Severe Necrotizing Community‐Acquired Pneumonia and Bilateral Empyema in an Immunocompetent Patient due to Fusobacterium necrophorum

Case Reports in Pulmonology, Volume 2026, Issue 1, 2026.
Necrotizing pneumonia and empyema caused by Fusobacterium necrophorum are uncommon. The classical presentation of Lemierre′s syndrome, characterized by pharyngotonsillitis and internal jugular vein thrombosis, is not always observed, and incomplete and atypical variants can cause diagnostic uncertainty and delay in treatment.

Borrelia miyamotoi infection in nature and in humans [PDF]

Clinical Microbiology and Infection, 2015
Borrelia miyamotoi is a relapsing fever Borrelia group spirochete that is transmitted by the same hard-bodied (ixodid) tick species that transmit the agents of Lyme disease. It was discovered in 1994 in Ixodes persulcatus ticks in Japan. B. miyamotoi species phylogenetically cluster with the relapsing fever group spirochetes, which usually are ...

Ecological dynamics of blacklegged ticks, vertebrate hosts, and associated zoonotic pathogens in northeastern forests

Ecosphere, Volume 16, Issue 12, December 2025.
Abstract Specific host‐tick interactions in temperate forest systems influence variation in density and infection prevalence of nymphal blacklegged tick (Ixodes scapularis). The density of infected nymphs (DIN), which is the product of nymphal infection prevalence (NIP) and density of questing nymphs (DON), influences the risk of human exposure to tick‐

Molecular Characterization of Anaplasma , Ehrlichia, Babesia , and Borrelia in Ticks from Guangdong Province of Southern China

Zoonoses, 2023
Tick-borne pathogens have become emerging global health threats in humans and animals. The objective of the present study was to investigate Anaplasma, Ehrlichia, Babesia , and Borrelia in ticks in southern China. Ticks were collected from animals and

First evidence of established populations of the taiga tick Ixodes persulcatus (Acari: Ixodidae) in Sweden [PDF]

, 2016
Background: The tick species Ixodes ricinus and I. persulcatus are of exceptional medical importance in the western and eastern parts, respectively, of the Palaearctic region. In Russia and Finland the range of I. persulcatus has recently increased.

Navigating infection by pathogenic spirochetes: The host‐bacteria interface at the atomic level

Protein Science, Volume 34, Issue 7, July 2025.
Abstract Pathogenic spirochetes bind and interact with various host structures and molecules throughout the course of infection. By utilizing their outer surface molecules, spirochetes can effectively modulate their dissemination, interact with immune system regulators, and select specific destination niches within the host.

Borrelia miyamotoi BipA-like protein, BipM, is a candidate serodiagnostic antigen distinguishing between Lyme disease and relapsing fever Borrelia infections

Ticks and Tick-Borne Diseases
A Borrelia miyamotoi gene with partial homology to bipA of relapsing fever spirochetes Borrelia hermsii and Borrelia turicatae was identified by a GenBank basic alignment search analysis.

Homology of variable major protein genes between Borrelia hermsii and Borrelia miyamotoi [PDF]

FEMS Microbiology Letters, 1996
Antigenic variation has been studied in detail for the etiological agent of relapsing fever, Borrelia hermsii. The variable major proteins (vmps) are found at its cell surface, enabling it to avoid the host's immune response. We have cloned and sequenced the vmp-gene (vmp)-like sequences from the Borrelia miyamotoi strains HT31 and FR64b and the ...

There Goes the Neighbourhood—A Multi‐City Study Reveals Ticks and Tick‐Borne Pathogens Commonly Occupy Urban Green Spaces

Zoonoses and Public Health, Volume 72, Issue 3, Page 313-323, May 2025.
ABSTRACT Introduction Humans acquire tick‐borne pathogens (TBPs) from infected ticks contacted during outdoor activities. Outdoor activity is at its highest in urban green spaces, where the presence of tick populations has increasingly been observed. Consequently, more insight into factors influencing the presence of ticks therein is needed.

The Release of Non‐Native Gamebirds Is Associated With Amplified Zoonotic Disease Risk

Ecology Letters, Volume 28, Issue 4, April 2025.
Spillback is potentially an important mechanism by which non‐natives contribute to zoonotic disease emergence. We capitalise on quasi‐experimental releases of non‐native pheasants (Phasianus colchicus) to compare native pathogen prevalence between sites with similar local conditions but different non‐native densities. Prevalence of Borrelia sp.
