Abstract:
... We performed a comprehensive safety assessment of a probiotic based on the whole genome sequence and corresponding phenotypes. This was performed on Lactobacillus plantarum JDM1, a widely used commercial probiotic strain in China. The minimal inhibitory concentrations (MICs) of sixteen antibiotics and the biogenic amine production of JDM1 were tested to supplement a traditional oral toxicity test. ...

Abstract:
... Antibiotic residues in surface soils can lead to serious health risks and ecological hazards. Spatial mean concentration of antibiotic residues in the soil is the most important indicator of a region's environmental risk to antibiotic residues. Considerable estimation error would lead to an inefficient strategy of pollution control that happens when sample size is small and the estimation model do ...

Abstract:
... Edwardsiella tarda is a Gram-negative intracellular pathogen accounting for enormous economic losses in cultured seawater and freshwater fish. Infection by E. tarda often leads to the development of a systematic disease called edwardsiellosis, characterized by symptoms of ascites, hernia, exophthalmia, and severe lesions of internal organs. Although edwardsiellosis has been studied for many years, ...

Abstract:
... Earlier, we reported that ST239 was the 15-year predominant methicillin-resistant Staphylococcus aureus (MRSA) clone in China. In this study, MRSA strain CN79 belonging to ST239 and isolated from blood was used to determine the whole genome sequence. Comparative genomics analysis was done between MRSA CN79 and 25 sequenced S. aureus in the NCBI GenBank database. A total of 2,734 protein-encoding g ...

Abstract:
... Enterococcus is a major cause of important nosocomial infections. Linezolid, the first member of an entirely new class of antibiotics (oxazolidinones), is effective against serious infections caused by Enterococcus. However, resistance to linezolid has been discovered throughout the world rapidly. From 2011 to 2013, nine linezolid-resistant E. faecalis isolates were collected and the possible mech ...
