Isolation of Entamoeba histolytica from arthritic knee joint.

Amoebae were isolated from an arthritic knee of a male patient. The organisms grew in Egg Yolk Infusion medium, and in Diamond's Biosate Iron-Serum-33 medium, which contained Trypanosoma cruzi, and were identified microscopically as Entamoeba histolytica. Furthermore, amoebae-like organisms in aspirate and cultures were immunocytochemically identified using monoclonal antibodies against E.

The impact of three-monthly age-targetted chemotherapy on Ascaris lumbricoides infection.

The impact of 3 chemotherapeutic regimens at 3-monthly intervals against Ascaris lumbricoides infection, targetted at under 15 years old children with and without initial mass chemotherapy, and at 2-12 years old children, was studied in three Myanmar [Burmese] rural communities over a period of 2 years. Computation was made of prevalence and intensity (worm burden) of Ascaris infection, and other parameters for estimation of basic reproductive rate (R0) of the parasite and of the proportion of target age group to be treated 3-monthly (g) by employing the mathematical model for targetted chemotherapy. The 3 treatment regimens were almost equally effective in reducing prevalence and intensity in both the targetted and non-targetted age groups.

A controlled chemotherapeutic intervention trial on the relationship between Ascaris lumbricoides infection and malnutrition in children.

A 2-year investigation, consisting of a controlled, non-blind, 3-monthly chemotherapeutic intervention trial, based on transmission dynamics of Ascaris lumbricoides infection, was undertaken to prove or refute the role of A. lumbricoides as a contributor to childhood malnutrition. The study involved 1206 children aged 2-12 years in 21 villages in Myanmar [Burma] starting in August 1984.

Control of ascariasis through age-targeted chemotherapy: impact of 6-monthly chemotherapeutic regimens.

A field trial of 6-monthly ascariasis chemotherapeutic regimens targeted at 1-19-, 1-14-, and 5-19-year-olds was carried out in three communities in rural Myanmar to observe the effects on the prevalence, intensity, and morbidity indicators over 2 years. After periodic chemotherapy, the prevalence and intensity of Ascaris infection in age-targeted and non-age-targeted groups fell in all the study areas, more markedly among the 1-19- and 1-14-year-olds. There was also a decrease in the frequency of vomiting of worms, passing of worms per anus, coughing, abdominal pain and treatment of bowel complaints, especially among the treated groups.

Epidemiology and transmission dynamics of Ascaris lumbricoides in Okpo village, rural Burma.

A horizontal study of the prevalence of Ascaris infection was carried out on the total population of Okpo village near Rangoon, Burma, where a similar study had been conducted 13 years earlier. Ascaris eggs in faeces were counted after treatment with levamisole on a random sample of 50% of the infected population to give information to the numbers of epg of stool, the mean worm burden per host and the distribution of worms in the community. The information on prevalence is compared with that of the previous survey.
