Adrenal Steroids Modulate Fibroblast-Like Synoviocytes Response During B. abortus Infection [PDF]

Frontiers in Endocrinology, 2019
Brucella abortus stimulates an inflammatory immune response that stimulates the endocrine system, inducing the secretion of dehydroepiandrosterone (DHEA) and cortisol. In humans, the active disease is generally present as osteoarticular brucellosis.

Immunization with Brucella abortus S19Δper Conferred Protection in Water Buffaloes against Virulent Challenge with B. abortus Strain S544. [PDF]

Vaccines (Basel), 2021
Vaccination of cattle and buffaloes with Brucella abortus strain 19 has been the mainstay for control of bovine brucellosis. However, vaccination with S19 suffers major drawbacks in terms of its safety and interference with serodiagnosis of clinical infection.

Hepatic Stellate Cells and Hepatocytes as Liver Antigen-Presenting Cells during B. abortus Infection [PDF]

Pathogens, 2020
In Brucellosis, the role of hepatic stellate cells (HSCs) in the induction of liver fibrosis has been elucidated recently. Here, we study how the infection modulates the antigen-presenting capacity of LX-2 cells.

B. Abortus Modulates Osteoblast Function Through the Induction of Autophagy. [PDF]

Front Cell Infect Microbiol, 2018
Osteoarticular brucellosis is the most common localization of human active disease. Osteoblasts are specialized mesenchymal-derived cells involved in bone formation and are considered as professional mineralizing cells. Autophagy has been involved in osteoblast metabolism.

Brucella abortus interferes with the inflammatory response and tissue repair in mice [PDF]

Scientific Reports
Brucellosis caused by Brucella spp. is considered a debilitating chronic zoonotic disease. B. abortus, which is endemic in many countries, is responsible for chronic bovine and human infections.

Rapid, ultrasensitive, and highly specific identification of Brucella abortus utilizing multiple cross displacement amplification combined with a gold nanoparticles-based lateral flow biosensor

Frontiers in Microbiology, 2022
Brucella abortus (B. abortus) as an important infectious agent of bovine brucellosis cannot be ignored, especially in countries/regions dominated by animal husbandry. Thus, the development of an ultrasensitive and highly specific identification technique

A Label-Based Polymer Nanoparticles Biosensor Combined with Loop-Mediated Isothermal Amplification for Rapid, Sensitive, and Highly Specific Identification of Brucella abortus

Frontiers in Bioengineering and Biotechnology, 2021
Brucella abortus (B. abortus), an important zoonotic pathogen in Brucella spp., is the major causative agent of abortion in cattle (namely, bovine brucellosis).

Molecular characterization of Brucella spp. from seropositive herds of cattle farmed at the wildlife–livestock–human interface in Rwanda

Frontiers in Veterinary Science, 2022
Seroprevalence studies showed that brucellosis is prevalent in cattle in Rwanda with no recent study on the characterization of Brucella spp. Therefore, this study aimed to characterize Brucella spp. in seropositive herds of cattle farmed at the wildlife–

Antibody responses to Brucella abortus 2308 in cattle vaccinated with B. abortus RB51 [PDF]

Infection and Immunity, 1996
Cattle vaccinated with Brucella abortus rough strain RB51 (SRB51) produced small amounts of serum immunoglobulin G (IgG) but no IgM antibody to smooth strain 2308 (S2308) bacteria and produced no IgG or IgM antibody to S2308 lipopolysaccharide (LPS). Western immunoblot analysis revealed that antiserum from SRB51-vaccinated cattle contained IgG antibody

Specific Detection and Differentiation Between Brucella melitensis and Brucella abortus by a Duplex Recombinase Polymerase Amplification Assay

Frontiers in Veterinary Science, 2020
Brucellosis is a highly contagious zoonosis caused by a species under the genus Brucella. A duplex recombinase polymerase amplification (Duplex RPA) assay for the specific detection of Brucella melitensis and Brucella abortus was developed in this study.
