Summary: This study investigates the use of biochar and acid stress-adapted PGPR inoculants to enhance soil fertility and improve maize growth in acidic sandy soil. The results showed that high doses of biochar treatment positively influenced the abundance of PGP bacteria, affecting soil bacterial communities and enhancing maize above-ground biomass. The study suggests that biochar can play a significant role in influencing soil nutrient cycles.

Summary: This study investigated the impact of pesticide formulations on soil fungal and bacterial communities in soil microcosms. The application of pesticides led to significant changes in the structure of these communities, particularly in the alpha-diversity of the fungal community. Certain genera showed changes in relative abundance that could serve as indicators of pesticide contamination. It is recommended to use these markers for large-scale assessment of the effects of pesticides on soil microbial communities.

Summary: This study assessed the effects of excessive application of K2SO4 on soil microbial community and functions in tobacco-planting soil. The results showed that high dosage of K2SO4 led to changes in soil quality indicators and significant impact on bacterial community composition. Compared to low dosage, high dosage of K2SO4 increased the relative abundance of certain nutrient-rich bacteria groups and potentially beneficial bacteria, but had adverse effects on certain bacterial groups related to carbon and nitrogen metabolism.

Summary: Microbial community structure and abundance in long-term abandoned cropland were influenced by monthly changes in moisture and temperature. The growing period exhibited higher bacterial abundance and diversity compared to the dormant period. The relative abundances of certain bacterial taxa varied seasonally, with Actinobacteria and Chloroflexi more abundant in the dormant period. Soil and air temperature positively correlated with microbial gene abundances.

Summary: Phagotrophic protist communities in long-term Cu-contaminated soils have important impacts on Cu-resistant bacterial populations. Certain communities, such as Cercozoa and Amoebozoa, increase the relative abundance of Cu-resistant bacteria, while the relative abundance of Ciliophora decreases. Phagotrophs positively influence the relative abundance of Cu-resistant and -sensitive ecological clusters, contributing to the abundance of the Cu resistance gene (copA).

Summary: Mosses are important colonizing organisms after glacier retreat and can accumulate nutrients through N-2 fixation. The development of moss-microbe interactions during succession is poorly understood, but relevant for understanding the impact of climate change and glacier retreat. In this study, we investigated the bacterial communities associated with two moss species and the underlying soil along a successional gradient in Iceland. We found that moss traits, such as carbon content and moisture, influenced the bacterial community structure, while moss N-2 fixation rates were determined by bacterial community composition.

Summary: The microbial abundance, diversity, and interactions in soil play a crucial role in ecosystem functions. Viruses can regulate microbial communities and processes, but the understanding of their relationships with environmental conditions is lacking. Soil properties like organic matter and nitrate content influence viral and bacterial abundance and reproduction strategies. Land management and physicochemical properties shape bacterial community composition, while viral community composition is closely related to cover plants. This study sheds light on how environmental factors influence virus-host interactions in soil ecosystems.

Summary: The study reported the epidemiology of carbapenem-resistant Klebsiella pneumoniae (CRKP) in a Malaysian teaching hospital, with bla(OXA-48) identified as the predominant carbapenemase gene. Infection or colonization by CRKP, especially NDM-producers, central venous catheter usage, and stoma were associated with higher in-hospital mortality. Early detection of CRKP isolates was crucial due to the potential high mortality rate associated with infection.

Summary: The prevalence of ESBL-producing Enterobacteriaceae has impacted the efficacy of beta-lactam antibiotics in treating UTIs. This study showed high rates of resistance to various beta-lactam antibiotics in ESBL-producing E. coli and K. pneumoniae isolated from UTIs, with carbapenems remaining the most effective treatment option. Flomoxef may serve as a potential alternative to carbapenems for treating UTIs caused by ESBL-producers in Malaysia.

Summary: In extreme desert environments, black septate endophytes (DSE) can benefit the relict plant Gymnocarpos przewalskii by assisting it to survive and maintain ecosystem stability. The colonization of DSE in the roots of G. przewalskii varies significantly with seasons and sites, with soil properties being a major factor affecting the composition of DSE. Additionally, the functional metabolite composition of DSE strains varies greatly with different drought levels and isolates, indicating the potential complementarity between different strains in helping hosts cope with drought stress.
