background: a. bovis and a. phagocytophilium are leukocytotropic agents of bovine anaplasmosis. they are obligate intracellular bacteria that can infect and cause anaplasmosis in human and animals. therefore, this study was carried out to detect a. bovis and a. phagocytophilum in naturally infected dairy cattle in isfahan using molecular techniques. materials and methods: in this study a total ...

Streptococcus bovis HC5 produces a broad spectrum lantibiotic (bovicin HC5), but S. bovis JB1 does not have antimicrobial activity. Preliminary experiments revealed an anomaly. When S. bovis JB1 cells were washed in stationary phase S. bovis HC5 cell-free culture supernatant, the S. bovis JB1 cells were subsequently able to inhibit hyper-ammonia producing ruminal bacteria (Clostridium stickland...

A lipid-based formulation has been developed for oral delivery of Mycobacterium bovis bacille Calmette-Guérin (BCG) vaccine. The formulated M. bovis BCG was fed to BALB/c mice to test for immune responses and protection against M. bovis infection. The immune responses included antigen-specific cytokine responses, spleen cell proliferation, and lymphocyte-mediated macrophage inhibition of M. bov...

Deer movements on cattle farms, wildlife feeding, and livestock management practices in Michigan are thought to create opportunities for indirect transmission of Mycobacterium bovis via environmental substrates. To confirm the presence of viable M. bovis in the environment, substrates were collected from 13 farms with culture-confirmed M. bovis in cattle and 5 sites with high prevalence of M. b...

BACKGROUND Bovine tuberculosis, caused by Mycobacterium bovis, afflicts approximately 50 million cattle worldwide and is detected by the tuberculin skin test (TST). While it has long been recognized that purified protein derivative (PPD) tuberculin is composed of a mixture of M. bovis derived protein components, little is known about the quality, relative quantity and identity of the proteins t...

Mycobacterium bovis causes bovine tuberculosis and is the main organism responsible for zoonotic tuberculosis in humans. We performed the sequencing, assembly and annotation of a Brazilian strain of M. bovis named SP38, and performed comparative genomics of M. bovis genomes deposited in GenBank. M. bovis SP38 has a traditional tuberculous mycobacterium genome of 4,347,648 bp, with 65.5% GC, and...

bovine hypodermosis is a myiasis caused by larvae of hypoderma bovis and h. lineatum which are commonly known as grubs. as different insecticide pour-on treatments and sc ivermectin, which must be in direct contact with larvae, are used in larvae controlling programs, therefore, determining the exact topography of the most probable regions of larval presence is of great importance and it could ...

It has previously been shown that the PAN promoter from Mycobacterium paratuberculosis can be used as a DNA probe to identify an RFLP between wild-type Mycobacterium bovis and the vaccine strain Mycobacterium bovis BCG. To investigate the genetic basis of this phenomenon, DNA fragments from a New Zealand M. bovis cattle strain and M. bovis BCG Pasteur, containing the PAN-binding region, were is...

Bovine mastitis, caused by Prototheca bovis, has received much attention worldwide. To investigate the status of P. bovis infection in dairy farms Hubei, we collected 1,158 milk samples and 90 environmental from 14 China. The isolates were identified with traditional biological methods molecular techniques, their pathogenicity was tested through mice experiments. Isolates 57 20 as bovis. tests ...
