Special Issue Information

Dear Colleagues,

This Special Issue is dedicated to addressing the urgent challenge presented by the increasing prevalence of ticks and tick-borne diseases around the globe. Authored by leaders in the field, the articles in this collection aim to investigate every aspect of the triad tick–host–pathogen, unraveling molecular mechanisms, highlighting significant information gaps, and identifying high-priority needs essential to advancing our understanding of ticks and tick-borne pathogens (viruses, bacteria, and parasites), and pioneering innovative methods or strategies for the understanding, management, and control of ticks and tick-borne pathogens.

Furthermore, this Special Issue brings together urgently needed multidisciplinary and international collaborations, which include microbiology, virology, biochemistry, molecular biology, genetics, cell biology, epidemiology, entomology, immunology, etc., covering a broad spectrum in addressing tick-borne pathogen challenges affecting human and animal health. As Guest Editors of this Special Issue, we would like to invite you to submit original research papers, short communications, and mini-reviews that facilitate the dissemination of crucial information pertinent to tick biology and tick-borne pathogen infection, transmission, and control.

Manuscript Submission Information

Manuscripts should be submitted online at www.mdpi.com by registering and logging in to this website. Once you are registered, click here to go to the submission form. Manuscripts can be submitted until the deadline. All submissions that pass pre-check are peer-reviewed. Accepted papers will be published continuously in the journal (as soon as accepted) and will be listed together on the special issue website. Research articles, review articles as well as short communications are invited. For planned papers, a title and short abstract (about 100 words) can be sent to the Editorial Office for announcement on this website.

Submitted manuscripts should not have been published previously, nor be under consideration for publication elsewhere (except conference proceedings papers). All manuscripts are thoroughly refereed through a single-blind peer-review process. A guide for authors and other relevant information for submission of manuscripts is available on the Instructions for Authors page. Microorganisms is an international peer-reviewed open access monthly journal published by MDPI.

Please visit the Instructions for Authors page before submitting a manuscript. The Article Processing Charge (APC) for publication in this open access journal is 2700 CHF (Swiss Francs). Submitted papers should be well formatted and use good English. Authors may use MDPI's English editing service prior to publication or during author revisions.

Babesia microti is a protozoan that infects red blood cells, causing hemolytic anemia and flu-like symptoms in humans. Understanding co-infections is crucial for the better diagnosis, treatment, and management of tick-borne diseases. This study examined the prevalence of Babesia microti co-infection with other prevalent tick-borne pathogens in Pennsylvania. The dataset acquired from the Dr. Jane Huffman Wildlife Genetics Institute included passive surveillance data from Ixodes spp. from 2021 to 2023. Submitted ticks were screened for tick-borne pathogens using species-specific TaqMan qPCR. Of the 793 B. microti-positive ticks pulled for analysis, 65.0% were co-infected with other pathogens (n = 516). Notably, 60.9% of the B. microti-positive ticks were co-infected with Borrelia burgdorferi, 10.2% with Anaplasma phagocytophilum Ap-ha, and 7.5% carried a triple co-infection with B. burgdorferi and A. phagocytophilum Ap-ha. The rates of B. microti infection and its co-infections are on the rise, with patterns observed in Pennsylvania and other regions of the USA. While other studies have collected both nymphal and adult ticks to screen for co-infections in Pennsylvania, our study stood out as a unique contribution to the field by focusing exclusively on B. microti-positive ticks. The continued monitoring of tick-borne co-infections is vital to prevent misdiagnosis and ensure effective treatment regimens. Full article
