Killing of Brucella abortus by bovine serum [PDF]

Infection and Immunity, 1988
Studies of the serum bactericidal system in bovine brucellosis were undertaken to investigate the role of the humoral immune response in protection of cattle against the facultative intracellular parasite Brucella abortus. Fresh sera from normal control cattle, infected cattle, and cattle immunized with B.

Diagnostic Performance of Four Serological Assays for Bovine Brucellosis and Optimised Cutoff Thresholds in an Endemic Region of Iran

Veterinary Medicine and Science, Volume 11, Issue 5, September 2025.
A Venn diagram representing the overlaps and unique sets between four common serological tests used for Brucellosis detection: I‐ELISA, RBT, Wright and 2‐ME. Each circle corresponds to one of the tests, with varying levels of overlap indicating the number of positives shared between these tests.

RecA and RadA Proteins of Brucella abortus Do Not Perform Overlapping Protective DNA Repair Functions following Oxidative Burst [PDF]

, 2006
Very little is known about the role of DNA repair networks in Brucella abortus and its role in pathogenesis. We investigated the roles of RecA protein, DNA repair, and SOS regulation in B. abortus.

A BtpB‐Deleted Brucella Vaccine Strain Provides Dual Advantages: Enhanced Protection and Diagnostic Differentiation Capability in Mice

Microbial Biotechnology, Volume 18, Issue 9, September 2025.
The Brucella A19ΔBtpB strain induces robust cellular immunity, reduces organ damage, protects mice against M28 infection and enables serological differentiation from other Brucella strains via iELISA. ABSTRACT The Brucella abortus A19 attenuated live vaccine poses potential infection risks during practical applications and interferes with serological ...

Isolation, Identification and Molecular Characterization of Brucella abortus from Bovines

Journal of Pure and Applied Microbiology, 2017
Brucellosis is an important zoonosis and a significant cause of reproductive losses in animals. Abortion, placentitis, epididymitis and orchitis are the most common clinical manifestations in animals.

The endoribonuclease YbeY is linked to proper cellular morphology and virulence in 2 Brucella abortus [PDF]

, 2018
The endoribonuclease YbeY is one of the most well conserved proteins across the kingdoms of life. In the present study, we demonstrate that YbeY in Brucella abortus is linked to a variety of important activities, including proper cellular morphology ...

An HWE‐Family Histidine Kinase Modulates Brucella Cell Envelope Properties and Host Innate Immune Response

Molecular Microbiology, Volume 124, Issue 3, Page 245-258, September 2025.
The HWE‐family histidine kinase PhyK regulates the cell envelope structure of the intracellular pathogen Brucella ovis and affects how the host immune system responds to this bacterium. Deletion of phyK alters bacterial survival in the face of detergent stress and reduces immune activation in infected macrophages.

The Role of Foxes in Transmitting Zoonotic Bacteria to Humans: A Scoping Review

Zoonoses and Public Health, Volume 72, Issue 6, Page 485-500, September 2025.
ABSTRACT Zoonotic diseases inflict substantial burdens on human and animal populations worldwide, and many of these infections are bacterial. An Australian study investigating environmental risk factors for Buruli ulcer in humans detected the causative agent, Mycobacterium ulcerans , in the faeces of wild foxes, a novel finding that suggests foxes may ...

The Cellular Immunoprotection of BALB/C mice vaccinated with Salt-Extractable Brucella abortus S19 antigens and Immunoadjuvant βeta-glucan challenged with Brucella abortus Virulent Strain

The Iraqi Journal of Veterinary Medicine, 2015
The aim of this study was to evaluate the cellular immune responses of salt-Extractable Brucella abortus S19 antigens with immunoadjuvant soluble βeta-glucan in BALB/C mice later challenged with B. abortus virulent strain.
