Authorities at Nandankanan zoo in the coastal state of Orissa, India, have
admitted that administering the wrong drug indirectly killed 11 Royal Bengal
tigers within the space of 48 hours last week. On 23 June, one tiger had
contracted trypanosomiasis, a protozoan disease carried by mosquitoes and flies
that disables the central nervous system. As a precaution, the zoo gave all the
tigers what they thought was a drug targeting trypanosomiasis, but was in fact a
general antibiotic which allowed the infection to spread.
