pFGE is the paralog of the formylglycine-generating enzyme (FGE), which catalyzes the oxidation of a specific cysteine to C -formylglycine, the catalytic residue in the active site of sulfatases. The enzymatic activity of sulfatases depends on this posttranslational modification, and the genetic defect of FGE causes multiple sulfatase deficiency. The structural and functional properties of pFGE...

The aim of this study was to evaluate the genotypic relationships among 40 Streptococcus uberis isolated from bovine mastitis by using pulsed-field gel electrophoresis (PFGE). Additionally, the association between PFGE patterns and virulence profiles was investigated. The isolates exhibited 17 PFGE patterns. Different strains were found within and among herds; however, a low number of isolates ...

Corynebacterium striatum is a potentially pathogenic microorganism with the ability to produce outbreaks of nosocomial infections. Here, we document a nosocomial outbreak caused by multidrug-resistant (MDR) C. striatum in Rio de Janeiro, Brazil. C. striatum identification was confirmed by 16S rRNA and rpoB gene sequencing. Fifteen C. striatum strains were isolated from adults (half of whom were...

INTRODUCTION Clonal relationships of Klebsiella pneumoniae strains obtained during an epidemic and after a one-year post-epidemic (non-epidemic) period in the same neonatal intensive care unit (NICU) using pulsed-field gel electrophoresis (PFGE) and repetitive polymerase chain reaction (rep-PCR) by the DiversiLab (DL) system were investigated, and the results of both molecular techniques were e...

Knowledge about molecular epidemiology of B. henselae is important for recognizing the geographical distribution of strains and identification of isolates virulent for humans. Eleven Polish feline B. henselae isolates were typed, using 2 different techniques: pulse-field gel electrophoresis (PFGE) and multiple-locus variable-number tandem repeat analysis (MLVA). PFGE analysis distinguished 6 di...

Recent data from microarray analysis have shown that integrated prophages are the most frequent sources of genomic variation between different strains of Salmonella enterica serovar Typhimurium (S. Typhimurium). This led us to hypothesize that PCR detection of the integrated prophages might be an efficient typing tool that could be used as an alternative to PFGE. In this study, we optimized fou...

Denmark has a high incidence of invasive listeriosis (0.9 cases/100,000 population in 2012). We analyzed patient data, clinical outcome, and trends in pulsed-field gel electrophoresis (PFGE) and multilocus sequence typing (MLST) of Listeria monocytogenes strains isolated in Denmark during 2002-2012. We performed 2-enzyme PFGE and serotyping on 559 isolates and MLST on 92 isolates and identified...

Cholera posed a significant threat causing outbreaks/epidemics with high morbidity and mortality in Odisha. This study envisages the characterisation of isolated pathogen from two cholera outbreaks reported 2018 2019 Bargarh Rayagada districts Odisha respectively. Vibrio cholerae O1 were following standard techniques. The different virulent drug resistant genes detected by multiplex PCR assays;...

background: re-emergence of pertussis has been reported in iran despite a high rate of vaccination coverage. low efficacy of the vaccine might be due to the genetic divergence between clinical versus vaccine strains. in the current study, the genetic profiles of clinical isolates and vaccine strains of bordetella pertussis (b. pertussis) were assessed by using pulsed field gel electrophoresis (...

In this study, the discriminatory power of pulsed field gel electrophoresis (PFGE) and random amplified polymorphic DNA (RAPD) methods for subtyping of 54 clinical isolates of Klebsiella pneumoniae were compared. All isolates were typeable by RAPD, while 3.6% of them were not typeable by PFGE. The repeatability of both typing methods were 100% with satisfying reproducibility (≥ 95%). Although t...
