Citrus Flavoring Is Weaponized Against Insect-Borne Diseases

The E.P.A. has approved nootkatone, which is found in cedars and grapefruit. It repels ticks, mosquitoes and other dangerous bugs for hours, but is safe enough to eat.

Immunobiology. 2021 Jul 13;226(5):152091. doi: 10.1016/j.imbio.2021.152091. Online ahead of print.ABSTRACTThe spike protein of coronavirus is key target for drug development and other pharmacological interventions. In current study, we performed an integrative approach to predict antigenic sites in SARS-CoV-2 spike receptor binding domain and found nine potential antigenic sites. The predicted antigenic sites were then assessed for possible molecular similarity with other known antigens in different organisms. Out of nine sites, seven sites showed molecular similarity with 54 antigenic determinants found in twelve pathogen...

Availability of highly parallelized immunoassays has renewed interest in the discovery of serology biomarkers for infectious diseases. Protein and peptide microarrays now provide a rapid, high-throughput platform for immunological testing and validation of potential antigens and B-cell epitopes. However, there is still a need for tools to prioritize and select relevant probes when designing these arrays. In this work we describe a computational method called APRANK (Antigenic Protein and Peptide Ranker) which integrates multiple molecular features to prioritize potentially antigenic proteins and peptides in a given pathoge...

Date: July 12, 2021 Issue #:  1628Summary:  The Centers for Disease Control and Prevention (CDC) and the Environmental Protection Agency (EPA) recommend using insect repellents to prevent infections transmitted by mosquitoes and ticks. Insect repellents applied to exposed skin should be used in conjunction with other preventive measures such as wearing pants and long-sleeved shirts and avoiding outdoor activities during peak mosquito-biting times. Mosquitoes can transmit diseasecausing pathogens, including Zika, chikungunya, dengue, West Nile, eastern equine encephalitis, and yellow fever virus...

(TellMed Strategies) Bay Area Lyme Foundation, a leading sponsor of Lyme disease research in the U.S., today announced the publication of new data finding that five herbal medicines had potent activity compared to commonly-used antibiotics in test tubes against Babesia duncani, a malaria-like parasite found on the West Coast of the U.S. that causes the disease babesiosis.

Blood-feeding arthropods are considered an enormous public health threat. They are vectors of a plethora of infectious agents that cause potentially fatal diseases like Malaria, Dengue fever, Leishmaniasis, and Lyme disease. These vectors shine due to their own physiological idiosyncrasies, but one biological aspect brings them all together: the requirement of blood intake for development and reproduction. It is through blood-feeding that they acquire pathogens and during blood digestion that they summon a collection of multisystemic events critical for vector competence. The literature is focused on how classical immune p...

Deaths approaching a million globally, 22 million infected and growing. Brazil, India, the US and Russia accounting for almost 50% of the total cases in the world. Medically the promise of a vaccine is given as signs of hope; what surprises awaits us when such a vaccine is available, would be another story. Economically, to address the uncertainty and the grim future ahead, the UN, some governments and even Joe Biden the US Presidential hopeful, are waving ...

Ticks and mosquitoes don’t care about COVID-19 safety protocols. They don’t care that people are trying to squeeze out the last moments of this restrictive summer by getting outdoors, hiking, or just sitting on their decks at night and feeling something that’s close to normal. COVID-19 has commanded our attention and caused people to adapt their behaviors to prevent one major health concern, but it doesn’t mean others have been eliminated. “Masks and social distancing will do nothing to protect you from what ticks and mosquitoes potentially carry,” says Dr. Todd Ellerin, director of infe...

Mosquito bites may be a nuisance, but fortunately, in the U.S., they tend to amount to nothing more than that. Upon being bitten, most Americans experience a bit of swelling and itchiness, and nothing more. However, there are exceptions to this, including stronger allergic reactions to bites and cases of mosquito-borne illness.  Insect and arachnid bites, including ticks, account for approximately 2,000 cases of malaria and 30,000 cases of Lyme disease in the U.S. annually. In addition, millions of people worldwide die of malaria each year. It is helpful to protect yourself against insect bites, not only to avoid pesk...

Abstract Ticks are the most important vectors of human pathogens, leading to increased public health burdens worldwide. Tick-borne pathogens include viruses (e.g. tick-borne encephalitis and Powassan); bacteria, such as the causative agents of Lyme disease, spotted fever rickettsiosis and human anaplasmosis; and malaria-like protozoan parasites causing babesiosis. Tick-borne diseases are emerging due to the geographical expansion of their tick vectors, especially in the northern hemisphere. Two examples of this phenomenon are Ixodes scapularis and Amblyomma americanum, which have expanded their ranges in the USA i...

(Bloomberg) — There are four critical facets of pandemic prevention, according to Lee Hannah, senior scientist at Conservation International. Three of them make immediate sense against the backdrop of our current emergency: stockpile masks and respirators; have testing infrastructure ready; and ban the global wildlife trade, including the open animal markets where COVID-19 may have first infected people. His fourth recommendation is more grandiose: “Take care of nature.” The assault on ecosystems that allowed COVID-19 to jump from animals to humans went far beyond merchants hunting and selling rare wildli...
