[Hematologic features in imported malaria. Value for the diagnosis of forms with low parasitemia].

Blood cell counts were performed on blood samples from 37 patients with imported malaria using three different blood analyzers (Coulter STKR, Coulter VCS and Technicon H1). Results were controlled by direct microscopic examination. Anemia, leukopenia, thrombocytopenia, or abnormalities of the leukocyte differential count were found in 32, 24, 30 and 92% of patients, respectively.

[Focus of borreliosis in Gisenyi (Rwanda)].

As a result of the increase of relapsing fever cases in a rural area of West-Rwanda, a study of ticks collected in the houses has been performed. Ornithodoros moubata specimens were found in large amount. In patients, fever is the most frequent symptom.

Detection with a monoclonal antibody of a polysaccharide antigen, excreted in the urine, in the schistosomiasis intercalatum focus of Edea (Cameroon).

The detection in the urine specimens of a sample of the inhabitants of Edea of a polysaccharide antigen characteristic for the genus Schistosoma, with monoclonal antibody by means of the inhibition of a passive haemagglutination test, shows that this technique is very sensitive for measuring prevalence of schistosomiasis due to S. intercalatum. In Edea, looking for eggs in stool specimens gives a low prevalence rate of the disease because of the low parasitic load.

[In vivo amodiaquine sensitivity of Plasmodium falciparum in the town of Cotonou and in the vicinity (Bénin)].

In the coastal area of Benin, where chloroquine resistant Plasmodium falciparum strains occur, 152 children in the Guezo military camp (Cotonou) and 448 children in a fishermen village (Ekpe), on the southern bank of lake Nokoue, are examined. The falciparum malaria infected children (29 and 135 respectively) have received 35 mg/kg body weight of amodiaquine (Flavoquine) divided in three consecutive daily doses. Only one child among the 69 treated having a parasitemia higher than 1,000/mm3 failed to be cured.
