Identification of encephalomyocarditis virus in clinical samples by reverse transcription-PCR followed by genetic typing using sequence analysis.
of the gene which encodes the viral polymerase was assessed with experimental and field samples. In addition, the use of the amplified sequences for an epidemiological study was evaluated. The heart ...
An experimental infection with classical swine fever virus in weaner pigs. I. Transmission of the virus, course of the disease, and antibody response.
isolated in the first CSF infected herd of the 1993-1994 Belgian epizootic, was examined in an isolation unit with three adjacent pens and 15 weaner pigs per pen. Virus was introduced through experimental ...
An experimental infection with a classical swine fever virus in weaner pigs. II. The use of serological data to estimate the day of virus introduction in natural outbreaks.
a companion paper a logistic regression model of seroprevalence over time was developed on the basis of data obtained during an experimental infection of weaner pigs with classical swine fever (CSF) virus. The ...

Induction of cytotoxic T-cell responses against culture filtrate antigens in Mycobacterium bovis bacillus Calmette-Guérin-infected mice.
mycobacteria, as is clearly demonstrated by the fatal outcome of experimental infection of beta-2 microglobulin knockout mice. However, the mechanisms and antigens (Ags) leading to CD8 + T-cell activation and ...
Specific interferon-gamma, IgA and IgM responses after experimental infection of neonatal calves with Cryptosporidium parvum.
production by peripheral blood mononuclear cells and the local antibody build up was monitored in neonatal calves experimentally infected with Cryptosporidium parvum and in negative controls of the same age. ...
Reproductive failure in sows following experimental infection with a Belgian EMCV isolate.
One month after birth EMCV could be isolated from all the piglets examined. These results can help in a better understanding of the spread of the disease in piggeries. Health Topics: Animal health ...

Specific serum and local antibody responses against Cryptosporidium parvum during medication of calves with halofuginone lactate.
oocysts from 0 to 21 days. Medication stopped oocyst output at day 7, but some of the calves again passed low numbers of oocysts 7 days after withdrawal of the drug. Experimental infection of unmedicated ...
Identification of eae sequences in enteropathogenic Escherichia coli strains from rabbits.
enteropathogenic Escherichia coli strains from rabbits. All of the strains produced diarrhea after experimental infection, attached to the brush borders of the intestinal lining, and possessed homology to the eae ...
