Previous findings indicate that Brucella antigens and those from nonpathogenic alphaproteobacteria (NPAP) are cross-recognized by the immune system. We hypothesized that immunization with NPAP would protect mice from Brucella infection. Mice were immunized subcutaneously with heat-killed Ochrobactrum anthropi, Sinorhizobium meliloti, Mesorhizobium loti, Agrobacterium tumefaciens, or Brucella me...
In this study, a localized surface plasmon resonance (LSPR) nanobiosensor was designed to quantify anti-Brucella antibodies in the human sera. Smooth Lipopolysaccharide (LPS) extracted from Brucella melitensis via modified hot phenol water method and fixed on of gold nanoparticles by covalent interactions with functionalized nanoparticles. To obtain best performance probe, ratio LPS nanoparticl...
Brucella spp. are facultative intracellular parasitic pathogens that can survive and multiply in professional and nonprofessional phagocytes. These pathogens are responsible for brucellosis, which can cause abortion in domestic animals and undulant fever in humans. Brucella spp. can survive in a variety of cells and their virulence and chronic infections are thought to be due to their ability t...
Pathogenic brucellae are the agent of brucellosis, a disease that causes abortion and infertility in natural hosts such as sheep, goats, or cattle. Brucella melitensis, Brucella abortus, and Brucella suis are the most pathogenic Brucella species for humans and also the most relevant bacteria involved in economical loses and in animal and human health problems. In addition, these Brucella repres...
The letter of Yang et al. (1) is an interesting account of the continuing issues associated with the misidentification of Brucella species by the current commercial identification systems. As mentioned in the letter, we experienced similar issues with the commercial bacterial identification assays that rely on phenotypic laboratory tests (2). These systems remain unreliable for identification o...
Monoclonal antibodies which bind Brucella A lipopolysaccharide (LPS)-specific, M LPS-specific, or cross-reactive epitopes were used as reagents in quantitative dot blot, Western blot (immunoblot), and immunoprecipitation analysis of Brucella whole cells, whole-cell extracts, and purified LPS preparations. This set of monoclonal antibodies detected four unique epitopes on Brucella LPS. The speci...
Brucella abortus is generally known to cause brucellosis in cattle and buffalo. Here, we report the draft genome sequence of Brucella abortus SKN 13, isolated from aborted cattle placenta in the area of Gujarat, India, providing precious resources for comparative genomic analyses of Brucella field strains.
Brucella melitensis is a facultative intracellular bacterium that causes brucellosis, the most prevalent zoonosis worldwide. The Brucella intracellular replicative niche in macrophages and dendritic cells thwarts immune surveillance and complicates both therapy and vaccine development. Currently, host-pathogen interactions supporting Brucella replication are poorly understood. Brucella fuses wi...
BACKGROUND Brucellosis is a zoonosis of public health importance worldwide. In Tanzania, the disease is underreported due to insufficient awareness, inadequate diagnostic protocols, including lack of appropriate reagents for diagnosis. Livestock and wildlife are considered potential sources of infection to humans; however, the role played by these carriers in the epidemiology of the disease in ...
Brucella is an intracellular bacterium that causes chronic brucellosis in humans and various mammals. The identification of host-Brucella interaction is crucial to understand host immunity against Brucella infection and Brucella pathogenesis against host immune responses. Most of the information about the inter-species interactions between host and Brucella genes is only available in the text o...
