background: the clinical diagnosis of meningitis is crucial, particularly in children. the early diagnosis and empiric an­tibi­otic treatments have led to a reduction in morbidity and mortality rates. pcr and the enzymatic digestion of 16srdna frag­ment which is produced by universal primers led up fast and sensitive determination. the purpose of this study was to investi­gate a rapid method fo...

Abstract Background Reinforcement corrosion and the concrete strength reduction are critical problems that resulted from crack creation in concrete. Very expensive hazardous technologies based on chemical materials have been provided for repairing cracks. Recently, repair using bio-catalysis precipitating bacteria has developed as a viable ecofriendly alternative technique. The main target of t...

The genus Collimonas consists of facultative, fungus-feeding (mycophagous) bacteria. To date, 3 species (C. fungivorans, C. pratensis and C. arenae) have been described and over 100 strains have been isolated from different habitats. Functional traits of Collimonas bacteria that are potentially involved in interactions with soil fungi mostly negatively (fungal inhibition e.g.), but also positiv...

Propionibacteria have mainly been found in dairy products and on the skin of humans animals. This genus classified as non-producing PHA but this study we show that Propionibacterium sp. can produce PHA. A member was isolated from soil. The isolate identified based its gram positive pleomorphic rods. Cells occur short chains, singly or pairs, V Y configurations. On mineral salt agar colonies are...

Three genes encoding membrane proteins of chrysanthemum yellows (CY) phytoplasma were cloned and sequenced: SecY, Amp and ArtI encoding the protein translocase subunit SecY, the antigenic membrane protein Amp and the arginine transporter ArtI, respectively. Alignments of CY-specific SecY sequences with the corresponding genes of other phytoplasmas confirmed the 16SrDNA-based classification, whi...

A total of 62 bacterial isolates were obtained from Gomsohang mud flat, Mohang mud flat, and Jeju Island, Republic of Korea. Among them, the isolate CNU114001 showed significant antagonistic activity against pathogenic fungi by dual culture method. The isolate CNU114001 was identified as Bacillus amyloliquefaciens by morphological observation and molecular data analysis, including 16SrDNA and g...

This study was aimed at collecting data on presence, dissemination and persistence of Pseudomonas in small-scale dairy farms. Six farms (located in Piedmont) were visited three times over 2014: 116 waters (wells and different faucets/pipes) and 117 environmental samples (milking equipments and drains) were collected. Enumeration of Pseudomonadaceae was performed, 3-5 colonies/samples were selec...

The objective of this study was to evaluate the quality of water purification system and identify the bacteria this system, predict bacterial adherence according to the hydrophobicity of these microorganisms and of the polypropylene distribution loop for purified water. The assessment of drinking water that supplies the purification system allowed good-quality physical, chemical, and microbiolo...

Sphingomonas wittichii, a close relative of the human pathogen Sphingomonas paucimobilis, is a microorganism of great interest to the bioremediation community for its ability of biodegradation to a large number of toxic polychlorinated dioxins. In the present study we investigated the presence of different virulence factors and genes in S. wittichii. We utilized phylogenetic, comparative genomi...
