A lipid modified ubiquitin is packaged into particles of several enveloped viruses. (1/269)

An anti-ubiquitin cross-reactive protein which migrates more slowly (6.5 kDa) by SDS-PAGE than ubiquitin was identified in African swine fever virus particles. This protein was extracted into the detergent phase in Triton X-114 phase separations, showing that it is hydrophobic, and was radiolabelled with both [3H]palmitic acid and [32P]orthophosphate. This indicates that the protein has a similar structure to the membrane associated phosphatidyl ubiquitin described in baculovirus particles. A similar molecule was found in vaccinia virus and herpes simplex virus particles, suggesting that it may be a component of uninfected cell membranes, which is incorporated into membrane layers in virions during morphogenesis.  (+info)

Nuclear and nucleolar localization of an African swine fever virus protein, I14L, that is similar to the herpes simplex virus-encoded virulence factor ICP34.5. (2/269)

PCR analysis of the genomes of 18 different African swine fever virus (ASFV) isolates showed that the I14L open reading frame (ORF) was present as either a long form or short form in all of the isolates. Sequencing of the ORF from eight isolates confirmed that both forms of the ORF were well conserved. Antisera raised against the I14L protein identified the long form of the protein as a 21 kDa protein expressed late during ASFV infection. Immunofluorescent analysis of transiently expressed haemagglutinin-tagged forms of the I14L protein showed that the long form of the protein localized predominantly to the nucleus and within the nucleoli. In contrast, although the short form of the protein was also present predominantly in the nucleus, it did not localize to the nucleoli. Deletion of the N-terminal 14 amino acids from the long form of the I14L protein, which includes a high proportion of basic Arg/Lys residues, abolished the specific nucleolar localization of the protein, although the protein was still present in the nucleus. Addition of this 14 amino acid sequence to beta-galactosidase or replacement of the N-terminal 14 amino acids of the I14L short form with those from the long form directed both of these modified proteins to the nucleolus. This indicates that this 14 amino acid sequence contains all the signals required for nucleolar localization.  (+info)

Modulation of monocytic cell activity and virus susceptibility during differentiation into macrophages. (3/269)

A major component of innate immune responses relies on monocytes and macrophages, virus infection of which will pose a particular problem for immunological defense. Consequently, the monocytic cell differentiation pathway was analyzed in terms of cellular modulations therein and their relation to monocytotropic virus infection. Differentiation was characterized by down-regulation of CD14, MHC Ags, the monocytic SWC1 marker, and p53; concomitant up-regulation of the SWC9 macrophage marker, a putative porcine CD80 (detected with anti-human CD80 Ab), and acid phosphatase secretion were also characteristic. Elevated phagocytic and endocytic activities as well as endosomal/lysosomal acidification were identified as being important to the macrophage. In contrast, monocytes possessed high accessory activity. This was multifactorial, concomitantly requiring 1) high MHC Ag expression; 2) enzyme activity of esterase, peroxidase, myeloperoxidase, and 5' nucleotidase in preference to glucosidase, galactosidase, and glucuronidase; and 3) elevated capacity for spontaneous IL-1 production. Only with all parameters was efficient stimulation of Ag-specific lymphocytes possible. These results point to a continuous process during differentiation, involving inter-related characteristics linking the more accessory monocyte to the scavenger macrophage, both in vitro and in vivo. Of particular interest was how these characteristics related to monocytotropic virus infection, and how a particular virus could show a clear preference for the differentiating macrophages. Such results not only further our understanding of porcine immunology, but also provide evidence and a potential model for the determination and characterization of monocytotropic virus-host cell interactions.  (+info)

The biological effects induced in mice by p36, a proteinaceous factor of virulence produced by African swine fever virus, are mediated by interleukin-4 and also to a lesser extent by interleukin-10. (4/269)

