We report a substantial range extension of Ichthyophis multicolor Wilkinson, Presswell, Sherratt, Papadopoulou & Gower, 2014, with new material from Mizoram State, Northeast India. The species was previously known only from its type locality more than 800 km away in Ayeyarwady Region, Myanmar. The species was identified by both its morphology and 16s rRNA gene sequence data. One of the studied individuals represents the largest known specimen for the species (total length = 501 mm; mid-body width = 18.8 mm). Brief comparisons of I. multicolor with the sympatric as well as parapatric congeners in the region, and first barcode data for I. moustakius Kamei, Wilkinson, Gower & Biju, 2009 are also presented.

Isolates of Leptospira from two human cases of leptospirosis in Denmark and France were studied using DNA–DNA relatedness, G+C content, 16S rRNA gene sequence data and pulsed-field gel electrophoresis. These isolates differed from previously described species of Leptospira and are defined as Leptospira broomii sp. nov. The type strain is 5399T (=ATCC BAA-1107T=KIT 5399T).

The relationship of Photorhabdus isolates that were cultured from human clinical specimens in Australia to Photorhabdus asymbiotica isolates from human clinical specimens in the USA and to species of the genus Photorhabdus that are associated symbiotically with entomopathogenic nematodes was evaluated. A polyphasic approach that involved DNA–DNA hybridization, phylogenetic analyses of 16S rRNA and gyrB gene sequences and phenotypic characterization was adopted. These investigations showed that gyrB gene sequence data correlated well with DNA–DNA hybridization and phenotypic data, but that 16S rRNA gene sequence data were not suitable for defining species within the genus Photorhabdus. Australian clinical isolates proved to be related most closely to clinical isolates from the USA, but the two groups were distinct. A novel subspecies, Photorhabdus asymbiotica subsp. australis subsp. nov. (type strain, 9802892T=CIP 108025T=ACM 5210T), is proposed, with the concomitant creation of Photorhabdus asymbiotica subsp. asymbiotica subsp. nov. Analysis of gyrB sequences, coupled with previously published data on DNA–DNA hybridization and PCR-RFLP analysis of the 16S rRNA gene, indicated that there are more than the three subspecies of Photorhabdus luminescens that have been described and confirmed the validity of the previously proposed subdivision of Photorhabdus temperata. Although a non-luminescent, symbiotic isolate clustered consistently with P. asymbiotica in gyrB phylogenetic analyses, DNA–DNA hybridization indicated that this isolate does not belong to the species P. asymbiotica and that there is a clear distinction between symbiotic and clinical species of Photorhabdus.

Gene Sequence Data

The heterocystous cyanobacteria are currently placed in subsections IV and V, which are distinguished by cellular division in one plane (false branching) and in more than one plane (true branching), respectively. Published phylogenies of 16S rRNA gene sequence data support the monophyly of the heterocystous cyanobacteria, with members of subsection V embedded within subsection IV. It has been postulated that members of subsection V arose from within subsection IV. Therefore, phylogenetic analysis of nucleotide sequences of the nitrogen-fixation gene nifD from representatives of subsections IV and V was performed by using maximum-likelihood criteria. The heterocystous cyanobacteria are supported as being monophyletic, with the non-heterocystous cyanobacteria as their closest relative. However, neither subsection IV nor subsection V is monophyletic, with representatives of both subsections intermixed in two sister clades. Analysis of nifD does not support recognition of two distinct subsections.
