Summary: Fisheries research has been a source of excitement and discovery for me, rather than just a job. From finding new fish species to understanding their longevity and the impact of atmospheric chemicals on their survival, every day has been full of surprises. There are now better opportunities to understand the dynamics of fish populations, especially as climate change threatens their habitats. It is crucial to have young, team-oriented individuals who can pursue these new opportunities.

Summary: This study optimized a workflow for detecting metabolites in feces using bacterial biosensors. By removing host microbes through simple centrifugation and filtration steps, a physiological media retaining important characteristics of human feces was successfully prepared for metabolite detection. Bacterial biosensors showed high sensitivity to fecal matrices, but encapsulating the bacteria in hydrogel helped reduce the inhibitory effect. This work lays the foundation for monitoring fecal metabolites using bacterial biosensors and allows for rapid pre-prototyping of engineered bacteria for gut-related applications.

Summary: This study aimed to detect paratuberculosis-positive herds using a combination of random sampling and sample pooling, finding that pools of size 10 can be used without a significant decrease in detection probability compared to pools of size 5, and that the detection probability of pooled samples can be increased by the positive association between bacterial density and detection probability.

Summary: The study evaluated the stability of fecal microbial community over 18 months and compared six different storage conditions. Results showed that using DNA/RNA Shield-fecal collection tubes produced the best preservation of taxonomic composition after 18 months. Additionally, there were minimal differences in alpha and beta diversity metrics across different storage conditions.

Summary: This study demonstrates that storage conditions and buffers strongly affect the infectivity and genome recovery rate of bacteriophages. The choice of buffer has a larger impact than storage temperature and time on the quality of viral sequences. Recommendations are made for optimal storage of fecal virome samples.

Summary: The biology of burrowing crayfishes is not well understood due to their underground habitat. We conducted a 24-hour video recording survey on the Little Brown Mudbug and discovered that they exhibit sit-and-wait predatory behavior and consume both animals and plants. This study provides new insights into the foraging behavior and trophic role of burrowing crayfishes.

Summary: In this study, the impact of two sample preservation methods, freezing at minus 80 degrees C and freeze-drying, on the microbiome of mole-rat fecal samples was compared. The results showed minimal differences in microbiome composition between the two preservation methods, suggesting that freeze-drying samples can be a cost-effective method for transportation and storage of microbiome samples.

Summary: The study compares the microbiological quality of raw meat-based diets (RMBDs) and extruded diets, and finds that RMBDs may increase the risk of zoonotic pathogen infection. The survey also reveals dog owners' lack of awareness or underestimation of the risks associated with RMBDs.

Summary: This study analyzed the detection rates of SARS-CoV-2 in COVID-19 patients' fecal samples using four real-time RT-PCR kits and two pretreatment methods. The results showed that the Trizol pretreatment group had a slightly higher detection rate, and the DAAN kit had the highest NAT positive rate, which was related to the severity of the disease.

Summary: In this study, the presence of E. bieneusi in cattle in Austria was detected using PCR. It is the first report of E. bieneusi in cattle in Austria. The results showed a higher prevalence of E. bieneusi in calves compared to adult cows, with some cases showing co-infection with multiple genotypes. The age of the calves, history of antimicrobial treatment, and co-infection with other parasites were all associated with E. bieneusi infection.

Summary: This study compared the levels of different ADAMTS and TIMP-3 in healthy pulp and symptomatic irreversible pulpitis. The results showed that ADAMTS-1 and -9 and TIMP-3 levels were higher in pulpitis, while ADAMTS-4 was not related to pulpitis.

Summary: It is generally believed that microbial digestion plays a minimal role in reducing digesta particle size in herbivores, with faecal particle size reflecting chewing efficiency and diet variations. Overall, there is a decrease in mean particle size along the gastrointestinal tract, especially in hindgut fermenters. The study suggests that within a species, mean particle size cannot be used as an indicator of diet quality or digestibility, and there may be more significant reductions in smaller terrestrial herbivores compared to larger species.