We have previously presented indirect evidence that both specific immunosuppression and lymphocyte mitogenicity induced in mice by p36, a proteinaceous factor of virulence produced by porcine monocytes infected by African swine fever virus, were consistent with a Th2-driven response. Here we show: (1) Interleukin-4 (IL-4) and interleukin-10 (IL-10) mRNA expression in the spleen and thymus of C57BL/6 mice were displayed early after p36 inoculation. The expression of thymic IL-10 mRNA occurred, however, later than that of IL-4 mRNA. (2) Increased serum levels of these two cytokines were also soon detected after the protein inoculation. (3) Both immunosuppressive and mitogenic effects of p36 were absent in IL-4 gene-targeted mice and partially abrogated in mice depleted of IL-4 by neutralizing monoclonal antibodies. (4) IL-10 depletion abrogated the immunosuppressive but not the p36 lymphocyte mitogenic biological effects. (5) The increase in the serum concentrations of both IL-4 and IL-10 were lower in thymectomized than in non-thymectomized mice. (6) The expression of interferon-gamma (IFN-gamma) mRNA was weakly or not at all induced in p36-treated mice. Taken together, these results are in agreement with the promotion of a Th2 immune response induced by p36.  (+info)

Replication of African swine fever virus DNA in infected cells. (5/269)

We have examined the ultrastructural localization of African swine fever virus DNA in thin-sections of infected cells by in situ hybridization and autoradiography. Virus-specific DNA sequences were found in the nucleus of infected Vero cells at early times in the synthesis of the viral DNA, forming dense foci localized in proximity to the nuclear membrane. At later times, the viral DNA was found exclusively in the cytoplasm. Electron microscopic autoradiography of African swine fever virus-infected macrophages showed that the nucleus is also a site of viral DNA replication at early times. These results provide further evidence of the existence of nuclear and cytoplasmic stages in the synthesis of African swine fever virus DNA. On the other hand, alkaline sucrose sedimentation analysis of the replicative intermediates synthesized in the nucleus and cytoplasm of infected macrophages showed that small DNA fragments ( approximately 6-12S) were synthesized in the nucleus at an early time, whereas at later times, larger fragments of approximately 37-49S were labeled in the cytoplasm. Pulse-chase experiments demonstrated that these fragments are precursors of the mature cross-linked viral DNA. The formation of dimeric concatemers, which are predominantly head-to-head linked, was observed by pulsed-field electrophoresis and restriction enzyme analysis at intermediate and late times in the replication of African swine fever virus DNA. Our findings suggest that the replication of African swine fever virus DNA proceeds by a de novo start mechanism with the synthesis of small DNA fragments, which are then converted into larger size molecules. Ligation or further elongation of these molecules would originate a two-unit concatemer with dimeric ends that could be resolved to generate the genomic DNA by site-specific nicking, rearrangement, and ligation as has been proposed in the de novo start model of Baroudy et al. (B. M. Baroudy, S. Venkatesam, and B. Moss, 1982, Cold Spring Harbor Symp. Quant. Biol. 47, 723-729) for the replication of vaccinia virus DNA.  (+info)

The African swine fever virus prenyltransferase is an integral membrane trans-geranylgeranyl-diphosphate synthase. (6/269)

In a previous study, it was shown that the protein encoded by the gene B318L of African swine fever virus (ASFV) is a trans-prenyltransferase that catalyzes in vitro the condensation of farnesyl diphosphate and isopentenyl diphosphate to synthesize geranylgeranyl diphosphate and longer chain prenyl diphosphates (Alejo, A., Yanez, R. J., Rodriguez, J. M., Vinuela, E., and Salas, M. L. (1997) J. Biol. Chem. 272, 9417-9423). To investigate the in vivo function of the viral enzyme, we have determined, in this work, its subcellular localization and activity in cell extracts. Two systems were used in these studies: cells infected with ASFV and cells infected with a recombinant pseudo-Sindbis virus carrying the complete B318L gene. In this latter system, the trans-prenyltransferase was found to colocalize with the endoplasmic reticulum marker protein-disulfide isomerase, whereas in cells infected with ASFV, the viral enzyme was present in cytoplasmic viral assembly sites, associated with precursor viral membranes derived from the endoplasmic reticulum. In addition, after subcellular fractionation, the viral enzyme partitioned into the membrane fraction. Extraction of membrane proteins with alkaline carbonate and Triton X-114 indicated that the ASFV enzyme behaved as an integral membrane protein. The membrane enzyme synthesized predominantly all-trans-geranylgeranyl diphosphate from farnesyl diphosphate and isopentenyl diphosphate. These results indicate that the viral B318L protein is a trans-geranylgeranyl-diphosphate synthase, being the only enzyme of this type that is known to have a membrane localization.  (+info)

