Project description:We report a case of Massilia varians isolated from a deep finger wound following orthopedic surgery on an immunocompetent patient. The bacterium was identified by 16S rDNA sequence analysis. This is the first case of M. varians isolated from a clinical specimen since the first report in 2008.

Project description:From farmed corn soil in California, we isolated and sequenced a new member of the genus Massilia, Massilia sp. strain MC02. Massilia sp. MC02 has an assembled draft genome of 5,023,356?bp with a total of 4,790 protein-encoding genes and 3,028 predicted proteins, 47 tRNA genes, and 2 rRNA operons.

Project description:BACKGROUND: Ecologically meaningful classification of bacterial populations is essential for understanding the structure and function of bacterial communities. As in soils, the ecological strategy of the majority of root-colonizing bacteria is mostly unknown. Among those are Massilia (Oxalobacteraceae), a major group of rhizosphere and root colonizing bacteria of many plant species. METHODOLOGY/PRINCIPAL FINDINGS: The ecology of Massilia was explored in cucumber root and seed, and compared to that of Agrobacterium population, using culture-independent tools, including DNA-based pyrosequencing, fluorescence in situ hybridization and quantitative real-time PCR. Seed- and root-colonizing Massilia were primarily affiliated with other members of the genus described in soil and rhizosphere. Massilia colonized and proliferated on the seed coat, radicle, roots, and also on hyphae of phytopathogenic Pythium aphanidermatum infecting seeds. High variation in Massilia abundance was found in relation to plant developmental stage, along with sensitivity to plant growth medium modification (amendment with organic matter) and potential competitors. Massilia absolute abundance and relative abundance (dominance) were positively related, and peaked (up to 85%) at early stages of succession of the root microbiome. In comparison, variation in abundance of Agrobacterium was moderate and their dominance increased at later stages of succession. CONCLUSIONS: In accordance with contemporary models for microbial ecology classification, copiotrophic and competition-sensitive root colonization by Massilia is suggested. These bacteria exploit, in a transient way, a window of opportunity within the succession of communities within this niche.

Project description:A new virus was isolated from three independent pools of Phlebotomus perniciosus sandflies (Diptera; Psychodidae) trapped in two regions of southeastern France, located 90 miles apart. Microscopic, antigenic and genetic analyses indicate that this novel virus belongs to the genus Phlebovirus in the family Bunyaviridae. The new virus is designated Massilia virus since the first isolate was obtained from sandflies collected in the suburban area of Marseille. The complete genome sequence was determined and used to compare the genetic and phylogenetic relationships of Massilia virus with other phleboviruses. Genetic and antigenic properties were employed to address whether or not Massilia virus should be considered a new species within the genus, or a member of a previously recognized species. Cerebrospinal fluid specimens, collected from local patients with central nervous system infections during the previous four-year period were tested for the presence of Massilia virus RNA, but gave negative results. In conclusion, Massilia virus is proposed as a member of the Sandfly fever Naples virus complex; its public health importance has yet to be determined.

Project description:This study describes the molecular phylogeny, laboratory rearing, and karyotype of a bombycid moth, Trilocha varians (F. Walker) (Lepidoptera: Bombycidae), which feeds on leaves of Ficus spp. (Rosales: Moraceae). The larvae of this species were collected in Taipei city, Taiwan, and the Ryukyu Archipelago (Ishigaki and Okinawa Islands, Japan). Molecular phylogenetic analyses revealed that T. varians belongs to the subfamily Bombycinae, thus showing a close relationship to the domesticated silkworm Bombyx mori (L.), a lepidopteran model insect. A laboratory method was developed for rearing T. varians and the time required for development from the embryo to adult was determined. From oviposition to adult emergence, the developmental zero was 10.47 °C and total effective temperature was 531.2 day-degrees, i.e., approximately 30 days for one generation when reared at 28 °C. The haploid of T. varians consisted of n = 26 chromosomes. In highly polyploid somatic nuclei, females showed a large heterochromatin body, indicating that the sex chromosome system in T. varians is WZ/ZZ (female/male). The results of the present study should facilitate the utilization of T. varians as a reference species for B. mori, thereby leading to a greater understanding of the ecology and evolution of bombycid moths.

Project description:Massilia sp. are aerobic, Gram-negative, rod-shaped bacteria that are found in air, water, and soils. Here we describe the draft genome sequence of Massilia sp. KIM, isolated from the South African grassland soils. The total length of the genome was estimated at 5.73 Mb, comprised of 17 contigs. The draft genome has been deposited in the DDBJ/EMBL/GenBank under the accession MVAD10000000 and is available for download at: https://www.ncbi.nlm.nih.gov/nuccore/MVAD00000000. Additionally, the raw short reads are available in the NCBI SRA database under the accession number: SRR5469241.

Project description:Massilia sp. strain Mn16-1_5 was isolated from serpentine soil. This strain is able to oxidize manganese and has the potential for bioremediation of chromium. Here, we present a 5.53-Mb draft genome sequence of this strain with a G+C content of 64.8% that might provide more information for species delineation and oxidase genes in this strain.

Project description:1. An enzyme similar to mammalian acetylcholinesterase is found in high activity in the nervous tissue of Palaemonetes varians, i.e. eyes plus stalks, brain, suboesophageal ganglion and ventral cord. Acetylcholinesterase is also found associated with the abdominal muscles. Multiple enzyme forms are found in extracts of nervous tissues and muscles by electrophoresis and isoelectric focusing. 2. Cholinesterase is present in high activity in the stomatogastric system of P. varians. Three electrophoretically separable forms are found, having isoelectric points at pH4.2, 4.5 and 5.4. 3. Approx. 50% of the total acetylcholinesterase activity, approx. 80% of the choline acetyltransferase activity and 100% of the acetylcholine equivalents are found associated with the nervous tissue. Among the tissues examined, eyes plus stalks were the richest source of both choline acetyltransferase and acetylcholine equivalents. Suboesophageal ganglion and brain also contained large amounts of these components. 4. The distribution of these components could support the function of acetylcholine as a central and/or sensory transmitter in P. varians.
