Bacterial control promoted by bacteriophages (phages) is an attractive tool in the face of the antibiotic crisis triggered by the exacerbated use of these drugs. Despite the growing interest in using these viruses, some gaps still need answers, such as the protection and delivery of phages. Some limitation points involve the degradation of phage proteins by enzymes or inactivation in low-pH environments

Anthropogenic vs. natural habitats: Higher microbial biodiversity pays the trade-off of lower connectivity Microbiol. Res. (IF 6.7) Pub Date : 2024-02-21 Lingzi Mo, Augusto Zanella, Andrea Squartini, Giulia Ranzani, Cristian Bolzonella, Giuseppe Concheri, Massimo Pindo, Francesca Visentin, Guoliang Xu
Climate change and anthropogenic disturbances are known to influence soil biodiversity. The objectives of this study were to compare the community composition, species coexistence patterns, and ecological assembly processes of soil microbial communities in a paired setting featuring a natural and an anthropogenic ecosystem facing each other at identical climatic, pedological, and vegetational conditions

Cooperation of quorum sensing and central carbon metabolism in the pathogenesis of Gram-positive bacteria Microbiol. Res. (IF 6.7) Pub Date : 2024-02-21 Shuji Gao, Yuxin Wang, Shuo Yuan, Jing Zuo, Wenjie Jin, Yamin Shen, Daniel Grenier, Li Yi, Yang Wang
Quorum sensing (QS), an integral component of bacterial communication, is essential in coordinating the collective response of diverse bacterial pathogens. Central carbon metabolism (CCM), serving as the primary metabolic hub for substances such as sugars, lipids, and amino acids, plays a crucial role in the life cycle of bacteria. Pathogenic bacteria often utilize CCM to regulate population metabolism

SARS-CoV-2 Membrane protein regulates the function of Spike by inhibiting its plasma membrane localization and enzymatic activity of Furin Microbiol. Res. (IF 6.7) Pub Date : 2024-02-21 Qi Xiang, Jie Wu, Yuzheng Zhou, Linhao Li, Miao Tian, Guobao Li, Zheng Zhang, Yang Fu
The presence of a multibasic cleavage site in the Spike protein of SARS-CoV-2 makes it prone to be cleaved by Furin at the S1/S2 junction (aa. 685–686), which enhances the usage of TMPRSS2 to promote cell-cell fusion to form syncytia. Syncytia may contribute to pathology by facilitating viral dissemination, cytopathicity, immune evasion, and inflammation. However, the role of other SARS-CoV-2 encoding

Fecal microbiota transplantation ameliorates abdominal obesity through inhibiting microbiota-mediated intestinal barrier damage and inflammation in mice Microbiol. Res. (IF 6.7) Pub Date : 2024-02-20 Xiaoqiang Zhu, Lijun Zhao, Liang Lei, Yanhong Zhu, Jun Xu, Li Liu
Abdominal obesity (AO), characterized by the excessive abdominal fat accumulation, has emerged as a significant public health concern due to its metabolic complications and escalating prevalence worldwide, posing a more pronounced threat to human health than general obesity. While certain studies have indicated that intestinal flora contributed to diet-induced general obesity, the precise involvement

Sesame bacterial wilt significantly alters rhizosphere soil bacterial community structure, function, and metabolites in continuous cropping systems Microbiol. Res. (IF 6.7) Pub Date : 2024-02-17 Ruiqing Wang, Xinsheng Li, Fengjuan Lv, Junhai He, Rujie Lv, Lingen Wei
Bacterial wilt is the leading disease of sesame and alters the bacterial community composition, function, and metabolism of sesame rhizosphere soil. However, its pattern of change is unclear. Here, the purpose of this study was to investigate how these communities respond to three differing severities of bacterial wilt in mature continuously cropped sesame plants by metagenomic and metabolomic techniques

Phenogenetic profile and agronomic contribution of Azospirillum argentinense Az39T, a reference strain for the South American inoculant industry Microbiol. Res. (IF 6.7) Pub Date : 2024-02-15 G.A. Maroniche, M.L. Puente, J.E. García, E. Mongiardini, A. Coniglio, S. Nievas, M.M. Labarthe, F. Wisniewski-Dyé, E. Rodriguez Cáceres, M. Díaz-Zorita, F. Cassán
sp. is a plant growth-promoting rhizobacteria largely recognized for its potential to increase the yield of different important crops. In this work, we present a thorough genomic and phenotypic analysis of Az39 to provide new insights into the beneficial mechanisms of this microorganism. Phenotypic analyses revealed the following abilities: growth at 20–38 °C (optimum, 28 °C), pH 6.0–8.0 (optimum,
