Do motor protein mutations cause a new form of hereditary spastic paraplegia?
KIF1C is the third kinesin gene involved in the pathogenesis of HSPs and is characterized by a mild dominant and a more severe recessive disease phenotype. The identification of KIF1C as an HSP disease gene further supports the key role of intracellular trafficking processes in the pathogenesis of hereditary axonopathies.
Ziehl-Neelsen staining can occasionally distinguish fully mature T. solium from T. saginata eggs, but this distinction is neither very sensitive nor completely specific. Differential staining suggests differences in embryophore components between species which become evident with egg maturation. In this small series, egg morphology (shape, maximal diameter) provided appropriate differentiation between T. solium and T. saginata eggs.
