An Overview of Pathogen Recognition Receptors for Innate Immunity in Dental Pulp

Mediators of Inflammation, Volume 2015, Issue 1, 2015., 2015
Pathogen recognition receptors (PRRs) are a class of germ line‐encoded receptors that recognize pathogen‐associated molecular patterns (PAMPs). The activation of PRRs is crucial for the initiation of innate immunity, which plays a key role in first‐line defense until more specific adaptive immunity is developed.

Host–Pathogen–Vector Continuum in a Changing Landscape: Potential Transmission Pathways for Bartonella in a Small Mammal Community

Ecology and Evolution, Volume 15, Issue 4, April 2025.
This study focuses on Bartonella spp. (a Gram‐negative bacteria) in small mammals and their ectoparasites within a rainforest human‐use landscape. We found that a high proportion (40.56%) of the tested small mammals across five species and two sites carry Bartonella, with prevalence being positively correlated with aggregated ectoparasite load. Despite

Campylobacter jejuni gene cj0511 encodes a serine peptidase essential for colonisation

FEBS Open Bio, Volume 4, Issue 1, Page 468-472, January 01, 2014., 2014
According to MEROPS peptidase database, Campylobacter species encode 64 predicted peptidases. However, proteolytic properties of only a few of these proteins have been confirmed experimentally. In this study we identified and characterised a Campylobacter jejuni gene cj0511 encoding a novel peptidase.

Diversity of bartonellae in mites (Acari: Mesostigmata: Macronyssidae and Spinturnicidae) of boreal forest bats: Association of host specificity of mites and habitat selection of hosts with vector potential

Medical and Veterinary Entomology, Volume 38, Issue 4, Page 518-529, December 2024.
Bats play a major role in the circulation of zoonotic pathogens. Mites (Macronyssidae and Spinturnicidae) may facilitate the long‐term maintenance (and even local recurrence) of Bartonella‐infestations. Mites may transmit several distinct Bartonella strains, which cluster phylogenetically close to Bartonella species known for their zoonotic role ...

Frequencies of Blood Group Systems MNS, Diego, and Duffy and Clinical Phases of Carrion’s Disease in Amazonas, Peru

Interdisciplinary Perspectives on Infectious Diseases, Volume 2014, Issue 1, 2014., 2014
Carrion’s disease (CD), is a human bartonellosis, that is, endemic in the Andes of Peru, Ecuador, and Colombia. Bartonella bacilliformis, a native hemotrophic bacteria, is the causative agent of CD, and the interaction with the host could have produced changes in the gene frequencies of erythrocyte antigens.

Beyond Cat Scratch Disease: A Case Report of Bartonella Infection Mimicking Vasculitic Disorder

Case Reports in Infectious Diseases, Volume 2012, Issue 1, 2012., 2012
Cat scratch disease (CSD) is a bacterial disease caused by Bartonella henselae and it is mainly characterized by self‐limiting lymphadenopathy in the draining site of a cat scratch or bite. We report a patient with history of fever, swelling lymph nodes, vasculitic‐like skin lesions, and positivity of Bartonella serology initially considered as ...

Development of a System for Genetic Manipulation of Bartonella bacilliformis [PDF]

Applied and Environmental Microbiology, 1999
ABSTRACT Lack of a system for site-specific genetic manipulation has severely hindered studies on the molecular biology of all Bartonella species. We report the first site-specific mutagenesis and complementation for a Bartonella species. A highly transformable strain of

Natural History of Infection withBartonella bacilliformisin a Nonendemic Population [PDF]

The Journal of Infectious Diseases, 2000
An investigation was performed after an outbreak of bartonellosis in a region of Peru nonendemic for this disorder. Symptoms of acute and chronic bartonellosis were recorded. Serological analysis was performed on 55% of the affected population (554 individuals), 77.5% of whom demonstrated previous infection with Bartonella bacilliformis.
