A Romanian vet collects chicken from a farm in the village of Ceamurlia de Jos, 350km ( 220 miles ) southeast of Bucharest, Oct 13, 2005. Vets are using a plastic container to asphyxiate the birds with carbon dioxide gas before burning the carcasses. Experts have confirmed that birds in the Danube delta tested positive for an H5-type bird flu virus, but have not narrowed it to the virulent H5N1 strain found in Turkey.  (AP/Robert Ghement)
