[Alteromonas putrefaciens. 25 strains isolated in Madagascar].

25 strains of Alteromonas putrefaciens, most of them from marine medium, isolated in Madagascar, are reported. Biochemical characters are studied to class them in 2 subspecies. Routinely, Alteromonas putrefaciens must be chiefly differentiate with H2S-producing Enterobacteriaceae. The ecology is recapitulated.

[The transmission of maternal measles antibodies to newborn infants in the Ivory Coast].

Authors studied the disappearance of mothers measles antibodies among 286 babies from Ivory Coast 250 of which were living in Adzopé, a town with 30,000 inhabitants at 100 km up North from Abidjan and the 36 other babies in Abidjan. The study of antibodies by IHA showed a higher serum incidence rate of mother antibodies among 4 months aged babies in Abidjan. The more sensitive study of antibodies by the Mann serum neutralisation, shows that when 6 months aged, 60% babies from Adzope still have antibodies and when 10 months aged, none of the babies is positive. Serum negativation is late compared to Brazzaville when antibodies level is lower.

[Arbovirus diseases in South America and Caribbean Islands (author's transl)].

Historically, yellow fever has dominated arboviral diseases in South America and the Caribbean and sylvatic cases still occur every year (more than 200 in 1979). The dengue, by the very large number of cases occurring in the area during successive epidemics--the most important being the last one in 1977-1978--is a serious problem for public health, an epidemic of hemorrhagic dengue being a constant threat. Encephalitides are the third syndrome of arboviral etiology observed in the South American subcontinent. Some which preferably attack horses have been known for a long time whereas the one due to the Rocio virus of an even graver prognosis, was recently discovered. These diseases present a large range of epidemiological forms. Dengue is an example of an urban illness transmitted from man to man through the mosquito, Aedes aegypti. But most of the viruses circulate between vectors and wild vertebrates in sylvatic cycle. For some viruses, both mechanisms can be involved. It is the case for Oropouche virus and yellow fever even if at present the urban form is the only recorded for the latter.

[Epidemic of yellow fever in the southeastern region of Upper Volta (October-December, 1983). Epidemiological study. Preliminary results].

An epidemic of yellow fever raged during the last three months of 1983 in South East of Upper Volta. It spread on about ten thousand square kilometers, in a bushy savanna area, affecting only populations living in contact with forest galleries, belonging especially to the peul ethnical group. The transmission of the virus was effected by sylvatic vectors, essentially Aedes furcifer. Serological tests showed that about 50 % of the population living in contact with forest galleries was affected, that is to say 15.000 to 17.500 people. The average death rate on the whole area was 4 % (800 to 1.700 deaths); the lethality rate was estimated between 6 and 10 % of affected people. On the whole, 54 strains of yellow fever virus were isolated from human blood samples, and 26 strains from batches of mosquitoes. We called this epidemic "intermediate sylvatic epidemic". The epidemic quickly decreased in the sylvatic area, owing to climatic conditions. A mass campaign of vaccinations prevented it from spreading to near urban centres. On this particular case, the thermostability on field of the vaccine 17D provided by the Institute Pasteur of Dakar was proved to be effective.
