BACKGROUND Taenia prevalence has remained high among certain ethnic groups and occupational diseases in Nepal. Taenia saginata and Taenia solium species are worldwide in distribution. Infection is found most often in rural areas of developing countries with poor hygiene and living in close contact with pigs and eating undercooked pork meats. This allows the tapeworm infection to be completed an...

Three species of tapeworms infect humans in their adult stage (Taenia solium, Taenia saginata and Taenia asiatica). The 3 are flat, opaque white or yellowish, and exceptional long segmented parasites, measuring 1 to 12 m in their adult stage. In this review, the development of the knowledge regarding the first species, mainly focused on understanding how the larval stage or cysticercus is trans...

Not only Taenia solium and Taenia saginata, but also Taenia asiatica infects humans. The last species is not included in the evaluation of the specificity of the immunodiagnostic techniques for taeniasis/cysticercosis. There is currently no specific immunodiagnostic method for T. asiatica available. Therefore, due to the fact that molecular techniques (the only tool to distinguish the 3 Taenia ...

Cladistic analysis of a numerical data matrix describing 27 characters for species of Taenia resulted in 4 most parsimonious phylogenetic trees (174 steps; consistency index = 0.28; homoplasy index = 0.72; retention index = 0.48). Monophyly for Taenia is diagnosed by the metacestode that is either a cysticercus or a form derived from a bladder-like larva; no other unequivocal synapomorphies are...

We collected fecal samples from 21 individuals infected with Taenia tapeworms in Koh Kong Province, Cambodia, and performed nucleotide sequencing of the cox1 gene and multiplex PCR on the eggs for DNA differential diagnosis of human Taenia tapeworms. Genomic DNA was extracted from the eggs of a minimum number of 10 isolated from fecal samples. Using oligonucleotide primers Ta7126F, Ts7313F, Tso...

A newly described Asian taeniid which is morphologically indistinguishable from adult Taenia saginata has been identified in the aboriginal population of Taiwan. Hybridization patterns of restriction enzyme digested genomic DNA isolated from "Taiwan" Taenia and Taenia saginata revealed distinct variations between these cestodes. We have demonstrated by Southern blot analysis of ribosomal DNA fr...

mazandaran province, northern iran, has been an area with highest prevalence of infectivity with human taeniasis during past decades. in order to assess current situation of taeniasis in the province by a method which can yield a correct estimation of infection rate, this study was performed by administrating anti-taenia drug, during 2003-2004. a total of 417 people were randomly selected from ...

Intestinal obstruction may be duo to various mechanical or functional reasons. Worms, especially Ascaris worms are one of the mechanical reasons of intestinal obstruction. Obstruction due to Taenia saginata is a rare phenomenon. Here we report a case of intestinal obstruction due to Taenia saginata infection in a 30 year-old male patient undergoing laparatomy with the diagnosis of intestinal ob...

SUMMARY hydatic cyst is a serious disease of man. That cause by a worm called taenia echinocococus, the adult worm lives in small bowel of dog and other canine host. The dog is the usual definitive host of this parasite and is important for transmition of this disease. In this study a total of 283 stray dags Teheran country were investigated for the present of intestinal metazoan parasites. T...
