AI Article Synopsis
- Previous studies focused on farming ants and their use of antifungal microbes, but this research investigates the symbiosis between carpenter ants and actinobacteria.
- * Antimycin A complex, produced by the isolated actinobacteria strain A10, was found to have significant antimicrobial and cytotoxic properties.
- * The study suggests that strain A10 may help protect carpenter ants from infections, although the exact nature of this relationship needs further exploration.*
Article Abstract
Antibiotics produced by symbiotic microorganisms were previously shown to be of crucial importance for ecological communities, including ants. Previous works on ant-actinobacteria symbiosis are mainly focused on farming ants, which use antifungal microbial secondary metabolites to control pathogens in their fungal gardens. In this work, we studied microorganisms associated with carpenter ant . Pronounced antifungal activity of isolated actinobacteria strain A10 was found to be facilitated by biosynthesis of the antimycin A complex, consisting of small hydrophobic depsipeptides with high antimicrobial and cytotoxic activity. The actinomycete strain A10 was identified as . We studied the antagonistic activity of strain A10 against several entomopathogenic microorganisms. The antifungal activity of this strain potentially indicates a defensive symbiosis with the host ant, producing antimycins to protect carpenter ants against infections. The nature of this ant-microbe association however remains to be established.

Background And Objectives: Plant growth-promoting rhizobacteria (PGPR) with a diverse set of traits can improve crop yield in agriculture. The current study aimed to evaluate the potential of multi-trait PGPR isolates as inoculants for maize growth.
Materials And Methods: In this study, 23 bacterial isolates were initially screened from maize plant rhizosphere.

Background: The hand, foot and mouth disease (HFMD) was caused by species of Enterovirus A and Enterovirus B in the Asian-Pacific region. Broad-spectrum monoclonal antibodies (mAb) that can bind multiple serotypes of enteroviruses have gradually become a research hotspot in the diagnosis, prevention and treatment of HFMD.
Methods: In this study, a mAb 1H4 was obtained using monoclonal antibody technology by immunizing purified virus particles of Coxsackievirus A5 (CV-A5).

The combined microbial-plant remediation has increasingly been used to remediate heavy metal-contaminated soil. Some microorganisms could enhance phytoremediation efficiency by solubilizing heavy metal and improve plant growth by producing phytohormones in the heavy metal contaminated soils. In the present study, a strong cesium (Cs)-tolerant fungal strain was identified from soil microorganisms contaminated with Cs, and the enrichment conditions for Cs were optimized.

Hexavalent chromium [Cr(VI)] is of public health significance due to its toxicity and carcinogenic effects. Kolaviron, a bio-flavonoid fraction from Garcinia kola seed, has been reported to possess gastroprotective and antioxidative properties. We hypothesize that Kolaviron-fortified diet will attenuate chromium (VI)-induced gut dysfunction and oxidative damage in Drosophila melanogaster.

Article Synopsis
- Coxsackievirus A10 (CVA10) has been increasingly linked to hand, foot, and mouth disease (HFMD) outbreaks worldwide, causing mild to severe health complications, including some fatalities; however, research on CVA10 is limited.
- A study conducted in Nanchang, China examined CVA10's epidemiological and genetic traits from 2015-2023, revealing that 3.04% of enterovirus-positive cases were attributed to CVA10, primarily affecting young children under 5 years old.
- Phylogenetic analysis indicated that CVA10 strains from Nanchang belong to genogroup C, with some strains showing mutations and connections to isolates from various countries, suggesting