African swine fever virus: a B cell-mitogenic virus in vivo and in vitro. (7/269)

The two major characteristics of pathogenesis in African swine fever virus (ASFV) infections of domestic pigs are massive B-cell apoptosis and haemorrhage. The effects of ASFV on porcine B cells have therefore been systematically examined in vivo, by using virus-infected pigs and SCID-Beige mice reconstituted with porcine bone marrow, and in vitro, by using porcine B-cell lines and B cells from normal and ASFV-infected pigs. Secretion of porcine Ig was stimulated by ASFV both in vivo and in bone marrow cultures in vitro, with the virulent Malawi isolate of ASFV being the most effective. Stimulation of Ig secretion in vitro depended on the presence of ASFV-infected macrophages and did not occur with supernatants from ASFV-infected macrophages. Although the virus alone did not stimulate proliferation of purified B cells in vitro, it was co-stimulatory with CD154 (CD40 ligand). The B cells recovered from ASFV-infected porcine lymphoid tissue were of activated surface marker phenotypes and, interestingly, expressed diminished levels of the B-cell co-stimulatory surface molecule CD21. In addition, they were highly sensitive to IL-4 and CD154. These results may be integrated into a model of pathogenesis in which those B cells activated indirectly as a result of virulent ASFV infection of macrophages are not rescued from apoptosis through interaction with CD154, due to the drastic depletion of T cells that occurs early in infection. The consequently diminished specific anti-ASFV antibody response would favour survival of the virus, with the non-specific hypergammaglobulinaemia being perhaps another example of pathogen-mediated immune deviation.  (+info)

African swine fever virus replication in the midgut epithelium is required for infection of Ornithodoros ticks. (8/269)

Although the Malawi Lil20/1 (MAL) strain of African swine fever virus (ASFV) was isolated from Ornithodoros sp. ticks, our attempts to experimentally infect ticks by feeding them this strain failed. Ten different collections of Ornithodorus porcinus porcinus ticks and one collection of O. porcinus domesticus ticks were orally exposed to a high titer of MAL. At 3 weeks postinoculation (p.i.), <25% of the ticks contained detectable virus, with viral titers of <4 log(10) 50% hemadsorbing doses/ml. Viral titers declined to undetectability in >90% of the ticks by 5 weeks p.i. To further study the growth defect, O. porcinus porcinus ticks were orally exposed to MAL and assayed at regular intervals p.i. Whole-tick viral titers dramatically declined (>1,000-fold) between 2 and 6 days p.i., and by 18 days p.i., viral titers were below the detection limit. In contrast, viral titers of ticks orally exposed to a tick-competent ASFV isolate, Pretoriuskop/96/4/1 (Pr4), increased 10-fold by 10 days p.i. and 50-fold by 14 days p.i. Early viral gene expression, but not extensive late gene expression or viral DNA synthesis, was detected in the midguts of ticks orally exposed to MAL. Ultrastructural analysis demonstrated that progeny virus was rarely present in ticks orally exposed to MAL and, when present, was associated with extensive cytopathology of phagocytic midgut epithelial cells. To determine if viral replication was restricted only in the midgut epithelium, parenteral inoculations into the hemocoel were performed. With inoculation by this route, a persistent infection was established although a delay in generalization of MAL was detected and viral titers in most tissues were typically 10- to 1,000-fold lower than those of ticks injected with Pr4. MAL was detected in both the salivary secretion and coxal fluid following feeding but less frequently and at a lower titer compared to Pr4. Transovarial transmission of MAL was not detected after two gonotrophic cycles. Ultrastructural analysis demonstrated that, when injected, MAL replicated in a number of cell types but failed to replicate in midgut epithelial cells. In contrast, ticks injected with Pr4 had replicating virus in midgut epithelial cells. Together, these results indicate that MAL replication is restricted in midgut epithelial cells. This finding demonstrates the importance of viral replication in the midgut for successful ASFV infection of the arthropod host.  (+info)

