Background: Treatment of chronic sinusitis is complicated due to increase of antibiotic-resistant bacteria. The aim of this study was to determine the multidrug resistance (MDR) pattern of the bacteria causing chronic sinusitis in north of Iran. Methods: This cross-sectional study was carried out on patients with chronic sinusitis. Bacterial susceptibility to antimicrobial agents was determi...

background : cockroaches mechanically spread pathogenic agents, however, little is known about their gut microbiota. identification of midgut microbial community helps targeting novel biological control strategies such as paratransgenesis. here the bacterial microbiota of periplaneta americana midgut, were identified and evaluated for finding proper paratransgenesis candidate. methods : midgut ...

background: strepotococcosis caused by streptococcus iniae is one of the important emerging bacterial diseases in aquaculture sector worldwide. objectives: in this study, the genetic diversity of s. iniae strains was assessed in some rainbow trout farms in iran. methods: gram positive and catalase negative bacterial isolates were first obtained from 100 trout fish farms in 8 states using routin...

background: masske is a traditional iranian butter made from yoghurt. the first aim of this study was to isolate and identify the nonlactic pathogenic microflora by culture and molecular methods of identification, and the second purpose was to identify genetic similarity of the isolated bacteria in masske. materials and methods: in order to detect pathogenic dominant indicator microorganisms, a...

Background: The emergence and re-emergence of antibiotic-resistant foodborne bacteria call for concerted efforts, especially in developing countries. Spices have been employed traditionally to improve the aroma and flavour of foods; however, they could  serve as reservoirs for the spread of potential pathogenic organisms. This study aims to investigate the public health implications of antibiot...

In the present study, 62 endophytic bacterial strains of cedar seeds (Cedrela odorataL.), collected in municipalities Huehuetán, Motozintla, and Pijijiapan state Chiapas, Mexico were isolated. The goal was to identify characteristics biotechnological interest such as biocontrol, promotion plant growth, growth aromatic compounds. identified by partial sequence 16S ribosomal gene belonging Bacill...

Extended Spectrum â-lactamase (ESBL) producing multidrug resistant bacteria complicate therapeutic management and limit treatment options. Therefore, detection of ESBL-producing multidrug resistant (MDR) pathogens has a paramount importance. Between April 2009 and January 2010, a prospective study was carried out in National Public Health Laboratory with an objective to determine the status of ...

Introduction: Bacterial resistance to β-lactam antibiotics has risen dramatically, with extended spectrum βlactamase (ESBL) contributing to this increase. Early identification of ESBL production is becoming increasingly important. Methodology: A total of 367 consecutive, urine samples from patients suspected to have UTI, were processed. All Escherichia coli and Klebsiella species isolated in si...
