Abstract
A population-representative lot quality assurance sampling (LQAS) survey was conducted in 2009 to determine the prevalence of intestinal helminth infections among schoolchildren across Osh oblast, Kyrgyzstan. The diagnostic approach consisted of duplicate Kato-Katz thick smears from a single stool s...

Abstract
We investigated what determines the level of taxonomic resolution achieved. Identification of all helminths down to species level was achieved in only one-third of surveys, whereas all taxa were identified at least to genus level in two-thirds of surveys. The species richness of a parasite community...

Abstract
In January-March 2000, the impact of intestinal helminthiases on the nutritional status of 749 pupils (353 boys and 396 girls) attending public primary schools in the Ife Central local government area of Osun state, in south-western Nigeria, was investigated. Demographic, socio-economic and other re...

Abstract
We investigated the factors providing structure to the helminth communities of 182 loggerhead sea turtles, Caretta caretta, collected in 6 localities from Central and Western Mediterranean. Fifteen helminth taxa (10 digeneans, 4 nematodes and 1 acanthocephalan) were identified, of which 12 were spec...

Abstract
The results from this study showed that the prevalence of intestinal helminthiasis was significantly affected by various behavioural risk factors. The rate of helminthic infection varied significantly with hand washing habits after defeacation (chi2 = 75.77; df= 2; p = 0.001) and with different habi...

Abstract
We investigated helminth parasitism in 2 South American rodent species, Ctenomys australis and C. talarum (Octodontidae), to determine whether the unusual solitary and subterranean nature of these hosts would impact their patterns of infection. We applied generalized linear models to infection data...

Abstract
We have characterized SL RNAs from Prionchulus punctatus. Surprisingly, this revealed the presence of a set of SLs that show clear sequence similarity to the SL2 family of spliced leaders, which have previously only been found within the rhabditine group (which includes C. elegans). Expression of on...

Abstract
We conducted a cross-sectional study of 880 children in 10 Nicaraguan primary schools located in four provinces. We aimed to establish the prevalence and intensity of soil-transmitted helminth infections and to investigate the factors associated with helminthiasis. Almost half (46%) of the children...

Abstract
The alcoholic extract of Lysimachia ramosa Wall (Primulaceae) was tested in vitro against helminth parasites, Fasciolopsis buski and Ascaris suum, from porcine hosts and Raillietina echinobothrida from domestic fowl. The live adult parasites, collected from a freshly autopsied host, were exposed to...

Abstract
We have known since 1991 how to induce naive CD4 T cells to differentiate in vitro into Th2 cells and, over the ensuing years, a comprehensive picture of the molecules involved in this important process has emerged. GATA3 and STAT5 are both essential for in vitro differentiation, stimulating naive c...

Abstract
Our findings show that, after an environmental disaster, the behaviour of helminth species might be related to their pre-catastrophe presence, their biological cycles, the host's immunological condition, the change of host dynamics, the direct effects of the perturbation, and the processes related t...

Abstract
Peroxiredoxin (Prx) belongs to a peroxidase family of antioxidant enzymes distributed ubiquitously in aerobic organisms. It plays an important role in the defense of reactive oxygen species (ROS) and reactive nitrogen species (RNS) produced by parasite itself and the host immune cells. The classific...

Abstract
729 and 890 children aged 7-14 years (mean = 10.4 y, SD = 0.05 y) were analysed over the first and the second cohorts, respectively. The adjusted reductions of the prevalence and incidence rates at the second in relation to the first cohort were 27% and 34%, 25% and 32%, 33% and 26%, and 82% and 42%...

Abstract
As a diagenetic progress, bioturbation influences solute exchange across the sediment-water interface (SWI). Different benthic animals have various mechanical activities in sediment, thereby they may have different effects on solute exchange across the SWI. This laboratory study examined the impacts...

Abstract
Two hundred and twenty-one children (57.8%) of the 384 children studied had intestinal parasites. Ascaris lumbricoides, Ancylostoma duodenale and Trichuris trichura were the commonest parasites found. The relationship between intestinal parasite infestation and diarrhea in past 2 months (X2 =19.5, d...

Helminth parasites are of considerable medical and economic importance. Studies of the immune response against helminths are of great interest in understanding interactions between the host immune system and parasites. Effector immune mechanisms against tissue-dwelling helminths and helminths locali...

Analysis of original long-term investigation (1980-2006) and literary data on the helminthofauna of reptiles in the Republic of Belarus is carried out. Seven species of reptiles were examined on Southern Belarus, 32 species of helminthes were found with total infestation 72.7%. It is established tha...
