Publication date: December 2019Source: Microbial Pathogenesis, Volume 137Author(s): Seok Hyeon Na, Man Hwan Oh, Hyejin Jeon, Yun-Ki Lee, Byungheon Lee, Minsang Shin, Je Chul LeeAbstractBioluminescence imaging is a non-invasive tool for in vivo real-time monitoring of infectious disease progression in animal models. However, no bioluminescence imaging assay has been developed to monitor Acinetobacter baumannii infections. In the current study, bioluminescent strains of A. baumannii ATCC 17978 and its isogenic ΔompA mutant were constructed by integrating the promoter of the ompA gene and the luxCDABE luciferase gene in...

This study investigated the evolution of bacterial communities in the water–sediment systems under the influence of three typical velocity conditions with the timescale of 5 weeks. The results demonstrated that higher bacterial diversity and notable differences were detected in sediment compared to water using the 16S rRNA gene sequencing. The phyla Firmicutes and γ-Proteobacteria survived better in both water and sediment under stronger water disturbances. Their relative abundance peaked at 36.0%, 33.2% in water and 38.0%, 43.6% in sediment, respectively, while the phylum Actinobacteria in water had th...

The highly infectious bacteria can survive treatment at local sewage plants and enter the food chain of surrounding populations, the study revealed Researchers at the University of Edinburgh (UE) in Scotland found large amounts of antimicrobial-resistance (AMR) genes in hospital wastewater. These findings will be of interest to microbiologists and clinical laboratory managers, as the […]

Abstract Bioremediation methods have been successfully applied to the removal of organic pollutants for decades, but the responses of the microbial community to environmental factors remain less well known. In this work, the degradation rates of petroleum hydrocarbons (PHs) reached up to 50.11% ± 2.74% after optimizing the degradation conditions. Under the influence of the optimized degradation conditions, the diversity of the bacterial community gradually increased. Meanwhile, the dominant bacterial genera, encompassing Burkholderia-Paraburkholderia, Luteibacter, and Acinetobacter, remained s...

Abstract Thoracic injury is common on the battlefield and in terrorist attacks, occurring in 10-70% of patients depending on the type of weapons used. Typical injuries seen include bullet, blast and fragment injuries to the thorax which are often associated with injuries to other parts of the body. Initial management pre-hospital and in the emergency department is carried out according to the principles of Tactical Combat Casualty Care or other standard trauma management systems. Immediately life threatening problems including catastrophic hemorrhage are dealt with rapidly and early consideration given to computed...

37662RM1 and 37662RM2 are two phenotypically different, carbapenem-resistant mutants of Acinetobacter baumannii 37662 isolate following selection with meropenem (MEM) at sub-inhibitory concentrations. 37662RM2 lacks capsule synthesis and shows dramatically increased biofilm formation, while 37662RM1 shows merely impaired capsule synthesis. Here we report that 37662RM1 and RM2 have transcription profiles that are different from those of their starting strain, 37662WT. There were far more differentially expressed genes in 37662RM2 than in 37662RM1. The capsule polysaccharide (CPS) synthesis-required genes (itrA2, gtr5, psaA,...

In this study, the indigenous QQ bacterium Bacillus cereus HG10 was immobilized and used to control biofouling in a bioreactor. QQ beads caused extracellular polymeric substance reduction and significantly hindered biofilm formation on a submerged membrane. Community profiling of 16S rRNA gene amplicons revealed that QQ beads dramatically altered the bacterial community structure in activated sludge but not in biofilm. Bacterial structure in the presence of QQ beads showed a clear divergence from that of the control groups at phylum, class, order, family, and genus taxonomic ranks. A significant enrichment of several bacte...
