Development and evaluation of a multiple-locus variable-number tandem-repeats analysis assay for subtyping Salmonella Typhi strains from sub-Saharan Africa [PDF]
Purpose: Molecular epidemiological investigations of the highly clonal Salmonella enterica subspecies enterica serovar Typhi (S. Typhi) are important in outbreak detection and in tracking disease transmission.

First Worldwide Proficiency Study on Variable-Number Tandem-Repeat Typing of Mycobacterium tuberculosis Complex Strains [PDF]
Although variable-number tandem-repeat (VNTR) typing has gained recognition as the new standard for the DNA fingerprinting of Mycobacterium tuberculosis complex (MTBC) isolates, external quality control programs have not yet been developed.

Abstract DNA methylation controls DNA accessibility to transcription factors and other regulatory proteins, thereby affecting gene expression and hence cellular identity and function. As epigenetic modifications control the transcriptome, epigenetic dysfunction is strongly associated with pathological conditions and ageing.

Development of Multi-Locus Variable Number Tandem Repeat Analysis for Outbreak Detection of Neisseria meningitidis [PDF]
Neisseria meningitidis is a major cause of septicemia and meningitis worldwide. Traditional typing methods like pulsed-field gel electrophoresis (PFGE) for identifying outbreaks are subjective and time consuming.

Mycobacterium tuberculosis lineage: a naming of the parts [PDF]
There have been many reports of groups of related Mycobacterium tuberculosis strains described variously as lineages, families or clades. There is no objective definition of these groupings making it impossible to define relationships between those ...

Aspergillus flavus is second only to A. fumigatus in causing invasive aspergillosis and it is the major agent responsible for fungal sinusitis, keratitis and endophthalmitis in many countries in the Middle East, Africa and Southeast Asia.

AIRE's Complex Role Beyond Promiscuous Gene Expression
ABSTRACT Central tolerance, established in the thymus, ensures T cells are nonreactive to self‐antigens while maintaining a functional immune repertoire. Medullary thymic epithelial cells (mTECs) and thymic dendritic cells (DCs) play a crucial role in this mechanism by orchestrating the selection and deletion of autoreactive thymocytes, a process ...

Intra-Species Diversity and Panmictic Structure of Cryptosporidium parvum Populations in Cattle Farms in Northern Spain. [PDF]
The intra-herd and intra-host genetic variability of 123 Cryptosporidium parvum isolates was investigated using a multilocus fragment typing approach with eleven variable-number tandem-repeat (VNTR) loci and the GP60 gene.
