| wash resistance and residual efficacy of long-lasting polyester netting coated with alpha-cypermethrin (interceptor) against malaria-transmitting mosquitoes in assam, northeast india. | malaria is endemic in assam, northeast india, with low-to-moderate transmission of the causative parasites, mostly by anopheles minimus. plasmodium falciparum is the predominant parasite (>60%), with remaining cases being due to p. vivax. as an alternative intervention for malaria control, long-lasting insecticidal nets [interceptor coated with alpha-cypermethrin 10% suspension concentrate (sc), 0.667% w/w, 0.2g/m(2)] underwent field evaluation for laboratory wash resistance and residual efficac ... | 2010 | 19762058 |
| malaria situation in forest-fringed villages of sonitpur district (assam), india bordering arunachal pradesh during an outbreak. | epidemiological and entomological studies were undertaken in forest-fringed villages in sonitpur district (assam) bordering arunachal pradesh, india to assess the malaria situation. blood smears (thick and thin) were collected from the fever cases through door-to-door survey. both the blood smears stained with giemsa were used for malaria parasite detection. slide positivity rate (spr) was recorded as 39.1% with predominance of plasmodium falciparum (97.1%) infections. children between 5 and 14 ... | 2007 | 17896624 |
| molecular characterization and species identification of the anopheles dirus and an. minimus complexes in north-east india using r-dna its-2. | the sibling species composition of the anopheles minimus and anopheles dirus complexes is poorly known in the highly malarious north-eastern region of india where these two vector taxa are accountable for most of the malaria transmission among 30.7 million inhabitants. prevalent members of these two complexes in this part of india were identified using sequences for the second internal transcribed spacer (its2) of ribosomal dna. anopheles baimaii (species d) of the an. dirus complex and an. mini ... | 2006 | 17118324 |
| physiographic and entomologic risk factors of malaria in assam, india. | fever surveys were conducted in several districts of the indian state of assam to ascertain the prevalence of malaria in relation to vector abundance, entomologic inoculation rates (eirs), and geographic location of human settlements. anopheles minimus were incriminated, but their relative abundance and biting rates varied among districts, and no significant correlation was observed between these two indicators (r = 0.43, p = 0.34). plasmodium falciparum was the predominant parasite species exce ... | 2004 | 15516642 |
