Immunocompromised patients with human immunodeficiency virus (HIV) infection are prone to multiple infections, of which parasitic infections are an important cause. Parasitic protozoal infections - both by common and rare protozoa are documented in such patients. Here, we report a rare and interesting case of five protozoal infections affecting a single HIV-infected person at the same time of initial presentation. A 64-years-male came to us with complaints of chronic diarrhea for 6 months. He was investigated and found to be positive for HIV I...

Entamoeba histolytica is one of the major pathogenic intestinal parasites and is amongst the leading causes of diarrheal illness in children. Around 500 million people are infected worldwide, while 75,000 die of the disease annually. E. histolytica is associated with moderate to severe diarrhoea and increased mortality among children in African countries and negatively affects child growth and development. Malnutrition is also an important contributor to the prevalence of E. histolytica in Ethiopia. It is mostly associated with poor hygiene, poverty, illiteracy, lack of access to potable water, and a hot, humid tropical climate...

The lysine and glutamic acid rich protein KERP1 is a cell surface-expressed virulence factor in the human pathogen Entamoeba histolytica. It was originally suggested that the gene was absent from the related, avirulent human commensal Entamoeba dispar, an absence which would be relevant to the differential virulence of these species. Here, the gene is shown to be present in E. dispar, and its sequence is presented, as well as in a virulent parasite of macaques, Entamoeba nuttalli, and the primarily free living, opportunistically parasitic Entameba moshkovskii...

OBJECTIVES: Gastrointestinal complications are common in kidney transplant patients, with the most frequent being diarrhea (60%). Chronic diarrhea affects the patient's quality of life, causes fatigue and weight loss and malabsorption, increases the number of hospitalizations, increases serum creatinine levels, and causes alterations in immunosuppressive drug levels. Diarrhea is also associated with an increased risk of graft failure and death. In this study, we aimed to determine the frequencies of common infectious organisms causing chronic diarrhea in renal transplant patients...

OBJECTIVE: The aim of this cross-sectional study was to determine the magnitude of intestinal parasitosis and anaemia in a Health Center, North Ethiopia. RESULTS: A total of 427 outpatients were enrolled and the median age of the participants was 22 years. The prevalence of intestinal parasitosis was 143 (33.5%). Age, place of residence and occupation were significantly associated with intestinal parasitosis. When we see parasite specific factors, significant associations were observed for source of drinking water (P = 0...

Yemen is a developing country overwhelmed with a triad of poverty, diseases and social conflicts. Moreover, the majority of its population live in rural communities and suffer from intestinal parasitic infections (IPIs). Therefore, the present school-based, cross-sectional survey aimed to detect the prevalence of such infections and associated risk factors among schoolchildren in the rural communities of Bani Alharith, Hamdan and Bani Hushaysh districts of Sana'a, north of Yemen. Socio-demographic data and certain behavioral risk factors as well as stool samples were collected from 1218 schoolchildren from ten randomly schools in the study area...

CONTEXT: Parasitic opportunistic infections (POIs) frequently occur in HIV/AIDS patients and affect the quality of life. AIMS: This study assessing the standard organisms in the stool of HIV-positive patients, their comparison with HIV-negative controls, their relation with various factors, is the first of its kind in the eastern part of India. SETTINGS AND DESIGN: hospital-based case-control study. MATERIALS AND METHODS: A total of 194 antiretroviral therapy naïve HIV-positive patients (18-60 years) were taken as cases and 98 age- and sex-matched HIV-negative family members as controls...

Parasitoses are the commonest health problem among school age clildren, which impair children's growth and development and causing anemia. To detect the role of parasitic infections and both anemia and growth affection, on one hand, and if so the common complications among males and females on the other hand, a cross sectional descriptive study was carried out among the outpatient attended the Pediatrics Clinic, Al-Fayoum University's Hospitals. A total of 314 children aged from 1 to 13 years were subjected to clinical examination as well as stool analysis and CBC examination...

Blood cultures were drawn from all patients in the first 24 hours after admission. In addition, all patients had stool examinations and indirect Hemagglutination test for Entameba histolytica...

BACKGROUND: Intestinal amebiasis is an important public health problem worldwide. More severe disease is associated with young age, malnutrition and immunosuppression. AIM: The aim of this study is to evaluate the prevalence and characteristic nature of intestinal amebiasis among pediatric population, and compare it with other causes of gastroenteritis. MATERIALS AND METHODS: This is a retrospective comparative study conducted at Makassed General Hospital between January 2008 and December 2012, including all pediatric patients between birth and 15 years of age, who presented with symptoms of acute gastroenteritis...

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...

Kidney transplant recipients are susceptible to various infections due to the use of immunosuppressive drugs. The present study was performed as studies on the prevalence of intestinal fungal and parasitic infections in kidney transplant recipients are limited. A total of 150 kidney transplant recipients and 225 matched immunocompetent outpatients, who were referred to the laboratory of Noor Hospital, Isfahan, were studied. After recording demographic characteristics, direct test and specific laboratory cultures were carried out on the stool specimens...

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...
