Characterization Of Tick And Host-Associated Factors Linked To Induction Of Alpha-Gal Syndrome., Surendra Raj Sharma, Surendra Raj Sharma

Dissertations

Alpha-Gal Syndrome (AGS) is a delayed allergic reaction caused by specific IgE antibodies to the oligosaccharide galactose-α-1,3-galactose (α-gal) present in red meat. AGS is a growing concern globally, with over 34,000 confirmed cases in the United States alone. Studies have linked AGS to tick bites, which sensitizes hosts against α-gal antigens and elevates α-gal specific IgE. This dissertation investigates the role of tick and host-associated factors in AGS development. Microbiome analysis of Am. americanum ticks revealed a comprehensive core microbiome profile and showed that new Fransiella-like endosymbionts dominate and outcompete conventional tick Coxiella endosymbionts.