African swine fever is a devastating hemorrhagic fever of pigs, caused by the African swine fever virus (ASFV). In Africa, the presence of a sylvatic cycle involving warthogs and soft ticks means that the risk of introduction of ASFV into domestic swine is always present. Bushpigs (Potamochoerus larvatus) are nocturnal, susceptible to ASFV and share a natural interface with both warthogs and domestic pigs. The role of the bushpig in the epidemiology of ASFV if any is not understood, yet control strategies of the disease in areas with probable contact between bushpigs and domestic pigs would depend on such information. This study used a molecular and ecological approach to investigate the role of the bushpig in the epidemiology of African swine fever at the wildlife-livestock interface in Uganda. The GPS/GSM tracking collars were used to monitor the movement patterns of free-ranging domestic pigs and bushpigs. Four free-ranging domestic pigs and five bushpigs were collared and their movements ...

The role of the ancestral sylvatic cycle of the African swine fever virus (ASFV) is not well understood in the endemic areas of eastern Africa. We therefore analysed the ASF infection status on samples collected from 51 free-ranging warthogs (Phacocherus africanus) and 1576 Ornithodorus porcinus ticks from 26 independent warthog burrows at a single ranch in Kenya. Abattoir samples from 83 domestic pigs without clinical symptoms, originating from specific locations with no recent reported ASF outbreaks were included in this study. All samples were derived from areas of central Kenya, where ASF outbreaks have been reported in the past. Infection with ASFV was confirmed in 22% of O. porcinus pools, 3.22% of adult warthog serum samples and 49% of domestic pig serum samples by using p72-based PCR. All of the warthog sera were positive for anti-ASFV antibodies, investigated by using ELISA, but none of the domestic pig sera were positive. Twenty O. porcinus-, 12 domestic pig- and three warthogderived ...

Rigid amphipathic fusion inhibitors demonstrate antiviral activity against African swine fever virus | Microbiology SocietyRigid amphipathic fusion inhibitors demonstrate antiviral activity against African swine fever virus | Microbiology Society
Rigid amphipathic fusion inhibitors (RAFIs) are a family of nucleoside derivatives that inhibit the infectivity of several enveloped viruses by interacting with virion envelope lipids and inhibiting fusion between viral and cellular membranes. Here we tested the antiviral activity of two RAFIs, 5-(Perylen-3-ylethynyl)-arabino-uridine (aUY11) and 5-(Perylen-3-ylethynyl)uracil-1-acetic acid (cm1UY11) against African swine fever virus (ASFV), for which no effective vaccine is available. Both compounds displayed a potent, dose-dependent inhibitory effect on ASFV infection in Vero cells. The major antiviral effect was observed when aUY11 and cm1UY11 were added at early stages of infection and maintained during the complete viral cycle. Furthermore, virucidal assay revealed a significant extracellular anti-ASFV activity for both compounds. We also found decrease in the synthesis of early and late viral proteins in Vero cells treated with cm1UY11. Finally, the inhibitory effect of aUY11 and cm1UY11 on ASFV

