Genetic Variation in the Gene Is Associated with Infection and Host Humoral Response to Infection.

This study aims to assess the potential association of MBL2 gene single nucleotide polymorphisms (SNPs) to Chlamydia trachomatis infection. We analysed a selected sample of 492 DNA and serum specimens from Dutch Caucasian women. Women were categorized into four groups of infection status based on the results of DNA and antibody tests for C.

Development of a multiplex real-time PCR assay for the rapid diagnosis of neonatal late onset sepsis.

The diagnosis of late onset sepsis (LOS), a severe condition with high prevalence in preterm infants, is hampered by the suboptimal sensitivity and long turnaround time of blood culture. Detection of the infecting pathogen directly in blood by PCR would provide a much more timely result. Unfortunately, PCR-based assays reported so far are labor intensive and often lack direct species identification.

Comparison of pathogen DNA isolation methods from large volumes of whole blood to improve molecular diagnosis of bloodstream infections.

For patients suffering from bloodstream infections (BSI) molecular diagnostics from whole blood holds promise to provide fast and adequate treatment. However, this approach is hampered by the need of large blood volumes. Three methods for pathogen DNA isolation from whole blood were compared, i.

Mannose-binding lectin gene polymorphisms in relation to periodontitis.

Aim: To investigate the correlation of six functional polymorphisms in the MBL gene with MBL plasma levels in relation to periodontitis.

Material And Methods: A total of 92 periodontitis patients and 70 controls, all of Caucasian origin, were included. Patients and controls were genotyped for the L/H, X/Y, P/Q, A/D, A/B and A/C polymorphisms.

Mannose-binding lectin in term newborns and their mothers: genotypic and phenotypic relationship.

Functional mannose-binding lectin (f-MBL) plays an important role in the innate neonatal immune system. We studied the origin of f-MBL in umbilical cord blood (UCB) by measuring maternal MBL (n=47), collected before elective cesarean section, and neonatal MBL (n=43) in arterial umbilical cord blood. In a subgroup, arterial and venous UCB MBL levels were measured.

Analysis of multiple single nucleotide polymorphisms (SNP) on DNA traces from plasma and dried blood samples.

Reliable analysis of single nucleotide polymorphisms (SNPs) in DNA derived from samples containing low numbers of cells or from suboptimal sources can be difficult. A new procedure to characterize multiple SNPs in traces of DNA from plasma and old dried blood samples was developed. Six SNPs in the Mannose Binding Lectin 2 (MBL2) gene were chosen as targets for analysis.

Detection of Mycobacterium tuberculosis complex with Real Time PCR: comparison of different primer-probe sets based on the IS6110 element.

The sensitivity and specificity to detect Mycobacterium tuberculosis complex of four Real Time PCR primer-probe sets was compared. Three sets targeted nearly the same location on the IS6110 sequence and set 4 targeted a location 200 bp downstream on IS6110. Real Time PCR's with sets 1, 2 and 3 were carried out with co-amplification of a modified target as an internal amplification control.

Real-time PCR detection of ruminant DNA.

To control the spread of bovine spongiform encephalopathy, several DNA methods have been described for the detection of the species origin of meat and bone meal. Most of these methods are based on the amplification of a mitochondrial DNA segment. We have developed a semiquantitative method based on real-time PCR for detection of ruminant DNA, targeting an 88-bp segment of the ruminant short interspersed nuclear element Bov-A2.
