The detection of virus RNA in wastewater has been established as a valuable method for monitoring Coronavirus disease 2019. Carbon nanomaterials hold potential application in separating virus RNA owing to their effective adsorption and extraction capabilities. However, carbon nanomaterials have limited separability under homogeneous aqueous conditions.

is recognized as one of the primary pathogens responsible for foodborne illnesses. The ability of to form biofilms notably increases its resistance to antibiotics such as ampicillin and tetracycline, making it exceedingly difficult to eradicate. Residual bacteria within the processing environment can contaminate food products, thereby posing a significant risk to public health.

Background: Enteric fever is a great public health problem associated with significant illness and death in many endemic countries, and its clinical diagnosis is still daunting. The aim of this study was to determine the prevalence and risk factors of Typhi among febrile patients in Bafoussam and to evaluate the diagnostic performances of Widal and Typhidot tests.
Methods: This was a cross-sectional study among 336 participants visiting three hospitals in Bafoussam from August 1, 2021, to November 31, 2021.

Considering the lack of detailed research on the antibacterial mechanism of polyoxometalates, we examined the synergistic effect of novel bulky mixed Ti/W hetero-polyoxometalates (KH ［α-GeTiWO］・ 29HO; αTi4, KH ［α-GeTiWO］・16HO; αTi6, KH［α-GeTiWO］・39HO; αTi12, KH ［β-GeTiWO］・ 45HO; βTi6) with the antibiotic oxacillin against vancomycin intermediate-resistant Staphylococcus aureus (VISA) using fractional inhibitory concentration (FIC) index and growth curve in this study. All polyoxometalates used in this study showed remarkable synergistic effects with oxacillin. Its synergistic antibacterial mechanism was examined using reverse transcription PCR (RT-PCR) and penicillin binding protein-2' (PBP2') latex agglutination test.

Salivary innate defenses encompass mechanical cleaning, calcium phosphate salts and fluoride ion reduction of enamel dissolution rate, buffering capacity and neutralizing capacity, and antibacterial properties employing antimicrobial substances like antimicrobial peptides,agglutins,lactoferrin, lactoperoxidase, lysozyme and immuno globulins. Antimicrobial peptides play a key role in the initial defensive responses that make up innate immunity. The aim of this study was to assess the relationship between salivary physicochemical characteristics like buffering capacity, pH, flow rate, and concentrations antimicrobial human peptide like HBD-3, HNP1-3 and LL-37 and caries activity in young children.