African swine fever | ari.info | ari.infoAfrican swine fever | ari.info | ari.info
African swine fever. African swine fever (ASF) is a highly contagious hemorrhagic disease of pigs that produces a wide range of clinical signs and lesions that closely resemble those of classical swine fever. Infection, with a highly variable virulence, causes, typically 3-15 days later, high fever, reddening of the skin (visible only in pale-skinned pigs), decreased appetite, listlessness, loss of coordination, vomiting, diarrhoea (sometimes bloody) and eye discharges. Mortality rates can be as high as 100% in domestic pigs and wild boar, with death occurring in less than a week. In some cases, sudden death may be the only clinical sign.. The disease was first described after European settlers brought pigs into areas endemic with ASFV and, as such, is an example of an emerging infection. Although ASFV can be adapted to grow in cells from different species, it does not replicate readily in any species other than swine. Fortunately, African swine fever is not a human health threat.. The virus : ...

We describe a horizontal survey of African swine fever virus (ASFV) prevalence and risk factors associated with virus infection in domestic pigs in two contrasting production systems in Kenya. A free range/tethering, low input production system in Ndhiwa District of South-western Kenya is compared with a medium input stall fed production system in Kiambu District of Central Kenya. Analysis of variance (ANOVA) of data derived from cluster analysis showed that number of animals, number of breeding sows and number of weaner pigs were a significant factor in classifying farms in Nhiwa and Kiambu. Analysis of blood and serum samples using a PCR assay demonstrated an average animal level positivity to ASFV of 28% in two independent samplings in South-western Kenya and 0% PCR positivity in Central Kenya. No animals were sero-positive in either study site using the OIE indirect-ELISA and none of the animals sampled exhibited clinical symptoms of ASF. The farms that contained ASFV positive pigs in Ndhiwa ...

South Korea on highest alert after African swine fever found - InteraksyonSouth Korea on highest alert after African swine fever found - Interaksyon
African swine fever is highly contagious and nearly 100% fatal to swine herds. It occurs among pigs and wild boars, transmitted by ticks and direct contact between animals. There is no vaccine for the disease, but it does not affect humans.. The first outbreak of African swine fever in East Asia was reported in China in early August 2018. Since then, the deadly virus has spread to all Chinese provinces and regions, as well as to other Asian nations, including Vietnam and the Philippines.. South Korea, Asias fourth-largest economy, does not import any pork products or live pigs from China due to Chinas history of foot-and-mouth disease outbreaks. It mainly imports from the United States and Germany, and pork imports account for about a third of the countrys total pork supplies.. Although this is the first time African swine fever has hit South Korea, an incidence of foot-and-mouth disease was confirmed in March 2018 at a hog farm, the countrys first discovery since February 2017..

CRISPR/Cas Gene Editing of a Large DNA Virus: African Swine ...CRISPR/Cas Gene Editing of a Large DNA Virus: African Swine ...
Gene editing of large DNA viruses, such as African swine fever virus (ASFV), has traditionally relied on homologous recombination of a donor plasmid consisting of a reporter cassette with surrounding homologous viral DNA. However, this homologous recombination resulting in the desired modified virus is a rare event. We recently reported the use of CRISPR/Cas9 to edit ASFV. The use of CRISPR/Cas9 to modify the African swine fever virus genome resulted in a fast and relatively easy way to introduce genetic changes. To accomplish this goal we first infect primary swine macrophages with a field isolate, ASFV-G, and transfect with the CRISPR/Cas9 donor plasmid along with a plasmid that will express a specific gRNA that targets our gene to be deleted. By inserting a reporter cassette, we are then able to purify our recombinant virus from the parental by limiting dilution and plaque purification. We previously reported comparing the traditional homologous recombination methodology with CRISPR/Cas9, which

We applied social network analysis to pig trader networks on the Kenya-Uganda border. Social network analysis is a recently developed tool, which is useful for understanding value chains and improving disease control policies. We interviewed a sample of 33 traders about their experiences with trade and African swine fever (ASF), analyzed the networks they generated in purchasing pigs and selling pork and their potential contribution to modulating dissemination of the ASF virus (ASFV). The majority of the traders were aware of clinical signs of ASF and the risk of trade transmitting ASFV. Most said they avoided buying pigs from ASF outbreak villages or sick pigs but their experiences also indicated that inadvertent purchase was relatively common. Traders had early knowledge of outbreaks since they were contacted by farmers who had heard rumours and wanted to sell their pigs to avoid the risk of them dying. Individual traders bought pigs in up to nine villages, and up to six traders operated in a ...

