Comparative analysis of microRNA profiles between adult Ascaris lumbricoides and Ascaris suum
BACKGROUND The parasitic nematodes Ascaris lumbricoides and A. suum are of great public health and economic significance, and the two taxa were proposed to represent a single species. miRNAs are known with functions of gene regulations at post-transcriptional level. RESULTS We herein compared the miRNA profiles of A. lumbricoides and A. suum female adults by Solexa deep sequencing combined wi...
متن کاملMeiotic Structures in the Animal-Parasitic Nematode Ascaris megalocephala: Synaptonemal Complexes, Recombination Nodules, and Centrioles.
Two synaptonemal complexes (SCs) were present in the pachytene nuclei of Ascaris megalocephala. The SC was tripartite and comprised of two lateral elements (25 nm) with a striated central element (25 nm) and a central region of 65 nm. Spherical recombination nodules were observed to be associated only with the central element, although they are non-existent in the related A. lumbricoides var. s...
متن کاملEnzyme Localization in the Anaerobic Mitochondria of Ascaris Lumbricoides
Mitochondria from the muscle of the parasitic nematode Ascaris lumbricoides var. suum function anaerobically in electron transport-associated phosphorylations under physiological conditions. These helminth organelles have been fractionated into inner and outer membrane, matrix, and intermembrane space fractions. The distributions of enzyme systems were determined and compared with corresponding...
متن کاملPaleoparasitological remains revealed by seven historic contexts from "Place d'Armes", Namur, Belgium.
Human occupation for several centuries was recorded in the archaeological layers of "Place d'Armes", Namur, Belgium. Preventive archaeological excavations were carried out between 1996/1997 and seven historical strata were observed, from Gallo-Roman period up to Modern Times. Soil samples from cesspools, latrines, and structures-like were studied and revealed intestinal parasite eggs in the dif...
متن کاملTitle: Ascaris and Ascariasis
Ascaris lumbricoides and Ascaris suum are widespread parasitic nematodes of humans and pigs respectively. Recent prevalence data suggests that approximately 1.2 billion people are infected. Adult worms exhibit an overdispersed frequency distribution in their hosts and individuals harbouring heavy burdens display associated morbidity. In this review, we describe the parasite, its distribution an...
