Reassessment of the genetic basis of natural rifampin resistance in the genus Rickettsia

MicrobiologyOpen, Volume 13, Issue 4, August 2024.
Contrary to previous studies, the natural resistance of Rickettsia, a genus of intracellular bacteria, to the antibiotic rifampin is not solely due to the Leu‐973 residue in the RNA polymerase β subunit. Abstract Rickettsia, a genus of obligate intracellular bacteria, includes species that cause significant human diseases.

Spatial Distribution and Pathogen Profile of Dermacentor reticulatus Ticks in Southeastern Poland: A Genetic and Environmental Analysis

Transboundary and Emerging Diseases, Volume 2024, Issue 1, 2024.
In recent years, significant changes have been observed in the distribution and abundance of local Dermacentor reticulatus populations. However, changes in D. reticulatus dynamics have not been studied in southeastern Poland. Our objective was to enhance our understanding of the environmental factors influencing the occurrence and density of D ...

Difficulty in the Clinical Diagnosis of Tularemia: Highlighting the Importance of a Physical Exam

Case Reports in Pediatrics, Volume 2018, Issue 1, 2018., 2018
We report an 18‐month‐old male who presented with fever and nonspecific symptoms. He was evaluated for multiple differential diagnoses including Kawasaki disease and JIA and received treatment for them. After he was readmitted, tularemia was considered based on the physical exam finding of an ulcer on the scalp and enlarged lymph nodes.
