Background: Human brucellosis is a significant public health problem in many middle east countries including Iran. Brucella organisms, which are small aerobic, facultative intracellular coccobacilli, localize in the reproductive organs of host animals, causing abortions and sterility. They are shed in large numbers in the animal’s urine, milk, placental fluid, and other fluids. Dairy product fr...
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...
BACKGROUND Brucellosis is a widespread zoonotic disease caused by Gram-negative Brucella bacteria. Immunisation with attenuated vaccine is an effective method of prevention, but it can interfere with diagnosis. Live, attenuated Brucella abortus strain 104M has been used for the prevention of human brucellosis in China since 1965. However, at present, no fast and reliable method exists that can ...
Two Gram-negative, non-motile, non-spore-forming, coccoid bacteria (strains CCM 4915(T) and CCM 4916), isolated from clinical specimens of the common vole Microtus arvalis during an epizootic in the Czech Republic in 2001, were subjected to a polyphasic taxonomic study. On the basis of 16S rRNA (rrs) and recA gene sequence similarities, both isolates were allocated to the genus Brucella. Affili...
Detection of Brucella spp. in the Sheep and Goats Milks from Southeastern Iran Using Culture and PCR
Introduction: Brucellosis is a zoonotic disease caused by the members of the genus Brucella. This bacterium is transmitted to humans through exposure to infected animals or via consumption of contaminated dairy products. Cultivation of the bacteria or amplification of its DNA using polymerase chain reaction (PCR) are conventional diagnostic approaches for definitive identification of Brucella i...
The seroprevalence of brucellosis among undiagnosed family members of brucellosis positive patients.
AIM This study investigated the seroprevalence, complications and risk factors of Brucella infection in rural areas of Sivas, Turkey. MATERIALS AND METHODS The study was conducted in three hyperendemic counties for brucellosis known as Gurun, Altinyayla and Kangal in Sivas between April and October in 2011. A total of 1,430 subjects were consulted. RESULTS Of the 1,430 subjects, 217 (15.2%)...
A rapid and simple method for quantitative monitoring of Brucella melitensis using electrochemical impedance spectroscopy (EIS) is reported for the first time. The label-free immunosensors were fabricated by immobilizing Brucella melitensis antibody on the surface of gold nanoparticle-modified screen-printed carbon electrodes (GNP-SPCEs). Cyclic voltammetry (CV) and EIS were used to characteriz...
