In previous reports (Elberg and Herzberg, 1953; Herzberg and Elberg, 1953) the isolation and characteristics of a streptomycin-dependent mutant of Brucella melitenis were described.2 The streptomycin-dependent strain retained the biochemical and antigenic characteristics of the virulent parent strain but differed in a requirement for streptomycin for its growth. Growth in vivo was not influence...

The possible role of Brucella spp. in 65 abortion cases, 55 from sheep and 10 from goats, occurring in the birth seasons of 2004 and 2005 in northwestern Turkey was investigated. Colony morphology, agglutination by acriflavin, H2S production, CO2 requirement, dye sensitivity in thionin, basic fuchsin, growth characteristics in streptomycin, lysis with Tbilisi phage, and agglutination with monos...

The gene coding for the major outer membrane protein Omp31 was sequenced in five Brucella species and their biovars. Although the omp31 genes appeared to be highly conserved in the genus Brucella, nine nucleotide substitutions were detected in the gene of Brucella ovis compared to that of Brucella melitensis. As shown by differential binding properties of monoclonal antibodies (MAbs) to the two...

Infection with Brucella spp. continues to pose a human health risk globally despite strides in eradicating the disease from domestic animals. Brucellosis has been an emerging disease since the discovery of Brucella melitensis by Sir David Bruce in 1887. Although many countries have eradicated B. abortus from cattle, in some areas B. melitensis and B. suis have emerged as causes of this infectio...

Isolation and characterisation of Brucella melitensis by bacteriological molecular methods from livestock in North Cyprus | M Demirpence, AM Saytekin, B Sareyyupoglu, OM Esendal Agricultural Journals

Cases of brucellosis were diagnosed in 3-month-old twins and their mother. An epidemiologic survey suggested that raw sheep or goat meat might be the source of Brucella melitensis infection. This finding implies that the increasing threat of brucellosis might affect low-risk persons in urban settings in China.

Brucellosis is a zoonosis of economic importance that reduces productivity in livestock enterprises as it induces abortion in infected animals. A study was designed aimed at detecting Brucella in blood and lymph node specimens from camels by the use of real-time PCR in Iran. Sample collection and DNA extraction were done on blood (n = 135) and lymph node (n = 135) samples collected from 135 cam...

Hapten polysaccharides of Brucella smooth M and A serotypes were prepared from Brucella sp. and Yersinia enterocolitica O:9 by previously described hydrolytic (O chain) or nonhydrolytic (native hapten [NH]) procedures. The purified polysaccharides differed only in the presence (O chain) or absence (NH) of lipopolysaccharide core sugars. The polysaccharides were compared by reverse radial immuno...

Brucellosis is a zoonotic disease; its symptoms and appearances are not exclusive in human and its traditional diagnosis is based on culture, serological methods and conventional PCR. For more sensitive, specific detection and differentiation of Brucella spp., the real time PCR method is recommended. This research has performed to determine the presence and prevalence of Brucella spp. and diffe...
