Epidemiological analysis of eosinophilia and elevation of immunoglobulin E as a predictable and relative risk of enteroparasitosis.

Introduction: among the intestinal parasites, the helminthiasis occupies a prominent position in Brazil, since it worsens malnutrition and the gives rise to neurovegetative disorders. Helminths like Ascaris lumbricoides, Enterobius vermicularis, hookworm, Trichuris trichiura and Strongyloides stercoralis stand out due to several factors that modulate the immune response of individuals. Among the protozoa are Giardia lamblia, Entamoeba histolytica.

Results of the GEP-ISFG collaborative study on the Y chromosome STRs GATA A10, GATA C4, GATA H4, DYS437, DYS438, DYS439, DYS460 and DYS461: population data.

The Spanish and Portuguese ISFG Working Group (GEP-ISFG) carried out a collaborative exercise in order to asses the performance of two Y chromosome STR tetraplexes, which include the loci DYS461, GATA C4, DYS437 and DYS438 (GEPY I), and DYS460, GATA A10, GATA H4 and DYS439 (GEPY II). The groups that reported correct results in all the systems were also asked to analyse a population sample in order to evaluate the informative content of these STRs in different populations. A total of 1020 males out of 13 population samples from Argentina, Brazil, Costa Rica, Macao, Mozambique, Portugal and Spain were analysed for all the loci included in the present study.

Sequence variation of new alleles at the short tandem repeat D19S253 locus.

This paper reports the sequences of two new alleles identified in a population database study on the short tandem repeat D19S253 locus. A Portuguese Caucasian population and a Portuguese African population were studied. Forty-four selected alleles were sequenced and 11 different alleles were found.
