Investigating the blood-host plasticity and dispersal of Anopheles coluzzii using a novel field-based methodology.

Parasit Vectors 2019 Mar 25;12(1):143. Epub 2019 Mar 25.

Department of Disease Control, London School of Hygiene & Tropical Medicine, London, UK.

Background: The biting behaviour and dispersal of insect vectors in the field underlies the transmission of many diseases. Here, a novel collection methodology coupled with the molecular analysis of blood-meal sources and digestion rates is introduced with the aim of aiding the understanding of two critical and relatively understudied mosquito behaviours: plasticity in blood-host choice and vector dispersal.

Results: A collection strategy utilising a transect of mosquito traps placed at 50 m intervals allowed the collection of blood-fed Anopheles coluzzii from a malaria-endemic village of southern Ghana where human host availability ranged from zero (a cattle pen), increasing until humans were the dominant host choice (the middle of the village).

Mosquito electrocuting traps for directly measuring biting rates and host-preferences of Anopheles arabiensis and Anopheles funestus outdoors.

Malar J 2019 Mar 18;18(1):83. Epub 2019 Mar 18.

Environmental Health and Ecological Sciences Department, Ifakara Health Institute, Off Mlabani Passage, P.O. Box 53, Ifakara, Tanzania.

Background: Mosquito biting rates and host preferences are crucial determinants of human exposure to vector-borne diseases and the impact of vector control measures. The human landing catch (HLC) is a gold standard method for measuring human exposure to bites, but presents risks to participants by requiring some exposure to mosquito vectors. Mosquito electrocuting traps (METs) represent an exposure-free alternative to HLCs for measuring human exposure to malaria vectors. Read More

Feasibility of feeding Aedes aegypti mosquitoes on dengue virus-infected human volunteers for vector competence studies in Iquitos, Peru.

PLoS Negl Trop Dis 2019 02 12;13(2):e0007116. Epub 2019 Feb 12.

Department of Entomology and Nematology, University of California, Davis, Davis, California, United States of America.

Background: Transmission of dengue virus (DENV) from humans to mosquitoes represents a critical component of dengue epidemiology. Examinations of this process have generally been hampered by a lack of methods that adequately represent natural acquisition of DENV by mosquitoes from humans. In this study, we assessed artificial and natural blood feeding methods based on rates of DENV infection and dissemination within mosquitoes for use in a field-based epidemiological cohort study in Iquitos, Peru.

Acceptability of Aedes aegypti blood feeding on dengue virus-infected human volunteers for vector competence studies in Iquitos, Peru.

PLoS Negl Trop Dis 2019 02 11;13(2):e0007090. Epub 2019 Feb 11.

Global Community Health and Behavioral Sciences, Tulane University School of Public Health and Tropical Medicine, New Orleans, Louisiana, United States of America.

As part of a study to investigate drivers of dengue virus (DENV) transmission dynamics, this qualitative study explored whether DENV-infected residents of Iquitos, Peru, considered it acceptable (1) to participate in direct mosquito feeding experiments (lab-reared Aedes aegypti mosquitoes fed directly on human volunteers) and (2) to provide blood meals indirectly (Ae. aegypti fed on blood drawn from participants by venipuncture). Twelve focus group discussions (FGDs; 94 participants: 82 females and 12 males) were conducted in January 2014 to explore six themes: (1) concerns and preferences regarding direct mosquito feeds and blood draws, (2) comprehension of and misconceptions about study procedures, (3) motivating factors for participation, (4) acceptability of children's participation, (5) willingness to provide multiple samples over several days, and (6) preference for direct feedings in homes versus the study laboratory.

Venomous Bites, Stings, and Poisoning: An Update.

Authors:
David A Warrell

Infect Dis Clin North Am 2019 Mar;33(1):17-38

Nuffield Department of Clinical Medicine, University of Oxford, John Radcliffe Hospital, Headington, Oxford OX3 9DU, UK. Electronic address:

This article discusses the epidemiology, prevention, clinical features, and treatment of venomous bites by snakes, lizards, and spiders; stings by fish, jellyfish, echinoderms, insects, and scorpions; and poisoning by ingestion of fish, turtles, and shellfish. Invertebrate stings cause fatalities by anaphylaxis, secondary to acquired hypersensitivity (Hymenoptera, such as bees, wasps, and ants; and jellyfish), and by direct envenoming (scorpions, spiders, jellyfish, and echinoderms). Simple preventive techniques, such as wearing protective clothing, using a flashlight at night, and excluding venomous animals from sleeping quarters, are of paramount importance to reduce the risk of venomous bites and stings.

