Cecropin A and papiliocin are novel 37-residue cecropin-like antimicrobial peptides isolated from insect. We have confirmed that papiliocin possess high bacterial cell selectivity and has an α-helical structure from Lys(3) to Lys(21) and from Ala(25) to Val(35), linked by a hinge region. In this study, we demonstrated that both peptides showed high antimicrobial activities against multi-drug re...

A large number of people work with garbage collection, and exposure to microorganisms is considered an occupational health problem. However, knowledge on microbial exposure at species level is limited. The aim of the study was to achieve knowledge on waste collectors' exposure to airborne inhalable fungal and bacterial species during waste collection with focus on the transport of airborne micr...

BACKGROUND To monitor the richness in microbial inhabitants in the phyllosphere of apple trees cultivated under various cultural and environmental conditions, we developed an oligo-DNA macroarray for major pathogenic and non-pathogenic fungi and bacteria inhabiting the phyllosphere of apple trees. METHODS AND FINDINGS First, we isolated culturable fungi and bacteria from apple orchards by an ...

The effects of streptomycin sulfate, carbendazim, penicillin and nystatin on the inhibition fungi bacteria in blueberry explants were studied. results showed that addition sulfate or with different concentrations medium had a certain inhibitory killing effect explant contamination, while carbendazim contamination. When concentration reached 60units / mL, highest survival rate was 44.0%, bacteri...

The purpose of this study was to evaluate the minimum incubation time required to detect positive blood cultures from newborn infants with sepsis. Data were collected retrospectively on seventy-five positive blood cultures from newborn infants in the neonatal intensive care unit of Songklanagarind Hospital. The BacT/Alert Microbial Detection System had been used to culture the samples. Data wer...

Mycotoxins such as aflatoxins, fumonisins, trichothecenes, and ochratoxins are contaminants of many agronomic crops worldwide, and cause both economic losses and health effects. The potential of antagonistic microorganisms to be developed into biological control agents has been investigated in several crop systems, as alternatives to chemical fungicides for control of mycotoxigenic fungi. Labor...

1- (phthalazin-l'-yl-amino)-3-chloro-4-aryl-4h-(4o-rm ethyl)-2-azetidinones (3) were prepared by cycloaddition of-methyl substituted benzal hydrazinophthalazine (2) with chloro acetylchloride. the hydrazone (2) was synthesised by the condensation of 1- hydrazinophthalazine (1) with substituted aromatic aldehydes, ketones 7 acetophenones. 1- hydrazinophthalazine was prepared from the phthal...

We evaluated fungal and bacterial diversity in an established moss carpet on King George Island, Antarctica, affected by ‘fairy ring’ disease using metabarcoding. A total of 127 706 taxa were assigned. Ascomycota dominated the assemblages, followed Basidiomycota, Rozellomycota, Chytridiomycota, Mortierellomycota Monoblepharomycota. The community displayed high indices diversity, richness domina...

Bacteria and fungi are ubiquitous throughout the Earth's lower atmosphere where they often represent an important component of atmospheric aerosols with the potential to impact human health and atmospheric dynamics. However, the diversity, composition, and spatiotemporal dynamics of these airborne microbes remain poorly understood. We performed a comprehensive analysis of airborne microbes acro...
