Status of imported malaria in a control zone of the United Arab Emirates bordering an area of unstable malaria.

A concerted malaria eradication programme in the United Arab Emirates has reduced local transmission to only a very few small foci in the country. The Al Ain district is now a consolidation zone. However, transmission across the undemarcated border with Oman continues. Malaria imported by the large immigrant work force from major disease endemic areas remains a large burden. An added threat is the appearance of chloroquine-resistant Plasmodium falciparum principally from Sudan and Pakistan but increasingly amongst Omani cases seen in the hospitals and clinics in Al Ain. The implications of re-introduction of malaria and the establishment of chloroquine resistance, particularly for non-immune residents and visitors, are emphasized.

Inhibition of rotavirus infection in vitro and in vivo by a synthetic peptide from VP4.

A synthetic peptide corresponding to bovine rotavirus C486 (BRV) VP4 amino acid sequence 232-255 (VP4-peptide) was studied with the objective of defining the origin of the protective immune response reported previously by Ijaz et al. (J. Virol. 1991, 65, 3106-3113). Pretreatment of MA-104 cells with the VP4-peptide before infection with rotavirus prevented both the attachment of 35S-labelled virus and plaque formation in vitro. In vivo studies using a murine rotavirus model demonstrated that intragastric administration of VP4-peptide protected subjects from challenge with virulent rotavirus. These results clearly indicate the importance of this epitope in virus-cell interactions and their potential as a rotavirus vaccine candidate.
