While there have been numerous efforts to use genomic information to predict the optimal growth temperatures of bacteria and archaea, such models are often highly inaccurate when applied to taxa with lower optimal growth temperatures, inclu...
Temperature and pH growth preferences predict the pathogenicity and environmental distributions of nontuberculous mycobacteria [0.03%]
温度和pH生长偏好预测非结核分枝杆菌的致病性和环境分布特征

Matthew J Gebert et al.
The genus Mycobacterium is highly diverse, and in addition to Mycobacterium tuberculosis, it includes many other pathogenic and non-pathogenic taxa which are collectively referred to as the nontuberculous mycobacteria. Although a subset of ...
Host physiology-dependent lysis timing shapes bacteriophage competition under nutrient fluctuations [0.03%]
宿主生理依赖的裂解时机决定了营养波动下的噬菌体竞争

Anja K Ehrmann
When bacteriophages infect starved host bacteria, the restrictive host physiology may lead to prolonged latent periods and/or reduced burst sizes, compared to infection of a fast-growing bacterium. Using a mathematical model, we explore a s...
Influence of heterotrophs on phage infection of marine picocyanobacteria [0.03%]
异养生物对海洋微细蓝细菌噬菌体感染的影响
Allison Coe,Sierra M Parker,Nhi N Vo et al.
Allison Coe et al.
Picocyanobacteria Prochlorococcus and Synechococcus coexist with lytic phages and heterotrophic bacteria in the oceans. These phages are a significant cause of mortality, while heterotrophic bacteria can increase Prochlorococcus fitness by ...
Shifts in microbial communities driven by the replacement of seagrasses by benthic macroalgae may exacerbate heatwave effects in eutrophicated coastal lagoons [0.03%]
由海草被底栖大型藻类取代驱动的微生物群落变化可能会加剧富营养化海岸泻湖的热浪影响

Esther Rubio-Portillo et al.
Climate change is expected to increase both the frequency and intensity of marine heatwaves, prolonging periods of extreme sea surface temperatures. These events can disrupt stratification, reduce oxygen availability, and alter nutrient cyc...
Lactobacillus-fermented feed alters growth performance, fecal short-chain fatty acid contents, metagenomics, and metabolomics in growing pigs [0.03%]
乳酸菌发酵饲料对生长育肥猪生产性能、粪便短链脂肪酸含量、肠道微生物群和代谢组的影响

Hopanoids are a class of steroid-like lipids that fortify bacterial membranes. Derivatives of hopanoids known as "geo-hopanes" are abundant in sediments and are signatures of ancient bacteria, yet there are conflicting views on their use as...
β-Hydroxybutyrate precursor 1,3-butanediol modulates enteric pathogen susceptibility and Th17 responses via commensal bacteria [0.03%]
1,3-丁二醇通过共生细菌调节肠道病原菌易感性和Th17反应

Wenxuan Dong et al.
T helper 17 (Th17) cells are a critical T lymphocyte subset involved in mucosal immunity and host defense against enteric pathogens. Although ketogenic diets (KD) and the major ketone body β-hydroxybutyrate (BHB) reshape gut microbiota and...
A comprehensive study of intratumor bacteria in clear-cell renal cell carcinoma identifies Cutibacterium acnes as a protector via suppression of macrophage M2 polarization [0.03%]
全面研究透明细胞肾细胞癌的瘤内细菌发现 Cutibacterium acnes 通过抑制巨噬细胞 M2 极化发挥保护作用
Yuqing Li,Dengwei Zhang,Linyi Tan et al.
Yuqing Li et al.
Intratumor bacteria (ITB) have emerged as key modulators in various malignancies; however, their role in clear-cell renal cell carcinoma (ccRCC) remains unclear and elusive. In this study, we analyzed seven independent cohorts (comprising o...
Integrated multi-omics analysis reveals gut microbiota-associated placental metabolic and transcriptomic alterations in placenta previa [0.03%]
