Results of a survey to detect the mosquito Aedes albopictus in the French Riviera.

A programme of surveillance was initiated in 1992, in the French Riviera, to detect a possible introduction of Aedes albopictus from Italy and to prevent nuisances caused by mosquitoes in the touristic localities of the Côte d'Azur. In five years, numerous mosquito breeding places have been located. Nine species have been collected: Anopheles claviger, An. plumbeus, Aedes geniculatus, Ae. vittatus, Culex hortensis, Cx. impudicus, Cx. pipiens, Culiseta fumipennis, Cs. longiareolata but no Ae. albopictus was found. Nuisances were mainly due to hypogean populations of Cx. pipiens. Breeding places in urban sites have been controlled or suppressed. The discovery of an important larval population of An. plumbeus in an urban area might further stress the importance of this species already suspected to transmit indigenous malaria in cities.

Leishmaniasis in AIDS patients: results of leukocytoconcentration, a fast biological method of diagnosis.

Leukocytoconcentration is an easy, fast and inexpensive technique for the diagnosis of leishmaniasis from peripheral blood. The technique involves concentration of blood parasites on a small surface of a microscope slide while the red blood cells are removed by lysis. The results, compared with those of other methods (examination of cultures of blood samples and bone marrow smears), were very good and accurate. All but one of our cases of leishmaniasis were patients with HIV co-infection. Leukocytoconcentration facilitates follow-up of cases and fast detection of any relapse.

[Plasmodium vivax malaria seizure more than 5 years after a stay in Meknès (Morocco)].

The authors report a case of Plasmodium vivax malaria which happened more than five years after a stay of the patient in Morocco. The late appearance of parasite blood forms and especially gametocytes, as observed in this case, could explain, at least partially, the awakening of apparently extinguished foci and the renewal of the transmission of the epidemic, mediated by the presence of Anopheles. This phenomenon certainly contributed to the failure of malaria eradication campaigns in some countries with endemic P. vivax.

[Phlebotomus perniciosus Newstead, 1911 naturally infected by promastigotes in the region of Nice (France)].

The authors report the results of investigations in Nice from July, 16 to August, 3, 1991. The 2,098 phlebotomes captured represent three species: Phlebotomus perniciosus, Phlebotomus ariasi and Sergentomyia minuta. Two species: P. perniciosus and P. ariasi are infected with promastigotes. About 4% of dissected females are parasited. This is the first description in France of P. perniciosus infected.

[Indoor and outdoor nebulization of DDT in the campaign against cutaneous zoonotic leishmaniasis in Algeria].

Zoonotic cutaneous leishmaniasis is expanding in certain regions of Algeria. Since 1981, when the disease was confined to the foci of Biskra and Abadla, it spread to the neighbouring departments (wilayas) and especially to the wilaya of M'sila. The authors report the results of a large campaign against the disease, using DDT house spraying, in this wilaya. The annual incidence, which was 426 cases per 100,000 inhabitants in January 1983, dropped to 17.9 in January 1984. In addition, the efficacy of DDT in the reduction of the sandfly population was tested in two localities. One was sprayed with DDT and the other was not. In the sprayed locality the sandfly population decreased markedly as compared to the control locality. From these observations the authors believe that DDT plays a major role in the interruption of transmission, a hypothesis which needs to be confirmed by case-control studies. They further recommend that an interdisciplinary approach should be developed for the control of cutaneous leishmaniasis.

[Presence of Leishmania major MON-26 in Mali].

The arabo-african zymodem MON-26 was identified for the first time in an autochtonous patient from Mali. L. major has been previously identified in this country but it was in European patient and it was zymodem MON-25.

[Malarial problems and the trans-Saharan highway].

In Maghreb, malaria eradication is near. In particular, no indigenous strains of P. falciparum have been found for ten years. The few remaining cases of malaria are of P. vivax. In the Sahelian area, on the other hand, malaria eradication failed with P. falciparum and the efficient vector A. gambiae (s.l.). Until now, the Sahara desert separated these two areas. With construction of a trans-saharan highway, the situation is very different. Now, tropical malaria circulates in Maghreb and Sahara oases in the same way as vectors. However, it seems that local vectors in Maghreb (A. labranchiae) and in Sahara (A. multicolor et A. sergenti) are not efficient vectors for tropical strain of P. falciparum. These observations must be confirmed because there are probably different anopheles populations with different vectorial capacity in the same anopheles species and different plasmodial strains with different infective capacity in the same plasmodial species. Meanwhile a dangerous potential situation exists, the temporary or permanent colonization of some stations in Sahara, in Maghreb (?) by A. gambiae the efficient vector of tropical strains of P. falciparum. From now on, important efforts of Prevention and Control for vectors and malaria must be developed with large intensity in Saharan oases and in Maghreb.
