< em > In vitro < /em > evaluation of inhibitory effect of < em > Lactobacillus reuteri < /em > supernatant on the replication of herpes simplex virus type 1 and expression of < em > UL54, UL52 < /em > and < em > UL27 < /em > genes
CONCLUSION: The study findings indicated that the supernatant of L. reuteri has a potent anti-HSV-1 effect especially if it is incubated with the virus before inoculation into the cell. Its possible antiviral mechanism is to inhibit the virus by binding to it or changing the surface structure of the virus. Metabolites of L. reuteri can be considered as a novel inhibitor of HSV-1 infection.PMID:38682053 | PMC:PMC11055432 | DOI:10.18502/ijm.v16i1.14877 (Source: Iranian Journal of Microbiology)

Early detection of oral bacteria causing gum infections and dental caries in children
CONCLUSION: There were significant associations between dental/oral health and microbial community. Metabolism of the oral bacteria, including biofilm formation, can affect gums and develop dental plaques and hence dental caries, especially in children. Early diagnosis of dental caries in children via rapid, accurate molecular methods can increase the diagnostic capacity in clinical cases and therefore prevent periodontal infections in adulthood.PMID:38682052 | PMC:PMC11055450 | DOI:10.18502/ijm.v16i1.14870 (Source: Iranian Journal of Microbiology)

Hitching a Ride in the Phyllosphere: Surfactant Production of Pseudomonas spp. Causes Co-swarming of Pantoea eucalypti 299R
Microb Ecol. 2024 Apr 29;87(1):62. doi: 10.1007/s00248-024-02381-4.ABSTRACTHere, we demonstrate the beneficial effect of surfactant-producing pseudomonads on Pantoea eucalypti 299R. We conducted a series of experiments in environments of increasing complexity. P. eucalypti 299R (Pe299R), and Pseudomonas sp. FF1 (Pff1) or Pe299R and surfactant-production deficient Pseudomonas sp. FF1::ΔviscB (Pff1ΔviscB) were co-inoculated in broth, on swarming agar plates, and on plants. In broth, there were no differences in the growth dynamics of Pe299R when growing in the presence of Pff1 or Pff1ΔviscB. By contrast, on swarming agar ...

Inside the Host: Understanding the Evolutionary Trajectories of Intracellular Parasitism
Annu Rev Microbiol. 2024 Apr 29. doi: 10.1146/annurev-micro-041222-025305. Online ahead of print.ABSTRACTThis review explores the origins of intracellular parasitism, an intriguing facet of symbiosis, where one organism harms its host, potentially becoming deadly. We focus on three distantly related groups of single-celled eukaryotes, namely Kinetoplastea, Holomycota, and Apicomplexa, which contain multiple species-rich lineages of intracellular parasites. Using comparative analysis of morphological, physiological, and molecular features of kinetoplastids, microsporidians, and sporozoans, as well as their closest free-livi...

Appl Microbiol Biotechnol. 2024 Apr 29;108(1):312. doi: 10.1007/s00253-024-13155-w.ABSTRACTThe xylanolytic enzymes Clocl_1795 and Clocl_2746 from glycoside hydrolase (GH) family 30 are highly abundant in the hemicellulolytic system of Acetivibrio clariflavus (Hungateiclostridium, Clostridium clariflavum). Clocl_1795 has been shown to be a xylobiohydrolase AcXbh30A releasing xylobiose from the non-reducing end of xylan and xylooligosaccharides. In this work, biochemical characterization of Clocl_2746 is presented. The protein, designated AcXyn30B, shows low sequence similarity to other GH30 members and phylogenetic analysis...

Using multi-omics to explore the effect of Bacillus velezensis SAAS-63 on resisting nutrient stress in lettuce
This study explored the role of the plant growth-promoting rhizosphere bacteria (PGPR) strain Bacillus velezensis SAAS-63 in improving nutrient stress in lettuce. Compared with no inoculation, B. velezensis SAAS-63 inoculants exhibited significantly increased fresh weight, root length, and shoot height under nutrient deficiency, as well as improved antioxidant activities and proline contents. The exogenous addition of B. velezensis SAAS-63 also significantly increased the accumulation of macroelements and micronutrients in lettuce. To elucidate the resistance mechanisms induced by B. velezensis SAAS-63 under nutrient stres...

Biodegradation of polystyrene nanoplastics by Achromobacter xylosoxidans M9 offers a mealworm gut-derived solution for plastic pollution
This study investigated the degradation of nanoplastics by isolating bacteria from the gut microbiome of Tenebrio molitor larvae fed various plastic diets. Five bacterial strains capable of degrading polystyrene were identified, with Achromobacter xylosoxidans M9 showing significant nanoplastic degradation abilities. Within 6 days, this strain reduced nanoplastic particle size by 92.3%, as confirmed by SEM and TEM analyses, and altered the chemical composition of the nanoplastics, indicating a potential for enhanced bioremediation strategies. The strain also caused a 7% weight loss in polystyrene film over 30 days, demonst...
