[Evaluation of the effect of hemolysis, bilirubin, lipemy, glucosis and natrium on mean concentration of hemoglobin (XN 2000 Sysmex)].

We evaluated the effect of haemolysis, bilirubin, lipemia, hyperglycemia and natremia on mean corpuscular haemoglobin concentration (MCHC) measured by XN 2000 (Sysmex). Our evaluation had shown than correction is necessary for haemolysis and lipemia but not for icterus. There were not possible to reproduce variation of MCHC with hyperglycemia or variation of natremia.

A novel multiple locus variable number of tandem repeat (VNTR) analysis (MLVA) method for Propionibacterium acnes.

Propionibacterium acnes plays a central role in the pathogenesis of acne and is responsible for severe opportunistic infections. Numerous typing schemes have been developed that allow the identification of phylotypes, but they are often insufficient to differentiate subtypes. To better understand the genetic diversity of this species and to perform epidemiological analyses, high throughput discriminant genotyping techniques are needed.
