Black Creek Canal (BCC) virus is a hantavirus associated with hantavirus pulmonary syndrome in southeastern North America. The virus was isolated from the spleen of a cotton rat (Sigmodon hispidus) trapped in southern Florida. Our previous studies have shown that we could consistently infect male cotton rats with BCC virus in the laboratory. These animals became persistently infected and virus could be detected in salivary glands, urine, and feces. In this report we show: (1) female and male cotton rats are equally susceptible to BCC virus infection, (2) susceptibility to infection was not influenced by age, (3) all inoculated rats transmitted the infection to uninoculated cage mates, and (4) offspring of infected rats became infected despite the presence of high maternal antibodies. The course of BCC virus infection, as determined by antibody response and the ability to isolate or detect virus, appeared to be similar regardless of whether the rats obtained their infection by inoculation or contact with inoculated rats.

Setting up a global SARS-CoV-2 surveillance system requires an understanding of how virus isolation and propagation practices, use of animal or human sera, and different neutralisation assay platforms influence assessment of SARS-CoV-2 antigenicity. In this study, with the contribution of 15 independent laboratories across all WHO regions, we carried out a controlled analysis of neutralisation assay platforms using the first WHO International Standard for antibodies to SARS-CoV-2 variants of concern (source: NIBSC). Live virus isolates (source: WHO BioHub or individual labs) or spike plasmids (individual labs) for pseudovirus production were used to perform neutralisation assays using the same serum panels.

Article Synopsis
- This study examines the prevalence of co-infections with Burkholderia cepacia complex (Bcc) in patients with respiratory infections like COVID-19 and H7N9, highlighting a lack of previous research on this topic.
- A total of 49 Bcc isolates were analyzed from patients, revealing that those infected with COVID-19 had a higher rate of multidrug resistance and a shorter median lethal time compared to those with H7N9.
- The findings suggest that COVID-19-Bcc may have evolved from H7N9-Bcc, demonstrating increased virulence and antibiotic resistance in the context of respiratory infections.

The continued emergence of SARS-CoV-2 variants and the threat of future Sarbecovirus zoonoses have spurred the design of vaccines that can induce broad immunity against multiple coronaviruses. Here, we use computational methods to infer ancestral phylogenetic reconstructions of receptor binding domain (RBD) sequences across multiple Sarbecovirus clades and incorporate them into a multivalent adenoviral-vectored vaccine. Mice immunized with this pan-Sarbecovirus vaccine are protected in the upper and lower respiratory tracts against infection by historical and contemporary SARS-CoV-2 variants, SARS-CoV, and pre-emergent SHC014 and Pangolin/GD coronavirus strains.

Article Synopsis
- The rise of multidrug-resistant bacteria poses a serious threat to public health and impacts modern medicine, particularly affecting individuals with chronic illnesses like cystic fibrosis.
- Researchers isolated and characterized a temperate phage called vB_BceM_CEP1 from sewage, which belongs to the Peduoviridae family and shows promise in combating antimicrobial resistance due to its environmental stability and ability to disrupt biofilms.
- The phage's genome was analyzed and found to be 32,486 base pairs long with no genes related to antibiotic resistance or virulence, suggesting it might be a potential therapeutic tool against infections caused by the Burkholderia cepacia complex.
Orange-fleshed sweetpotato varieties that mature and harvest sooner play an important role in addressing food and nutrition demands in areas where irregular rainfall makes sustainable production challenging. A national variety trial was conducted in 2021 and 2022 during the main cropping season using ten OFSP genotypes in three locations in Sidama, South, and Oromia regions of Ethiopia, namely Hawassa, Arbaminch, and Koka, respectively. The objective of this study was to develop and select early-maturing and high-yielding OFSP genotypes for short-term harvesting (3-4 months).