Entomological assessment of the transmission following recrudescence of onchocerciasis in the Comoé Valley, Burkina Faso.

Parasit Vectors 2019 Jan 15;12(1):34. Epub 2019 Jan 15.

Ministère de l'Enseignement Supérieur, de la Recherche Scientifique et de l'Innovation, Institut de Recherche en Sciences de la Santé (IRSS), Direction Régionale de l'Ouest, BP 545, Bobo Dioulasso 01, Burkina Faso.

Background: Onchocerciasis, or river blindness, is a dermal filariasis caused by infection with the nematode parasite Onchocerca volvulus, transmitted to humans through the bites of blackflies of the genus Simulium. Despite the decade-long West African Regional Programme for the Elimination of Onchocerciasis, involving the mass administration of ivermectin to populations in endemic areas, recrudescence has occurred. An example is in the Cascades Region of south-west Burkina Faso where the resumption of transmission had resulted in infection prevalences of up to 70% in some villages. Read More

Molecular evidence for the inhibition of cytochrome p450s and cholinesterases in ticks by the repellent DEET.

Ticks Tick Borne Dis 2019 04 2;10(3):515-522. Epub 2019 Jan 2.

Department of Biology, Brandon University, Brandon, MB R78 6A9, Canada. Electronic address:

For more than 50 years DEET (N,N-Diethyl-m-toluamide) has been considered the gold standard of repellents. It is applied to the skin or clothing to deter mosquitoes and other blood-sucking invertebrate pests from approaching and/or settling, and ultimately it provides temporary protection from bites. Despite rampant global use, surprisingly little is understood about DEET's mode of action and the molecular targets of the active ingredient. Read More

Host-feeding patterns of Culex mosquitoes in Iran.

Parasit Vectors 2018 Dec 27;11(1):669. Epub 2018 Dec 27.

Bernhard Nocht Institute for Tropical Medicine, WHO Collaborating Centre for Arbovirus and Hemorrhagic Fever Reference and Research, Hamburg, Germany.

Background: Different mosquito-borne pathogens are circulating in Iran including Sindbis virus, West Nile virus, filarioid worms and malaria parasites. However, the local transmission cycles of these pathogenic agents are poorly understood, especially because ecological data on vector species are scarce and there is limited knowledge about the host range; this understanding could help to direct species-specific vector control measurements or to prioritize research.

Methods: In the summers of 2015 and 2016, blood-fed mosquitoes were collected at 13 trapping sites on the coast of the Caspian Sea in northern Iran and at an additional trapping site in western Iran. Read More

Inferences about the transmission of lumpy skin disease virus between herds from outbreaks in Albania in 2016.

Prev Vet Med 2018 Dec 17. Epub 2018 Dec 17.

European Food Safety Authority, Via Carlo Magno 1A, 43126 Parma, Italy.

Lumpy skin disease has recently emerged as a major threat to cattle populations outside of Africa, where it is endemic. In 2015 the first ever European outbreaks occurred in Greece, which were followed by spread across much of the Balkans in 2016. Here we use a simple mathematical model for the transmission of lumpy skin disease virus (LSDV) between herds to explore factors influencing its spread by fitting it to data on outbreaks in Albania in 2016.

Screening of mosquitoes for filarioid helminths in urban areas in south western Poland-common patterns in European Setaria tundra xenomonitoring studies.

Parasitol Res 2019 Jan 8;118(1):127-138. Epub 2018 Dec 8.

Department of Influenza Research, National Influenza Center, National Institute of Public Health - National Institute of Hygiene, Chocimska 24, 00-791, Warszawa, Poland.

In recent years, numerous studies screening mosquitoes for filarioid helminths (xenomonitoring) have been performed in Europe. The entomological monitoring of filarial nematode infections in mosquitoes by molecular xenomonitoring might serve as the measure of the rate at which humans and animals expose mosquitoes to microfilariae and the rate at which animals and humans are exposed to the bites of the infected mosquitoes. We hypothesized that combining the data obtained from molecular xenomonitoring and phenological studies of mosquitoes in the urban environment would provide insights into the transmission risk of filarial diseases.

A Fatal Case of Acute Renal Failure From Envenoming Syndrome After Massive Bee Attack: A Case Report and Literature Review.

