Brucellosis is a worldwide zoonosis causing reproductive failures in livestock. It is shown that although the vaccine can prevent abortion, it does not provide complete protection against infection. So that vaccination of ewes with Rev.1 biotype can be a source of cattle and even human Brucellosis. The aim of this study was to evaluate possibility of Brucella cross-infection in cattle from Bruc...

INTRODUCTION Brucella spp. are gram-negative, facultative intracellular bacteria pathogens responsible for brucellosis, a zoonotic disease that can cause abortion, fetal death, and genital infections in animals and undulant fever in humans. Lipopolysaccharide (LPS) is known as a major virulence factor of Brucella spp. The wboA gene is capable of encoding a glycosyltransferase that appears to pl...

The seroprevalence of Brucella spp. and the possible associated risk factors were estimated for 2,109 adult cows in Monte Negro county, State of Rondônia, Brazil. A questionnaire was completed for each farm where cattle were sampled. Laboratory tests were Rose-Bengal Agglutination, Standard Tube agglutination, and Mercaptoethanol. The adjusted overall prevalence of Brucella spp. seropositive co...

A field study on the bacterial etiology of abortions among sheep and goats having migratory practices in the northwest hilly states of India was carried out. A total of 203 flocks were investigated. Abortion outbreaks occurred in 51 flocks and sporadic abortions occurred in 114 flocks. Vaginal swabs from aborted sheep and goats were collected and processed for isolation of bacterial agents from...

BACKGROUND The northern fur seal (Callorhinus ursinus) is an important cultural and nutritional resource for the Aleut community on St. Paul Island Alaska. In recent years, an increasing number of zoonotic pathogens have been identified in the population, but the public health significance of these findings is unknown. To determine the prevalence of Coxiella burnetii and Brucella spp. in northe...

Results differ as to whether Brucella infection during pregnancy increases a woman's risk of miscarriage. We determined the seroprevalence of BrucelIa spp. among a sample of women with miscarriage and women with no history of miscarriage in Jordan during January-July 2003. Serum samples were collected from 445 women with miscarriage and a similar number of women with no history of miscarriage, ...

Introduction Zoonotic diseases are an important cause of human morbidity and mortality; around 75% of recently emerging human infectious diseases are zoonoses. Herein we report the first seroprevalence study to include a range of emerging or re-emerging zoonotic pathogens of economic concern (including: Bacillus anthracis, Coxiella burnetii, Francisella spp., Brucella spp., and Crimean-Congo he...

Human brucellosis still presents scientists and clinicians with several challenges, such as the understanding of pathogenic mechanisms of Brucella spp, the identifi cation of markers for disease severity, progression, and treatment response, and the development of improved treatment regimens. Molecular studies have shed new light on the pathogenesis of Brucella spp, and new technologies have pe...

Routine disease surveillance has been conducted for decades in mule deer (Odocoileus hemionus) in California for pathogens shared between wildlife and domestic ruminants that may have implications for the animal production industry and wildlife health. Deer sampled from 1990 to 2007 (n = 2,619) were tested for exposure to six pathogens: bluetongue virus (BTV), epizootic hemorrhagic disease viru...
