INTRODUCTION This study evaluated the presence of pathogenic human parasites on field-grown strawberries in the Federal District of Brazil. METHODS A total of 48 samples of strawberries and 48 soil samples from 16 properties were analyzed. RESULTS Contaminated strawberries were detected in 56% of the properties. Schistosoma mansoni, Ascaris lumbricoides or Ascaris suum, Balantidium coli, En...
The intervening sequences in the large ribosomal RNA gene of Ascaris lumbricoides var. suum show many similarities to the type I insertions, previously found only in some insect species. They include structural features, but also a presumed transcriptional inactivity in vivo: No transcript of the rDNA intervening sequence in A. lumbricoides could be detected in Northern and dot blot hybridizati...
We describe 35 microsatellite markers from the human parasitic nematode Ascaris lumbricoides. We found 7 sex-linked markers and demonstrate that 26 autosomal loci can be scored reliably. These markers have high genetic variability and provide the tools to address multiple questions concerning the epidemiology, fine-scale genetic structure, host specificity, and mating systems of this parasite.
