Special Issue Information
Dear Colleagues,
Pathogenic Leptospira spp. are the etiologic agents of leptospirosis. The disease is the most spread zoonosis. The global burden of leptospirosis is estimated to be over one million annual cases. In developing countries, areas with inadequate infrastructure favor the proliferation of rats, the main reservoir of Leptospira. Infection occurs generally through direct or indirect contact with the urine of infected animals. Symptoms of leptospirosis are similar to acute febrile syndromes and, therefore, is misdiagnosed, and, most probably, underestimate. In developed countries, this disease is mostly associated with recreational activities or occupational activities. Leptospirosis has also an economic impact worldwide as it affects livestock, by decreasing milk production and causing premature death.
Currently, bacterin-based immunization using whole inactivated bacteria cells are the only options for the prevention of leptospirosis. Nevertheless, this approach is limited by a series of disadvantages involving short-term immunity and the absence of cross-reactivity among serovars. Difficulties involved to implement mutagenesis of Leptospira, allied to the lack of molecular aspects of leptospiral pathogenesis and immune response involved during leptospiral infection have impaired the development of effective strategies to control this disease.
This Research Topic aims to enhance our knowledge of mutagenesis, host–pathogen interactions, immune response mechanisms associated with pathogenic Leptospira in hosts.
This includes:
- Identification of surface-exposed immunogenic targets;
- Biological aspects of leptospiral mutagenesis;
- Molecular and cellular aspects of host–pathogen interactions;
- Animal models for the study of leptospiral mutants;
- Immunization and protection against lethal infection in the hamster model of leptospirosis.

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. Pathogens 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 2200 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.

Benefits of Publishing in a Special Issue
- Ease of navigation: Grouping papers by topic helps scholars navigate broad scope journals more efficiently.
- Greater discoverability: Special Issues support the reach and impact of scientific research. Articles in Special Issues are more discoverable and cited more frequently.
- Expansion of research network: Special Issues facilitate connections among authors, fostering scientific collaborations.
- External promotion: Articles in Special Issues are often promoted through the journal's social media, increasing their visibility.
- e-Book format: Special Issues with more than 10 articles can be published as dedicated e-books, ensuring wide and rapid dissemination.
