Summary: In desert-like areas of eastern Utah, bacterial community composition is significantly influenced by pH and organic matter concentration, with Proteobacteria and Gemmatimonadetes being the predominant phyla in high-altitude desert soils. The relative abundance of these phyla is correlated with soil pH and organic matter concentration, suggesting their importance in shaping bacterial community structure in these environments.

Summary: The blowfly species Lucilia sericata and Lucilia cuprina play roles as agricultural pests, in forensics, and in medicine. While L. sericata larvae are used in maggot debridement therapy, L. cuprina larvae are major initiators of sheep myiasis in certain regions. Bacterial DNA extraction and sequencing showed that digestive tracts and female salivary glands carried the most bacteria in both species, with genera Pseudomonas and Corynebacterium being highly represented. Further research could focus on key organs like spermathecae and salivary glands to understand the role of bacteria in the blowfly life cycle.

Summary: This study examined the effects of Cry1B protein on the growth and development of non-target natural enemies. The results showed that Cry1B protein had no significant impact on the health indicators of P. astrigera, but it did reduce the number of symbiotic bacteria species and species diversity. The effects of Cry1B protein on symbiotic bacteria varied by growth and development stage and sex.

Summary: This study used 16S rRNA gene pyrosequencing to identify bacterial communities in wastewater and investigate the evolution of bacterial communities in the Anammox process. Four lab-scale Anammox reactors inoculated with different types of wastewater treatment sludge were operated under identical conditions for over 400 days. The study found that the presence of the Nitrospira genus and symbiotic association with other functional groups can lead to successful nitrogen removal in the Anammox process.

Summary: The gut microenvironment of houseflies plays a crucial role in their development and immune response. This study isolates and analyzes different bacterial strains from housefly larvae, and finds that the oral administration of various bacteria has differential effects on larval development and immunity. Beneficial bacteria can be used as probiotic additives for larvae feeding, while harmful bacteria could be targeted for pest control. Additionally, the study provides insights into the immune response of houseflies to external microorganism stimulation.

Summary: Soil cadmium (Cd) pollution poses a significant threat to flora and fauna due to its non-degradable and transferable nature. This study investigated the impact of endogenous Cd-polluted mulberry leaves on the gut microbiota of silkworms (Bombyx mori). The results revealed that Cd exposure caused significant changes in the gut bacterial composition of the silkworms, but had negligible effects on the phyllosphere bacteria of mulberry leaves. The findings suggest that the perturbations in the gut microbiota of B. mori are driven by Cd content rather than phyllosphere bacteria.

Summary: Obesity is causing many concomitant diseases, and new strategies for treatment and prevention are being developed using probiotics to modulate the gut microbiota. A study found an increase in Actinobacteriota and a decrease in Bacteroidota in obese patients taking lactic acid bacteria. Beneficial groups like Bifidobacterium and Lactococcus increased, while harmful groups like Faecalibacterium and Clostridium decreased. Modulating the gut microbiota with lactic acid bacteria may be a way to treat obesity.

Summary: Earthworms play an important role in soil ecosystem functioning and are used as indicators of ecosystem health. This study investigates the interactions between earthworms and soil microorganisms by comparing soil with and without earthworms in microcosms. The results show that earthworms increase microbial activity, decrease species richness, and shape soil prokaryotes community structure. Certain bacterial phyla were enriched, while the relative abundance of the archaeal phylum Thaumarchaeota decreased in the presence of earthworms. The study highlights the influence of earthworms on soil microbial communities and their activity, suggesting the need to incorporate earthworm-prokaryote interactions in future soil microbiome studies.

Summary: The study identified the bacterial communities associated with the plasmodia of six myxomycetes species and found that while the bacterial composition varied among species, there was a high similarity in the functional composition of the bacterial communities. The enrichment for gram-negative and aerobic bacteria in plasmodia suggests that myxomycetes may selectively recruit certain bacteria from the environment.

Summary: This study evaluated the effects of acute exposure to 75-nm polystyrene nanoplastics on the immune responses, antioxidant defenses, and gut microbiota of Eriocheir sinensis. After 48 hours of exposure, nanoplastics were found in the gills, hepatopancreas, and gut, but not in the gut after 7 days of recovery. Exposure to nanoplastics altered the expression of immune-related genes and enzyme activities, as well as the diversity of gut microbiota. The hepatopancreas of E. sinensis could not fully recover within a 7-day recovery period.

Summary: Nitrogen compounds, especially ammonia, are produced in aquaculture systems. In this study, two strains of Pseudomonas bacteria isolated from shrimp pond water were analyzed to understand their genetic characteristics and metabolic pathways related to ammonia reduction. The analysis showed that these strains belong to Pseudomonas putida and share a common ancestor with 33 genomes. Three genes, carbamate kinase (arcC), glutamine synthetase (Glul), and aminomethyltransferase (amt), were found to be involved in three metabolic pathways, potentially playing important roles in ammonia reduction and bacterial growth via ammonia assimilation.

Summary: This study investigated the growth kinetics of foodborne pathogen B. cereus during the commercial production of liquid egg yolk using PLA(2) treatment. The results showed that B. cytotoxicus NVH391-98 can grow prolifically at 50 degrees C, with estimated minimum, optimum, and maximum temperatures of 16.7-18.5, 47.8-48.1, and 52.1-52.4 degrees C, respectively. The dynamic model was validated with isothermal curves and it was found that holding the temperature below 15 degrees C or above 55 degrees C can effectively prevent the growth of B. cytotoxicus in egg yolk.

Summary: The infection mechanisms of Arcobacter are still uncertain. This study found that Arcobacter isolates from food and water sources were able to adhere and invade Caco-2 cells, and carried at least two virulence markers. A. butzleri showed higher virulent activity compared to A. cryaerophilus, while A. lanthieri, A. skirrowii, and A. vitoriensis exhibited even higher adhesion and invasion values. Sewage isolates were more adherent and invasive, and had a higher gene content. The association between cadF and hecA with high adhesion capability was identified for the first time.

Summary: Interactions between bacterial species in the formation of dual-species biofilms in the food industry are affected by environmental stresses, such as temperature and pH. This study found that the combination of cold and acid stresses significantly increased biofilm formation, and different temperatures resulted in variations in the presence of specific bacterial species and the secretion of extracellular substances. The findings provide valuable insights for addressing mixed biofilms in food processing under diverse stressful conditions.

Summary: This research investigates the role of flagella-related genes in the adhesion of E. coli O157:H7 and the effects of certain cations on bacterial adhesion and motility. The results demonstrate that flagellar-mediated motility is critical in the early stage of adhesion, and the presence of Fe2+, Ca2+, and Mn2+ affects the adhesion and motility of wildtype strains but not flagellar function-impaired strains. These findings provide new insights into the mechanisms of bacterial adhesion and have implications for the development of anti-adhesion agents.
