Guideline for the Diagnosis and Management of Heritable IFNAR1 Deficiency in Oceania

Journal of Paediatrics and Child Health, EarlyView.
ABSTRACT Autosomal recessive interferon alpha and beta receptor subunit 1 (IFNAR1) deficiency is a rare and heritable inborn error of immunity (IEI) predisposing individuals to severe and life‐threatening viral infections. It is more common in people of Western Polynesian ancestry, with estimates of around one in six thousand live births affected, due ...

Preimaginal development of Aedes aegypti L. (Diptera: Culicidae) in brackish water gives rise to adult mosquitoes with thicker cuticles and greater insecticide resistance

Medical and Veterinary Entomology, EarlyView.
The principal arboviral vector Aedes aegypti can develop in coastal brackish water field habitats (0.5–15 g/L salt) with larvae possessing thicker cuticles and greater resistance to the larvicide Temephos. Females emerging from brackish water‐developing preimaginal stages are now shown to have thicker and remodelled leg and abdominal cuticles and ...

Spotted fever group Rickettsia in Haemaphysalis ticks: genetic diversity and first detection of “Candidatus Rickettsia jingxinensis” in India

Ticks and Tick-Borne Diseases
Ticks are important vectors of rickettsial pathogens, particularly in regions where livestock, wildlife, and humans overlap. Despite increasing reports of rickettsioses in India, molecular evidence of Rickettsia species in questing ticks from the Western

Mouse Models of Chikungunya Virus

, 2016
The majority of medical advances have been made using animals. Studies using mouse models of chikungunya-induced disease have proven invaluable for dissecting the intricate nature of the immune response to this viral infection and identifying potential ...

Ingestion of attractive toxic sugar baits containing ivermectin before and after blood feeding affects the biology and reproduction of Aedes aegypti (Diptera: Culicidae)

Medical and Veterinary Entomology, EarlyView.
Attractive toxic sugar bait containing ivermectin (ATSB‐IVM) ingestion markedly reduced blood feeding, survival, oviposition, egg production and larval hatching, with the strongest effects when baits were ingested before blood feeding. Timing of ingestion (48–96 h before or after blood feeding) shaped sublethal impacts across the first and second ...

Chikungunya Epidemic Mortality in India: Lessons from 17th Century Bills of Mortality Still Relevant [PDF]

Chikungunya is a virus spread by the bite of the Aedes mosquito, which recently reemerged as a massive epidemic in the Indian Ocean islands and India. Chikungunya is generally considered self-limiting and has been reported as non-fatal but, since March ...

Effect of blood meals and mating on biodemographic characteristics of Aedes albopictus

Physiological Entomology, EarlyView.
Lifespan did not differ between virgin and mated males and females. The number of blood meals (one and two) significantly reduced adult lifespan compared with those with no blood meal. The effect of the second blood meal doubled females' egg production and their reproductive output.

Photodegradation of commercial insect repellents containing DEET and IR‐3535 under ultraviolet light associated or not with chemical ultraviolet filters evaluated by Raman spectroscopy

Photochemistry and Photobiology, EarlyView.
This study evaluated the photodegradation of commercial insect repellents containing DEET and IR‐3535 under UV‐A and UV‐B irradiation using Raman spectroscopy. Pure DEET and IR‐3535 showed intrinsic photostability, whereas DEET diluted in ethanol and a commercial DEET‐based formulation exhibited significant spectral changes after UV exposure.

Climatic, Socioecological and Environmental Determinants of Aedes spp. Dynamics at the Community Interface: A Systematic Review With Reflections From a One Health Perspective

Tropical Medicine &International Health, EarlyView.
ABSTRACT Background and Objectives Mosquitoes of the genus Aedes, including but not limited to Aedes aegypti, are major vectors of arboviruses such as dengue, Zika and other related diseases. Their global expansion is driven by climate change, globalisation, urbanisation and human mobility.
