Prevalence and subtype analysis of Blastocystis in healthy Indian individuals.

There is a growing interest in subtype (ST) analysis of the intestinal parasite Blastocystis due to its extensive genetic diversity that might reflect differences in pathogenicity. Although essential for reference, few studies are available on Blastocystis in healthy individuals. Moreover, molecular epidemiology data on Blastocystis in India still remain to emerge.

Reclassification of Bacillus beijingensis Qiu et al. 2009 and Bacillus ginsengi Qiu et al. 2009 as Bhargavaea beijingensis comb. nov. and Bhargavaea ginsengi comb. nov. and emended description of the genus Bhargavaea.

We have carried out a polyphasic taxonomic characterization of Bacillus beijingensis DSM 19037(T) and Bacillus ginsengi DSM 19038(T), which are closely related phylogenetically to Bhargavaea cecembensis LMG 24411(T). All three strains are Gram-stain-positive, non-motile, moderately halotolerant and non-spore-forming. 16S rRNA gene sequence analyses showed that the strains constituted a coherent cluster, with sequence similarities between 99.

Shewanella indica sp. nov., isolated from sediment of the Arabian Sea.

A Gram-negative, facultatively anaerobic, rod-shaped, catalase- and oxidase-positive bacterium, motile by means of a single polar flagellum and designated strain KJW27(T), was isolated from the marine sediment of Karwar jetty, west coast of India. The strain was β-haemolytic and grew with 0-10 % (w/v) NaCl, at 10-45 °C and at pH 6.5-10, with optimum growth with 2 % (w/v) NaCl, at 37 °C and at pH 7.

Ignatzschineria indica sp. nov. and Ignatzschineria ureiclastica sp. nov., isolated from adult flesh flies (Diptera: Sarcophagidae).

Two Gram-negative-staining, aerobic, non-motile, rod-shaped bacteria, designated strains FFA1(T) and FFA3(T), and belonging to the class Gammaproteobacteria were isolated from the gastrointestinal tract of adult flesh flies (Diptera: Sarcophagidae). Phylogenetic analysis of 16S rRNA gene sequence data placed these two strains within the genus Ignatzschineria with similarities of 98.6 % (FFA1(T)) and 99.
