Summary: In this study, a diagnostic platform based on the viral glycoprotein B (gB) for Chelonid herpesvirus 5 (ChHV5) infection was successfully developed. The serological test and immunohistochemical analysis using the developed platform showed that seropositive sea turtles were significantly associated with fibropapillomatosis (FP), and ChHV5 displayed higher activity in the ballooning degeneration area of FP lesions.

Summary: The study found no cases of fibropapillomatosis or active viral infection in turtles examined in Grenada, but 34.6% of green turtles were previously exposed to the virus. The first confirmed case of fibropapillomatosis in Grenada occurred in 2020, indicating rare active viral infection but relatively high viral exposure in green sea turtles in the region.

Summary: A study on Neisseria gonorrhoeae multilocus sequence type (ST) 1901 found that this lineage is commonly associated with treatment failure, particularly due to alleles linked to reduced susceptibility to extended-spectrum cephalosporins (ESCs). The genetic diversity of ST-1901 was classified into minor and major clades, both originating in East Asia and dispersing globally in waves, with one clade acquiring a gene that significantly reduces susceptibility to ESCs. Despite declining effective population sizes, the lineage has become a reservoir for clones resistant to ceftriaxone, a key drug for gonorrhea treatment.

Summary: The study found that microorganisms exhibit continental-scale endemism, but this endemism generally occurs at extremely small phylogenetic scales, with most species and closely related strains being globally distributed. Human activities have a significant impact on microbial dispersal, with human-associated lineages dispersing faster than other terrestrial lineages.

Summary: A study found that green turtles in the waters around Mabul Island are infected with a virus called ChHV5, with a 42.9% increase in prevalence compared to previous sampling in 2015-2016. In addition, hawksbill and olive ridley turtles were also found to be infected with ChHV5 for the first time. The increased prevalence of the virus should be considered a potential threat, and efforts should be made to prevent its spread among the turtles in the area.

Summary: This study used Bayesian phylogeography to investigate the transmission patterns and evolutionary characteristics of equine influenza virus (EIV). The findings revealed that North America is the major source of globally dominant EIV variants, which spread to other regions. In the United States, EIV strains primarily spread from the southern and midwestern regions to other areas. The study also identified an average of three nucleotide substitutions per year in the HA gene of EIV H3N8, driven by heterogeneous local positive selection.

Summary: In this study, the proportion of Epstein-Barr virus (EBV)-positive gastric cancer was systematically explored. The prevalence of EBV in gastric tumors was 7.5%, higher in men, diffuse type, and proximal region. Developing an effective EBV vaccine could potentially prevent 81,000 EBV-associated gastric cancer cases annually.

Summary: This study analyzed the origin and transmission of Porcine Delta Coronavirus (PDCoV) and identified significant mutation sites. The research suggests that PDCoV might originate in Asia and has the potential for cross-species transmission. The findings are significant for understanding the zoonotic potential of PDCoV and enhancing biosecurity precautions.

Summary: The Neisseria gonorrhoeae ST-9363 core-genogroup strain with reduced azithromycin susceptibility has shown clonal expansion globally. By analyzing the genomes of this strain, researchers have discovered three lineages and multiple clades within them. The strain is believed to have originated from Asia but the modern lineages emerged from Europe in the late 20th century. The European lineage spread to North America and Oceania in the mid-2000s with multiple reintroductions into Europe. The study highlights the importance of monitoring this strain as it could acquire additional resistance markers.

Summary: Due to the frequent international and intercontinental transmission of multidrug-resistant bacteria, it is imperative to understand the epidemiology, phylogeography, and population structure of carbapenem-resistant Salmonella enterica (CRSE) across the globe. Our findings on the worldwide spread and transmission dynamics of this emerging bacterium has increased the knowledge of its global epidemics. Continued epidemiological surveillance is necessary to prevent global outbreak of multidrug-resistant Salmonella infections.

Summary: The reproductive success of sea turtles on Maio Island, Cabo Verde, is influenced by the environmental and biological conditions of the nesting beach. The study found that ghost crab predation is a major source of mortality for loggerhead nests on the island. The impact of ghost crab predation varies between different sand colorations, with darker sand beaches experiencing higher clutch mortality due to predation.

Summary: This study investigates the connectivity within the West African regional MPA network using satellite tracking of green turtles. The results show that the population connects five MPAs, but some important foraging and migration areas are currently unprotected. These findings have implications for expanding or establishing MPAs within the regional network to meet conservation targets.

Summary: Population connectivity plays a significant role in the distribution of genetic diversity and divergence along a species range. However, understanding the inter-population dispersal processes in sessile marine species with no planktonic life stages is still limited. This study examines the genetic differentiation of the seagrass species Halodule wrightii along the western coast of Africa and investigates the hypothesis of predominant transportation of rafting seagrass by ocean currents or biotic vectors of dispersal. The results reveal low divergence among most populations, supporting the hypothesis of biotically mediated seed transport and suggesting independent sources of colonization.

Summary: This recent publication evaluates microbial genome sequences from DNA isolated from ancient bones and compares them with those found in the surrounding soil. It discusses the importance of considering environmental contamination in paleomicrobiological analyses and highlights the fact that some samples do not contain their own microbiota, resulting in microbial sequences only from the surrounding environment.

Summary: Nest site selection is crucial for hatching success and population viability in sea turtles. A study on loggerhead turtles in Cabo Verde found that females preferentially nested in the middle of the beach, avoiding the tideline and vegetation line. It was suggested that relocation of doomed clutches should be considered for conservation, assuming nest choice is a heritable trait, and beach vegetation should be preserved, particularly in areas with human development.

Summary: In September 2021, Bagaza virus (BAGV), a member of the Ntaya group from the Flavivirus genus, was detected for the first time in Portugal. The genomic characterization of the BAGV strain from Portugal showed a close relationship with BAGV strains previously detected in Spain, suggesting a common ancestor that arrived in the Iberia Peninsula in the late 1990s to early 2000s. This study also supported the classification of BAGV and Israel turkey meningoencephalitis virus (ITV) as the same viral species.

Summary: Satellite tracking is an important tool for studying sea turtles in the wild, but there is still limited knowledge about male sea turtles. By tracking male green turtles during the breeding season, researchers found differences in migration distances between males and females, with male foraging areas overlapping with those of females. These findings provide important insights into the reproductive roles and movement ecology of sea turtles.
