Mycobacterium ulcerans (M. ulcerans), the causative agent of the devastating skin disease Buruli ulcer (BU), is characterized by an extremely low level of genetic diversity. Recently, we have reported the first discrimination of closely related M. ulcerans variants in the BU endemic Densu River Valley of Ghana. In the study real-time PCR-based single nucleotide polymorphism (SNP) typing at 89 p...

• A MDR Staphylococcus pseudintermedius strain CAM1 was characterized by WGS. S. belonged to st551. The also harboured tet K, which is extremely rare in this species. To determine the draft genome sequence and analyse genetic features of a clinical isolate according main typing schemes available, with special focus on antibiotic resistance. isolated from case otitis externa dog. Its identity pa...

We have used DNA hybridization techniques employing restriction fragment length polymorphisms (RFLPs) to quantitate the level of donor cell engraftment in bone marrow transplantation recipients. The genetic origin of the bone marrow cells and various peripheral blood populations was analyzed in 14 patients. We found at least one informative polymorphism for each donor-recipient pair. Additional...

Large-scale genotyping of Mycobacterium tuberculosis is especially challenging, as the current typing methods are labor-intensive and the results are difficult to compare among laboratories. Here, automated typing based on variable-number tandem repeats (VNTRs) of genetic elements named mycobacterial interspersed repetitive units (MIRUs) in 12 mammalian minisatellite-like loci of M. tuberculosi...

Multiresistant Klebsiella pneumoniae caused a nosocomial outbreak. Resistance patterns of the presumed outbreak isolates varied among and within patients. In order to control the outbreak, screening for extended-spectrum beta-lactamase (ESBL)-producing K. pneumoniae was commenced. A number of susceptible K. pneumoniae strains were stored to serve as controls in genetic strain typing. Typing by ...

INTRODUCTION Brucellosis is one of the most important zoonotic diseases that affects multiple livestock species and causes great economic losses. The highly conserved genomes of Brucella, with > 90% homology among species, makes it important to study the genetic diversity circulating in the country. METHODOLOGY A total of 26 Brucella spp. (4 reference strains and 22 field isolates) and 1 B. m...

OBJECTIVE To devise a new and simple technique to help select normal embryos that are human leukocyte antigen (HLA) matched to their affected siblings for diseases, such as beta-thalassemia or sickle cell anemia, which are common in this part of the world. METHODS This study was conducted between March 2008 and April 2011 at the preimplantation Genetic Diagnosis Laboratory, Saad Specialist Ho...

Human enteroviruses have traditionally been typed according to neutralization serotype. This procedure is limited by the difficulty in culturing some enteroviruses, the availability of antisera for serotyping, and the cost and technical complexity of serotyping procedures. Furthermore, the impact of information derived from enterovirus serotyping is generally perceived to be low. Enteroviruses ...

Assessing the relatedness of strains isolated from patients and their environment is instrumental in documenting the source of preventable health care-associated life-threatening Aspergillus flavus human infection clusters. The present study aimed at identifying and selecting suitable microsatellite markers for A. flavus typing. This typing scheme was then applied to investigate the A. flavus e...

In clinical settings, rapid and accurate characterization of pathogens is essential for effective treatment of patients; however, subtle genetic changes in pathogens which elude traditional phenotypic typing may confer dangerous pathogenic properties such as toxicity, antibiotic resistance, or virulence. Existing options for molecular typing techniques characterize the critical genomic changes ...
