| [leptospirosis on the island of reunion. iii. epidemiologic study]. | in the island of reunion, rodents and wild dogs can be carriers of leptospires. aquatic environmental plays an important part. human contamination is associated with water and sugar cane. animals are infected by numerous serogroups. | 1983 | 6671268 |
| [leptospirosis on the island of reunion. i. human leptospiroses]. | human leptospiroses in the island of reunion have a common point: they are severe diseases. approximately 50 to 60 cases are biologically diagnosed every year. the number of cases is correlated with rainfall. the predominating serogroup is icterohaemorrhagiae, followed by canicola, grippotyphosa and australis. | 1983 | 6671266 |
| forfeiture of proceeds of drug-related crimes: a british commonwealth perspective. | the forfeiture of the proceeds of drug-related offences does not seem to have received much attention as yet from british commonwealth countries. whereas in some of these countries specific legislation exists in relation to forfeiture, in many other countries the act of forfeiture falls within the purview of general criminal law. forfeiture presupposes enquiry and search, two procedures which involve integral aspects of present-day human rights law, and which seem to be impeded at almost every s ... | 1983 | 6556074 |
| [rift valley fever and zinga virus: a pathogenic arbovirus in man and animal new for madagascar]. | virus zinga strains have been isolated from several pools of mosquitoes collected in perinet area, 130 km far from tananarive, at the institut pasteur of madagascar in 1980. although this virus is pathogenic for man, it seemed to give only a mild illness and did not appear to constitute a problem of public health. but today it is seen in quite a different way; since the who center for arbovirus reference and research of new haven has shown the serologic identity between virus zinga and an anothe ... | 1984 | 6534285 |

| arboviruses and lemurs in madagascar: a preliminary note. | the epidemiological role played by lemurs in the circulation of arboviruses in madagascar has been studied. from serological (hai) tests, exposure of lemurs to alphaviruses and flaviviruses appears to vary considerably with location and species of lemur; positive tests varied from 0 to 32%. finally, the data concerning the lemurophilic part of the mosquito fauna suggests that some lemur species and man are infected by the same arboviruses, especially west nile virus. the susceptibility of these ... | 1982 | 6125046 |

| entomological aspects of filariasis control in sri lanka. | historical events and suitable environmental conditions in the southwestern coastal areas of sri lanka have led to the establishment of a zone of endemic filariasis caused by wuchereria bancrofti and transmitted by culex pipiens fatigans. the previous brugia malayi foci, scattered over widely dispersed areas of the island, were apparently completely eliminated as a result of control of the mansonia vectors by the destruction of the larval host plants in their swamp habitats. control measures by ... | 1974 | 4619057 |
