Anopheles arabiensis and Anopheles funestus biting patterns in Dielmo, an area of low level exposure to malaria vectors.

Malar J 2020 Jun 26;19(1):230. Epub 2020 Jun 26.

Aix Marseille Univ, IRD, AP-HM, SSA, VITROME, Marseille, France.

Background: In Dielmo, Senegal, the widespread use of long-lasting insecticidal nets has decreased both the incidence of malaria and the density of the Anopheles population. However, persistent low-level malaria transmission may hamper efforts to eliminate the disease. Therefore, continuous monitoring of the vector population is needed in order to improve knowledge of Anopheles biting behaviour and to readjust control interventions. Read More

Factors associated with mobile phone ownership and potential use for rabies vaccination campaigns in southern Malawi.

Infect Dis Poverty 2020 Jun 5;9(1):62. Epub 2020 Jun 5.

The Epidemiology, Economics and Risk Assessment (EERA) Group, The Roslin Institute and The Royal (Dick) School of Veterinary Studies, The University of Edinburgh, Easter Bush Veterinary Centre, Roslin, Midlothian, UK.

Background: Rabies is a fatal but preventable viral disease, which causes an estimated 59 000 human deaths globally every year. The vast majority of human rabies cases are attributable to bites from infected domestic dogs and consequently control of rabies in the dog population through mass vaccination campaigns is considered the most effective method of eliminating the disease. Achieving the WHO target of 70% vaccination coverage has proven challenging in low-resource settings such as Sub Saharan Africa, and lack of public awareness about rabies vaccination campaigns is a major barrier to their success.

James H Diaz

South Med J 2020 Jun;113(6):267-274

From the School of Public Health, Environmental, and Occupational Health Sciences, Louisiana State University Health Sciences Center, New Orleans.

Red meat allergies have followed tick bites on every continent except Antarctica. The sensitizing antigen is galactose-α-1,3-galactose (α-gal), an oligosaccharide constituent of nonprimate blood and meat, acquired by ticks during animal bloodfeeding. Because red meat allergy after tick bites is a worldwide phenomenon, the objectives of this review were to describe the global epidemiology of red meat allergy after tick bites and its immunological mechanisms; to identify the human risk factors for red meat allergy after tick bites; to identify the most common tick vectors of red meat allergy worldwide; to describe the clinical manifestations, diagnostic confirmation, and management of patients with red meat allergy after tick bites; and to recommend strategies for the prevention of tick bites.

Diagnostic and Therapeutic Value of Aptamers in Envenomation Cases.

Int J Mol Sci 2020 May 18;21(10). Epub 2020 May 18.

L'institut du thorax, INSERM, CNRS, UNIV NANTES, F-44007 Nantes, France.

It is now more than a century since Albert Calmette from the Institut Pasteur changed the world of envenomation by demonstrating that antibodies raised against animal venoms have the ability to treat human victims of previously fatal bites or stings. Moreover, the research initiated at that time effectively launched the discipline of toxicology, first leading to the search for toxic venom components, followed by the demonstration of venoms that also contained compounds of therapeutic value. Interest from pharmaceutical companies to treat envenomation is, however, declining, mainly for economic reasons, and hence, the World Health Organization has reclassified this public health issue to be a highest priority concern.

National Estimates of Noncanine Bite and Sting Injuries Treated in US Hospital Emergency Departments, 2011-2015.

South Med J 2020 May;113(5):232-239

From the Department of Medicine, University of Chicago, Chicago, Illinois, the North Carolina Department of Health and Human Services, Raleigh, Marilyn Goss Haskell, Innovative One Health Solutions, Raleigh, North Carolina, and the Rollins School of Public Health, Emory University, Atlanta, Georgia.

Objectives: Injuries resulting from contact with animals are a significant public health concern. This study quantifies and updates nonfatal bite and sting injuries by noncanine sources using the most recent data available (2011-2015) from the National Electronic Injury Surveillance System-All Injury Program with the purpose of using these updates to better understand public health consequences and prevention techniques. Increased rates of bites and stings can be expected in this study's time frame, possibly caused by the increasing human population expanding into animal territories, as well as changes in animal geographic distribution and pet ownership.

Investigating the epithelial barrier and immune signatures in the pathogenesis of equine insect bite hypersensitivity.

PLoS One 2020 28;15(4):e0232189. Epub 2020 Apr 28.

Division of Experimental Clinical Research, Department of Clinical Research and Veterinary Public Health, Vetsuisse Faculty, University of Bern, Bern, Switzerland.

Insect bite hypersensitivity (IBH) is a Th-2, IgE-mediated dermatitis of horses caused by bites of insects of the genus Culicoides that has common features with human atopic dermatitis. Together with Th-2 cells, the epithelial barrier plays an important role in development of type I hypersensitivities. In order to elucidate the role of the epithelial barrier and of the skin immune response in IBH we studied the transcriptome of lesional whole skin of IBH-horses (IBH-LE; n = 9) in comparison to non-lesional skin (IBH-NL; n = 8) as well as to skin of healthy control horses (H; n = 9).

Protecting the peri-domestic environment: the challenge for eliminating residual malaria.

Sci Rep 2020 Apr 27;10(1):7018. Epub 2020 Apr 27.

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

Malaria transmission after universal access and use of malaria preventive services is known as residual malaria transmission. The concurrent spatial-temporal distributions of people and biting mosquitoes in malaria endemic villages determines where and when residual malaria transmission occurs. Understanding human and vector population behaviors and movements is a critical first step to prevent mosquito bites to eliminate residual malaria transmission. Read More
