Comparison of multiplex-PCR and antigen detection for differential diagnosis of Entamoeba histolytica BJID
Santos,Helena Lúcia Carneiro; Peralta,Regina Helena Saramago; Macedo,Heloisa Werneck de; Barreto,Magali Gonçalves Muniz; Peralta,José Mauro.
Amebiasis is an infection caused by Entamoeba histolytica. However, differentiation between E. histolytica and Entamoeba dispar, which are morphologically identical species, is essential for treatment decision, precaution of the invasive disease and public health. The purpose of the present study was to evaluate a Multiplex -PCR for detection and differentiation of E. histolytica from E. dispar from fresh stool samples in comparison with the coproantigen commercial ELISA. Microscopic examination of stools using the Coprotest method, detection of stool antigen by enzyme-linked immunosorbent assay kit and a home made Multiplex-PCR, were used for the diagnosis of amoebiasis infection. Analysis of the 127 stools samples by microscopy examination demonstrated...

Hepatic amebiasis BJID
Salles,José Maria; Moraes,Luis Alberto; Salles,Mauro Costa.
Amebiasis can be considered the most aggressive disease of the human intestine, responsible in its invasive form for clinical syndromes, ranging from the classic dysentery of acute colitis to extra-intestinal disease, with emphasis on hepatic amebiasis, unsuitably named amebic liver abscess. Found worldwide, with a high incidence in India, tropical regions of Africa, Mexico and other areas of Central America, it has been frequently reported in Amazonia. The trophozoite reaches the liver through the portal system, provoking enzymatic focal necrosis of hepatocytes and multiple micro-abscesses that coalesce to develop a single lesion whose central cavity contains a homogeneous thick liquid, with typically reddish brown and yellow color similar to "anchovy...

Hepato-pulmonary amebiasis: a case report BJID
Shenoy,Vishnu Prasad; Vishwanath,Shashidhar; Indira,Bairy; Rodrigues,G.
Infections with Entamoeba histolytica are seen worldwide and are more prevalent in the tropics. About 90% of infections are asymptomatic, and the remaining 10% produce a spectrum of clinical syndromes, ranging from dysentery to abscesses of the liver or other organs. Extra-intestinal infection by E. histolytica most often involves liver. Pleuro-pulmonary involvement, seen as the second most common extra-intestinal pattern of infection, is frequently associated with amebic liver abscess. Pulmonary amebiasis occurs in about 2-3% of patients with invasive amebiasis. We report herein the case of a 45-year-old male presenting with hepato-pulmonary amebiasis. The diagnosis was established from direct examination of sputum, in which trophozoites of E. histolytica...

Infecção natural por Entamoeba histolytica Schaudinn, 1903 em Euphractus sexcinctus (tatu) mantidos em cativeiro Arq. Bras. Med. Vet. Zootec.
Soares,C.A.; Oliveira,J.B.; Brito,M.D.C..
Fecal samples of two species of armadillos Euphractus sexcinctus (Xenarthra, Dasypodidae), kept in captivity were analysed by direct and sedimentation methods. Entamoeba histolytica Schaudinn, 1903 and E. coli Grassi, 1879 (Amoebida, Endamoebidae) cysts were observed, the former for the first time in armadillos. This parasitism is worthy of registration in the literature because of the possibility of transmission to the human being when these animals are kept in captivity.

Prevalence and characters of Entamoeba histolytica infection in Saudi infants and children admitted with diarrhea at 2 main hospitals at south Jeddah: a re-emerging serious infection with unusual presentation BJID
Hegazi,Moustafa Abdelaal; Patel,Tabarek Ahmed; El-Deek,Basem Salama.
In this study, Entamoeba histolytica had high prevalence and unusual presentation by affecting high proportion of infants under 1 year; severe clinical manifestations, and laboratory findings that were known to be usually encountered in invasive amebiasis as significant leukocytosis for age, neutrophilic leukocytosis for age, and positive C-reactive protein were found among more than 50% of admitted Saudi infants and children with E. histolytica infection in our locality. E. histolytica can be a re-emerging serious infection when it finds favorable environmental conditions and host factors which are mainly attributed to inadequate breastfeeding in this study. This may occur in any other area of the world with the same risk factors, so we must be ready to...

Validation and utilization of PCR for differential diagnosis and prevalence determination of Entamoeba histolytica/Entamoeba dispar in Salvador City, Brazil BJID
Santos,Fred Luciano Neves; Gonçalves,Marilda de Souza; Soares,Neci Matos.
Amoebiasis is an infection caused by Entamoeba histolytica and is a potential health risk in countries in which health barriers are inappropriate. Since the discovery of Entamoeba dispar, the prevalence of amoebiasis has been modified. OBJECTIVE: This study has standardized the PCR technique applied for the diagnosis of different species of the E. histolytica/E. dispar complex and has evaluated the prevalence of infection among patients attending private and public clinical laboratories in Salvador City, Bahia State, Brazil. RESULTS: Analysis of 52,704 stool samples by microscopic examination demonstrated that 1,788 (3.4%) were positive for the E. histolytica/E. dispar complex and infection occurred more often in samples originated from public clinical...
