Over 4.5 billion people are at risk of infection with soil transmitted helminths and there are concerns about the development of resistance to the handful of frontline nematocides in endemic populations. We investigated the anti-nematode efficacy of a series of polypyridylruthenium(II) complexes and showed they were active against L3 and adult stages of Trichuris muris, the rodent homologue of ...

Soil-transmitted helminths (STH), namely Ascaris, Trichuris and hookworms (Ancylostoma and Necator), present a global health problem to about a half of the earthos population. In the Republic of Korea, STH were highly prevalent and were considered a high priority target for national control. To promote the control, a non-governmental organization named Korea Association for Parasite Eradication...

background: the aim of the study was to determine the helminthic species occurring in great gerbil rhombomys opimus collected from maraveh tappeh, golestan province, northeast iran. methods : during 2010-2011, a total of 77 r. opimus were captured from rural areas of maraveh tap-peh, golestan province, using sherman live traps and examined for infectivity with any larva or adult stages of helmi...

Trichuris muris infection is an ideal model for defining T-cell-driven immunity, and also provides essential insights that may impact on potential helminth therapies currently in development. Conflicting host variables determine the efficiency of such treatments and we have identified host-derived sex steroid hormones as key factors in the development of immunity. The female-associated hormone ...

Stool examination by sedimentation method in 82 homeless individuals living in the streets of Rio de Janeiro City, revealed Ascaris lumbricoides eggs in 40 (48.85%), Trichuris trichiura in 27 (32.9%) and hookworm in 7 (8.5%).

Paleoparasitological findings about human occupation and their domestic animals, from Gallo-Roman period up to recent times, were described at the archaeological site of "Place d'Armes", Namur, Belgium, by preventive archaeological excavations. Organic sediment samples from cesspools, latrines and structures-like were analyzed and revealed intestinal parasite eggs (helminthes) in all of the dif...

A paleoparasitological study was carried out on 2 lead coffins recovered from the Roman site of Jaunay-Clan (near Poitiers, France). For the first time, this particular type of burial gave positive parasitological results, and eggs of the whipworm Trichuris trichiura were identified in 1 individual. In the present case, thanatomorphose associated with funerary practices may explain the scarcity...
