Comparison of molecular techniques for the typing of Mycoplasma hyopneumoniae isolates.
discriminatory than RAPD (0.95) and estimation of the VNTR of P97 (<0.92). Other, preferentially well spread, tandem repeat regions should be included in order for this latter technique to become valuable for ...
Avian influenza: mini-review, European control measures and current situation in Asia.
contribute to the dissemination of the virus. In the context of H5N1, all movements (trade, high international mobility, migration and smuggling) can become high risk factors of spreading the disease. In most ...
Evaluation of the epidemiological importance of classical swine fever infected, E2 sub-unit marker vaccinated animals with RT-nPCR positive blood samples.
could be isolated by using the conventional virus isolation (VI) technique. To evaluate whether these vaccinated and infected pigs may spread the virus, three experiments were set up. In the first, ...
Transmission of classical swine fever. A review.
other animals in the spread of CSF virus remains doubtful. Active transmission by these has never been demonstrated and also very sparse indications for mechanical transmission are available. Also the ...
Risk analysis of the spread of classical swine fever virus through "neighbourhood infections" for different regions in Belgium.
technique. As a result, different areas in Belgium of higher or lower risk for CSF-virus spread through “neighbourhood infections” could be identified on the map. The areas in Belgium where CSF-outbreaks ...
Monitoring of pigeon paramyxovirus type-1 in organs of pigeons naturally infected with Salmonella Typhimurium.
observed. The spread of pPMV-1 was relatively quick, all organs being largely positive at 4 days after inoculation or contact. The lung, spleen, caecal tonsils, kidneys and brain, for which almost all tested ...
An experimental infection to investigate the indirect transmission of classical swine fever virus by excretions of infected pigs.
first 3 weeks of the experiment, the pens were neither cleaned nor disinfected. During the observation period, none of the susceptible pigs became infected. This result indicates that CSF virus spread via ...
Transmission of encephalomyocarditis virus (EMCV) among pigs experimentally quantified.
0.71 (95% CI =0.08-4.93). Combining the information from both experiments results in an estimate for R(0) of 1.24 (95% CI =0.39-4.35). Since R(0) has values around the threshold value of 1, the spread of ...
Classical swine fever (CSF) marker vaccine. Trial II. Challenge study in pregnant sows.
more potent as the estimated probability of fetal infections was lower. Nevertheless the risk of virus spreading after vaccination via transplacental transmission is still present and has to be addressed ...
An E2 sub-unit marker vaccine does not prevent horizontal or vertical transmission of classical swine fever virus.
protects pregnant gilts from the clinical course of the disease but does not prevent horizontal nor vertical spread of the CSF virus. Health Topics: Animal health Category: A1 FOS Classification: 4.03 ...
