Methods and Results:

A checkerboard microdilution method was used to study the in vitro interaction of FLC and HNK in 24 azole-R clinical isolates of C. albicans. In vivo antifungal activity was performed to further analyse the interaction between FLC and HNK. In the in vitro study, synergism was observed in all 24 FLC-resistant strains tested as determined by fractional inhibitory concentration index (FICI), and in 22 strains by delta E models. No antagonistic activity was observed in any of the strains tested. These positive

interactions were also confirmed by using the time-killing test for the selected strain C. albicans YL371, which shows strong susceptible to the combination of HNK and FLC. In the in vivo study, the mice with candidiasis were treated successfully by a combination therapy of HNK with FLC, the results showed a decrease of the colony forming unit in infected and treated animals compared to the controls, selleck inhibitor at the conditions

of the treatment used in this study.

Conclusions:

Synergistic activity of HNK and FLC against clinical isolates of FLC-resistant C. albicans was observed in vitro and in vivo.

Significance and Impact of the Study:

This report might provide a potential buy BIX 1294 therapeutic method to overcome the problem of drug-resistance in C. albicans.”
“The present report describes production of 1,3-propanediol by Klebsiella pneumoniae ATCC 15380 from crude glycerol from jatropha biodiesel process.

Optimization resulted in a yield of up to 56 g/L of 1,3-propanediol. A conversion rate of 0.85 mol 1,3-propanediol/mol of glycerol has been obtained. Downstream processing to isolate 1,3-propanediol from the fermentation broth resulted in 99.7% pure product with a recovery of 34%. The pure 1,3-propanediol was polymerized with terephthalic acid successfully to yield polytrimethylene terephthalate.”
“Aims:

To provide comparative genome sequence data for two related model strains of Staphylococcus aureus (SH1000 and 8325-4) that are used extensively in laboratory research.

Methods and AZD1390 research buy Results:

Comparative genome sequencing was used to identify genetic differences between Staph. aureus SH1000 and the fully genome-sequenced ancestral strain, Staph. aureus NCTC 8325. PCR amplification and DNA sequencing were employed to determine which of the genetic polymorphisms identified were also present in Staph. aureus 8325-4, a direct derivative of 8325 and the parent strain of SH1000. Aside from known genetic differences between these strains, Staph. aureus SH1000 harboured 15 single-nucleotide polymorphisms compared with 8325 (of which 12 were also found in 8325-4), and a 63-bp deletion upstream of the spa gene not present in either 8325 or 8325-4.

Conclusions:

Staphylococcus aureus SH1000 and 8325-4 contain a number of genetic polymorphisms relative to the progenitor strain of the lineage (8325) and to each other.