Global efforts sought to curb African swine fever - Seal News LEADING ORIENTALGlobal efforts sought to curb African swine fever - Seal News LEADING ORIENTAL
The World Organization for Animal Health, or OIE, and the Food and Agriculture Organization, or FAO, have called on countries and partners to join forces against African swine fever, which has become a major crisis for the pork industry.. The organizations said the fever is causing massive losses in pig populations and generating drastic economic consequences. Pork is the most consumed meat in the world, representing 36 percent of global meat consumption.. On a global scale, they said the sustained spread of the fever poses a threat to food security, economic and rural development.. The organizations said the disease represents a barrier to the agricultural sector to reach its full potential, generate employment and alleviate poverty, and acts as a disincentive to investment in the sector.. Global control of African swine fever will thus contribute to achieving the United Nations Sustainable Development Goals, notably goal one which seeks to alleviate poverty and goal two that seeks achievement ...

New Swine Fever Virus Affecting Chinese Herds | Hoosier Ag TodayNew Swine Fever Virus Affecting Chinese Herds | Hoosier Ag Today
Industry insiders tell Reuters that a new form of African swine fever is popping up on Chinese pig farms. The timing is not good for the worlds biggest pork producer thats still trying to recover from a devastating epidemic.. Two new strains of African Swine Fever have infected over 1,000 sows on several farms owned by Chinas fourth-largest pork producer. Its also showing up in pigs being fattened for the firm by contract farmers.. A company spokesperson says the disease isnt quite the same as the wild African Swine Fever Virus because the new variant doesnt kill the large number of pigs that China lost in 2018 and 2019. The new strain causes a chronic condition that reduces the number of healthy piglets born to sows. But infected pigs are culled from herds to prevent the spread, which makes the disease ultimately fatal.. Many Chinese farmers turned to unapproved products to help protect their animals. Chinese experts fear the illicit vaccines created accidental infections that have begun ...

Molecular monitoring of African swine fever control areas: adult-tick by L. F. Arnot, J. T. du Toit et al.Molecular monitoring of African swine fever control areas: adult-tick by L. F. Arnot, J. T. du Toit et al.
The Mkuze Game Reserve (MGR), in north-eastern KwaZulu-Natal Province, South Africa is an African swine fever virus (ASF) controlled area. In a survey conducted in 1978, ASF prevalence in warthogs and Ornithodoros ticks in MGR was determined to be 2% and 0.06%, respectively. These values, acknowledged as being unusually low compared to other East and southern African ASF-positive sylvatic-cycle host populations, have not been assessed since. The availability of a sensitive PCR-based virus detection method, developed specifically for the sylvatic tampan host, prompted a re-evaluation of ASF virus (ASFV) prevalence in MGR ticks. Of the 98 warthog burrows inspected for Ornithodoros presence, 59 (60.2%) were found to contain tampans and tick sampling was significantly male-biased. Whilst gender sampling-bias is not unusual, the 27% increase in infestation rate of warthog burrows since the 1978 survey is noteworthy as it anticipates a concomitant increase in ASFV prevalence, particularly in light of the high

