Malaria has always been a pernicious problem of serious health hazard in the northeast region of India. The problem is worst for military and paramilitary forces deputed in all the states of this part of country. The forces are deployed for a short time generally from non malarious regions and thus become highly vulnerable to acquire the malaria infection. Several potential malaria vectors with very high vectorial capacity and high slide positivity rate in civil population manifold the chances of infection. In the present review, the incidence of malaria in the armed forces and paramilitary forces are discussed in detail and minimal measures for the control of malaria in northeastern region have been suggested.Defence Science Journal, 2010, 60(2), pp.213-218, DOI:http://dx.doi.org/10.14429/dsj.60.342

This study was carried out to determine the human host preference and presence of Plasmodium parasite in field collected Anopheles mosquitoes among four villages around a military cantonment located in malaria endemic Sonitpur district of Assam, India. Encountered malaria vector mosquitoes were identified and tested for host preference and Plasmodium presence using PCR method. Human host preference was detected using simple PCR, whereas vectorial status for Plasmodium parasite was confirmed using first round PCR with genus specific primers and thereafter nested PCR with three Plasmodium species specific primers. Out of 1874 blood fed vector mosquitoes collected, 187 (10%) were processed for PCR, which revealed that 40.6% had fed on human blood; 9.2% of human blood fed mosquito were harbouring Plasmodium parasites, 71.4% of which were confirmed to Plasmodium falciparum. In addition to An. minimus, An. annularis and An. culicifacies were also found positive for malaria parasites. The present study exhibits the human feeding tendency of Anopheles vectors highlighting their malaria parasite transmission potential. The present study may serve as a model for understanding the human host preference of malaria vectors and detection of malaria parasite inside the anopheline vector mosquitoes in order to update their vectorial status for estimating the possible role of these mosquitoes in malaria transmission. The study has used PCR method and suggests that PCR-based method should be used in this entire malarious region to correctly report the vectorial position of different malaria vectors.
