The aim of this study was to evaluate the growth of the B. abortus reference strains and field isolates on media containing different inhibitor agents. Reference strains were seeded on tryptose agar containing: i-erythritol (1.0 mg/mL), fuchsin (20 μg/mL and 80 μg/mL), thionin (2.5 μg/mL and 10 μg/mL), rifampicin (200 μg/mL) and safranin O (200 μg/mL). Field isolates were tested only on media c...

In ruminants, such as cattle, sheep, and goats, common forms of listeriosis are abortion, stillbirth, or postnatal death of the young infected animal (M. L. Gray et al., Am. J. Vet. Res. 17: 510, 1956; J. W. Osebold et al., J. Am. Vet. Med. Assoc. 137:221, 1960). By experimental oral exposure of pregnant sheep and goats, M. L. Gray et al. have shown the reproductive system of these animals, esp...

The title Sm(III)-erythritol complex, [Sm(NO3)3(C2H6O)(C4H10O4)], is isotypic with its Nd, Eu, Y, Gd, Tb and Ho analogues. The Sm(III) cation exhibits a coordination number of ten and is chelated by a tridentate erythritol ligand and three bidentate nitrate anions. It is additionally coordinated by an O atom of an ethanol mol-ecule, completing an irregular coordination sphere. The Sm-O bond len...

Plasmodium falciparum aquaporin (PfAQP) is a multifunctional channel protein in the plasma membrane of the malarial parasite that causes the most severe form of malaria infecting more than a million people a year. This channel protein facilitates transport of water and several solutes across the cell membrane. In order to better elucidate the fundamental interactions between PfAQP and its perme...

This study investigates the influence of polyol compounds (sorbitol and erythritol) on osmotic dehydration process pomegranate seeds. The efficacy was estimated based determination water loss, weight reduction, solid gain, effective diffusivity also through a comparison results obtained between sucrose solutions. Response surface methodology used to optimize process. Quality attributes seeds we...

The function, structure and mechanism of two Escherichia coli enzymes involved in the non-mevalonate route of isoprenoid biosynthesis, 2C-methyl-D-erythritol 4-phosphate cytidylyltransferase and 2C-methyl-D-erythritol 2,4-cyclodiphosphate synthase, are reviewed. Comparisons of each with enzymes from microbial pathogens highlight important conservation of sequence suggestive of similarities in s...

With the finding that xylitol is an intermediate in the glucuronate-xylulose pathway (2, 3)) experiments were undertaken to determine whether this pentitol occurs in human urine. Instead of xylitol, the analyses led to the isolation of n-arabitol from pentosuric urine as well as nL-arabitol from normal urine (4). During the fractionation of urinary polyols on Dowex l-borate columns, eluates wer...

Drosophila suzukii, spotted-wing drosophila (SWD), is a fly pest of small fruits and cherries often managed by chemical insecticides, finding convenient, human-safe alternative challenge. Erythritol, non-caloric sugar, safe for humans toxic to D. suzukii causing an osmotic imbalance. Combining erythritol with sucrose as phagostimulant can enhance mortality. However, sticky when applied on plant...

the values of fourteen carbohydrates assimilation patterns were investigated for typical and atypical strains of microsporum canis. thiry eight strains of typical and twenty two strains of atypical microsporum canis, microsporum canis ncpf 352 and one microsporum distortum were included in this study. statistical analysis of the results indicated that despite limited variations within the patte...
