on the serological diagnosis using the conventional Widal test, the correct interpretation of the results of which is beset with many difficulties. The discovery by Felix and Pitt (1934) of a Vi antigen of B. typhosus, and its serumcounterpart Vi antibody in the sera of typhoid patients and carriers, opened up a new serological approach to the problem of diagnosis of typhoid infection. Bensted ...

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.

The knowledge of serological reactions has opened a field of research dealing with the specific configurations existing in the chemical constituents of organisms. The results of agglutinin and lysin reactions and the use of the absorption method have disclosed an unexpected variety of structures as exemplified by the existence of differently reacting groups in a single kind of cells, of differe...

Agglutinins are formed within the draining lymph nodes of mice, following intradermal injections of killed cultures of microorganisms.

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...

The genus Brucella comprises various species of both veterinary and human medical importance. All species are genetically highly related to each other, sharing intra-species average nucleotide identities (ANI) of > 99%. Infections occur among various warm-blooded animal species, marine mammals, and humans. Until recently, amphibians had not been recognized as a host for Brucella. In this study,...

Following the recent discovery of new Brucella strains from different animal species and from the environment, ten Brucella species are nowadays included in the genus Brucella. Although the intracellular trafficking of Brucella is well described, the strategies developed by Brucella to survive and multiply in phagocytic and non-phagocytic cells, particularly to access nutriments during its intr...
