Pseudomonas monteilii Kingdom: Bacteria Phylum: Proteobacteria Class: Gamma Proteobacteria Order: Pseudomonadales Family: Pseudomonadaceae Genus: Pseudomonas Species: Pseudomonas monteilii Elomari et al., 1997 Binomial name: Pseudomonas monteilii Elomari et al., 1997. Pseudomonas monteilii is a Gram-negative, rod- shaped, motile bacterium isolated from human bronchial aspirate (Elomari et al 1997). They are incapable of liquefing gelatin. They grow at 10°C but not at 41°C, produce fluorescent pigments, catalase, and cytochrome oxidase, and possesse the arginine dihydrolase system. They are capable of respiratory but not fermentative metabolism. (Masua et al 2007) Rhodococcus pyridinivorans Kingdom: Bacteria Phylum: Actinobacteria Class: Actinobacteria Order: Actinomycetales Family: Nocardiaceae Genus: Rhodococcus Species: Rhodococcus pyridinivorans Yoon et al., 2000 The cells are non-spore-forming, non-motile and Gram-positive, but are Gram-variable in old cultures. Substrate mycelia that are on the surface and penetrate into the agar media are visible and fragment into short rod-to-coccus elements. The cells are rods and branched filaments during the early growth phase and then fragment into short rods or cocci. Colonies are light orange in colour, opaque and raised with slightly irregular edges on TSA. Colonies have irregularly round wrinkles. Grows well over a broad pH range (6.0-9.0); the optimal pH range is 7.5-8.5. Grows optimally at 30-37 °C; growth occurs at 10 and 45 °C but does not occur at 50 °C. Catalase- and urease- positive. Oxidase- and DNase-negative. Arbutin, aesculin, Tween 80, tyrosine and urea are hydrolysed.

The organism that is the subject of this application is also the subject of: a. an innovative medicine application as defined in section 23A of the Medicines Act 1981. Yes No b. an innovative agricultural compound application as defined in Part 6 of the Agricultural Compounds and Veterinary Medicines Act 1997. Yes No 2. What evidence do you have that the organism was present in New Zealand immediately prior to 29 July 1998? Pseudomonas monteilii The genus Pseudomonas encompasses the most diverse and ecologically significant group of bacteria on earth. Members of the genus are found in all of the major natural environments (terrestrial, freshwater and marine) and also form associations with plants and animals. This universal distribution suggests a remarkable degree of physiological and genetic adaptability (Spiers et al. 2000). Pseudomonas is a genus with widespread occurrence in water and in plant seeds such as dicots. Many members of the genus have been reported in New Zealand, including Pseudomonas putida and Pseudomonas oryzihabitans (http://nzfungi2.landcareresearch.co.nz), which are taxonomically closely related with Pseudomonas monteilii. Pseudomonas monteilii is a versatile bacterium found in various niches (Remold et al. 2011). Pseudomonas monteilii strains are associated with degradation of aromatic and heterocyclic compounds. P. monteiliiis is an aspirate found in many international hospitals, and where organisms are carried by people, it is easy to argue that they have been carried in to NZ even if they haven’t been recorded. Some Pseudomonas monteilii strains were isolated from clinical specimens, yet no P. monteilii infection has been reported. The P. monteilii strains are phenotypically and genotypically homogeneous and can be differentiated from related nonphytopathogenic fluorescent members of section I of the genus Pseudomonas. May 2012 EPA0159 6 Application to determine if an organism is a new organism The clinical significance of P. monteilii is not known. Future isolates of this new organism should be investigated to determine their role in nosocomial infections. At present, it is hypothesized that P. monteilii is a rare opportunistic pathogen or colonizer. Pseudomonas spp. are ubiquitous in the environment. As opportunistic pathogens, some Pseudomonas spp. could invade the host tissue and cause infection and bacteremia in immunocompromised hosts. P. aeruginosa is the most common agent associated with infection and inflammation during contact lens wear. Other Pseudomonas species are also opportunistic; however, cases of infection are rare. Rhodococcus pyridinivorans Members of Rhodococcus have been found to thrive in a broad range of environments, including soil, water, and eukaryotic cells. Several species of the genus have been found in New Zealand, such as Rhodococcus equi, Rhodococcus fascians, and Rhodococcus rhodochrous (http://nzfungi2.landcareresearch.co.nz) Members of the genus Rhodococcus are mostly soil saprophytes although they are common in many environments, and a large number of them are known as toxic-material decomposing strains. Rhodococcus pyridinivorans was originally isolated as an extremely efficient pyridine-degrading coryneform bacterium from industrial wastewater in Korea The species R. pyridinivorans comprises strains that are metabolically versatile and are able to degrade numerous aromatic compounds. The pathogenicity of the bacteria that belonged to Rhodococcus was investigated based on information from the literature. Previous reports revealed that R. equi and R. facians are

  • Physiology of Dimethylsulfoniopropionate Metabolism
    PHYSIOLOGY OF DIMETHYLSULFONIOPROPIONATE METABOLISM IN A MODEL MARINE ROSEOBACTER, Silicibacter pomeroyi by JAMES R. HENRIKSEN (Under the direction of William B. Whitman) ABSTRACT Dimethylsulfoniopropionate (DMSP) is a ubiquitous marine compound whose degradation is important in carbon and sulfur cycles and influences global climate due to its degradation product dimethyl sulfide (DMS). Silicibacter pomeroyi, a member of the a marine Roseobacter clade, is a model system for the study of DMSP degradation. S. pomeroyi can cleave DMSP to DMS and carry out demethylation to methanethiol (MeSH), as well as degrade both these compounds. Dif- ferential display proteomics was used to find proteins whose abundance increased when chemostat cultures of S. pomeroyi were grown with DMSP as the sole carbon source. Bioinformatic analysis of these genes and their gene clusters suggested roles in DMSP metabolism. A genetic system was developed for S. pomeroyi that enabled gene knockout to confirm the function of these genes.

