Controlling sap-sucking insect pests with recombinant endophytes expressing plant lectin [PDF]

, 2010
We developed a novel pest management strategy, which uses endophytes to express anti-pest plant lectins. Fungal endophyte of Chaetomium globosum YY-11 with anti-fungi activities was isolated from rape seedlings, and bacterial endophytes of SJ-10 ...

Massive Increase, Spread, and Exchange of Extended Spectrum {beta}-Lactamase-Encoding Genes Among Intestinal Enterobacteriaceae in Hospitalized Children With Severe Acute Malnutrition in Niger. [PDF]

, 2011
Background. From the time of CTX-M emergence, extended-spectrum β-lactamase-producing enterobacteria (ESBL-E) have spread worldwide in community settings as well as in hospitals, particularly in developing countries.

From Membrane Composition to Antimicrobial Strategies: Experimental and Computational Approaches to AMP Design and Selectivity

Small, EarlyView.
Antimicrobial peptides (AMPs) are promising candidates for next‐generation antibiotics, acting through mechanisms such as membrane disruption and intracellular targeting. This review examines how variations in bacterial membrane composition critically influence AMP activity.

Distribution and Efficiency of Hydrocarbon-Oxidizing Bacteria in a Freshwater Reservoir [PDF]

, 1984
Hydrocarbon-oxidizing bacteria were identified from three stations on DeGray Reservoir, Arkansas. The organisms were primarily gram-negative rods representing 9 taxa and 37 biotypes Pseudomonas spp. were the most common isolates.

Vaginal infection by Enterobacter sakazakii [PDF]

Sexually Transmitted Infections, 2002
In August 2001, a 26 year old woman seen at our outpatient clinic in Budapest complained of vulvar pruritus and vaginal discharge in the preceding 2 weeks. The only risk factor she admitted was that she had bathed in the resort lake Balaton a few times a week before the onset of symptoms, when the water was unusually warm (26–28°C).

Vancomycin‐Modified DNA Origami Nanostructures for Targeting Bacterial Pathogens

Small Structures, EarlyView.
Applications of DNA origami nanostructures in pathogen detection and antimicrobial drug delivery require their efficient and robust binding to bacterial cells. Here, the cell wall‐binding glycopeptide antibiotic vancomycin is conjugated to selected staple strands and displayed in multivalent arrangements on the DNA origami surface to facilitate the ...

Characterization of Extracellular Chitinase from Bacterial Isolate 99 and Enterobacter sp. G-1 from Matsue City, Japan

Microbiology Indonesia, 2010
One hundred and twenty isolates of chitosanase producing bacteria were screened from water and soil from localies around Matsue city, Japan. In previous experiments, four isolates (isolates 96, 97, 99, and 100 strain ) were analyzed for their chitosanase

Arbuscular mycorrhizal fungus alters the phyllosphere microbial community and modifies plant defences against co‐attack of pea aphid and pathogen

Functional Ecology, EarlyView.
Read the free Plain Language Summary for this article on the Journal blog. Abstract Arbuscular mycorrhizal fungi (AMF), pathogens and insect pests usually colonize or infect the same plant. Besides, AMF changes plant defence enzymes and metabolites under multiple biotic stresses and alters the interrelationship between plant, pathogen and insect ...

Is the endophyte‐based plant protection against aphids mediated by changes in the insect microbiome?

Insect Science, EarlyView.
We showed that the fungal endophyte Epichloë strain AR37 increased the plant resistance against aphids via the production of indole diterpene alkaloids. The reduction in aphid performance was not associated with changes in abundance/composition/diversity of the insect's bacterial microbiota, but additional endophyte effects on this microbiota cannot be

Genetic Diversity and Functional Analysis of Sigma Factors in Resourced From Various Niche

Evolutionary Bioinformatics, 2018
Sigma factors are bacterial transcription factors that bind the core RNA polymerase and direct transcription initiation at a specific promoter site. These specialized sigma factors bind the promoters of genes appropriate to the environmental conditions ...
