Francisella tularensis endocarditis is rare and difficult to diagnose, and only a few cases have been described. We report two new cases of endocarditis due to F. tularensis subsp. holarctica, with a favorable evolution after appropriate antibiotic therapy and valve replacement surgery, and review the 5 other cases reported in the literature. This rare infection may be suspected based on the local epidemiology and the patient's exposure factors. A regimen of ciprofloxacin and gentamicin, combined with surgical valve replacement if necessary, appears to be effective in treating F. tularensis endocarditis.

Background: Point of need diagnostics provide efficient testing capability for remote or austere locations, decreasing the time to answer by minimizing travel or sample transport requirements. Loop-mediated isothermal amplification (LAMP) is an appealing technology for point-of-need diagnostics due to its rapid analysis time and minimal instrumentation requirements.
Methods: Here, we designed and optimized nine LAMP assays that are sensitive and specific to targeted bacterial select agents including Bacillus anthracis, Francisella tularensis, Yersinia pestis, and Brucella spp.

Introduction: In winter 2021/2022, a wolf population in the primeval Białowieża Forest in Poland was struck by an outbreak of severe mange caused by mixed infestations of and mites. We present an epidemiological analysis of this mange which caused significant morbidity and mortality.
Material And Methods: Ten sites known for wolf activity were monitored by camera trapping.

Many pathogens have evolved sophisticated strategies to evade autophagy, a crucial cellular defense mechanism that typically targets and degrades invading microorganisms. By subverting or inhibiting autophagy, these pathogens can create a more favorable environment for their replication and survival within the host. For instance, some bacteria secrete factors that block autophagosome formation, while others might escape from autophagosomes before degradation.

The COVID-19 and mpox crisis has reminded the world of the potentially catastrophic consequences of biological agents. Aside from the natural risk, biological agents can also be weaponized or used for bioterrorism. Dissemination in a population or among livestock could be used to destabilize a nation by creating a climate of terror, by negatively impacting the economy and undermining institutions.

Rodents play a significant role in the transmission of zoonotic diseases; anthropization has increased human contact with these animals, vectors of infectious agents. However, the processes driving parasitism of hosts remains poorly understood. , spp.
