Development and evaluation of loop-mediated isothermal amplification for detection of Yersinia pestis in plague biological samples.

Background: Several tests are available for plague confirmation but bacteriological culture with Yersinia pestis strain isolation remains the gold standard according to the World Health Organization. However, this is a time consuming procedure; requiring specific devices and well-qualified staff. In addition, strain isolation is challenging if antibiotics have been administered prior to sampling.

A comparative study on the potential of epiphytic yeasts isolated from tropical fruits to produce flavoring compounds.

In recent years, there has been an increasing interest in identifying and characterizing the yeast flora associated with diverse types of habitat because of the many potential desirable technological properties of these microorganisms, especially in food applications. In this study, a total of 101 yeast strains were isolated from the skins of tropical fruits collected in several locations in the South West Indian Ocean. Sequence analysis of the D1/D2 domains of the large subunit (LSU) ribosomal RNA gene identified 26 different species.
