salmonella enterica is recognized as one of the major food-borne pathogens with more than 2,500 serotypesworldwide. the present study addresses antimicrobial resistance of salmonella enterica serovar enteritidisisolates in iran. a collection of 151 salmonella spp. isolates collected from poultry were serotyped toidentify salmonella enteritidis. sixty-one salmonella enteritidis were subsequently...

the simultaneous cross-linking and antimicrobial finishing of bleached cotton and cationized cotton by 3-chloro2-hydroxypropyl trimethyl ammonium chloride (quat-188) with butane tetracarboxylic acid and nano titanium dioxide is studied and explored in the current study. butane tetracarboxylic acid (btca) as a cross-linking agent can be linked to the cotton cellulosic chains by covalent bonds an...

Antimicrobial peptides are short, positively charged, amphipathic peptides that possess a wide spectrum of antimicrobial activity and have an important role in the host's innate immunity. Lack of, or dysfunctions in, antimicrobial peptides have been correlated with infectious diseases, including periodontitis. Porphyromonas gingivalis, a gram-negative anaerobe and a major pathogen associated wi...

BACKGROUND In haematology/oncology units, the frequent and heavy use of broad-spectrum antimicrobials can lead to outbreaks of antimicrobial resistance. Increasing antimicrobial heterogeneity might be a useful strategy for preventing such resistance. METHODS A real-time antimicrobial use density (AUD) monitoring system (RAMS) was developed to precisely assess antimicrobial heterogeneity. This...

UNLABELLED BACKGROUND The design and applications of antimicrobial polymers is a growing field. Antimicrobial polymers can help to solve the problems associated with the use of conventional antimicrobial agents. Polymers with active functional groups can act as a carrier system for antimicrobial agents. In our study, we aim to prepare and develop some antimicrobial polymers for biomedical ap...

The need for novel antibiotics in an era where antimicrobial resistance is on the rise, and the number of new approved antimicrobial drugs reaching the market is declining, is evident. The underused potential of post-translationally modified peptides for clinical use makes this class of peptides interesting candidates. In this study, we made use of the vast amounts of available genomic data and...

Virulent group A streptococci have become a serious threat, with the emergence of the hypervirulent lineage M1T1. In this issue of Cell Host & Microbe, LaRock et al. (2015), uncover a role for the streptococcal M1 protein in neutralizing a key human antimicrobial peptide, cathelicidin.

OBJECTIVES To evaluate the development of pharmacist-led antimicrobial stewardship activities in English hospitals. METHODS Distribution of an electronic questionnaire to antimicrobial pharmacists or chief pharmacists in National Health Service hospitals in England. RESULTS Since a previous study, in 2005, overall numbers of specialist antimicrobial pharmacists, and their levels of experien...

We evaluated antimicrobial exposure, discharge diagnoses, or both to identify surgical site infections (SSI). This retrospective cohort study in 13 hospitals involved weighted, random samples of records from 8,739 coronary artery bypass graft (CABG) procedures, 7,399 cesarean deliveries, and 6,175 breast procedures. We compared routine surveillance to detection through inpatient antimicrobial e...

The aim of this study was to investigate the antimicrobial effect of chitooligosaccharides prepared by chitosanase from Pseudomonas CUY8. Antimicrobial activities of different degrees of deacetylation (DD) and polymerization (DP) of chitooligosaccharides against various species of bacteria and fungi were measured. The antimicrobial effects of chitooligosaccharides compared with chitosan and chi...
