High-density single-nucleotide polymorphism (SNP) arrays have revolutionized the ability of genome-wide association studies to detect genomic regions harboring sequence variants that affect complex traits. Extensive numbers of validated SNPs with known allele frequencies are essential to construct genotyping assays with broad utility. We describe an economical, efficient, singlestep method for ...
The phenotypic and genotypic characterization of five clinical isolates of Leuconostoc pseudomesenteroides associated with nosocomially acquired urinary tract infections is described. All the strains were susceptible to chloramphenicol, clindamycin, erythromycin, gentamicin, and tetracycline; all were resistant to nalidixic acid, norfloxacin, and vancomycin; and all were intermediately affected...
This study of Pseudomonas aeruginosa in fecal droppings of migratory Egyptian vultures (Neophron p. percnopterus) revealed eight positive samples (n=25) by a 16S rRNA gene-based PCR in two consecutive winter seasons. Disk diffusion sensitivity testing revealed three multiple antimicrobial resistant (MAR) isolates. Genotypic characterization showed mutually exclusive exo-s and exo-u virulence ge...
Brazil has not had endemic circulation of the measles virus since 2000. Between May and June 2011, the Metropolitan Region of Campinas, State of Sao Paulo, Southeastern Brazil, reported three cases of measles. This report presents a descriptive study of the cases, control measures, and the search for a possible source and secondary cases. The genotypic characterization of the virus identified g...
background and objectives: enteropathogenic escherichia coli (epec) strains can be detected by serogrouping and the presence of enterocyte attaching- effacing (eae) gene. most epec strains belong to a certain o antigenic group. locus of enterocyte effacement (lee) pathogenicity island contains the eae gene and secretory proteins (esps) that introduce the attaching-effacing lesion. lee inserted ...
conclusions these results indicated that eaec strains isolated from iranian children with diarrhea were heterogeneous and showed high resistance rates against commonly used antibiotics, which was similar to that reported in studies performed in other countries. results significant percentage of local eaec strains carried the virulence plasmid genes and formed biofilms. in addition, these strain...
Influenza A viruses cause recurrent, seasonal epidemics and occasional global pandemics with devastating levels of morbidity and mortality. The ability of influenza A viruses to adapt to various hosts and undergo reassortment events ensures constant generation of new strains with unpredictable degrees of pathogenicity, transmissibility, and pandemic potential. Currently, the combination of fact...
We compared the results obtained by serotyping of PorB epitopes using an expanded panel of monoclonal antibodies (mAb) including mAb 7 and mAb 10, with results obtained by RFLP of rRNA genes (ribotyping). The purpose of this study was to assess the correlation between phenotypic- and genotypic- methods for typing N. meningitidis. The ribotypes obtained using ClaI or EcoRV endonucleases grouped ...
This paper is aimed at providing a comprehensive review of markers, cofactors and staging systems used for HIV disease, focusing on some aspects that nowadays could even be considered historical, and advancing in current issues such as the prognostic value of viral load measurements, viral genotypic and phenotypic characterization, and new HIV disease treatment protocols. CD4+ cell values, comb...
UNLABELLED A database and website (MPD: Mouse Phenome Database) have been developed to serve as a consolidated home for mouse strain characterization data being generated by the scientific community. Physiological, anatomical and behavioral data are being collected and integrated into a common framework for tabulation by strain and sex. Genotypic data are being collected as well. The current fo...
