Hundreds of millions of people are infected with helminths and intestinal protozoa, particularly children in low- and middle-income countries. Preventive chemotherapy is the main strategy to control helminthiases. However, rapid re-infection occurs in settings where there is a lack of clean water, sanitation and hygiene. In August and September 2014, we conducted a cross-sectional epidemiological survey in 56 communities of three departments of south-central Côte d'Ivoire. Study participants were invited to provide stool and urine samples...

BACKGROUND: Intestinal protozoa are common opportunistic infections in HIV patients. Longitudinal studies on either the clinical relevance, or the effect of immune reconstitution by anti-retroviral therapy on intestinal protozoan infections are children is lacking however. This study investigates prevalence and clinical relevance of intestinal protozoa in HIV-infected Malawian children prior to and during their first year of ART. METHODS: Stool samples collected at enrolment and during follow-up were tested for non-opportunistic (Giardia lamblia, Dientamoeba fragilis, Entamoeba histolytica) and opportunistic protozoa (Entroctytoon bieneusi, Encephalitozoon spp...

Two distinct clusters of gastroenteritis due to Salmonellae and Entamoeba histolytica (EH) were identified using a multiplex gastrointestinal pathogen panel (GPP) at a tertiary-care cancer center. Despite temporo-spatial overlap, our investigation did not corroborate transmission or true infection. In clinical practice, GPPs may render false-positive results.Infect Control Hosp Epidemiol 2018;1-4.

We have previously shown that the C-terminal region of the intermediate subunit of Entamoeba histolytica galactose- and N-acetyl-D-galactosamine-inhibitable lectin (C-Igl) is a useful antigen for serodiagnosis of amebiasis. An immunochromatographic kit was developed using fluorescent silica nanoparticles coated with C-Igl prepared in Escherichia coli. Samples for examination were added to the freeze-dried particles and then applied to the immunochromatographic device, in which a test line on the membrane was also coated with C-Igl...

Entamoeba histolytica is a protozoan parasite that affects a large proportion of the world's population and causes amoebic dysentery and extra-intestinal disease. Many individuals remain asymptomatic during colonisation; in 10% of individuals, the parasite breaks through the mucosal barrier and leads to invasive disease. An eight-month-old girl who was evaluated for hypo-albuminaemia and was diagnosed with amoebic colitis is reported. To the best of our knowledge, this is the first report of hypo-albuminaemia owing to amoebic colitis in any age group...

E. histolytica, a protozoan parasite is the causative agent of amoebiasis in human beings. It exists in two different forms - the motile trophozoite form which undergoes encystation under starvation conditions to form the non-motile, osmotically resistant cyst form. Cellular stresses stimulate several signaling cascades which assist the parasite in counter-attacking such conditions thereby, promoting cell survival. To study the stress-associated pathways activated during encystation, we have used Entamoeba invadens, a reptilian parasite as a model organism because of its ability to undergo encystation under in vitro conditions...

INTRODUCTION: Amoebiasis is a cosmopolitan disease and the third most deadly of parasitic diseases. Entamoeba histolytica is the only one to be pathogenic. Its transmission is not only related to the faecal peril but also sexual, with cases described among men who have sex with men. A case of unusual sexual transmission is described in this article, aiming to discuss the impact of these ways of transmitting amoebiasis on patient management. CASE REPORT: We describe the case of an amebic liver abscess in a 27-years-old man who did not travel in endemic areas...

Antibodies recognize protein targets with great affinity and specificity. However, posttranslational modifications and the presence of intrinsic disulfide-bonds pose difficulties for their industrial use. The immunoglobulin fold is one of the most ubiquitous folds in nature and it is found in many proteins besides antibodies. An example of a protein family with an immunoglobulin-like fold is the Cysteine Protease Inhibitors (ICP) family I42 of the MEROPs database for protease and protease inhibitors. Members of this protein family are thermostable and do not present internal disulfide bonds...

Entamoeba histolytica has been rarely reported as superadded infection over carcinomatous growth on rectal brushings. We present a case of 68-year-old male who presented with abdominal pain and bleeding per rectum who was found to have an ulceroproliferative growth on sigmoidoscopy. Rectal brushings revealed coexistence of E. histolytica with malignant cells of adenocarcinoma. No organism was detected on biopsy of the tumor, which also showed adenocarcinoma, because of possible surface colonization of the tumor by Entamoeba ...

The human protozoan pathogens possess the essential metalloenzyme arginase (Arg) which catalyses the catabolism of l-arginine to l-ornithine and urea. This being the first committed step in polyamine biosynthesis is a potential drug target for protozoan diseases. In pathogenic organisms, arginase plays a crucial role in depleting host l-arginine, a substrate for nitric oxide synthase (NOS) that participates in protective immunity, thereby evading host immune response. In this study, the metal binding spectrum of EhArg has been determined...

Enteric α-defensins, termed cryptdins (Crps) in mice, and lysozymes secreted by Paneth cells contribute to innate host defense in the ileum. Antimicrobial factors including lysozymes and β-defensins are often embedded in luminal glycosylated colonic Muc2 mucin secreted by goblet cells that form the protective mucus layer critical in gut homeostasis and pathogen invasion. In this study we investigated ileal innate immunity against Entamoeba histolytica (Eh ), the causative agent of intestinal amebiasis, by inoculating parasites in closed ileal loops in Muc2+/+ and Muc2-/- littermates and quantifying Paneth cell localization (lysozyme expression) and function (Crps secretion)...

The protist parasite Entamoeba histolytica causes amoebiasis, a major public health problem in developing countries and a major cause of morbidity and mortality. Invasive infection in amoebiasis mostly affects intestinal epithelial cell lining, but can also involve other organs, such as liver, lungs or brain. Phagocytosis is an essential mode of nutrition in amoeba and has often been associated with virulence behaviour of E. histolytica. E. histolytica possesses a highly dynamic and actin-rich cytoskeleton that is thought to be involved in many processes, such as motility, pseudopod formation and pathogenesis...

Due to their archaic life style and microbivor behavior, amoebae may represent a source of antimicrobial peptides and proteins. The amoebic protozoon Dictyostelium discoideum has been a model organism in cell biology for decades and has recently also been used for research on host-pathogen interactions and the evolution of innate immunity. In the genome of D. discoideum , genes can be identified that potentially allow the synthesis of a variety of antimicrobial proteins. However, at the protein level only very few antimicrobial proteins have been characterized that may interact directly with bacteria and help in fighting infection of D...

Not long ago, protists were considered one of four eukaryote kingdoms, but recent gene-based phylogenies show that they contribute to all nine eukaryote subdomains. The former kingdoms of animals, plants and fungi are now relegated to lower ranks within subdomains. Most unicellular protists respond to adverse conditions by differentiating into dormant walled cysts. As cysts, they survive long periods of starvation, drought and other environmental threats, only to re-emerge when conditions improve. For protists pathogens, the resilience of their cysts can prevent successful treatment or eradication of the disease...

Background: Amoebiasis, the cause of dysentery and extra-intestinal abscesses, now becomes second fatal parasitic disease in the world. As routine microscopic diagnosis cannot differentiate causative Entamoeba histolytica from non-pathogenic E. dispar and E. moshkovskii , better diagnosis has to be searched. Materials and Methods: Multiplex single round PCR was tested and compared with results of microscopy of wet preparation on 30 samples of diarrheic stools and extra intestinal lesions from amoebiasis suspected patients...
