The aim of this study was to assess the prevalence of ESBL-producing E. coli in agricultural fields of Gorgan district, Golestan province. Soil samples were collected from 20 agricultural fields, half of them treated with chemical fertilizers and the rest with bovine manure. Two samples, from surface and a depth of 15cm, were taken. After enrichment and culture onto MacConkey agar, Pink colored...

introduction: acinetobacter baumannii, a known causative agent of nosocomial infections, is one of the highly antibiotic-resistant gram-negative bacilli. carbapenem-resistant acinetobacter isolates are increasingly reported worldwide. carbapenems such as imipenem and meropenem are efficient antimicrobial agents commonly used for the treatment of infections caused by multi- resistant a. baumanni...

BACKGROUND We have studied the rate of emergence of antibiotic-resistant Streptococcus pneumoniae (S. pneumoniae) and Haemophilus influenzae (H. influenzae) and the subsequent antibiotic use in host patients of those isolates at the Department of Pediatrics, Soma General Hospital, Fukushima. Moreover, we carried out several studies investigating the risks and benefits of antibiotic-free treatme...

Biocides are used without restriction for several purposes. As a consequence, large amounts of biocides are released without any control in the environment, a situation that can challenge the microbial population dynamics, including selection of antibiotic resistant bacteria. Previous work has shown that triclosan selects Stenotrophomonas maltophilia antibiotic resistant mutants overexpressing ...

The increasing threat of pathogen resistance to antibiotics requires the development of novel antimicrobial strategies. Here we present a proof of concept for a genetic strategy that aims to sensitize bacteria to antibiotics and selectively kill antibiotic-resistant bacteria. We use temperate phages to deliver a functional clustered regularly interspaced short palindromic repeats (CRISPR)-CRISP...

The rapid and ongoing spread of antibiotic resistance poses a serious threat to global public health. The indiscriminant use of antibiotics in agriculture and human medicine along with increasingly connected societies has fueled the distribution of antibiotic-resistant bacteria. These factors together have led to rising numbers of infections caused by multidrug-resistant and pan-resistant bacte...

conclusions this blis with broad-spectrum activity may be a potential agent for the treatment or control of drug-resistant strains of p. aeruginosa infection. results among the 96 isolates of p. aeruginosa, 2 (2.1%), 94 (97.9%), and 63 (65.6%) were non-mdr, mdr, and xdr, respectively, and 1 (1.1%) was pdr. the most effective antibiotics against these isolates were polymyxins and fosfomycin. a b...

background pseudomonas aeruginosa is an opportunistic pathogen mostly affecting hospitalized and immunodeficient patients. considering the extent of attention paid to the issue of antibiotic resistance and the origin of such resistance and the growing number of treatment failures in patients with burn injury, it seems that investigating the degree of ampc gene expression could be beneficial for...
