See page 1103 Over recent years the mortality of young children in developing countries has been reduced by mass immunisation, but there is no cause for complacency since many currently non-immunisable threats to their health remain. One major, and previously under-appreciated, threat to physical fitness and cognitive development is intestinal nematode infestation. Despite medical advances in o...

Paleoparasitological studies using microscopy showed that Ascaris and Trichuris trichiura are the human intestinal parasites most found in archaeological sites. However, in pre-Columbian South American archaeological sites, Ascaris is rare. In this work we standardized a molecular methodology for Ascaris diagnosis directly from ancient DNA retrieved from coprolites. Using cythochrome b gene (14...

Leche de higueron is the sap of the Ficus ZuurifoZia (1, 2)) a tree which is very closely related to the domestic fig tree.’ It has been widely used as a general anthelmintic by the natives of South America and Panama and its anthelmintic action confirmed by several medical investigators who have noticed that it was particularly effective against Trichuris trichiura. The most recent work on thi...

Soil-transmitted helminth infections are among the most common infections worldwide and affect the poorest and most deprived communities. The three major soil-transmitted helminths (STHs), i.e., Ascaris lumbricoides, Trichuris trichiura and Necator americanus/Ancylostoma duodenale are among the most widespread parasites worldwide. It is estimated that more than 880 million children are in need ...

The prevalence of helminthic and protozoal infestations was studied among 778 individuals from a rural area of Northern Nigeria. The principal helminths present were Necator americanus or hookworm (46.27%, Hymenolepis nana (2.31), Enterobius vermicularis (1.29%), Taenia saginata (1.16%), Ascaris lumbricoides (0.51%), strongyloides stercorlis (2.26%) and Trichuris trichiura (2.26%). The prevalen...

Natural habitat fragmentation and reducing habitat quality have resulted in an increased appearance of Japanese macaques, Macaca fuscata (Gray, 1870), in suburban areas in Japan. To investigate the risk of zoonotic infections, a coprological survey of helminth eggs passed by wild Japanese macaques was carried out in 2009 and 2010 in Shiga Prefecture, Japan. Microscopic examination found helmint...

Introducción: Las infecciones por helmintos impactan gran parte de la población infantil los países en desarrollo, afectando comunidades urbanas y rurales y, están ampliamente relacionadas con condiciones medioambientales, socioeconómicas salubridad deficientes. Objetivo: Comparar efectividad las técnicas diagnóstico directo para geohelmintiasis, causadas Ascariasis lumbricoides, Trichuris tric...

The diagnosis of parasitic worm (helminth) infections requires specialized laboratory settings, but most affected individuals reside in locations without access to such facilities. We tested two portable microscopic devices for the diagnosis of helminth infections in a cross-sectional survey in rural Côte d'Ivoire. We examined 164 stool samples under a light microscope and then re-examined with...
