The potential of house fly, Musca domestica (L) in the mechanical transmission of influenza A subtype H1N1 virus under laboratory conditions

Wasi Ahmad Nazni, Maguy Eugène, A H Azahari, Mohd Khadri Shahar et autres

A study on house flies was carried out to establish whether house flies can transmit the H1N1 virus mechanically due to their abundance, ability to transport pathogens and their behavioral traits of regurgitation and defecation. The objectives of this study were to …

DNA barcoding complementing morphological taxonomic identification of mosquitoes in peninsular Malaysia: A Noor Afizah, MM Torno, J Nur Jannah, AH Azahari, M Khairul Asuad, WA Nazni, HL Lee

A. N. Afizah, M. M. Torno, J. N. Jannah, A H Azahari et autres

Morphology-based mosquito identification is a gold standard, which is inexpensive and requires minimal tools and/or equipment. Nonetheless, it re-quires a high level of expertise and misdiagnosis is common. In addition, quality of samples is not always sufficient for identification at the species …

Single and co-breeding of different mosquito species in fogging-free and dengue risk areas in West Malaysia.
