Background    Taenia saginata  is a tapeworm found in cattle worldwide. Analysis of genetic diversity in different geographical populations of  T. saginata  not only helps to understand the origin, transmission and spread of this organism, but also to evaluate the selection pressures acting on  T. saginata  and how it is responding to them. However, there are few reports of the genetic variability of  T. saginata  populations in different regions of the world, including Lao PDR and Thailand. We report the genetic diversity of  T. saginata  populations in Lao PDR and northeastern Thailand together with sequences of  T. saginata  from other countries deposited in GenBank.    Results  Mitochondrial  cox 1 sequence analysis revealed that 15 and 8 haplotypes were identified in 30 and 21  T. saginata  isolates from Lao PDR and northeastern Thailand, respectively. Fifty-three haplotypes were identified from 98 sequences. Phylogenetic tree and haplotype network analyses revealed that global isolates of  T. saginata  were genetically divided into five groups (A, B, C1, C2 and D).  Taenia saginata  isolates from Lao PDR and northeastern Thailand belonged to either Group A or B.  Taenia saginata  from western Thailand clustered in groups C1, C2 and D, and populations from the northeast and western Thailand were found to be genetically distinct.  Taenia saginata  isolates in Lao PDR and Thailand were also found to be genetically diverse but the degree of genetic differentiation was low.    Conclusions    Taenia saginata  populations from Lao PDR and northeastern Thailand are genetically distinct from the population in western Thailand and it is proposed that  T. saginata  has been dispersed by different transmission routes in Southeast Asia.
