Aims: This study aims to identify and address significant limitations in current culture-based regulatory methods used for monitoring microbiological water quality. Specifically, these methods' inability to distinguish between planktonic forms and aggregates containing higher bacterial loads and associated pathogens may lead to a severe underestimation of exposure risks, with critical public health implications.
Methods And Results: We employed a novel methodology combining size fractionation with ALERT (Automatic Lab-in-a-vial E.

Article Synopsis
- * A total of 531 saliva samples were analyzed from two Tribal Nation festivals and compared with 453 samples previously collected in the Midwest, employing logistic and linear regression models.
- * Results indicated varying seroprevalences of specific infections, with higher antibody responses to certain noroviruses and unique associations between lifestyle factors (like water consumption and animal contact) and infection rates in the Tribal populations.
Implications of Lead (Pb)-Induced Transcriptomic and Phenotypic Alterations in the Aged Zebrafish ().

Department of Environmental and Global Health, University of Florida, 1225 Center Drive, Gainesville, FL 32610, USA.
Lead (Pb) is a well-known neurotoxin with established adverse effects on the neurological functions of children and younger adults, including motor, learning, and memory abilities. However, its potential impact on older adults has received less attention. Using the zebrafish model, our study aims to characterize the dose-response relationship between environmentally relevant Pb exposure levels and their effects on changes in behavior and transcriptomics during the geriatric periods.

According to the World Health Organization, climate change is one of the top 10 health threats facing humanity. No aspect of adolescent health is spared from the consequences of climate change: food and housing insecurity, heat-related morbidity and mortality, water-borne diseases, infectious diseases, including sexually transmitted infections and HIV, mental health disorders, gender-based violence, conflict, internal displacement, and migration are all impacted.

The efficacy of herbal supplements in mitigating heavy metals (HMs) toxicity was investigated using a widely grown fish, the Nile tilapia (Oreochromis niloticus). The experiment was conducted over two phases: during the stress phase, the experimental fishes were exposed to sub-lethal concentrations of HMs, including lead, cadmium, zinc, and copper for 15 days; following which during the feeding phase, herbal supplements were given for 70 days to ameliorate their effects. Seven groups were established: the control negative group (CON-ve), control positive group (CON+ve, without any treatment), and five groups with supplementation of 1% turmeric (TUR), cinnamon (CIN), ginger (GIN), garlic (GAR), and their mixture (MIX), respectively.
