Colorimetric determination of neutral sugars by a resorcinol sulfuric acid micromethod
TL;DR: A microscale colorimetric assay for neutral sugars, in which neutral sugars react with resorcinol in the presence of 75% sulfuric acid solution is described, which allows accurate determinations with small samples containing 1 to 100 nmol of neutral sugars and is quite convenient for detection of glycoconjugates in chromatographic column effluents.

TL;DR: Examples of zoonotic helminth infections that have newly appeared in human populations, or have existed but are increasing in incidence or geographic range are described.

Schistosoma mansoni and Biomphalaria: past history and future trends.
TL;DR: Molecular phylogenetic studies suggest that Schistosoma mansoni originated in Asia, and that a pulmonate-transmitted progenitor colonized Africa and gave rise to both terminal-spined and lateral-Spined egg species groups, the latter containing S. mansoni.

TL;DR: A case of cutaneous gnathostomiasis diagnosed in the United States is reported, and a clinical review of the English-language literature on human gnathOSTomiasis is presented.

Mechanisms of molluscan host resistance and of parasite strategies for survival.
TL;DR: A possible molecular basis for the susceptibility/resistance dichotomy in molluscan schistosomiasis is suggested to be deficient forms of enzymes in the respiratory burst pathway, and a selective disadvantage forschistosome resistance is an integral component of this model.
