| first ultrastructural data on the human tapeworm taenia asiatica eggs by scanning and transmission electron microscopy (sem, tem). | humans are definitive hosts of three species of the taenia genus, namely taenia solium, taenia saginata and taenia asiatica. the relative novelty of the latter explains the lack of knowledge concerning certain relevant aspects related to this parasite, such as its definite geographical distribution and whether its eggs can infect humans or not. so far, only the eggs of t. solium are known to be infective for humans, producing cysticercosis. although eggs contain the infective stage, the oncosphe ... | 2016 | 27277232 |
| simple identification of human taenia species by multiplex loop-mediated isothermal amplification in combination with dot enzyme-linked immunosorbent assay. | for differential detection of taenia solium, taenia saginata, and taenia asiatica, loop-mediated isothermal amplification (lamp) assay targeting the cytochrome c oxidase subunit 1 gene has been recently developed and shown to be sensitive, specific, and effective. however, to achieve differential identification, one specimen requires three reaction mixtures containing a primer set of each taenia species separately, which is complex and time consuming and increases the risk of cross-contamination ... | 2016 | 27044566 |

| lights and shadows of the taenia asiatica life cycle and pathogenicity. | humans are definitive hosts of two well-known species of the taenia genus, taenia solium (the pig tapeworm) and taenia saginata (the cattle tapeworm). in the 1990s, a third species, taenia asiatica, was discovered, sharing features with the other two since the adult morphology is similar to that of t. saginata, but its life cycle is like that of t. solium. human taeniasis usually is asymptomatic or displays mild symptoms, and only t. solium can cause other sometimes serious disorders when humans ... | 2013 | 24470994 |
