Municipal wastewater surveillance reveals high community disease burden of rarely reported and possibly subclinical Salmonella Derby strain.

This study demonstrates wastewater's capability to provide community infectious disease information - such as background infection rates of subclinical enteric illness - which is otherwise inaccessible through clinical approaches.IMPORTANCE Wastewater-based epidemiology (WBE) has been conventionally used to analyze community health via the detection of chemicals, such as legal and illicit drugs; however, municipal wastewater contains microbiological determinants of health and disease as well, including enteric pathogens. Here, we demonstrate that WBE can be used to examine subclinical community salmonellosis patterns. Derby was the most abundant Salmonella serovar detected in Hawaii wastewater over a year-long sampling study, with few corresponding clinical cases. Comparative genomics analyses indicate that the normally rare strain of S. Derby found in wastewater has a unique combination of genes which allow it to persist as a subclinical infection without producing symptoms of severe gastroenteritis. This study shows that WBE can be used to explore trends in community infectious disease patterns which may not be reflected in clinical monitoring, shedding light on overall enteric disease burden and rates of asymptomatic cases.

This study aimed to evaluate in vitro and in vivo the wound healing effects of babassu oil. In vitro, babassu oil increased the migration of L929 fibroblasts, inhibited the production of nitric oxide by LPS-stimulated peritoneal macrophages, and increased the levels of INF-γ and IL-6 cytokines production. In vivo, babassu oil accelerated the healing process in a full-thickness splinted wound model, by an increase in the fibroblasts number, blood vessels, and collagen deposition in the wounds. The babassu oil also increased the recruitment of inflammatory cells into the wound site and showed an anti-inflammatory effec...

Key messages Healthcare facilities, including long-term care facilities (LTCFs), should apply several types of measures to minimise the risk of transmission of COVID-19. The mainstays of infection prevention and control (IPC) in all healthcare facilities are administrative measures, physical distancing, hand hygiene and the appropriate use of personal protective equipment (PPE). Administrative measures decrease the opportunities for transmission within healthcare facilities and diminish the risk of outbreaks. In areas with community transmission of COVID-19, staff, visitors and patients should apply physical distancing, ha...
