BACKGROUND & OBJECTIVES In the present study, an attempt was made to find reasons of ineffectiveness of indoor residual spray to interrupt malaria transmission by investigating the behaviour of two variants of Anopheles stepnesi, viz. type form and mysorensis in rural areas of Rajasthan, India. METHODS Both low malarious (DDT spray from 1958 to 1976) and high malarious (DDT spray from 1958 to...

BACKGROUND Carboxy-terminal 42 kDa region of Plasmodium vivax merozoite surface protein-1 is considered as an important antigen in blood stage. Since, this region has been observed to be polymorphic among isolates of P. vivax, it is significant to survey on different regions of this antigen in various areas of the world. METHODS In the present study, the genetic diversity of cloned PvMSP-142 ...

OBJECTIVES To determine whether the re-introduction of DDT in KwaZulu-Natal had any effects on malaria transmission in the province. DESIGN, SETTING AND SUBJECTS The 2000 malaria epidemic in KwaZulu-Natal has been attributed to pyrethroid-resistant anopheles mosquitoes in the area. Previous studies have shown that these mosquitoes are still susceptible to DDT. To determine whether DDT re-intr...

In 1991, some 90 countries or areas where 42% of the world's population resided were considered malarious and estimation of malaria mortality worldwide per year was 1.5 to 3 million'). The Ministry of Justice reported that the total number of Japanese who went abroad was as many as 11,790, 699 and the number of foreigners who entered Japan for the first time was 3,251,753 in 1992. Consequently ...

Between 1981 and 1989, a total of 7683 cases of Plasmodium vivax [corrected] malaria were imported into the USSR from Afghanistan, mainly by demobilized military personnel. For 23.8% of these cases the clinical manifestations appeared within a month of returning to the USSR, for 22.5% after 1-3 months, for 20% after 4-6 months, for 2% after > 1 year, and for 0.6% after > 2 years. For 13 patient...

In northern California, western fence lizards, Sceloporus occidentalis, are frequently parasitized by Plasmodium mexicanum, which causes malaria. Animals with this naturally occurring malarial infection are anemic: immature erythrocytes in peripheral blood become abundant (1 to 30 percent), and blood hemoglobin concentration decreases 25 percent. Maximal oxygen consumption decreases 15 percent ...

We are glad to find that so many of our most active and scientific medical officers in this part of India are anxious to add to our stock of knowledge by means of carefully recorded facts regarding the action of quinine in cases of malarious fever. In the Indian Medical Gazette for December last, Dr. J. Butler Hamilton, e.a., recorded a case of ague showing the action of quinine as influencing ...

Geographical DistribuHon. BLACKWAfER fever is met with in intensely malarious districts, with high endemic indices Dinajpur district in North Bengal is specially mentioned by Sir Leonard Rogers in his book 011 " Fevers in the Tropics " as one of the districts with a notoriously high mortality; this obviously accounts for the occurrence of 'blackwater fever. During the 18 months I was in the dis...
