background: acute bacterial meningitis is among serious infections of the central nervous system (cns). the early diagnosis and empiric antibiotic treatments have led to a reduction in morbidity and mortality rates. pcr and the enzymatic digestion of 16s rdna fragment following the pcr by universal primers led up fast and sensitive determination. the aims of the present study was to improve our...

Probiotics are increasingly used in aquaculture to control diseases and improve feed digestion and pond water quality; however, little is known about the antimicrobial resistance properties of such probiotic bacteria and to what extent they may contribute to the development of bacterial resistance in aquaculture ponds. Concerns have been raised that the declared information on probiotic product...

BACKGROUND Matrix-assisted laser desorption ionization time-of-flight (MALDI-TOF) mass spectrometry accurately identifies both selected bacteria and bacteria in select clinical situations. It has not been evaluated for routine use in the clinic. METHODS We prospectively analyzed routine MALDI-TOF mass spectrometry identification in parallel with conventional phenotypic identification of bacte...

Plant growth promoting rhizobacteria (PGPR) are known to influence plant growth by various direct or indirect mechanisms. Thirty–two strains were isolated from 15 soils sampled in central Iran, by using and comparing three different methods. The screening of soil samples by means of soil paste– plate method combined with isolation on mannitol agar proved to be the best strategy in terms of reli...