The pathogenesis of African swine fever in the resistant bushpig. | Microbiology SocietyThe pathogenesis of African swine fever in the resistant bushpig. | Microbiology Society
Bushpigs and warthogs are natural reservoir hosts of African swine fever virus (ASFV) in the wild, showing no clinical signs of disease when infected with the same highly virulent isolates of ASFV that induce rapid, haemorrhagic death in domestic pigs. In contrast to domestic pigs, infection of bushpigs with Malawi isolate results in low levels of virus replication and lymphocyte apoptosis within the spleen, and a relatively low spread of virus to other lymphoid tissues. However, at 10 days post-infection, a high degree of apoptosis was seen in B lymphocytes of the B cell follicles in bushpig lymph nodes. Virus infected cells were present amongst the apoptotic B cells of these follicles, suggesting that indirect factors released from ASFV infected macrophages signal surrounding lymphocytes to enter apoptosis. The susceptibility/resistance of domestic pigs/bushpigs to ASFV may serve as a unique veterinary model for the recently emerging haemorrhagic disease of man.

African swine fever prompts cancellation of World Pork Expo - Country FolksAfrican swine fever prompts cancellation of World Pork Expo - Country Folks
by Stephen Wagner. The National Pork Producers Councils board of directors has announced its decision to cancel the 2019 World Pork Expo in Iowa out of an abundance of caution as African swine fever (ASF) continues to spread in China and other parts of Asia. The World Pork Expo, held each June at the Iowa State Fairgrounds in Des Moines, hosts approximately 20,000 visitors over three days, including individuals and exhibitors from ASF-positive regions. ASF affects only pigs and presents no human health or food safety risks. There is currently no vaccine to treat the swine disease.. The above paragraph came from a recent press release issued by the NPPC, and was forwarded to me by Penn-Ag Industries Assistant Vice President Jessica Darr. While attending Penn-Ags annual meeting, Darr, and Debbie Reed-Harry, casually mentioned ASF, something I was hearing about for the first time. How serious is this? I asked.. We talk about it every day, Darr said.. When I got home I began a file on it, and ...

Abstract: A training and outreach program to increase public awareness of African swine fever (ASF) was implemented by DTRA and the Ministries of Agriculture in Armenia, Georgia, Kazakhstan, and Ukraine. The implementing agency was the company SAFOSO (Switzerland). Integration of this regional effort was administered by subject matter experts for each country. The main teaching effort of this project was to develop a comprehensive regional public outreach campaign through a network of expertise and knowledge for the control and prevention of ASF in four neighboring countries that experience similar issues with this disease. Gaps in disease knowledge, legislation, and outbreak preparedness in each country were all addressed. Because ASF is a pathogen with bioterrorism potential and of great veterinary health importance that is responsible for major economic instability, the project team developed public outreach programs to train veterinarians in the partner countries to accurately and rapidly

African swine fever spreading slowly, says reportAfrican swine fever spreading slowly, says report
African swine fever is spreading slowly in the Baltic countries and Poland, according to the latest epidemiological data analysed by these Member States and EFSA.. The disease is spreading at about 2 km a month in Latvia and Estonia, and 1 km a month in Lithuania and Poland. In addition, the number of infected animals found among hunted wild boar is very low (up to 3%). The outbreaks in wild boar in the Baltic countries and Poland can therefore be defined as a small-scale epidemic.. The report covers cases reported between 2014 and 2016.. This report is the outcome of a fruitful cooperation with Member States. We look forward to continuing investigations on this disease, which has serious socio-economic consequences in affected countries, says Andrea Gervelmeyer, veterinary epidemiologist at EFSA..

USDA APHIS | APHIS adds Moldova to the List of Regions Affected by African Swine FeverUSDA APHIS | APHIS adds Moldova to the List of Regions Affected by African Swine Fever
The U.S. Department of Agricultures (USDA) Animal and Plant Health Inspection Service (APHIS) added Moldova to a list of regions considered affected with African swine fever (ASF). We are taking this action because of the confirmation of ASF in Moldova. ASF is a highly contagious disease of wild and domestic swine that can spread rapidly in swine populations with extremely high rates of morbidity and mortality. A list of regions where ASF exists or is reasonably believed to exist is maintained on the APHIS Web site at https://www.aphis.usda.gov/aphis/ourfocus/animalhealth/animal-and-animal-product-import-information/ct_animal_disease_status. ...

