over moist, somewhat uneven ground, favouring the accumulation of water here and there, soon lead to profuse development of larvse. These favourable circumstances are found whenever latrines are absent. The excrementa lie scattered in large masses near human dwellings, especially in swampy soil frequently trampled on by men and animals, without any outflow of water. This is the peculiar home of...

OBJECTIVE Establishing the presence of zoonotic gastrointestinal nematodosin soil samples in recreational areas in Suba (one of the largest localities of Bogotá, Colombia) between July 2005 and June 2006. METHODOLOGY The presence of several gastrointestinal parasites' eggs, larvae and oocysts were determined by initial soil sedimentation and later flotation with Sheather solution; some of the...

Historically, the diagnosis of soil-transmitted helminths (STHs) (e.g., Strongyloides stercoralis, Trichuris trichiura, Ancylostoma duodenale, Necator americanus, and Ascaris lumbricoides) has relied on often-insensitive microscopy techniques. Over the past several years, there has been an effort to use molecular diagnostics, particularly quantitative polymerase chain reaction (qPCR), to detect...

Canine and feline hookworm infection is endemic in many countries with zoonotic transmission representing a potentially significant public health concern. However, there is limited data available on the zoonotic transmission of canine and feline hookworms in China. This study was conducted to evaluate the zoonotic risk of Ancylostoma ceylanicum isolated from stray dogs and cats in Guangzhou, so...

We studied the basis of inhibition of polymorphonuclear leukocyte (PMN) adhesion induced by neutrophil inhibitory factor (NIF), a 41-kDa CD11/CD18 beta(2) integrin-binding protein isolated from the canine hookworm (Ancylostoma caninum). NIF blocked PMN adhesion in a concentration-dependent manner with complete blockade occurring at approximately 10 nM NIF. Because CD11a and CD11b beta(2) integr...

It is estimated that in Latin America and the Caribbean (LAC) at least 13.9 million preschool age and 35.4 million school age children are at risk of infections by soil-transmitted helminths (STH): Ascaris lumbricoides, Trichuris trichiura and hookworms (Necator americanus and Ancylostoma duodenale). Although infections caused by this group of parasites are associated with chronic deleterious e...

Prison inmates are among the high risk population for dangerous helminthes infections and other contagious diseases. This study was undertaken to determine the prevalence of intestinal helminthiasis among prison inmates in Jos, Plateau State, Nigeria. Fresh stool samples from 300 inmates in Jos central prison were screened for helminthes infections using Formal-ether concentration and Kato-Katz...

Irritable bowel syndrome (IBS) is a gastrointestinal disorder characterized by chronic abdominal pain and altered bowel habits in the absence of any organic cause. As the clinical manifestations are very diverse and associated with nonspecific symptoms, research seeking to identify organic causes to rule out IBS and to enable differential diagnosis is required. A 24-year-old man was referred to...

Hookworm (Necator americanus, Ancylostoma duodenale) infection are common in tropical and subtropical countries. These still an neglected disease rural areas,leading to severe iron deficiency anemia even mortality. Here we present a case from tertiary care center northern India of 3 year old child with progressive complaint pallor generalised body swelling. On upper gastrointestinal gastroscopy...
