Summary: Microbial symbionts have significant impacts on hosts, with these impacts varying depending on the identity of the interacting partners and genetic variation at the strain level. Strain specificity can drive the molecular and ecological dynamics of host-symbiont associations, with factors falling into functional categories that contribute to association support or antagonistic interactions with other organisms. Understanding strain specificity is essential for comprehensively understanding host-symbiont dynamics, including in the human microbiome.

Summary: Two Legionella-like strains isolated from hot water distribution systems in 2012 were characterized phenotypically, biochemically, and genomically. The analysis based on various methods, including 16S rRNA gene sequences and comparative genome sequence-based analyses, confirmed that these strains represent a new species of the genus Legionella. The name Legionella maioricensis sp. nov. is proposed for this novel species.

Summary: Split-chamber zero resistance ammetry (SC-ZRA) was used to study microbiologically influenced corrosion by aerobic chemoorganotrophic microeukaryotes isolated from biodiesel storage tanks. The magnitude and direction of electric current were measured between two shorted carbon steel electrodes, which were deployed in separate chambers connected by a salt bridge (via a SC-ZRA assembly). This approach permitted rapid screening for the corrosive activity of these previously understudied microeukaryotes. During this study, two previously understudied microeukaryotes (Byssochlamys sp. SW2 and Yarrowia lipolytica) showed increased biomass, an increase in electrochemical signal (current), and a corresponding increase in corrosion rate (weight loss). However, other previously understudied microeukaryote (Wickerhammomyces sp. SE3) showed an increase in biomass without an increase in electrochemical signal and minimal corrosion rate, indicating that the SC-ZRA technique can screen for the corrosive activity of a microorganism, regardless of overall microbial activity. This technique could be used to quickly assess the corrosive potential for a range of previously understudied microorganisms.

Summary: In this study, Shewanella baltica strains isolated from the gut contents of wild Atlantic mackerel were analyzed using whole-genome sequencing. The study identified new variants of antibiotic resistance genes and found the presence of the mobile colistin resistance gene mcr-4.3 in a significant proportion of the strains. The analysis of the complete genome sequence of one strain further revealed the presence of multiple plasmids carrying different resistance genes. This study provides insights into the genetic diversity and mobility of antibiotic resistance genes in Shewanella spp., highlighting the importance of the marine environment in the emergence and dissemination of clinically important resistance genes.

Summary: This study investigates the burial and exhumation, biodegradation, and fluid circulation history of hydrocarbon reservoirs across the Colorado Plateau to understand the response of subsurface microbial life to changing surface conditions over geologic time. The findings show that microbial communities were likely sterilized during deep burial but later reintroduced through upward migration of hydrocarbons. Recent erosion brought reservoirs closer to the surface and facilitated microbial activity and hydrocarbon biodegradation. This study provides insights into the evolution of the hypo-Critical Zone and microbial interactions with rocks and fluids in crustal environments.

Summary: This study investigates the gut microbiota of wild great tits and finds that they are closely related to the host's state and the environment, especially for nestlings. The study also discovers that the gut microbiota is most sensitive during early development and is associated with environmental factors such as reproductive timing and hatching location. These findings are crucial for understanding the role of gut microbiota in the fitness of animals.

Summary: Research on exhaled breath has been hindered by the lack of standardized collection and analysis methods. The Respiration Collector for In Vitro Analysis (ReCIVA) sampling device has shown potential as a consistent and convenient method for breath collection, but its high costs have limited its widespread use. To reduce expenses and logistical burdens, the possibility of sterilizing and reusing disposable masks and filters has been hypothesized.

Summary: During the COVID-19 pandemic, wastewater surveillance has been widely used to monitor infection trends. A statewide program for routine wastewater monitoring of gastrointestinal pathogens was established in Oklahoma. The results showed that wastewater concentrations of Salmonella, Campylobacter, and norovirus exhibited similar seasonal patterns to reported human cases, and wastewater can serve as an early warning tool for increases in cases. The use of wastewater surveillance surpasses traditional methods and improves our understanding of gastrointestinal infections.
