Recurrent urinary tract infection with antibiotic-resistant in a patient with Crohn's disease: A case report.

Recurrent urinary tract infections with resistant strains of are a potential complication of the long-term use of immunosuppressive therapy in patients with Crohn's disease.

A Recombinant Snake Cathelicidin Derivative Peptide: Antibiofilm Properties and Expression in .

The emergence of antimicrobial resistance among pathogenic microorganisms has been led to an urgent need for antibiotic alternatives. Antimicrobial peptides (AMPs) have been introduced as promising therapeutic agents because of their remarkable potentials. A new modified cathelicidin-BF peptide (Cath-A) with 34 amino acid sequences, represents the potential antimicrobial effects against methicillin-resistant (MRSA) with slight hemolytic and cytotoxic activities on eukaryotic cells.

Carvacrol and human health: A comprehensive review.

Carvacrol (CV) is a phenolic monoterpenoid found in essential oils of oregano (Origanum vulgare), thyme (Thymus vulgaris), pepperwort (Lepidium flavum), wild bergamot (Citrus aurantium bergamia), and other plants. Carvacrol possesses a wide range of bioactivities putatively useful for clinical applications such antimicrobial, antioxidant, and anticancer activities. Carvacrol antimicrobial activity is higher than that of other volatile compounds present in essential oils due to the presence of the free hydroxyl group, hydrophobicity, and the phenol moiety.

The antimicrobial potential of a new derivative of cathelicidin from Bungarus fasciatus against methicillin-resistant Staphylococcus aureus.

Cathelicidins are a family of antimicrobial peptides which exhibit broad antimicrobial activities against antibiotic-resistant bacteria. Considering the progressive antibiotic resistance, cathelicidin is a candidate for use as an alternative approach to treat and overcome the challenge of antimicrobial resistance. Cathelicidin-BF (Cath-BF) is a short antimicrobial peptide, which was originally extracted from the venom of Bungarus fasciatus.

Emergence of blaCTX-M-15, blaTEM-169 and blaPER-1 extended-spectrum β-lactamase genes among different Salmonella enterica serovars from human faecal samples.

Background: Broad-spectrum β-lactams are used for empirical therapy of severe infections with non-typhoid Salmonella serotypes; however, activities of these drugs against the strains producing different β-lactamase is not so clear. This study investigated the prevalence of β-lactamase genes among isolates of S. enterica serovars from human faecal samples and determined their diversity in activity against different β-lactams.

Antimicrobial-resistant Shigella infections from Iran: an overlooked problem?

Objectives: In this study, we wanted to assess the level of antimicrobial resistance, the presence of genes encoding resistance to cephalosporins and plasmid-mediated quinolone resistance (PMQR), and genetic relatedness among Shigella isolates obtained from Iranian patients.

Methods: A total of 44 Shigella isolates were collected from Iranian patients admitted to Milad Hospital, Tehran, Iran, during 2008-10. Of these, 37 were serotyped and characterized by MIC determination.

Antimicrobial resistance in Salmonella spp. recovered from patients admitted to six different hospitals in Tehran, Iran from 2007 to 2008.

The objective of this study was to assess the genotypic diversity associated with antimicrobial susceptibility of Salmonella serovars isolated from patients arriving with diarrhoea to six hospitals of Tehran, Iran. During 2007-2008, a cross-sectional convenience study was performed. Stool samples were screened for the presence of Salmonella, serotyped, tested for antimicrobial susceptibility using disk diffusion and examined for the presence of relevant resistance genes and integrons by PCR.

Phylogenetic relationship of Salmonella enterica strains in Tehran, Iran, using 16S rRNA and gyrB gene sequences.

Introduction: We assessed whether 16S rDNA and gyrB gene sequences, alone or combined, were suitable for determining the phylogenetic relationship among Salmonella enterica strains isolated from Tehran, Iran. Patients over five years of age enrolled in an acute diarrheal surveillance project in Tehran province between May 2004 and October 2006 were selected as our study group.

Methodology: 16S ribosomal DNA (rDNA) and gyrB genes from 40 Salmonella isolates obtained from patients with acute diarrhea were sequenced and the data was used to generate phylogenetic trees that facilitated isolate comparison.

Detection of novel gyrA mutations in nalidixic acid-resistant isolates of Salmonella enterica from patients with diarrhoea.

The aim of the current study was to detect mutations in the gyrA gene of quinolone-resistant Salmonella spp. isolates recovered in Tehran, Iran. Between April 2008 and September 2009, 174 Salmonella spp.

Emergence of extended-spectrum beta-lactamases in clinical isolates of Salmonella enterica in Tehran, Iran.

The purpose of the current study was to investigate the presence and molecular type(s) of extended-spectrum beta-lactamases (ESBLs) in Salmonella spp. isolates obtained from patients with diarrhea in hospitals of Tehran, Iran. Over a period of 17 months, 129 Salmonella spp.
