Abstract Purpose The application of fungicides is one the main strategies to prevent clubroot disease. Currently, numerous studies focus on changes in soil microbial community at different levels disease severity. However, effects and causative pathogen, Plasmodiophora brassicae , while preventing remain unclear. Methods In this study, we evaluated control efficacy three (fluazinam, metalaxyl-m...

Salinity is one of main abiotic stresses that causes adverse effects on plant growth and affects millions hectares around the world. Variability physical chemical properties soils has made field experiments notoriously difficult to evaluate. Plant tissue culture been used as a model system study physiological responses induced by salinity. The aim this work was evaluate tolerance salinity Handr...

The objective of this study was to use pyrosequencing of the 16S rRNA genes to describe the microbial diversity of bovine milk samples derived from clinically unaffected quarters across a range of somatic cell counts (SCC) values or from clinical mastitis, culture negative quarters. The obtained microbiota profiles were used to distinguish healthy, subclinically and clinically affected quarters...

The genetic diversity of siderophore-producing bacteria of tobacco rhizosphere was studied by amplified ribosomal DNA restriction analysis (ARDRA), 16S rRNA sequence homology and phylogenetics analysis methods. Studies demonstrated that 85% of the total 354 isolates produced siderophores in iron limited liquid medium. A total of 28 ARDRA patterns were identified among the 299 siderophore-produc...

In this study, the selection of bacteria on the basis of their migration via fungal hyphae in soil was investigated in microcosm experiments containing Lyophyllum sp. strain Karsten (DSM2979). One week following inoculation with a bacterial community obtained from soil, selection of a few specific bacterial types was noticed at 30 mm in the growth direction of Lyophyllum sp. strain Karsten in s...

Little is known about physiological factors that affect the sense of olfaction in dogs. The objectives of this study were to describe the canine nasal and oral microbiota in detection dogs. We sought to determine the bacterial composition of the nasal and oral microbiota of a diverse population of detection canines. Nasal and oral swabs were collected from healthy dogs (n = 81) from four locati...

River microbial communities play an important role in global nutrient cycles, and aggregated bacteria such as those in epilithic biofilms may be major contributors. In this study the bacterial diversity of River Taff epilithon in South Wales was investigated. A 16S ribosomal DNA (rDNA) clone library was constructed and analyzed by partial sequencing of 76 of 347 clones and hybridization with ta...

In the United States, commercial shell eggs are washed and graded before retail. Since passage of the Egg Products Inspection Act in 1971, processing guidelines have been set to ensure that external and internal characteristics are maintained. However, less is known about how commercial processing affects the safety of shell eggs. To identify enteric bacteria entering plants and persisting thro...
