Brucellosis is one of the most common zoonotic epidemics worldwide. Brucella, the etiological pathogen of brucellosis, has unique virulence characteristics, including the ability to survive within the host cell. Hfq is a bacterial chaperone protein that is involved in the survival of the pathogen under stress conditions. Moreover, hfq affects the expression of a large number of target genes. In...
Brucella pinnipedialis was first isolated from true seals in 1994 and from eared seals in 2008. Although few pathological findings have been associated with infection in true seals, reproductive pathology including abortions, and the isolation of the zoonotic strain type 27 have been documented in eared seals. In this study, a Brucella enzyme-linked immunosorbent assay (ELISA) and the Rose Beng...
A comparative study was conducted using data from naive bison (n = 45) and cattle (n = 46) from 8 and 6 studies, respectively, in which a standardized Brucella abortus strain 2308 experimental challenge was administered during midgestation. The incidence of abortion, fetal infection, uterine or mammary infection, or infection in maternal tissues after experimental challenge was greater (P < 0.0...
Brucellosis caused by Brucella spp. is a major zoonotic disease. Control of brucellosis in agricultural animals is a prerequisite for the prevention of this disease in human beings. Recently, Brucella melitensis was declared by the Centers for Disease Control and Prevention to be one of three major bioterrorist agents due to the expense required for the treatment of human brucellosis patients. ...
1. Comparison of the infections of chick embryos by the chorio-allantoic route indicates that Bacterium tularense and Brucella suis, abortus, and melitensis exhibit varying degrees of facultative intracellular parasitism. Pasteurella pestis is adapted to rapid proliferation and spread in the intercellular fluids. 2. In the early stages of infection Bacterium tularense has a marked affinity for ...
Brucella canis infection can be clinically inapparent in dogs, and when infection goes unnoticed, there is a chance for dog-to-human transmission. A new strain of B. canis was isolated from the blood of an infected dog in order to analyze the pathogenic mechanism, compare genetic properties, and develop new genetic tools for early diagnosis of canine brucellosis. Herein, we report the complete ...
The microslide gel-diffusion and macro-tube agglutination techniques to detect Brucella canis antibodies in dogs were compared. Sera from dogs experimentally infected with B. canis and a random sample of dog sera with unknown histories of exposure to this organism were examined. The results of the gel-diffusion method employing specific rough Brucella saline-extract antigens of B. canis and Bru...
Brucella melitensis causes the most severe and acute symptoms of all Brucella species in human beings and infects hosts primarily through the oral route. The epithelium covering domed villi of jejunal-ileal Peyer's patches is an important site of entry for several pathogens, including Brucella. Here, we use the calf ligated ileal loop model to study temporal in vivo Brucella-infected host molec...
OBJECTIVE Brucella endocarditis is a rare complication of Brucella infection; however, it is the major cause of deaths in those infected with this disease. In this study, we aim to discuss the results of seven cases who underwent surgery for Brucella endocarditis in our clinic using the knowledge gathered through the literature. METHODS We reviewed seven patients with Brucella endocarditis, w...
Brucella abortus and polyacrylic acid, two agents whose interferon-inducing capacity in the mouse has been well established, failed to stimulate circulating interferon production in rabbits, yet protected rabbits against local vaccinia virus infection.
