Rapid microarray-based DNA genoserotyping of Escherichia coli

In this study, an improvement in the oligonucleotide‐based DNA microarray for the genoserotyping of Escherichia coli is presented. Primer and probes for additional 70 O antigen groups were developed....

A DNA microarray facilitates the diagnosis of Bacillus anthracis in environmental samples

Aims: In order to improve the diagnosis of Bacillus anthracis in environmental samples, we established a DNA microarray based on the ArrayTube technology of Clondiag. Methods and Results: Total DNA of...

Broad spectrum reactivity versus subtype specificity-Trade-offs in serodiagnosis of influenza A virus infections by competitive ELISA

Avian influenza viruses (AIVs) of the H5 and H7 subtypes can cause substantial economic losses in the poultry industry and are a potential threat to public health. Serosurveillance of poultry populations...

Detection of herpesvirus and adenovirus co-infections with diagnostic DNA-microarrays

In immunocompromised patients, the diagnosis of infections with herpesviruses and adenoviruses relies mainly on PCR amplification of viral genomic DNA from clinical samples. In the case of co-infections...

Rapid haemagglutinin subtyping and pathotyping of avian influenza viruses by a DNA microarray

Rapid and reliable methods are fundamental for the comprehensive characterization of emerging and evolving avian influenza viruses. Although microarrays provide new possibilities with their parallel approach,...

A multiplex real-time PCR for the direct, fast, economic and simultaneous detection of the carbapenemase genes blaKPC, blaNDM, blaVIM and blaOXA-48

A novel multiplex real-time PCR was designed to detect the clinically most important carbapenemase genes, blaKPC, blaVIM, blaNDM and blaOXA-48. The multiplex assay was verified testing genomic DNA of 24...

Serogenotyping and emergence of extended-spectrum beta-lactamase genes in non-typhoidal Salmonella: first report from Saudi Arabia

Genotyping of Staphylococcus aureus associated with nasal colonization among healthcare workers using DNA microarray

Introduction: Healthcare workers (HCWs) colonized with Staphylococcus aureus may serve as a reservoir of infection. This study was carried to determine the genetic make-up of S. aureus nasal colonizers...

In vitro activity of ceftaroline against mecC-positive MRSA isolates

Ceftaroline is a new cephalosporin with activity against methicillin-resistant Staphylococcus aureus (MRSA). A collection of 17 clinical and veterinary mecC-positive MRSA isolates was tested to evaluate...

Staphylococci in cattle and buffaloes with mastitis in Dakahlia Governorate, Egypt

The aim of this study was to provide the first detailed insight into the population structure of Staphylococcus aureus in one modern dairy farm (Gamasa) and several household cows and buffaloes in Dakahlia...
