conclusion a comparison of these data with those of other countries showed that there was considerable geographic variation in bacterial patterns of sensitivity and resistance properties. therefore, the selection of antibiotics for empiric therapy especially in children with terminal renal failure on continuous ambulatory peritoneal dialysis (capd) treatment should be based on the knowledge of ...

Background Cystic fibrosis (CF) is an autosomal-recessive, life-shortening disease caused by a defect in the CF transmembrane conductance regulator (CFTR) gene encoding the CFTR chloride channel protein. The physiopathologic changes in the lungs of these patients triggers the development of pulmonary infections caused by various microorganisms, most commonly by Pseudomonas aeruginosa, and 80 % ...

Background & objectives: Safety control of traditional raw milk cheese such as Pot cheese is of special importance. Although enterococci can play beneficial probiotic or technological properties in cheese and their use in food is the subject of debate due to evidence of pathogenicity and antibiotic resistance. Method: In the present study, after isolation and morphological and biochemical iden...

conclusions the results showed that e. coli isolated from patients with uti had eight virulence factors with high frequencies. moreover, these results alleged a direct connection between virulence factors and antimicrobial resistance in e. coli. results the frequency of virulence factors papc, afa, sfa/foc, fimh, hly, neuc, ibea, and iucc were 53.3%, 51.7%, 53.3%, 56.7%, 23.3%, 31.7%, 20%, and ...

The fitness effects of a mutation can depend, sometimes dramatically, on genetic background; this phenomenon is often referred to as "epistasis." Epistasis can have important practical consequences in the context of antimicrobial resistance (AMR). For example, genetic background plays an important role in determining the costs of resistance, and hence in whether resistance will persist in the a...

A bacterial isolate from soil, designated as TB-2125 had a unique pattern of multiple resistance to aminoglycoside antibiotics (AG) and produced new nucleoside antibiotics. Taxonomic properties of this strain fell into those of Bacillus circulans, providing unique characteristics such as strict susceptibility to acidic pH, motility of colony as well as multiple AG-resistance. Two new antibiotic...