How to catch a pig and its viruses in UgandaHow to catch a pig and its viruses in Uganda
In the latest episode of Contagious Thinking, join CVR PhD student Jack Hirst and postdoc Connor Bamford as they chat with Dr Charles Masembe (follow him on Twitter:@cmasembe10) about his work on some of Africas most important animal viruses.. Charles works currently on a virus called African swine fever virus (ASFV), which causes a deadly disease in domestic pigs that can cause great economic and political turmoil in affected regions. ASFV is a fascinating large DNA virus that is spread by wild pigs and the ticks that feed on them. The virus can move between the wild pigs and farmed domestic pigs. Understanding this movement is a major focus of Charles work.. Charles is a veterinarian and molecular epidemiologist by training and is an associate professor at the College of Natural Sciences at Makerere University in Uganda. He is working in a collaboration with scientists at the CVR to sequence ASFV samples from pigs across Uganda. His work is funded by a recently awarded Wellcome Trust ...

African Swine Fever Risk Means Its Time for Action. The African swine fever (ASF) outbreak in China and in many other countries around the world is wreaking havoc on the international pork industry. Fortunately, ASF is not in the United States at this time, but the possibility of it or other foreign animal disease (FAD) means that American pig farmers must take the necessary steps to protect their farms and the domestic pork industry.. As U.S. pig farmers know, a robust export market is critical to the ongoing success of the nations pork industry. In 2018, U.S. pork and pork variety meats exports totaled 5.37 billion pounds valued at $6.392 billion, according to USDA. If an FDA such as ASF entered the United States, it would likely eliminate this entire valuation to zero for an unknown amount of time, which is why taking steps to prevent it from occurring require immediate action such as those outlined in resources in the link below..

Scrutinizing the greatest threat to pigsScrutinizing the greatest threat to pigs
Long before Georgia 2007 appeared, another strain of ASFV arrived in Portugal in 1957. From Lisbon, the virus crept across the country and reached Spain in 1960; it leaped across that country as pigs were shuffled between recently industrialized farms. With the aid of the soft tick Ornithodoros erraticus, the virus became entrenched in Spains population of wild boars, which mingle often with domestic pigs. For the next two decades, African swine fever flared up in Western Europe, the Caribbean and Brazil. By 1985, pork producers and the Spanish government had had enough and embarked on a successful 10-year campaign of sanitation, detection and eradication. Andrés has been probing ASFVs structure and assembly pathway ever since.. One challenge of working with ASFV is the virus size. ASFV is big - a giant virus, in fact, almost twice the size of influenza virions and thicker than the typical layer of ice in which particles are suspended for cryo-electron microscopy. This complicates sample ...

History of swine fever in southern AfricaHistory of swine fever in southern Africa
Introduction. Classical and African swine fever (CSF, ASF) are the two most feared diseases of swine worldwide. Both are characterised by high mortality and are transboundary diseases that can have devastating effects on livelihoods that depend on pig production (Costard et al. 2009; Moennig 2000). Although they are caused by completely unrelated viruses, the pathogenesis of the two diseases is similar, therefore the clinical and pathological manifestations are strikingly alike (Moennig 2000; Penrith, Thomson & Bastos 2004a). CSF is caused by a single-stranded RNA virus of the genus Pestivirus, family Flaviviridae, while ASF is caused by a large, double-stranded DNA virus that was only allocated to its own genus, Asfivirus, the only member of the family Asfarviridae, in 1998 (Dixon et al. 2005). Both viruses affect only members of the pig family (Suidae) (Moennig 2000; Plowright, Thomson & Neser 1994). Both are highly contagious diseases in pigs and their ancestors, the Eurasian wild boar (Sus ...
