Development of a p28-based PCR assay for Ehrlichia chaffeensis [PDF]

Molecular and Cellular Probes, 2004
Detection of Ehrlichia chaffeensis is necessary to study interactions between the parasite and its vertebrate and invertebrate hosts. The purpose of this study was to develop a sensitive, specific PCR assay for E. chaffeensis based on the outer membrane protein gene, p28.

Ehrlichiosis in a Recent Liver Transplant Recipient Leading to Multiorgan Failure

Case Reports in Transplantation, 2022
Ehrlichia infection has a broad spectrum of diseases ranging from asymptomatic to fatal. While Ehrlichia often presents as a mild form of the disease in immunocompetent patients, immunosuppressed patients are at increased risk for a more virulent and ...

Descriptive Analysis and Factors Associated With Relapse in Dogs With Presumptive Idiopathic Immune‐Mediated Polyarthritis

Journal of Veterinary Internal Medicine, Volume 39, Issue 5, September/October 2025.
ABSTRACT Background Immune‐mediated polyarthritis (IMPA) is a joint disease common in dogs. Although its prognosis is generally favorable, relapses are frequent, and predictive factors for relapse remain poorly characterized. Objectives To evaluate the outcome of medical management of IMPA in dogs and identify predictive factors for relapse.

Development of mRNA–lipid nanoparticle intrabodies against rickettsial infection

Journal of Biomedical Science
Background Rickettsiosis is among the deadliest vector-borne infectious diseases worldwide, in part because rickettsiae replicate within human cells, where antibodies and most drugs cannot effectively reach this obligatory intracellular pathogen ...

Development of Antisense Tools to Study Bodo saltans and Its Intracellular Symbiont

MicrobiologyOpen, Volume 14, Issue 2, April 2025.
Obligate symbioses present challenges for functional genetic analysis. This study shows that antisense inhibition cannot be used to investigate gene functions in the aquatic symbiosis between Bodo saltans and its bacterial symbiont. Our work stresses the importance of the development of alternative protocols to study the biology of both the ...

Investigation of the Blood Microbiome in Horses With Fever of Unknown Origin

Veterinary Medicine and Science, Volume 11, Issue 2, March 2025.
ABSTRACT Background Fever of unknown origin (FUO) without a respiratory component is a frequent clinical presentation in horses. Multiple pathogens, both tick‐borne and enteric, can be involved as etiologic agents. An additional potential mechanism is intestinal barrier dysfunction.