  • Comparison of Physiology and Genome-Wide Expression in Two Nitrosomonas Spp
    Comparison of physiology and genome-wide expression in two Nitrosomonas spp. under batch cultivation By Mohammad Ghashghavi A thesis submitted in partial fulfillment of the requirements for the degree of Master of Science In Microbiology and Biotechnology Department of Biological Sciences University of Alberta © Mohammad Ghashghavi, 2014 Abstract: Ammonia oxidizing bacteria (AOB) play a central role in the nitrogen cycle by oxidizing ammonia to nitrite. Nitrosomonas europaea ATCC 19718 has been the single most studied AOB that has contributed to our understanding of chemolithotrophic ammonia oxidation. As a closely related species, Nitrosomonas eutropha C91 has also been extensively studied. Both of these bacteria are involved in wastewater treatment systems and play a crucial part in major losses of ammonium-based fertilizers globally. Although comparative genome analysis studies have been done before, change in genome-wide expression between closely related organisms are scarce. In this study, we compared these two organisms through physiology and transcriptomic experiments during exponential and early stationary growth phase. We found that under batch cultivation, N. europaea produces more N2O while N. eutropha consumes more nitrite. From transcriptomic analysis, we also found that there are selections of motility genes that are highly expressed in N. eutropha during early stationary growth phase and such observation was completely absent in N. europaea. Lastly, principle homologous genes that have been well studied had different patterns of expression in these strains. This study not only gives us a better understanding regarding physiology and genome-wide expression of these two AOB, it also opens a wide array of opportunities to further our knowledge in understanding other closely related species with regards to their evolution, physiology and niche preference.

  • Characterization of Bacterial Communities Associated
    www.nature.com/scientificreports OPEN Characterization of bacterial communities associated with blood‑fed and starved tropical bed bugs, Cimex hemipterus (F.) (Hemiptera): a high throughput metabarcoding analysis Li Lim & Abdul Hafz Ab Majid* With the development of new metagenomic techniques, the microbial community structure of common bed bugs, Cimex lectularius, is well‑studied, while information regarding the constituents of the bacterial communities associated with tropical bed bugs, Cimex hemipterus, is lacking. In this study, the bacteria communities in the blood‑fed and starved tropical bed bugs were analysed and characterized by amplifying the v3‑v4 hypervariable region of the 16S rRNA gene region, followed by MiSeq Illumina sequencing. Across all samples, Proteobacteria made up more than 99% of the microbial community. An alpha‑proteobacterium Wolbachia and gamma‑proteobacterium, including Dickeya chrysanthemi and Pseudomonas, were the dominant OTUs at the genus level. Although the dominant OTUs of bacterial communities of blood‑fed and starved bed bugs were the same, bacterial genera present in lower numbers were varied. The bacteria load in starved bed bugs was also higher than blood‑fed bed bugs. Cimex hemipterus Fabricus (Hemiptera), also known as tropical bed bugs, is an obligate blood-feeding insect throughout their entire developmental cycle, has made a recent resurgence probably due to increased worldwide travel, climate change, and resistance to insecticides1–3. Distribution of tropical bed bugs is inclined to tropical regions, and infestation usually occurs in human dwellings such as dormitories and hotels 1,2. Bed bugs are a nuisance pest to humans as people that are bitten by this insect may experience allergic reactions, iron defciency, and secondary bacterial infection from bite sores4,5.

  • Horizontal Operon Transfer, Plasmids, and the Evolution of Photosynthesis in Rhodobacteraceae
    The ISME Journal (2018) 12:1994–2010 https://doi.org/10.1038/s41396-018-0150-9 ARTICLE Horizontal operon transfer, plasmids, and the evolution of photosynthesis in Rhodobacteraceae 1 2 3 4 1 Henner Brinkmann ● Markus Göker ● Michal Koblížek ● Irene Wagner-Döbler ● Jörn Petersen Received: 30 January 2018 / Revised: 23 April 2018 / Accepted: 26 April 2018 / Published online: 24 May 2018 © The Author(s) 2018. This article is published with open access Abstract The capacity for anoxygenic photosynthesis is scattered throughout the phylogeny of the Proteobacteria. Their photosynthesis genes are typically located in a so-called photosynthesis gene cluster (PGC). It is unclear (i) whether phototrophy is an ancestral trait that was frequently lost or (ii) whether it was acquired later by horizontal gene transfer. We investigated the evolution of phototrophy in 105 genome-sequenced Rhodobacteraceae and provide the first unequivocal evidence for the horizontal transfer of the PGC. The 33 concatenated core genes of the PGC formed a robust phylogenetic tree and the comparison with single-gene trees demonstrated the dominance of joint evolution. The PGC tree is, however, largely incongruent with the species tree and at least seven transfers of the PGC are required to reconcile both phylogenies. 1234567890();,: 1234567890();,: The origin of a derived branch containing the PGC of the model organism Rhodobacter capsulatus correlates with a diagnostic gene replacement of pufC by pufX. The PGC is located on plasmids in six of the analyzed genomes and its DnaA- like replication module was discovered at a conserved central position of the PGC. A scenario of plasmid-borne horizontal transfer of the PGC and its reintegration into the chromosome could explain the current distribution of phototrophy in Rhodobacteraceae.
