The red flour beetle Tribolium castaneum has become the second most important insect model organism and is frequently used in developmental biology, genetics and pest-associated research. Consequently, the methodological arsenal increases continuously, but many routinely applied techniques for Drosophila melanogaster and other insect species are still unavailable. For example, a protocol for no...

BACKGROUND Globally, over 800 000 children under five die each year from infectious diseases caused by Streptococcus pneumoniae. To understand genetic relatedness between isolates, study transmission routes, assess the impact of human interventions e.g. vaccines, and determine infection sources, genotyping methods are required. The 'gold standard' genotyping method, Multi-Locus Sequence Typing ...

BACKGROUND Great efforts have been made to increase accessibility of HIV antiretroviral therapy (ART) in low and middle-income countries. The threat of wide-scale emergence of drug resistance could severely hamper ART scale-up efforts. Population-based surveillance of transmitted HIV drug resistance ensures the use of appropriate first-line regimens to maximize efficacy of ART programs where dr...

Genotyping of 74 Irish Helicobacter pylori isolates was performed at four different loci (vacA signal sequence and mid-region, insertion-deletion polymorphisms at the 3' end of the cag pathogenicity island, and cagA). The predominant vacA alleles and insertion-deletion motifs suggest an ancestral relationship between Irish isolates and either specific East Asian or Northern European strains. In...

Hybridization between closely related species, whether naturally occurring or laboratory generated, is a useful tool for mapping the genetic basis of the phenotypic traits that distinguish species. The development of next-generation sequencing techniques has greatly improved our ability to assign ancestry to hybrid genomes. One such next-generation sequencing technique, multiplexed shotgun geno...

objective(s): candidiasis infection caused by candida albicans has been known as a major problem in patients with immune disorders. the objective of this study was to genotype the c. albicans isolates obtained from oral cavity of patients with positive human immunodeficiency virus (hiv+) with or/and without oropharyngeal candidiasis (opc). materials and methods:a total of 100 c. albicans isolat...

background: the present study was aimed to investigate molecular diversity of echino-coccus granulosus isolates collected from human clinical samples using two mitochondrial genes cox1 and nad1 in iran . methods: forty seven human hydatid cysts were collected through surgery from two hospitals in tehran during 2010-2012. to determine the fertility of protoscoleces, the cyst fluids were subjecte...
