contributing to the Workshop were: Prof. V. Caporale (Director of Istituto) Drs R. Lelli, M. Tittarelli, E. Di Giannatale, A. Di Provvido, B. Bonfini, A. Petrini and M. Di Ventura.

According to the needs of the Eritrean partner, the project has been re-formulated especially in the part regarding the venue where to carry out the training periods.

In particular, for what concerns the staff training in the microbiology, serology and reagents production laboratories, it was agreed to send the staff from Teramo to Asmara laboratory and not the contrary, as previously described in the first project version.

Following the Eritrean needs, officers from Istituto “G.Caporale” have carried out missions to the National Veterinary Laboratory (NVL) in Asmara.

Following there are reports of activities in brief carried on in Asmara and in Teramo.
