Disease relevance of Indian Ocean Islands

• A randomized controlled trial comparing the efficacy of pyrantel-oxantel (10 mg/kg) with mebendazole (500 mg) was performed on 1329 schoolchildren aged 6-9 years on Pemba Island in September-October 2000 to evaluate alternative single-dose drugs for regular treatment of intestinal nematode infections [1].

High impact information on Indian Ocean Islands

• The Maldives isolates hybridized with the DNA probe for the gene encoding the thermostable direct hemolysin (the tdh gene) under reduced stringencies [2].
• However, ED(50) values for strains isolated from Mafia island, an area never exposed to BZ treatment were lower than for Pemba, suggesting lowered sensitivity of hookworm eggs recovered from Pembian children towards BZ [3].
• In the perennially-flowing Pemba River, relatively small numbers of snails were collected; they were found only during the hot dry season (December to March) [4].
• Cribrostatin 6, a dark blue cancer cell growth inhibiting (P388 ED(50) 0.3 microg/mL) constituent of the Republic of Maldives marine sponge Cribrochalina sp., has been assigned structure 3 on the basis of a combination of HRMS, high-field (500 MHz, HMBC, and GOESY experiments) (15)N, (1)H, and (13)C NMR, and X-ray crystal structure analyses [5].
• The data on outcome were used for comparison with those from recent studies of similar treatment regimens in the neighbouring island of Pemba, Zanzibar, where periodic chemotherapy with mebendazole to schoolchildren has been implemented as part of a helminth-control programme since 1994 [6].

Anatomical context of Indian Ocean Islands

• For certification, 12 laboratories determined the number of cfp on two agars: Mannitol Egg-Yolk Polymyxin agar (MEYP, incubated at 30 degrees C) and Polymyxin pyruvate Egg-yolk Bromothymol blue Agar (PEMBA, incubated at 37 degrees C) [7].

Associations of Indian Ocean Islands with chemical compounds

• The risk of chloroquine resistance (already described in Tanzania) and the fact that only chloroquine is available on the island of Pemba, were the reasons for increasing the usual dose [8].
• The intestinal parasites of the schoolchildren from one rural area and one urban area, both on Pemba Island, Zanzibar, Tanzania, were surveyed within the framework of the local Helminth Control Programme. Stool samples were examined for helminth eggs and protozoa by quantitative (Kato-Katz) and concentration (formalin-ether) techniques [9].
