[Diphtheria: new clinical presentations of an old disease].

Rev Med Suisse 2019 Apr;15(646):786-790

Laboratoire de bactériologie, Service de médecine de laboratoire, Département diagnostique, HUG, 1211 Genève 14.

Diphtheria is reappearing in a typical cutaneous form where pre-existing skin lesions (wounds or insect bites) become pustular and turn into painful non-healing ulcers. This form is more common among migrants and disadvantaged populations. Lesions can be caused by strains of toxigenic and non-toxigenic Corynebacteria and among them the famous Corynebacterium diphtheriae. Read More

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).

Int J Hyg Environ Health 2019 Apr 7;222(3):355-363. Epub 2019 Mar 7.

United States Army Research Institute of Environmental Medicine, Military Performance Division, 10 General Greene Avenue, Natick, MA, USA. Electronic address:

Permethrin is used to treat clothing as a personal protective measure against insect bites in military and recreational settings, and along with other pyrethroid insecticides, is sprayed in agricultural and residential sites for pest control. The widespread use of permethrin and other pyrethroid insecticides creates a potential for human exposure in occupational and non-occupational populations. This study aims to compare urinary biomarkers of pyrethroid exposure in two US military cohorts to the general US adult population from the 2009-2010 Nutritional Health and Nutrition Examination Survey (NHANES).

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.

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

Variation in the effectiveness of insecticide treated nets against malaria and outdoor biting by vectors in Kilifi, Kenya.

Wellcome Open Res 2017 3;2:22. Epub 2018 Dec 3.

KEMRI-Wellcome Trust Research Programme, Centre for Geographic Medicine Research-Coast, Kilifi, Kenya.

: Insecticide treated nets (ITNs) protect humans against bites from the mosquito vectors that transmit malaria, thereby reducing malaria morbidity and mortality. It has been noted that ITN use leads to a switch from indoor to outdoor feeding among these vectors. It might be expected that outdoor feeding would undermine the effectiveness of ITNs that target indoors vectors, but data are limited. 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

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

Allergen-specific immunoglobulin E in sera of horses affected with insect bite hypersensitivity, severe equine asthma or both conditions.

J Vet Intern Med 2019 Jan 6;33(1):266-274. Epub 2018 Dec 6.

Department of Clinical Research, University of Bern, Berne, Switzerland.

Background: Genetic, epidemiologic, and clinical evidence suggests that, in horses, there are manifestations of hypersensitivity that can occur together.

Objectives: To investigate whether concurrent insect bite hypersensitivity (IBH) and severe equine asthma (EA) is associated with higher allergen-specific and total serum immunoglobulin E (IgE) concentrations than only EA or IBH.

Animals: Healthy control horses (C, n = 40), horses with IBH (IBH, n = 24), severe EA (EA, n = 18), and both conditions (IBH/EA, n = 23) were included. Read More

A case of ulceroglandular tularemia presenting with lymphadenopathy and an ulcer on a linear morphoea lesion surrounded by erysipelas.

Int Med Case Rep J 2018 12;11:313-318. Epub 2018 Nov 12.

Department of Infectious Diseases, Regional Hospital of Bellinzona e Valli, 6500 Bellinzona, Ticino, Switzerland.

Tularemia is a zoonosis caused by the infection of (a gram-negative aerobic bacterium). Transmission to other animals or humans usually occurs through insect or tick bites, direct contact with a contaminated environment (mud or water), infected animals - mainly lagomorphs - or by ingesting undercooked meat or inhaling contaminated dust (hay or soil). This paper discusses the case of a 32-year-old man, who came to our Emergency Room presenting with persistent fever, inguinal lymphadenopathy, and an ulcer on his left lower limb on a linear morphoea lesion that had been there for some time.

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

Active vaccination against interleukin-5 as long-term treatment for insect-bite hypersensitivity in horses.

Allergy 2019 Mar 25;74(3):572-582. Epub 2018 Nov 25.

RIA Immunology, Inselspital, University of Bern, Bern, Switzerland.

Background: Insect-bite hypersensitivity (IBH) in horses is a chronic allergic dermatitis caused by insect bites. Horses suffer from pruritic skin lesions, caused by type-I/type-IV allergic reactions accompanied by prominent eosinophil infiltration into the skin. Interleukin-5 (IL-5) is the key cytokine for eosinophils and we have previously shown that targeting IL-5 by vaccination reduces disease symptoms in horses. 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.
