Forest personnel in Gujarat's Bhavnagar district have intensified surveillance, deworming and de-ticking measures for Asiatic lions as a precaution following the death of eight cubs due to suspected Babesia infection in the Gir forest region, a senior official said on Monday.

Deputy Conservator of Forests (Bhavnagar) Yogesh Desai said no symptoms linked to the suspected infection have been found among lions in the district so far.
