Anaplasma bovis is a leukocytotropic agent of bovine anaplasmosis and there is no available information about molecular study on this agent in cattle of Iran. In this study a total 150 cattle blood samples were collected from central part of Iran. The presence of A. bovis examined using light microscopic detection and species-specific nested polymerase chain reaction (nested-PCR) based on 16S r...
Bovine tuberculosis (BTB), a zoonotic infection of cattle caused by Mycobacterium bovis, results in losses of $3 billion to the global agricultural industry and represents the fourth most important livestock disease worldwide. M. bovis as a source of human infection is likely underreported due to the culture medium conditions used to isolate the organism from sputum or other sample sources. We ...
The purpose of this study was to determine the antibacterial susceptibility of field isolates of Mycoplasma bovis originating from the upper respiratory tract of cattle of different ages. Bacteriological examination of 90 nasal swabs collected from calves at three months of age identified M. bovis in 31 (34.44%) samples. Seventeen (18.88%) of these animals still housed M. bovis in their nasal c...
BACKGROUND In many regions of the world, wild mammals act as reservoir of Mycobacterium bovis, a situation that prevents the eradication of bovine tuberculosis. In order to observe whether a strain isolated from a wild boar, previously tested as highly virulent in a mice model, is also virulent in cattle, we performed cattle experimental inoculation with this strain RESULTS Groups of Friesian...
Bovine tuberculosis is a zoonotic disease with largely unknown impact in Africa, with risk factors such as HIV and direct contact with animals or consumption of Mycobacterium bovis infected animal products. In order to understand and quantify this risk and design intervention strategies, good epidemiological studies are needed. Such studies can include molecular typing of M. bovis isolates. The...
Mycoplasma spp. are contagious bacteria, and mycoplasmal mastitis is a serious productivity problem on dairy farms. Bovine mammary epithelial cells (bMECs) have an important role in the elimination of pathogens, but the effect of Mycoplasma bovis on bMECs has not been fully described. To elucidate the immune response against intramammary infection by M. bovis, we undertook microarray analysis t...
Mycobacterium bovis is the causative agent of tuberculosis in a range of animal species and man, with worldwide annual losses to agriculture of $3 billion. The human burden of tuberculosis caused by the bovine tubercle bacillus is still largely unknown. M. bovis was also the progenitor for the M. bovis bacillus Calmette-Guérin vaccine strain, the most widely used human vaccine. Here we describe...
Recent studies indicate that interleukin 8 (IL-8) production contributes to the host immune responses against mycobacterial infection. In this study, we were interested to determine whether induction of IL-8 in human monocytes infected with Mycobacterium bovis was regulated by other monocyte-derived cytokines important in antimycobacterial immunity: IL-10 and transforming growth factor beta (TG...
Mycobacterium bovis strains isolated from tuberculosis (TB) lesions from 1138 cattle slaughtered at Kombolcha abattoir in north eastern Ethiopia were characterised. Detailed postmortem examination, bacteriological culturing, regions of difference PCR and spoligotyping were used. At least one TB lesion was observed in 57 (5 per cent) of the cattle, of which 27 (47 per cent) yielded mycobacteria ...
The availability of a stage-specific Babesia bovis expression profile can facilitate the identification of candidate vaccine antigens. In addition, highly expressed genes during a particular developmental stage may suggest their relevance during that stage. In this study, we generated and validated a custom B. bovis high density oligonucleotide microarray that can be used to examine gene expres...
