title: Isolation of A/Equi-2 virus during 1987 equine influenza epidemic in India.
abstract: Processing of nasal materials from clinical cases during the 1987 influenza epidemic in Northern and Central India resulted in the isolation of two haemagglutinating agents; one each from donkeys and horses at Bhiwani in Haryana State and Ludhiana in Punjab State, respectively. These were typed as Influenza A/Equi-2 viruses by haemagglutination inhibition test. The two isolates were designated as A/Equi-2/Bhiwani/1/87 and A/Equi-2/Ludhiana/1/87. The Bhiwani/87 isolate was confirmed to have H3N8 antigenic structure and was indistinguishable from the Miami/63 strain of A/Equi-2 virus. However, the A/Equi-2 Ludhiana/87 isolate was closely related to the Fontainebleau/79 strain of A/equi-2 virus.
