Density feedback can occur via multiple mechanisms, including predator partitioning, and is often mediated by the physical environment. If species respond differently to the environment (e.g. susceptibility to predators changes under different conditions) then environmental fluctuations can provide the necessary separation of density feedback to promote coexistence. Additionally, directional change in environmental conditions (as with climate change) can yield overall shifts in community composition. We assess possible pathways that a fungal-like parasite (Saprolegnia spp.) could modify these effects in a community of Hydrobiosidae caddisflies. We exposed caddisfly egg masses from four species to four controlled temperature regimes in the laboratory and determined mortality from infection. Saprolegnia spp. infection in caddisfly egg masses is species specific, a signature for predator partitioning which can influence coexistence. The caddisfly species also differ in how temperature alters their infection rates, with dramatic shifts in relative infection rates depending on the duration and timing of periods of high temperature. Our findings suggest that Saprolegnia spp. infection could limit dominant species, shift community composition, and help stabilise coexistence under fluctuating temperatures. While we show key conditions of coexistence are met, quantifying the effect of these temperature-mediated infection rates would require measuring the extent to which they modify density-dependent feedback.</p>","PeriodicalId":11360,"journal":{"name":"Current Microbiology","volume":"83 6","pages":""},"PeriodicalIF":2.6,"publicationDate":"2026-05-07","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"147835115","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"生物学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Cassia alata, a plant recognized for its anti-inflammatory and antioxidant properties, has a potential natural treatment for coccidiosis. This study involved infection of mice with Eimeria papillata to assess the efficacy of C. alata leaf extract (CALE). A methanolic extract of C. alata was analyzed via gas chromatography-mass spectrometry (GC-MS) and tested its efficacy in 35 mice across seven groups, including controls and those treated with various dosages (125, 250, or 500 mg/kg BW) or amprolium. The study evaluated treatment success by quantifying fecal oocyst shedding, examining jejunal histology, measuring glutathione peroxidase (GPx) activity, and analyzing Caspase 3 protein and gene expression to assess host cell apoptosis. The results indicated that CALE had 14 phytochemical compounds. CALE led to significant morphometric reduction in the parasitic stages, compared to untreated infected mice. The 500 mg/kg BW dose of CALE was particularly effective in lowering fecal oocyst output. Additionally, GPx levels increased in mice treated with CALE and amprolium, while, caspase-3 immunoreactivity and gene expression were significantly reduced in CALE-treated mice.

Their non-viable nature eliminates risks such as microbial translocation, bacteremia, and sepsis, making them suitable for vulnerable populations including immunocompromised, critically ill, paediatric and elderly individuals. In addition, parabiotic exhibit improved thermal stability, extended shelf life, and easier incorporation into functional foods, nutraceuticals, and pharmaceutical formulations without cold-chain requirements. Mechanistically, parabiotics retain immunomodulatory, anti-inflammatory and have barrier-enhancing activities through interactions with host pattern recognition receptors, including Toll-like receptors, modulation of cytokine responses, and reinforcement of gut epithelial integrity. Preclinical and clinical studies support their therapeutic potential such as in case of heat-killed Lactobacillus acidophilus LB (L. acidophilus) has shown efficiency in managing acute paediatric diarrhoea, while heat-inactivated Lacticaseibacillus paracasei PS23 (Lcb. paracasei) has demonstrated improvements in muscle strength and inflammatory markers, including reduced C-reactive protein and interleukin-6 and increased interlukin-10 in elderly individuals. Similarly, inactivated Lactiplantibacillus plantarum (Lpb. plantarum) and Bifidobacterium strains have been associated with benefits in irritable bowel syndrome, atopic dermatitis, respiratory infections, visceral fat reduction, and antibiotic-associated dysbiosis. Synergistic combinations with prebiotics, postbiotics and related bioactives further enhance therapeutic outcomes in inflammatory, metabolic and infectious conditions. Advances in metagenomics, next-generation sequencing, proteomics, metabolomics, CRISPR-Cas systems, and synthetic biology are accelerating strain characterization, functional evaluation, and scalable production.
