Policies And Practices

With monetary support from the United States Department of Agriculture Foreign Agricultural Service (USDA FAS), an investigative effort was undertaken to document the biosecurity practices employed by commercial pig producers in Ukraine to prevent the introduction of African swine fever virus (ASFV) on their farms. The cohort of farms selected and evaluated were owned by producers who were active members of the Association of Ukrainian Pig Breeders (AUPB). The assessment of biosecurity policies and practices consisted of an interview and in-person completion of a questionnaire that evaluated various aspects of biosecurity practices used on pig farms in Ukraine. The results of the interviews and completion of survey questionnaires support the conclusion that Ukrainian pig producers recognize the importance of farm biosecurity as it relates to preventing ASFV introduction on their farms and all the participating farms had biosecurity policies that were in force at the time of completion of the questionnaire. However, the results also support the conclusion that significant gaps in understanding about biosecurity exists and that there is a need for more education of Ukrainian pig producers about this critical aspect of health management and disease control. The broad impact of the project detailed that prospective, more comprehensive work on Ukrainian pig farms is required to adequately assist producers with ASFV control and effective applications of biosecurity

Abstract BackgroundMosquitoes are important insect vectors, but whether they can carry and transmit African swine fever virus (ASFV) in large-scale pig farms in China is unknown. ResultsIn this study, probe qPCR analysis was performed on mosquitoes from five pig farms with ASF virus (ASFV). Analysis of ASFV in 463 mosquitoes yielded negative cycle threshold (CT) value), and detection remained negative after mixing samples from all five pig farms. ConclusionsTherefore, mosquitoes appear unlikely to transmit ASFV, and pose little threat to large-scale pig farms. Thus, farms should continue to follow normal mosquito control procedures when formulating strategies for the prevention and control of ASF.

Here, we report the complete genome sequence of the African swine fever virus (ASFV) isolate ASFV/Timor-Leste/2019/1, isolated from a domestic pig during the first outbreak of ASF in Timor-Leste in 2019. Using target enrichment short-read Illumina data combined with long-read Oxford Nanopore data, we assembled a full-length genome sequence of 192,237 bp.

SUMMARYTicks of the Ornithodoros moubata complex were collectedfrom domestic pig sties and dwelling houses, and from a warthog habitat, and tested for the presence of African swine fever (ASF) virus. Collections were made in 9 of the 24 districts of Malawi, these being primarily the districts in which O. moubata is most numerous. ASF virus was isolated from ticks collected in both domestic pig sties and houses in certain villages in Mchinji district where ASF outbreaks had recently occurred. Mchinji district is in the centre of a large ASF enzootic area which stretches into other districts of Malawi and also into Zambia and Mozambique. The high titre of virus in some of the ticks demonstrates that O. moubata can act as a virus reservoir and potential vector of disease in the field situation in Malawi.

ABSTRACT This study reports the genome sequence of an isolated African swine fever (ASF) virus (VNUA-ASFV-05L1/HaNam) obtained at the fourth passage on pulmonary alveolar macrophages. The virus was isolated during a typical acute ASF outbreak in pigs in a northern province of Vietnam in 2020.

SUMMARYA detailed study was made in 1983–5 in three villages in Mehinji district in the African swine fever (ASF) enzootic area of Malawi, following an outbreak of ASF which affected all three villages.Ticks of the Ornithodoros moubata complex were collected from both pig sties and houses shortly after the outbreak, and approximately 24% contained ASF virus. The proportion of ticks infected did not differ significantly in the three villages, or more surprisingly in different types of premises, and was equivalent in all stages of ticks. The proportion infected decreased with the passage of time, but infected ticks were still present in all three villages 8 months after the outbreak, some with high titres of virus.The proportion of seropositive pigs in the three villages approached 100% following the outbreak, with many apparently healthy pigs being seropositive. It is suggested that Malawian isolates of ASF virus may be less virulent in African than European breeds of domestic pig.
