In a slum community in northeastern Brazil 20% of a sample population was colonized with Entamoeba histolytica or Entamoeba dispar and 10.6% was colonized with E. histolytica alone. No correlation between seropositivity for anti-Ga1NAc lectin antibody and colonization was found. These results suggest that colonization does not necessarily produce immunity to reinfection.

Homosexual persons or human immunodeficiency virus (HIV)-infected patients frequently excrete cysts of nonpathogenic strains of Entamoeba histolytica ("Entamoeba dispar"). However, invasive amoebiasis is rare. We report two patients with AIDS and cytomegalovirus colitis in whom invasive amoebiasis was histologically diagnosed. It is concluded that E. histolytica has to be considered in HIV-infe...

The goal of this study was to develop effective and practical field sampling methods for quantification of aerial deposition of airborne conidia of Entomophaga maimaiga over space and time. This important fungal pathogen is a major cause of larval death in invasive gypsy moth (Lymantria dispar) populations in the United States. Airborne conidia of this pathogen are relatively large (similar in ...

AIM To explore the prevalence of amebiasis in inflammatory bowel disease (IBD), Crohn's disease and ulcerative colitis, in patients in Clinical hospital Mostar (Bosnia and Herzegovina, region of Herzegovina). METHODS In this study, Entamoeba histolytica/dispar prevalence was investigated in fresh faeces by native microscopy and immunochromatographic rapid assay "RIDA(®)QUICK Entamoeba test", ...

piscicidal and molluscicidal activities of aqueous extracts of many members of the family euphorbiaceae are well-known, but the toxicity potential of euphorbia turcomanica was not yet studied on any aquatic animals. an acute toxicity test was performed by using a four-day static renewal test to determine the lc 50 value of dried powder of e. turcomanica for the euryhaline fish, aphanius dispar ...

The role of calreticulin (CRT) in host-parasite interactions has recently become an important area of research. Information about the functions of calreticulin and its relevance to the physiology of Entamoeba parasites is limited. The present work demonstrates that CRT of both pathogenic E. histolytica and nonpathogenic E. dispar species specifically interacted with human C1q inhibiting the act...

Sixteen species of intestinal trematodes have been recovered from humans in Korea. They include 10 species of the family Heterophyidae (Metagonimus yokogawai, M. takahashii, Heterophyes nocens, H. heterophyes, H. dispar, Heterophyopsis continua, Pygidiopsis summa, Stellantchasmus falcatus, Centrocestus armatus, and Stictodora fuscatum); one species of Diplostomidae (Fibricola seoulensis); three...

OBJECTIVE To assess the prevalence of intestinal parasitic infections among children in highly deprived areas, and its possible association with demographic and socioeconomic indicators. MATERIAL AND METHODS From March to September 1998 in a convenience sample of 32 communities of the border region of Chiapas, Mexico, selected at random based on the level of poverty and distance from the comm...

Preventing the introduction and establishment of forest invasive alien species (FIAS) such as the Asian gypsy moth (AGM) is a high-priority goal for countries with extensive forest resources such as Canada. The name AGM designates a group of closely related Lymantria species (Lepidoptera: Erebidae: Lymantriinae) comprising two L. dispar subspecies (L. dispar asiatica, L. dispar japonica) and th...
