Capturing the spatial structure of the benthic microbiome under an intensive aquaculture scenario in Chilean Patagonia

Identifying the microbial taxa that structure assemblages in response to local disturbances along the Chilean Patagonian coast is critical for understanding community reorganization and ecological risk in this vulnerable marine environment. Here, we examined benthic microbial interactions across sixteen sites spanning 42–44°S in the Inner Sea of Chiloé and adjacent fjord systems...

Postoperative wound microbiota in diabetic patients with perianal abscess: a 16s rRNA gene sequencing study

Perianal abscesses are common in colorectal surgery, requiring surgical drainage and wound care. Diabetic patients often experience delayed wound healing and increased infection risk due to systemic factors and altered microbiota.

Rapid and simple detection of HCV RNA: enhanced colorimetric RT-LAMP method using unmodified gold nanoparticles

Despite significant global efforts to control HCV infection, there has been no observed decline in the incidence of new infections or mortality. The asymptomatic and silently progressing nature of HCV infection delays the response to potential treatments. Hence, there is a need for rapid diagnostic techniques that enable the early detection and treatment of the disease before it...

Comparative analysis of biofilm detection methods and antibiotic resistance in catheter-associated uropathogens: a cross-sectional study from Syria

Catheter-associated urinary tract infections (CAUTIs) are a major healthcare challenge due to bacterial biofilm formation, which protects pathogens from antibiotics and host immune responses.

Early-life gut and oral microbiota development: a multi-niche study including mother-partner-infant triads

Early gastrointestinal microbiota establishment is crucial for host metabolism and immune development, with delivery mode and breastfeeding playing key roles. Vaginal delivery promotes colonization by maternal vaginal and gut microbes, while Caesarean section delivery leads to exposures of environmental and skin-derived microbiota. Although maternal contributions have been...

Seawater tides shaped mangrove sediment a bacterial community drastically distinct from supratidal land soil

The intertidal zone where mangroves inhabit is unique for both plants and microbes. The periodic seawater tides have allowed only a very small portion of woody plants to shift as mangroves. However, the understanding of how seawater tides shape bacterial community in mangrove sediment is not yet comprehensive. By comparing mangrove sediment in low-tidal zones to land soil in...

However, due to inadequate healthcare infrastructure in many resource-constrained...

Different phytoplankton distributions and assembly processes in marine water masses with contrasting nutrient conditions

Phytoplankton play a vital role in global primary production and carbon fixation in marine ecosystems. A comprehensive understanding of their distribution patterns and assembly mechanisms under different nutrient conditions is essential for phytoplankton ecology.

Bacterial and fungal compositions of the fecal microbiota were determined via 16S and ITS1 sequencing, respectively...

XGBoost-based urinary microbial signatures enable non-invasive diagnosis and prognosis for urothelial carcinoma

Urothelial carcinoma (UC) is the most common malignant tumor of the urinary system, characterized by high incidence and recurrence rates, posing a serious threat to human health. While previous studies have linked urinary microbiota alterations to bladder cancer, little is known about the broader spectrum of UC subtypes or their clinical implications. To address this gap, we...

Plant identity and environmental filtering are the key drivers of bacterial community structure in four desert plant species from the Sahara Desert in Morocco

Plant microbiome is a very wide research area playing a major role in agriculture and plant health.

(n = 20), Lycium intricatum Boiss. (n = 20), Nitraria retusa Asch. (n = 20) and...

Genome-wide screen uncovers novel host factors for L-A virus maintenance and a potential mutualistic-symbiosis relationship in yeast

Viruses are traditionally viewed as intracellular parasites that exploit host resources to propagate, often at the host’s expense. However, emerging evidence suggests more nuanced interactions, including potential mutualism. The L-A double-stranded RNA (dsRNA) virus, a non-lytic, cytoplasmic virus commonly found in Saccharomyces cerevisiae, presents an intriguing case, as it...

Evaluation of direct microbial identification by MALDI-TOF MS and antimicrobial susceptibility testing for early diagnosis of blood stream infections

Bloodstream infections (BSI) related mortality rates are increasing worldwide making it a medical emergency. This study has evaluated a new method for direct detection of pathogens and to perform direct antimicrobial susceptibility testing from the positive flagged blood culture. Early diagnosis and prompt treatment with appropriate antibiotics is the utmost need. A 30-minute...

Exploring the alteration of gut microbiota in the rats with steroid-induce osteonecrosis of the femoral head

Osteonecrosis of the femoral head usually occurred after glucocorticoid (GC) therapy. The gut microbiota was considered an indispensable part of maintaining human health, and the concept of the gut microbiota -bone axis was also proposed. In our study, we aimed to elucidate the link between steroid-induce osteonecrosis of the femoral head (SIONFH) and the gut microbiota; Methods...

Transport stress alters serum biochemistry and gut microbiota in Tibetan sheep (ovis aries): a 30-day recovery assessment

Transport stress poses a major challenge to the livestock industry. Studies have shown that transportation stress can cause depression, elevated body temperature and dysbiosis of intestinal microbiota in meat goats, and in severe cases, even lead to death of the animals, which in turn affects the economic efficiency of the farming industry. However, the changes in blood...
