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 migratory farmers in rural Tanzania using eave ribbons treated with the spatial mosquito repellent, transfluthrin.

Malar J 2019 Dec 10;18(1):414. Epub 2019 Dec 10.

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

Background: Many subsistence farmers in rural southeastern Tanzania regularly relocate to distant farms in river valleys to tend to crops for several weeks or months each year. While there, they live in makeshift semi-open structures, usually far from organized health systems and where insecticide-treated nets (ITNs) do not provide adequate protection. This study evaluated the potential of a recently developed technology, eave ribbons treated with the spatial repellent transfluthrin, for protecting migratory rice farmers in rural southeastern Tanzania against indoor-biting and outdoor-biting mosquitoes.

Prevalence and Impact of Type I Sensitization to Alpha-Gal in Patients Consulting an Allergy Unit.

Int Arch Allergy Immunol 2020 5;181(2):119-127. Epub 2019 Dec 5.

Department of Dermatology, Faculty of Medicine, Eberhard Karls University Tübingen, Tübingen, Germany.

Background: Alpha-gal syndrome is a complex allergy with high clinical relevance regarding mammalian-derived food and drugs and is characterized by the presence of IgE antibodies directed at the carbohydrate galactose-α-1,3-galactose. As not all alpha-gal sIgE-positive individuals pre-sent clinical symptoms upon consumption of mammalian meat, the diagnostic value of alpha-gal sIgE has yet to be clarified.

Objective: To investigate the prevalence of alpha-gal-sIgE positivity among allergy patients, examine the impact of tick bites as associated risk factors and determine the diagnostic value of alpha-gal-sIgE positivity. Read More

A popular Indian clove-based mosquito repellent is less effective against Culex quinquefasciatus and Aedes aegypti than DEET.

PLoS One 2019 5;14(11):e0224810. Epub 2019 Nov 5.

Department of Molecular and Cellular Biology, University of California-Davis, Davis, CA, United States of America.

Insect repellents are widely used as the first line of defense against mosquito bites and transmission of disease-causing agents. However, the cost of daily applications of even the most affordable and the gold standard of insect repellents, DEET, is still high for low-income populations where repellents are needed the most. An Indian clove-based homemade recipe has been presented as a panacea. Read More

Cutis 2019 Sep;104(3):182-183;186

Medical University of South Carolina, Charleston, USA.

Cat fleas (Ctenocephalides felis) often leave cats and dogs to bite humans, causing pruritic lesions of the lower extremities. Once flea bites are confirmed, various efforts can be made to eradicate these pests from the home or pets. Cat fleas also play a role in transmission of vector-borne diseases, especially endemic typhus. Read More

Host Associations Of Biting Midges (Diptera: Ceratopogonidae: ) Near Sentinel Chicken Surveillance Locations In Florida, USA.

J Am Mosq Control Assoc 2019 09;35(3):200-206

University of Florida IFAS, Florida Medical Entomology Laboratory, 200 9th Street SE, Vero Beach, FL 32962.

Quantifying host use is important for understanding transmission of vector-borne pathogens. Despite the importance of biting midges (Diptera: Ceratopogonidae) in pathogen transmission, the vector-host relationships of most species are poorly documented, even in locations where active arbovirus surveillance is conducted. Polymerase chain reaction-based blood-meal analysis was performed on 663 blood-engorged females collected by 7 Florida mosquito control districts at 24 sentinel chicken arbovirus surveillance sites in 2017.
