Performance of MALDI-TOF Mass Spectrometry to Determine the Sex of Mosquitoes and Identify Specific Colonies from French Polynesia
Am J Trop Med Hyg. 2021 Mar 22:tpmd200031. doi: 10.4269/ajtmh.20-0031. Online ahead of print.ABSTRACTMosquitoes are the main arthropod vectors of infectious diseases in humans. The current methods for mosquito identification include morphological and molecular methods. Matrix-assisted laser desorption/ionization time-of-flight mass spectrometry (MALDI-TOF MS), now routinely used for bacterial identification, has recently emerged in the field of entomology. The aim of this study was to use MALDI-TOF MS to identify mosquito colonies from French Polynesia. Five hundred specimens from French Polynesia belonging to three specie...

Spatial and Temporal Patterns of Malaria in Phu Yen Province, Vietnam, from 2005 to 2016.
This study aimed to assess correlations between intervention (population proportion protected by insecticide-treated nets and indoor residual spraying) and climatic variables with malaria incidence in Phu Yen Province. The Vietnam National Institute of Malariology, Parasitology, and Entomology provided incidence data for Plasmodium falciparum and Plasmodium vivax for 104 communes of Phu Yen Province from January 2005 to December 2016. A multivariable, zero-inflated Poisson regression model was developed with a conditional autoregressive prior structure to identify the underlying spatial structure of the data and quantify a...

Domestic Triatoma sanguisuga-Human Exposure in the South Carolina Coastal Region.
Abstract A collaborative investigation was initiated in rural coastal South Carolina in response to a reported triatomine bite. The eastern conenose bug, Triatoma sanguisuga, was identified and tested for Trypanosoma cruzi. The insect was negative by PCR, and no additional triatomines were found in the vicinity of the home. This is the first published report of a bite from T. sanguisuga in South Carolina despite the fact that triatomine vectors have been documented in the state since the 1850s, and specimens have been collected from homes in the past. Sylvatic T. cruzi reservoirs are common throughout the southeas...

A Revival of Epidemiological Entomology in Senegal.
Abstract The term epidemiological entomology was first coined by Garrett-Jones over half a century ago1 but has been out of fashion for far too long.2 In this issue, Sougoufara et al.3 illustrate clearly just how insightful such an approach can be when applied to characterizing key properties of a dynamic malaria transmission system before and after the scale-up of vector control with long-lasting insecticidal nets in Dielmo, Senegal. Using simple analytical models first pioneered by Garrett-Jones himself,4 these authors illustrate how not all may be as it appears based on direct interpretation of entomological da...

Falciparum Malaria Outbreak in Sabah Linked to an Immigrant Rubber Tapper.
In conclusion, an outbreak of P. falciparum malaria was introduced into a malaria-free village by a migrant rubber tapper, by whom the imported parasite was introduced to the community via vector Anopheles balabacensis. Living near stagnant water bodies was the risk factor in this outbreak. PMID: 29141714 [PubMed - as supplied by publisher]
