Foot-and-mouth disease virus was collected during two years throughout Bangladesh. Viral RNA from 40 samples was subjected to reverse transcription-dependent polymerase chain reactions that amplify parts of the capsid protein encoding genome region, and the products obtained were sequenced. This showed that all virus isolates up to January 1999 belonged to a genotype of serotype O, observed here already in 1987, 1996 and 1997, and elsewhere since 1990. In February 2001, this virus variant was introduced into Great Britain and then transmitted to other European countries. The capsid protein sequences of an isolate of 2001 from the Netherlands is provided. Later isolates from Bangladesh, however, belonged to a genotype of serotype A that had been transmitted to Albania in 1996. No virus of type Asia1 was found, although it circulated in Bangladesh in 1996. Instead, this genotype of Asia1 virus was observed in Iran late in 1999, and transmitted from Turkey to Greece in July 2000. The results indicate continued intercontinental transmission of foot-and-mouth disease viruses that circulate in central Asia