Authors:
Rhome L Hughes

Am J Forensic Med Pathol 2019 Mar;40(1):52-57

From the University of North Dakota School of Medicine and Health Sciences, Grand Forks, ND.

Envenoming syndrome is a systemic toxic reaction to the inoculation of large volume of insect venom, typically after a swarm attack from bees. Africanized honey bees are notorious for their aggressive nature, and human deaths resulting from Africanized honey bee attacks are consistently reported. Whereas anaphylaxis is the most common lethal mechanism of injury, delayed deaths can also occur as a consequence of severe venom toxicity with resultant end organ damage. Read More

Spatial-temporal heterogeneity in malaria receptivity is best estimated by vector biting rates in areas nearing elimination.

Parasit Vectors 2018 Nov 27;11(1):606. Epub 2018 Nov 27.

James Cook University, Australian Institute of Tropical Health and Medicine, Cairns, QLD, 4870, Australia.

Background: Decisions on when vector control can be withdrawn after malaria is eliminated depend on the receptivity or potential of an area to support vector populations. To guide malaria control and elimination programmes, the potential of biting rates, sporozoite rates, entomological inoculation rates and parity rates to estimate malaria receptivity and transmission were compared within and among geographically localised villages of active transmission in the Western Province of the Solomon Islands.

Results: Malaria transmission and transmission potential was heterogeneous in both time and space both among and within villages as defined by anopheline species composition and biting densities. Read More

Of Genes and Genomes: Mosquito Evolution and Diversity.

Trends Parasitol 2019 01 1;35(1):32-51. Epub 2018 Nov 1.

Department of Ecology and Evolution, University of Lausanne, 1015 Lausanne, Switzerland; Swiss Institute of Bioinformatics, 1015 Lausanne, Switzerland. Electronic address:

Mosquitoes are widely despised for their exasperating buzzing and irritating bites, and more poignantly because, during blood-feeding, females may transmit pathogens that cause devastating diseases. However, the ability to transmit such viruses, filarial worms, or malaria parasites varies greatly amongst the ∼3500 recognised mosquito species. Applying omics technologies to sample this diversity and explore the biology underlying these variations is bringing increasingly greater resolution that enhances our understanding of mosquito evolution.

Baseline entomologic data on malaria transmission in prelude to an indoor residual spraying intervention in the regions of Alibori and Donga, Northern Benin, West Africa.

Malar J 2018 Oct 29;17(1):392. Epub 2018 Oct 29.

Centre de Recherche entomologique de Cotonou (CREC), Cotonou, Benin.

Background: Despite the success of indoor residual insecticide spraying (IRS) in Africa, particularly in Benin, some gaps of information need to be filled to optimize the effectiveness of this intervention in the perspective of the country's effort to eliminate malaria. In anticipation to the 2018 IRS campaign in two targeted regions of northern Benin, this study aimed, to collect baseline information on vector composition, spatio-temporal variation and peak malaria transmission in the Alibori and Donga, two targeted regions of northern Benin. Information collected will help to better plan the implementation and later on the impact assessment of this IRS campaign. Read More

Study on the correlation between age and changes in mosquito bite response.

J Dermatol 2018 Dec 24;45(12):1471-1474. Epub 2018 Oct 24.

Department of Dermatology, Tokyo Medical and Dental University, Tokyo, Japan.

Mosquito bite reactions consist of an immediate response characterized by an erythema and a wheal, which peaks at 20 min, and a delayed response characterized by a papule and/or an erythema, which peaks at 24 h. Mosquito bite reactions progress from stage I to stage V as an individual is repeatedly bitten as follows: stage I, neither immediate nor delayed reaction; stage II, delayed reaction; stage III, both immediate and delayed reaction; stage IV, immediate reaction; and stage V, neither immediate nor delayed reaction. In 1985, we conducted a cross-sectional study that demonstrated a positive association between age and stage in response to an Aedes albopictus bite among 162 healthy volunteers. Read More

Eave ribbons treated with the spatial repellent, transfluthrin, can effectively protect against indoor-biting and outdoor-biting malaria mosquitoes.

Malar J 2018 Oct 17;17(1):368. Epub 2018 Oct 17.

Environmental Health and Ecological Sciences Department, Ifakara Health Institute, Ifakara, Tanzania.

