Research on Piscirickettsia salmonis, a critical pathogen affecting salmon aquaculture, has been hampered by inadequate host models to study the infection process in vivo. Here, we highlight zebrafish as a surrogate host model for in-depth analysis of P. salmonis infection by using fluorescent dyes and protein markers to visualize host-pathogen interactions.

Article Synopsis
  • The extreme and remote high-latitude regions of Antarctica, particularly near the South Pole, have shown the presence of microbial life, with limited knowledge about their genetic traits and capabilities.
  • Research focused on soils from Union Glacier revealed a less diverse bacterial community compared to other regions, with predominant phyla being Actinomycetota and Pseudomonadota, and identified over 80 species-level genomes, including a novel ammonia-oxidizing archaeon.
  • The study discovered multiple antibiotic-resistant bacteria with potential pathogenic qualities, which produced various virulence factors, highlighting concerns about microbial resistance emerging from these isolated environments.

Parent-child interaction therapy (PCIT) is a highly efficacious, evidence-based treatment for children with disruptive behaviors and their families. PCIT is a dyadic therapy designed to improve parent-child relationships and decrease children's behavioral problems. PCIT research specific to Black families is currently sparse.

In 2015, the largest recorded harmful algal bloom (HAB) occurred in the Northeast Pacific, causing nearly 100 million dollars in damages to fisheries and killing many protected marine mammals. Dominated by the toxic diatom , this bloom produced high levels of the neurotoxin domoic acid (DA). Through molecular and transcriptional characterization of 52 near-weekly phytoplankton net-tow samples collected at a bloom hotspot in Monterey Bay, California, we identified active transcription of known DA biosynthesis () genes from the three identified toxigenic species, including as the primary origin of toxicity.
