The patterns of susceptibility to hydrophobic and hydrophilic drugs and the uptake of the fluorescent probe N-phenyl-naphthylamine in Brucella spp., Haemophilus influenzae, Escherichia coli, and deep rough Salmonella minnesota mutants were compared. The results show that the outer membranes of smooth and naturally rough Brucella spp. do not represent barriers to hydrophobic permeants and that t...

Brucella endocarditis, despite its high mortality rate with combined medical and surgical treatment, has a low occurrence rate in cases of brucellosis and has been endemic in regions surrounding Turkey. Rarely, patients with infective endocarditis with common microorganisms develop a splenic abscess. A patient is reported on with brucella endocarditis and persistent fever. An occult splenic abs...

INTRODUCTION In previous articles the distribution and diversity of Brucella sp infections has been covered. In addition the evasive mechanisms used by Brucella spp in avoiding the innate and acquired immune systems has been discussed in detail. This article will cover diagnostic tests and recent work on Brucella testing and the possible implications in strategies for diagnosis and control. The...

Quantitative cross precipitation studies with goat antisera show the three endoantigens of the brucella to be serologically distinguishable. Although the endoantigens of Br. abortus and Br. suis are very similar, they do not react identically, permitting the serological distinction of the two organisms. These differences in cross precipitation may be used to identify an organism of the brucella...

background: brucellosis is one of the most common zoonosis in middle east and iran. objectives: the purpose of this study was genomic detection of brucella spp. in sero-positive dairy cattle. methods: we have collected 28,519 blood samples from cows during 2012-2013. samples were screened by slide and tube agglutination and 2-mercaptoethanol tests. samples with anti-brucella antibodies titer ≥ ...

Brucellosis in Humans with the Approach of Brucella Species Contamination Unpasteurized Milk and Dairy Products from Hamadan, Iran

BACKGROUND Lack of clear risk factor identification is the main reason for the persistence of brucellosis infection in the Chinese population, and there has been little assessment of the factors contributing to Brucella contamination of raw whole milk. The purpose of this study was to identify risk factors affecting Brucella contamination of raw milk, and to evaluate effective measures for dise...

Brucella are highly infectious bacterial pathogens responsible for brucellosis, a frequent worldwide zoonosis. The Brucella genus has recently expanded from 6 to 11 species, all of which were associated with mammals; The natural host range recently expanded to amphibians after some reports of atypical strains from frogs. Here we describe the first in depth phenotypic and genetic characterizatio...

Some sites of extrapulmonary tuberculosis and focal complications of brucellosis are very difficult to differentiate clinically, radiologically, and even histopathologically. Conventional microbiological methods for the diagnosis of extrapulmonary tuberculosis and complicated brucellosis not only lack adequate sensitivity, they are also time consuming, which could lead to an unfavourable progno...