Background: Long-lasting insecticide-treated nets and indoor residual spraying protect against indoor-biting and indoor-resting mosquitoes but are largely ineffective for early-biting and outdoor-biting malaria vectors. Complementary tools are, therefore, needed to accelerate control efforts. This paper describes simple hessian ribbons treated with spatial repellents and wrapped around eaves of houses to prevent outdoor-biting and indoor-biting mosquitoes over long periods of time.

Dramatic decreases of malaria transmission intensities in Ifakara, south-eastern Tanzania since early 2000s.

Malar J 2018 Oct 16;17(1):362. Epub 2018 Oct 16.

Environmental Health and Ecological Science Department, Ifakara Health Institute, P. O. Box 53, Ifakara, Tanzania.

Background: Ongoing epidemiological transitions across Africa are particularly evident in fast-growing towns, such as Ifakara in the Kilombero valley, south-eastern Tanzania. This town and its environs (population ~ 70,000) historically experienced moderate to high malaria transmission, mediated mostly by Anopheles gambiae and Anopheles funestus. In early 2000s, malaria transmission [Plasmodium falciparum entomological inoculation rate (PfEIR)] was estimated at ~ 30 infectious bites/person/year (ib/p/yr). Read More

Host Decoy Trap (HDT) with cattle odour is highly effective for collection of exophagic malaria vectors.

Parasit Vectors 2018 Oct 15;11(1):533. Epub 2018 Oct 15.

Natural Resources Institute, University of Greenwich at Medway, Chatham Maritime, Kent, ME4 4TB, UK.

Background: As currently implemented, malaria vector surveillance in sub-Saharan Africa targets endophagic and endophilic mosquitoes, leaving exophagic (outdoor blood-feeding) mosquitoes underrepresented. We evaluated the recently developed host decoy trap (HDT) and compared it to the gold standard, human landing catch (HLC), in a 3 × 3 Latin square study design outdoors in western Kenya. HLCs are considered to represent the natural range of Anopheles biting-behaviour compared to other sampling tools, and therefore, in principle, provide the most reliable profile of the biting population transmitting malaria.

Department of Emergency, Taihe Hospital, Hubei University of Medicine, Affiliated Hospital of Hubei University of Medicine, Shiyan 442000, Hubei, China. Corresponding author: Xiao Min, Email:

Objective: To improve the diagnosis and treatment of wasp sting, summarize the experience, the experts from Chinese Society of Toxicology Poisoning and Treatment of Specialized Committee, Hubei Emergency Medicine Committee of Chinese Medical Association and Hubei Provincial Poisoning and Occupational Disease Union made the Expert consensus statement on standardized diagnosis and treatment of wasp stings in China on the development of domestic and oversea in this field. The consensus statement emphasized the idea of staged treatment, different treatments at different stages, and strived to achieve bundling and individuation. To achieve the four pairs of different concept as earlier as possible, the "two early" (early assessment and early treatment), the "two anti" (anti-anaphylaxis and anti-shock), namely the "two hormone" (adrenaline and glucocorticoid) and the "two hua" (hydration and alkalization), we could avoid or reduce subsequent organ failures, significantly shorten the course and improve prognosis of wasp sting victims.

Insects 2018 Sep 28;9(4). Epub 2018 Sep 28.

Department of Entomology, University of Wisconsin, Madison, WI 53706, USA.

Humans vary in attractiveness to mosquitoes, a phenomenon that is largely attributed to differences in physical cues such as heat and volatile odors emanating from breath and skin. Diet can change human odors but whether specific dietary components alter host attractiveness is largely unexplored. We identified bananas as a target for study following a survey of the internet for advice on avoiding mosquito bites. Read More

Interleukin-6 Gene Polymorphism and the Risk of Systemic Inflammatory Response Syndrome Caused by Wasp Sting Injury.

DNA Cell Biol 2018 Dec 28;37(12):967-972. Epub 2018 Sep 28.

4 Department of Pulmonary and Critical Care Medicine, Institute of Respiratory Medicine, Taihe Hospital, Hubei University of Medicine, Shiyan, China.

Previous studies have shown that serum levels of interleukin-6 (IL-6), which plays an important role in the development of systemic inflammatory response syndrome (SIRS), is significantly increased in wasp sting patients. However, the association between IL-6 gene variants and the risk of SIRS development in these patients is not clearly understood. In this study, we investigated the association between IL-6 gene polymorphism in the promoter region and the risk of SIRS in wasp sting patients. Read More
