Abstract Staphylococcus aureus is a Gram-positive pathogen responsible for antibiotic-resistant infections. To identify vulnerabilities in cell envelope biogenesis that may overcome resistance, we enriched for S. aureus transposon mutants with defects in cell surface integrity or cell division by sorting for cells that stain with propidium iodide or have increased light-scattering properties, respectively. Transposon sequencing of the sorted populations identified more than 20 previously uncharacterized factors impacting these processes. Cells inactivated for one of these proteins, factor preventing extra Z-rings (FacZ, SAOUHSC_01855), showed aberrant membrane invaginations and multiple FtsZ cytokinetic rings. These phenotypes were suppressed in mutants lacking the conserved cell-division protein GpsB, which forms an interaction hub bridging envelope biogenesis factors with the cytokinetic ring in S. aureus . FacZ was found to interact directly with GpsB in vitro and in vivo. We ther

Overview Safe and readily available water is important for public health, whether it is used for drinking, domestic use, food production or recreational purposes. Improved water supply and sanitation, and better management of water resources, can boost countries' economic growth and can contribute greatly to poverty reduction. In 2010, the UN General Assembly explicitly recognized the human right to water and sanitation. Everyone has the right to sufficient, continuous, safe, acceptable, physically accessible and affordable water for personal and domestic use. Drinking-water services Sustainable Development Goal target 6.1 calls for universal and equitable access to safe and affordable drinking water. The target is tracked with the indicator of "safely managed drinking water services" – drinking water from an improved water source that is located on premises, available when needed, and free from faecal and priority chemical contamination. In 2022, 6 billion peopl

Norovirus cases are on the rise in the U.S. especially in the Northeast, the Centers for Disease Control and Prevention said. Norovirus, sometimes referred to as a "stomach flu" or "stomach bug," is a common virus that's highly contagious and spreads through tiny particles of feces or vomit and results in gastrointestinal symptoms. Many different noroviruses can cause illness, the CDC said. "Norovirus is a very contagious virus that causes vomiting and diarrhea. Anyone can get infected and sick with norovirus," the CDC explains. According to the most recent CDC data, more than 12% of tests for the virus came back positive in the week ending on Feb. 17. The week before that a little more than 11.5% of tests came back positive. The Northeast has seen a higher rate of norovirus cases. During the week ending on Feb. 24, more than 16% of tests came back positive, CDC data shows. Positivity rates in the Northeast have been more than 13% for the past

— OPINION — In the aftermath of the groundbreaking plea agreement with Family Dollar Stores LLC, entailing a fine and forfeiture totaling $41.675 million for storing food, drugs, medical devices, and cosmetics in unsanitary conditions, we are starkly reminded of the imperative for stringent regulatory enforcement within the domain of food safety. This agreement, representing the largest-ever monetary criminal penalty in the context of food safety, serves as a vivid indicator of the justice system's intensifying resolve in addressing such transgressions. This occasion necessitates reflection on historical incidents where the lack of such decisive actions had catastrophic outcomes, emphasizing the critical need for prompt and determined interventions. The 1993 E.coli outbreak linked to Jack in the Box restaurants stands as a harrowing instance. This tragedy, which resulted in the death of my son, Riley, along with three other children and afflicted more than 700 individuals acros

Norovirus, the highly contagious stomach bug which causes vomiting and diarrhea, is spreading in the United States. As the spring season begins, cases of norovirus continue to climb across the country, surging in certain regions. Respiratory virus activity may be slowing down in the U.S., but the 2023-2024 norovirus season is still well underway. Nationally, norovirus is circulating at the highest levels since last April, according to data from the U.S. Centers for Disease Control and Prevention. Norovirus, also known as the "stomach flu" or food poisoning, spreads easily among people in enclosed settings. As cases spike and thousands of Americans travel for spring break, U.S., public health officials are urging people to take precautions to stop the spread. Although norovirus is commonly called the "stomach flu," it is not related to the flu, which is caused by influenza viruses. Norovirus is a leading cause of acute gastroenteritis, or an inflammation of the linin

Abstract Background Chorioamnionitis alters neonatal immune responses. Gestational COVID-19 infection is associated with adverse pregnancy outcomes, but its impact on neonatal immunity is unclear. We hypothesized that gestational COVID-19 exposure would result in exaggerated neonatal immune responses, similar to chorioamnionitis-exposed neonates. Methods Term umbilical cord blood mononuclear cells (CBMCs) were isolated from neonates exposed to chorioamnionitis, gestational COVID-19 or unexposed controls. CBMCs were cultured and stimulated with heat-killed Escherichia coli , Streptococcus agalactiae or Staphylococcus epidermidis . A multiplexed protein assay was used to measure cytokine levels in cell culture supernatants and flow cytometry was used to evaluate cellular-level cytokine expression. Results Both chorioamnionitis-exposed and COVID-19 exposed CBMCs demonstrated upregulation of IL-1β and IL-6 compared to unexposed CBMCs, while only COVID-19 exposure resulted in IL-8 upregula
