Mycolicibacterium smegmatis is a non-pathogenic model that is widely used to study core mycobacterial metabolism. This thesis explores mycobacterial pathways of cysteine biosynthesis by generating and study of genetic mutants of M. smegmatis. Published in vitro biochemical studies had revealed three independent routes to cysteine synthesis in mycobacteria involving separate homologs of cysteine synthase, namely CysK1, CysK2, and CysM. -

The strains were distinguished phenotypically from other known plant pathogenic pseudomonads. The watermelon bacterium was aerobic. Cells were rod-shaped, gram negative, and motile by means of a single polar flagellum. They were nonfluorescent and grew at 41°C but not at 4°C. Oxidase production and the 2- ketogluconate reaction were positive. The 10 strains utilized p-alanine, rA-leucine, D-serine, n-propanal, ethanol, ethanolamine, citrate, and fructose for growth. No growth occurred with sucrose or glucose. Their deoxyribonucleic acid base com- position was 66 1mol% guanine plus cytosine. The bacterium is phenotypically similar to P. pseudoalcaligenes but differs from it in being pathogenic to water- melon, Cucumis melo (cantaloupe), Cucumis sativus (cucumber), and Cucurbita pep0 (squash). The name P. pseudoalcaligenes subsp. citrulli is proposed for the new subspecies, of which strain C-42 (= ATCC 29625) is the type strain. -

One ecosystem service that has garnered recent attention is the ability of oysters to sequester impurities and nutrients, such as nitrogen (N), from the estuarine water that feeds them, via their exceptional filtration mechanism coupled with microbially-mediated denitrification processes. It is the oyster-associated microbiomes that essentially provide these myriads of ecological functions, yet not much is known on these microbiota at the genomic scale, especially from warm temperate and tropical water habitats. Among the suite of bacterial genera that appear to interplay with the oyster host species, pseudomonads deserve further assessment because Citation: Pathak, A.; Stothard, P.; of their immense metabolic and ecological potential. To obtain a comprehensive understanding on Chauhan, A. Comparative Genomic this aspect, we previously reported on the isolation and preliminary genomic characterization of Analysis of Three Pseudomonas Species three Pseudomonas species isolated from minced oyster tissue (P. -

Mycobacterium sp.Spyr1 is a newly isolated strain that occurs in a creosote contaminated site in Greece. It was isolated by an enrichment method using pyrene as sole carbon and energy source and is capable of degrading a wide range of PAH substrates including pyrene, fluoran- thene, fluorene, anthracene and acenapthene. Here we describe the genomic features of this organism, together with the complete sequence and annotation. -
Bordetella Trematum Infection: Case Report and Review of Previous Cases
y Castro et al. BMC Infectious Diseases (2019) 19:485 https://doi.org/10.1186/s12879-019-4046-8 CASEREPORT Open Access Bordetella trematum infection: case report and review of previous cases Thaís Regina y Castro1, Roberta Cristina Ruedas Martins2, Nara Lúcia Frasson Dal Forno3, Luciana Santana4, Flávia Rossi4, Alexandre Vargas Schwarzbold1, Silvia Figueiredo Costa2 and Priscila de Arruda Trindade1,5* Abstract Background: Bordetella trematum is an infrequent Gram-negative coccobacillus, with a reservoir, pathogenesis, a life cycle and a virulence level which has been poorly elucidated and understood. Related information is scarce due to the low frequency of isolates, so it is important to add data to the literature about this microorganism. Case presentation: We report a case of a 74-year-old female, who was referred to the hospital, presenting with ulcer and necrosis in both legs. Therapy with piperacillin-tazobactam was started and peripheral artery revascularization was performed. During the surgery, a tissue fragment was collected, where Bordetella trematum, Stenotrophomonas maltophilia, and Enterococcus faecalis were isolated. After surgery, the intubated patient was transferred to the intensive care unit (ICU), using vasoactive drugs through a central venous catheter. Piperacillin- tazobactam was replaced by meropenem, with vancomycin prescribed for 14 days. Four days later, levofloxacin was added for 24 days, aiming at the isolation of S. maltophilia from the ulcer tissue. The necrotic ulcers evolved without further complications, and the patient’s clinical condition improved, leading to temporary withdrawal of vasoactive drugs and extubation. Ultimately, however, the patient’s general condition worsened, and she died 58 days after hospital admission. -
