Ram Hari Dahal, Jaisoo Kim
A novel casein hydrolysing bacterium designated strain S-52T was isolated from Kyonggi University forest soil. Cells were strictly aerobic, Gram stain-negative, oxidase- and catalase- positive, non-motile, non-spore-forming, rod-shaped, and golden-yellow-pigmented. Strain S-52T hydrolysed casein. It was able to grow at 20-37 °C (optimum 25-32 °C), pH 6.5-11.0 (optimum 7-9.5), and at 3% (w/v) NaCl concentration. Strain exhibits flexirubin-type pigments. Phylogenetic analysis based on 16S rRNA gene sequence revealed that strain S-52T formed a lineage within the genus Chitinophaga that was distinct from other species of the genus...

In this study, we report the design and fabrication of a novel biocompatible sponge with excellent antibacterial property, making it a promising material for wound dressings. The sponge is formed by grafting amoxicillin onto regenerated bacterial cellulose (RBC). It was observed that the grafted RBC could enhance the antibacterial activity against fungus, Gram-negative and Gram-positive bacteria. The morphology of strains treated with the grafted RBC and fluorescent stain results further demonstrated the antibacterial ability of the fabricated sponge...

Sunit Singhi, Suresh Kumar Angurana
CNS infections in children are medical emergency and are associated with high mortality and morbidity. For diagnosis, a high index of suspicion is required. Clinical assessment should be supplemented by laboratory investigations including CSF Gram stain and cultures, blood culture, PCR on CSF, serological tests, and imaging. Commonly associated life threatening complications include coma, seizure, raised intracranial pressure (ICP), focal deficits, shock, respiratory failure, and fluid and electrolyte abnormalities...

Bacterial strain B29T1T was isolated from the endophytic microbial community of a Pinus pinaster tree trunk and characterized. Strain B29T1T stained Gram-negative and formed diplococci that grew optimally at 26-30°C and at pH 6.0-7.0. The G+C content of the DNA was 61.6mol%. The respiratory quinone was ubiquinone 10 (UK-10), and the major fatty acids were C16:0, cyclo-C19:0ω8c and C18:0 12-methyl, representing 64% of the total fatty acids. Phylogenetic analyses based on the 16S rRNA gene sequences placed strain B29T1T within the order Rhodospirillales in a distinct lineage that also included the genus Geminicoccus...

Particularly in Asia medicinal plants with antimicrobial activity are used for therapeutic purpose. One such plant-derived antibiotic is rhodomyrtone (Rom) isolated from Rhodomyrtus tomentosa leaves. Rom shows high antibacterial activity against a wide range of Gram-positive bacteria, however, its mode of action is still unclear. Reporter gene assays and proteomic profiling experiments in Bacillus subtilis indicate that Rom does not address classical antibiotic targets like translation, transcription or DNA replication, but acts at the cytoplasmic membrane...

BACKGROUND: Methicillin-resistant Staphylococcus aureus (MRSA) infections continue to be a leading problem in health care facilities worldwide. METHODS: This single-center retrospective cohort study consisted of a derivation phase and a validation phase. The derivation phase included all patients admitted to Osaka University Hospital between May 2010 and April 2011. We proposed a provisional available, bed-sided, comprehensive (ABC) score, and evaluated its accuracy using the clinical diagnosis as a reference...

Pediatric septic arthritis can be a devastating disease. Often, the diagnosis can be challenging as autoimmune and infectious causes may present in a similar fashion. Thus, we present the case of a five-year-old male patient, from the Pacific coast of Colombia, with chronic morning knee pain and stiffness thought to be caused by an autoimmune disease. He presented with a mild effusion of the left knee, a flexed posture, and limited extension to 25°. Inflammatory markers demonstrated an infectious pattern. Autoimmune markers were negative...
