Genomic Epidemiology and Antimicrobial Resistance Profiles of from Multi-Hospitals in a City in Eastern China.

Background: is an important pathogen causing approximately 20-30% of the cases-with antibiotic-associated diarrhea and 90% of those with . However, limited surveillance of infections (CDI) in China is done at present, especially in terms of multi-hospital epidemiological reports.

Methods: Between June 2020 and November 2020, we conducted a prospective study addressing antimicrobial susceptibility profiles and genomic epidemiology of strains isolated from inpatients with diarrhea in seven tertiary hospitals in the same city.

Adsorption-reduction removal of Cr(VI) by tobacco petiole pyrolytic biochar: Batch experiment, kinetic and mechanism studies.

Tobacco petiole biochar (TPBC) was prepared via pyrolysis and used for Cr(VI) removal. Cr(VI) removal efficiency was reduced by pyrolytic temperature (PyT) increase which mainly affected by functional groups rather than specific surface area. According to the optimal pseudo second-order kinetic, the initial adsorption rate was decreased with PyT increase from 355.
