Experimental infection of rhesus monkeys with Entamoeba histolytica mimics human infection.

Experimental infection of Entamoeba histolytica was successfully established in rhesus monkeys (Macaca mulatta). Parasites of proven pathogenicity maintained through liver passage in hamsters were used in this study. Laparotomized monkeys were inoculated intracecally/intrahepatically with trophozoites, or by oral administration of cysts (2000 cysts/ml). The cysts were isolated from an infected human stool sample. Formation of typical amebic lesions in the inoculated tissues along with alterations in hematologic indices were studied in the infected monkeys. All the experimentally inoculated monkeys showed leukocytosis and mild neutrophilia, while the hemoglobin content and levels of blood sugar and blood urea remained unaltered during the post-infection period. Specific antiamebic antibodies were readily detectable in post-infected sera.

Effect of mebendazole against Echinococcus granulosus and Taenia hydatigena cysts in naturally infected sheep and relevance to larval tapeworm infections in man.

The ability of three treatment schedules of mebendazole to kill well-established hydatid cysts was studied. Pregnant sheep, naturally infected with Echinococcus granulosus and/or Taenia hydatigena, were treated daily with mebendazole at a dose rate of 50 mg/kg body weight for either five days, one month, or three months. At autopsy, seven months after the commencement of treatment, no evidence was found that the 5-day treatment schedule had any damaging effect on E. granulosus cysts. The effects of the one month treatment were equivocal. There was evidence of a damaging effect from the 3-month treatment schedule and protoscoleces were not infective to dogs. No T. hydatigena cysts survived the 1- and 3-month treatments, but organisms from the 5-day treatment were infective to dogs. These results for E. granulosus in sheep suggest that long-term treatment with mebendazole may be required in hydatid disease in man. The results obtained for T. hydatigena in sheep are discussed in relation to the treatment of cysticercosis from T. solium in man. Mebendazole showed no untoward effect on the sheep or their lambs.

Acute rheumatic fever during childhood in Kuwait: the mild nature of the initial attack.

A prospective clinical study is reported of the initial attack of acute rheumatic fever in 210 children seen in Kuwait over a period of four years. The main presenting feature was pain in the joints, caused by arthritis in 79% of our patients and by arthralgia in 15%. Five per cent presented with chorea alone and 1% with congestive heart failure alone. Carditis was detected in 46.2%, cardiomegaly in 10%, pericarditis in 1.4% and congestive heart failure in 4.8%. The incidence of chorea was 7.6%, of erythema marginatum 1% and of subcutaneous nodules 0.5%. The mortality rate was 0.5%. Data from this study reflect the mild nature of acute rheumatic fever in Kuwait, in contrast to the aggressive nature of the disease described from neighbouring and developing countries.
