Article Abstract
Mosquitoes are major infectious disease-carrying vectors. Assessment of current and future risks associated with the mosquito population requires knowledge of the full repertoire of pathogens they carry, including novel viruses, as well as their blood meal sources. Unbiased metatranscriptomic sequencing of individual mosquitoes offers a straightforward, rapid, and quantitative means to acquire this information. Here, we profile 148 diverse wild-caught mosquitoes collected in California and detect sequences from eukaryotes, prokaryotes, 24 known and 46 novel viral species. Importantly, sequencing individuals greatly enhanced the value of the biological information obtained. It allowed us to (a) speciate host mosquito, (b) compute the prevalence of each microbe and recognize a high frequency of viral co-infections, (c) associate animal pathogens with specific blood meal sources, and (d) apply simple co-occurrence methods to recover previously undetected components of highly prevalent segmented viruses. In the context of emerging diseases, where knowledge about vectors, pathogens, and reservoirs is lacking, the approaches described here can provide actionable information for public health surveillance and intervention decisions.

Background: Acinetobacter seifertii, a recently identified member of the Acinetobacter calcoaceticus-Acinetobacter baumannii (Acb) complex, has emerged as a cause of severe human infections. It is closely related to Acinetobacter nosocomialis, a major pathogen of the Acb complex. Here, we aimed to explore the clinical and molecular differences between these two species.

The global spread of antimicrobial resistance (AMR) poses a serious threat to public health, with hospital wastewater treatment plants (WWTPs) recognized as a key hotspot for resistant pathogens and antibiotic resistance genes (ARGs). This study employed advanced hybrid sequencing platforms to provide a comprehensive resistomic analysis of a Qingdao WWTP in China, revealing previously uncovered AMR transmission risks. We identified 175 ARG subtypes conferring resistance to 38 antimicrobials, including the last-resort antibiotics, highlighting the extensive and concerning resistance reservoir within this environment.

Cattle are a reservoir for the zoonotic human foodborne pathogen Shiga toxin-producing Escherichia coli (STEC), the causative agent of many disease outbreaks associated with contaminated fresh leafy greens. Concentrated animal feeding operations (CAFOs) housing cattle generate fugitive dust, however the potential risk of STEC movement by means of the aerosolized dust is not well known. In this investigation, we used metagenome sequencing of air samples collected in an agricultural setting to investigate airborne transfer of STEC from a large CAFO to the surrounding area.

Livestock wastewater is a critical reservoir of antibiotic resistance genes (ARGs) that poses significant public health risks. This study comprehensively evaluated the seasonal dynamics and associated risks of ARGs in a full-scale livestock wastewater treatment plant using an integrated metagenomic and metatranscriptomic approach. The results showed that untreated livestock wastewater harbored high abundance (4.

LP-98 is a lipopeptide HIV fusion inhibitor showing strong treatment and pre-exposure prophylaxis efficacies in non-human primates. In this study, we further characterized its pharmacokinetics, long-lasting antiviral activity, and post-exposure prophylaxis (PEP) efficacy using 62 macaques. In cynomolgus macaques, LP-98 achieved high concentrations (C) with a half-life (T) of ∼31 h, and sustained an effective therapeutic concentration for two weeks post-injection.
