Improved molecular identification of Strongyloides myopotami in nutrias using fecal samples.

Strongyloides myopotami is an intestinal nematode parasite of nutrias. Identification of S. myopotami is conducted based on the morphological characteristics of adult worms or cultured larvae.

Isolation and characterization of Escherichia albertii from wild and safeguarded animals in Okayama Prefecture and its prefectural borders, Japan.

Escherichia albertii has recently been recognized as a zoonotic enteropathogen associated with food poisoning. The reservoirs and transmission routes of this bacterium to humans are still unclear. In this study, we performed a survey of E.

Effects of uric acid on nitrosation of N-acetylcysteine by diethylamine NONOate and N-acetyl-N-nitrosotryptophan.

Uric acid of human plasma concentration accelerated nitrosation of N-acetylcysteine by diethylamine NONOate at neutral pH, but diminished that of N-acetyltryptophan. Uric acid also accelerated nitrosation of N-acetylcysteine by N-acetyl-N-nitrosotryptophan, having a nitroso group on the nitrogen atom of the indole ring. N-Acetyl-S-nitrosocysteine was stable even in the presence of uric acid and N-acetyltryptophan at neutral pH, while decomposition of N-acetyl-N-nitrosotryptophan was accelerated by uric acid and N-acetylcysteine.
