This study explored the effects of antimicrobiota vaccines on acquisition Borrelia and Rickettsia, microbiota composition Ixodes ricinus ticks. Using a murine model, we investigated immunological responses to live Staphylococcus epidermidis multi-antigenic peptide (MAP) vaccines. Immunized mice were infected with either afzelii or Rickettsia helvetica, subsequently infested pathogen-free I. nymphs. We monitored tick feeding behavior, survival rates, infection levels. Additionally, employed...

Abstract The Ornithodoros moubata (Om) soft tick, a vector for diseases like tick‐borne human relapsing fever and African swine fever, poses challenges to conventional control methods. With diminishing insecticide efficacy, harnessing the tick's microbiota through innovative approaches microbiota‐driven vaccination emerges as promising strategy sustainable targeted disease control. This study investigated intricate relationship between Pseudomonas , keystone taxon in Om microbiome, its...
Introduction The camel-infesting tick, Hyalomma dromedarii , is a prominent ectoparasite in the Middle East and North Africa (MENA) region, critically impacting camel health acting as vector for tick-borne pathogens. Despite prior studies on its microbiota, effects of geographic origin sex microbial community structure functional stability remain poorly understood. Methods To address this, we characterized bacterial microbiota H. ticks collected from camels Tunisia (TUN) Saudi Arabia (SA)...
Abstract Interactions within the tick microbiome involving symbionts, commensals, and tick‐borne pathogens (TBPs) play a pivotal role in disease ecology. This study explored temporal changes of Rhipicephalus microplus , an important cattle vector, focusing on its interaction with Anaplasma marginale . To overcome limitations inherent sampling methods relying questing ticks, which may not consistently reflect pathogen presence due to variations exposure infected hosts nature, our focused...
Tick-borne pathogens (TBPs) pose a significant threat to livestock, including bovine species. This study aimed investigate TBPs in cattle and ticks across four sampling points, utilizing real-time microfluidic PCR. The results revealed that
Vector-borne diseases (VBDs) pose significant global health threats. The microbiota of arthropod vectors influences their fitness and pathogen acquisition and/or transmission. Here, we review the intricate interplay among immune system, microbiota, pathogens that limits or favors infection. We focused on most important vectors, namely mosquitos, phlebotomines, tsetse flies, triatomines, ticks, expanded our analysis to include nonvector model Drosophila melanogaster for comparison. system are...
Avian malaria infection has been known to affect host microbiota, but the impact of Plasmodium on colonization resistance in bird gut microbiota remains unexplored. This study investigated dynamics relictum canaries, aiming explore hypothesis that modulation by P. would reduce resistance. Canaries were infected with relictum, while a control group was maintained. The results revealed presence blood all canaries. Analysis showed no significant differences alpha diversity metrics between and...
Understanding the intricate ecological interactions within microbiome of arthropod vectors is crucial for elucidating disease transmission dynamics and developing effective control strategies. In this study, we investigated roles Coxiella-like endosymbiont (CLE) Anaplasma marginale across larval, nymphal, adult stages Rhipicephalus microplus. We hypothesized that CLE would show a stable, nested pattern reflecting co-evolution with tick host, while A. exhibit more dynamic, non-nested...
Abstract Background Mosquitoes serve as vectors for numerous pathogens, posing significant health risks to humans and animals. Understanding the complex interactions within mosquito microbiota is crucial deciphering vector-pathogen dynamics developing effective disease management strategies. Here, we investigated nested patterns of Wolbachia endosymbionts Escherichia-Shigella laboratory-reared Culex pipiens f. molestus quinquefasciatus mosquitoes. We hypothesized that would exhibit a...
Abstract Recent studies show that mosquito–microbiota interactions affects vector competence and fitness. We investigated if host antibodies modifying microbiota impact mosquito physiology. focused on three prevalent bacteria (Acinetobacter, Pantoea, Chryseobacterium), originally isolated from the Asian tiger Aedes albopictus. Our goal was to assess of life traits. Female mosquitoes were fed with blood rabbits immunized each bacterium or a mock vaccine. compared various factors, including...
Abstract Background Canine monocytic ehrlichiosis (CME) is caused by the tick-borne pathogen Ehrlichia canis , an obligate intracellular Gram-negative bacterium of family Anaplasmataceae with tropism for canine monocytes and macrophages. The trp36 gene, which encodes major immunoreactive protein TRP36 in E. has been successfully used to characterize genetic diversity this different regions world. Based on sequence analysis, four genogroups, United States (US), Taiwan (TWN), Brazil (BR) Costa...
Hyalomma dromedarii ticks are the main hematophagous ectoparasites of camels, harboring a variety microbes that can affect tick vector competence and pathogen transmission. To better understand microbiome influenced by sex host habitat, we analyzed bacterial community H. male female collected from camel farms, livestock markets, slaughterhouses, representing range major habitats in UAE, sequencing 16S rRNA gene. Tick samples were during 2022 2023. A total 40 (male (15), nymph (10)) selected...
