IJERPH, Vol. 17, Pages 1273: Microbiological Assessment of Tap Water Following the 2016 Louisiana Flooding International Journal of Environmental Research and Public Health doi: 10.3390/ijerph17041273 Authors: Phan Sherchan Floods are a prominent risk factor in the world of public health, as there is a risk of dispersal of harmful biological and chemical contaminants in floodwater. As climate change increases, the occurrence of natural disasters and risk of adverse health outcomes due to flash flooding also increases. Fecal indicator bacteria, such as Escherichia coli and Enterococci, are often encountered in contaminated floodwater and can cause gastrointestinal illnesses as well as a variety of infections. In August 2016, East Baton Rouge and surrounding parishes in Louisiana suffered heavy floods due to intense rainfall. No study of water quality during flooding has been conducted previously in Baton Rouge, Louisiana. Twenty-three pre-flush and post-flush water samples were collected immediately from accessible homes that had been affected by the floods in order to quantify concentrations of fecal indicator bacteria. These samples were analyzed for the presence of E. coli and Enterococci through both quantitative polymerase chain reaction (qPCR) and the IDEXX enzyme substrate method. The qPCR results indicated that 30% of the samples contained Enterococci and 61% of the samples contained E. coli, with the highest concentrations found in the pre-flush outdoor ho...

CONCLUSIONS: Arabinofuranose ‐derived18F PET radiotracers can be synthesized with high radiochemical purity. Our study showed absence of bacterial accumulation for 5 ‐substitued analogs, a finding that may have mechanistic implications for related tracers. Bothd‐2‐18F ‐AF andl‐2‐18F ‐AF showed sensitivity to most gram‐negative and gram‐positive organisms. Future in vivo studies will evaluate the diagnostic accuracy of these radiotracers in animal models of infection.

Conclusion: This study has a total complication rate of 16%, approximately 10% of those are severe. The most common complication to PCNL was infection (60%), followed by bleeding (5.4%), reoperation (1.6%) and pain (0.5%). The high prevalence of E. faecalis might need to be considered, however the results should be validated in a larger cohort, possibly with a higher rate of antibiotic resistance, before a change of guidelines regarding prophylactic antibiotics could be proposed.

In this study, we analyzed the epidemiological and genetic features of NoV outbreaks from July 2014 to June 2018 in Huzhou, China. A total of 450 stool samples collected from 51 AGE outbreaks were tested for NoVs by real-time RT PCR. Partial polymerase and capsid sequences of NoV-positive samples were amplified and sequenced for phylogenetic analysis. NoVs were found to be responsible of 84.3% of AGE outbreaks in Huzhou over the past 5 years. Most NoV outbreaks were reported in the cool months (November-March) and occurred in primary schools and kindergartens. Changes in the diversity of genotypes and the distribution of p...

Bacterial persisters are rare phenotypic variants that are temporarily tolerant to high concentrations of antibiotics. We have previously discovered that stationary-phase-cell subpopulations exhibiting high redox activities were less capable of producing proteins and resuming growth upon their dilution into fresh media. The redox activities of these cells were maintained by endogenous protein and RNA degradation, resulting in self-inflicted damage that transiently repressed the cellular functions targeted by antibiotics. Here, we showed that pretreatment of stationary-phase cells with an ATP synthase inhibitor, chlorpromaz...
