While colonic and hepatic amoebiasis occur commonly in tropical countries, primary pulmonary amoebiasis remains a rare condition. Pulmonary involvement, when it occurs, is usually secondary to amoebic liver abscess. Primary pulmonary amoebiasis is thought to occur via haematogenous spread. We report a case of primary pulmonary amoebiasis confirmed by visualizing the trophozoites of entamoeba hi...

Two ayurvedic preparations Arogya Vardhini Bati (AVB) and Anand Bhairava Ras (ABR) were found to cure intestinal amoebiasis of rat and hepatic amoebiasis of golden hamster. Both AVB and ABR were found to be amoebicidal against trophozoites of Entamoeba histolytic at 500 μg/ml in vitro and cured caecal amoebiasis of rat at 200 mg/kg/dose/5 dyas, in vivo.

Optimal conditions for carrying out the indirect haemagglutination test with sheep erythrocytes were studied using the microtitre system. The age of the erythrocytes, concentration of reagents, time and temperature of tanning, sensitization, and incubation are described with reference to replication of titres. Sera from patients with amoebic colitis were used to evaluate the test conditions.

The causative agent of amoebiasis is currently attributed to two distinct species (E. histolytica and E. dispar). The aim of this study was to differentiate these species by PCR in stool samples. Isolated genomic DNA was amplified by PCR and band products of 101 bp (E. dispar) were obtained. All seven stool samples were found to be E. dispar, not E. histolytica. Our results demonstrated the sig...

Pulmonary amoebiasis without liver involvement occurs sporadically as a result of haematogenous spread from a primary site, the colon. The case history is presented of a patient who developed superior vena cava syndrome due to a pulmonary amoebic abscess without liver involvement. He was initially suspected of having a neoplasm but a combination of tests including histological examination of th...

Serological test based on IHA (Indirect Haemagglutination Method) was performed in 100 cases of hepatic abscess. The test was 100% sensitive and 94% specific. The cut off point of antibody titer between normal population and patients with invasive amoebiasis was 1:128. Antibody titer in amoebic liver abscess was 1:5242 +/- 2795. A significant (P less than 0.001) correlation was found between to...

Amoebiasis is a problem in northern India. In Ayurveda several herbal drugs are mentioned, to be used for controlling the amatisara (amoebiasis) but none of the drug are found having potent effect to iradicate the disease. In ancient literature kutaj (Holarrhena antidysentrica) is mentioned in commonest was for controlling the disease this plant is prevalently found in Himalayan and vindhaya ar...
