Entameba histolytica causes amebiasis, which includes both intestinal and extraintestinal amebiasis. E. histolytica causes 34 million to 50 million symptomatic cases of amebiasis worldwide every year, causing 40 thousand to 100 thousand deaths annually. E. histolytica, the pathogenic species of amebae is indistinguishable in its cyst and trophozoite stages from those of E. moshkovskii, a free-living ameba, and E. dispar, a non-invasive ameba, by microscopy, except in cases of invasive disease, where E. histolytica trophozoite may contain ingested red blood cells, but such a finding is rarely seen...

Mammalian epithelial, endothelial and various other cell types, upon their detachment from the extracellular matrix (ECM) undergo a specialized kind of apoptosis, known as anoikis. Entameba histolytica cysteine proteases have been implicated in degradation of the host ECM, which may induce anoikis in host cells. To explore this hypothesis, supernatant obtained from 2 h in-vitro cultivation of E. histolytica (SRP), was used as a source of cysteine proteases. MDA-MB-231 (human mammary epithelial adenocarcinoma) cells were treated with SRP and their detachment and apoptosis was evaluated...

Toxic megacolon represents a dreaded complication of mainly inflammatory or infectious conditions of the colon. It is most commonly associated with inflammatory bowel disease (IBD), i.e., ulcerative colitis or ileocolonic Crohn's disease. Lately, the epidemiology has shifted toward infectious causes, specifically due to an increase of Clostridium difficile-associated colitis possibly due to the extensive (ab)use of broad-spectrum antibiotics. Other important infectious etiologies include Salmonella, Shigella, Campylobacter, Cytomegalovirus (CMV), rotavirus, Aspergillus, and Entameba...

Acute appendicitis of amebic origin is considered a rare cause of acute appendicitis. We report a case of amebic appendicitis presenting with fever, severe pain in the right lower quadrant of the abdomen and rebound tenderness. Lab investigations revealed neutrophilic leukocytosis. The patient underwent appendectomy. Histopathological examination revealed numerous Entameba histolytica trophozoites in the mucosa of the appendix. Acute appendicitis of amebic origin does not appear frequently. Appendicular amebiasis can give the clinical features of acute appendicitis and should be treated accordingly...

The authors report a case of neonatal amebiasis presenting with vomiting, refusal to feeds, abdominal distension and mucoid stools. The diagnosis was made on the basis of clinical appearance of stools and the presence of Entameba Histolytica. The purpose of this report is to alert to the possibility of amoebiasis in newborns, if baby presents with NEC like picture in an endemic area and to send the stool sample immediately to examine for trophozoites, especially because the diarrheal stool starts autolyzing within 30 min of defecation...

The aim was to evaluate the efficacy of Saccharomyces boulardii (Sb) in addition to metronidazole in amebiasis. A prospective, randomized, open clinical trial was performed in 50 children presenting with acute bloody diarrhea caused by Entameba histolytica. Group A and B (each N = 25) was treated with metronidazole, but Sb (250 mg, twice daily) during the 7 days was added to Group B patients who were re-evaluated 2, 3, 5, 10, and 30 days after diagnosis. Duration of bloody diarrhea was significantly longer in Group A (72...

We investigated 245 diarrheal stool specimens from HIV-positive subjects between January 2003 and December 2006 to determine the etiological role of coproparasites. Parasitic etiology was observed in 91 (37.1%) cases. Isospora belli (26.1%) was the most common parasite followed by Entameba histolytica/dispar (3.3%), Cryptosporidium spp. (2.9%), Giardia intestinalis (1.6%), and Strongyloides stercoralis (1.2%). Interesting trends of significant increase in the number of cases of I. belli and decline in Cryptosporidium spp...

Microscopic identification of Entameba histolytica in stool is insensitive to differentiate this pathogenic ameba from morphologically identical Entameba dispar. An enzyme-linked immunosorbent assay method was applied for diagnosing amebiasis by detection of E. histolytica antibody. A total of 258 sample sera were analyzed from five different groups including amebiasis patients, E. histolytica/E. dispar asymptomatic cyst carriers, patients clinically presumed to have intestinal and extra-intestinal amebiasis and healthy control...

Parasitic infestations in man may cause transient or permanent pulmonary lesions. The lesions occur during migration and evolution of the parasites, during parasitemia, or during the final habitat. These manifestations, though infrequent in Canadian medical practice, present difficulties in diagnosis. Life cycles, mode of entry, and migration of parasites in the human body are described and illustrative case histories presented. In this series, transient pulmonary changes were associated with Ascaris lumbricoides, Ankylostoma duodenale, filariasis, Giardia lamblia and Trichinella spiralis; permanent lesions were produced by Entameba histolytica and Tenia echinococcus...

Pleuropulmonary amebiasis may be manifest without diarrhea or dysentery.In obscure lesions of the right lower lung field, one should always consider pleuropulmonary amebiasis-especially with low grade fever and moderate leukocytosis. Abscess and empyema contents should be examined promptly microscopically or kept warm to preserve the motility of the trophozoites until satisfactory examination is possible. Conservative therapy will successfully manage most cases of pleuropulmonary amebiasis. If a thorough search fails to reveal Entameba histolytica, and the diagnosis is still entertained, a medical therapeutic trial is in order...

An approximately 11-mo-old female giant anteater (Myrmecophaga tridactyla) exhibited anorexia, lethargy, hypothermia, depression, and minimal response to external stimuli. Radiography and ultrasonography revealed an enlarged heart, with free gas and fluid in the abdomen. Abdominocentesis produced a clear brown fluid with an acute to subacute septic suppurative exudate. Cardiac ultrasonography revealed a dilated, thin-walled left ventricle with a comparatively low fractional shortening. Despite intensive supportive care, the anteater died...
