| isolation of a non-haemadsorbing, non-cytopathic strain of african swine fever virus in madagascar. | african swine fever (asf) suspected clinically in madagascar (1998-9) was confirmed by polymerase chain reaction (pcr) and nucleotide sequencing, following virus isolation. no haemadsorption or cytopathic effect could be detected following leukocyte inoculation, but viral growth in cells was confirmed by pcr. detection of asf virus genome was carried out by amplification of a highly conserved region coding for the p72 protein. nucleotide sequencing of the amplicon revealed 99.2% nucleotide ident ... | 2001 | 11467803 |
| ornithodoros porcinus ticks, bushpigs, and african swine fever in madagascar. | african swine fever (asf) has recently made its appearance in madagascar. ticks of the ornithodoros moubata group, considered to be o. porcinus walton, 1962 were formerly known to occur in western madagascar, but seem to have disappeared from that region. however, three new sites where they occur were found in the humid and cool central highlands of anatananarivo province. these ticks are known to be efficient reservoirs and vectors of asf and constitute a considerable complication to the contro ... | 2001 | 11523921 |
| an investigation into the first outbreak of african swine fever in the republic of mauritius. | outbreaks of african swine fever (asf) have been reported from many countries, particularly in sub-saharan africa, but until 2007 the disease had never been reported from the republic of mauritius. this is the first report describing field epidemiological and laboratory investigations into the outbreak of the lethal pig disease on the island. the official index case displayed clinical and necropsy signs suggestive of asf. serological and agent identification methods used to confirm and investiga ... | 2009 | 19432639 |
| assessment of interactions between african swine fever virus, bushpigs (potamochoerus larvatus), ornithodoros ticks and domestic pigs in north-western madagascar. | since its introduction in madagascar in 1998, african swine fever (asf) has severely affected national pig production and persists as a common disease in that country. two of its natural hosts in the african continent, the bushpig (potamochoerus larvatus) and tick vectors of the ornithodoros moubata complex, are reported in west and central regions of the island. however, their role in the maintenance and transmission of the virus has been insufficiently studied. in this work, we tried to assess ... | 2011 | 21320295 |
