Modulation of monocytic cell activity and virus susceptibility during differentiation into macrophages. (1/107)

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)

African swine fever virus: a B cell-mitogenic virus in vivo and in vitro. (2/107)

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. (3/107)

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 virus dUTPase is a highly specific enzyme required for efficient replication in swine macrophages. (4/107)

The African swine fever virus (ASFV) gene E165R, which is homologous to dUTPases, has been characterized. A multiple alignment of dUTPases showed the conservation in ASFV dUTPase of the motifs that define this protein family. A biochemical analysis of the purified recombinant enzyme showed that the virus dUTPase is a trimeric, highly specific enzyme that requires a divalent cation for activity. The enzyme is most probably complexed with Mg(2+), the preferred cation, and has an apparent K(m) for dUTP of 1 microM. Northern and Western blotting, as well as immunofluorescence analyses, indicated that the enzyme is expressed at early and late times of infection and is localized in the cytoplasm of the infected cells. On the other hand, an ASFV dUTPase-deletion mutant (vDeltaE165R) has been obtained. Growth kinetics showed that vDeltaE165R replicates as efficiently as parental virus in Vero cells but only to 10% or less of parental virus in swine macrophages. Our results suggest that the dUTPase activity is dispensable for virus replication in dividing cells but is required for productive infection in nondividing swine macrophages, the natural host cell for the virus. The viral dUTPase may play a role in lowering the dUTP concentration in natural infections to minimize misincorporation of deoxyuridine into the viral DNA and ensure the fidelity of genome replication.  (+info)

Intermediate stages in monocyte-macrophage differentiation modulate phenotype and susceptibility to virus infection. (5/107)

The kinetics of monocyte-macrophage differentiation was analysed using two Swine Workshop Cluster (SWC) CD molecules: SWC1 and SWC9. Myeloid cells were selected by labelling for the common myeloid antigen, SWC3. Confirmation of macrophage identification used acid phosphatase and phagocytosis activities. During differentiation, SWC1 was gradually lost. SWC9 was absent on monocytes but up-regulated early. Consequently, monocytes were SWC1+ SWC9- and macrophages were SWC1- SWC9+. An additional, intermediate, cell population was identified as SWC1+ SWC9+. Size and granularity characteristics mirrored the monocyte, macrophage and intermediate-cell phenotypes. Overall, SWC9 up-regulation was central in macrophage differentiation and dependent on plasma factors. The concomitant loss of SWC1 was independent of these factors, but always associated with mature macrophages. Upon up-regulation of SWC9, the SWC1+ SWC9+ intermediate monocytic cells became susceptible to African swine fever virus infection. These results demonstrate the heterogeneity of monocytic cell differentiation and the importance of these characteristics for interaction with monocytotropic viruses.  (+info)

An African swine fever virus ORF with similarity to C-type lectins is non-essential for growth in swine macrophages in vitro and for virus virulence in domestic swine. (6/107)

An African swine fever virus (ASFV) ORF, 8CR, with similarity to the C-type lectin family of adhesion proteins has been described in the pathogenic isolate Malawi Lil-20/1. The similarity of 8CR to cellular and poxvirus genes associated with cell adhesion, cell recognition and virus infectivity suggested that 8CR may be of significance to ASFV-host cell interactions. Sequence analysis of the 8CR ORF from additional pathogenic ASFV isolates demonstrated conservation among isolates from both pig and tick sources. Northern blot analysis demonstrated 8CR mRNA transcription late in the virus replication cycle. A Malawi Lil-20/1 8CR deletion mutant (delta8CR) was constructed to analyse 8CR function further. The growth characteristics in vitro of delta8CR in porcine macrophage cell cultures were identical to those observed for parental virus. In domestic swine, delta8CR exhibited an unaltered parental Malawi Lil-20/1 disease and virulence phenotype. Thus, although well conserved among pathogenic ASFV field isolates, 8CR is non-essential for growth in porcine macrophages in vitro and for virus virulence in domestic swine.  (+info)

An African swine fever virus ERV1-ALR homologue, 9GL, affects virion maturation and viral growth in macrophages and viral virulence in swine. (7/107)

The African swine fever virus (ASFV) genome contains a gene, 9GL, with similarity to yeast ERV1 and ALR genes. ERV1 has been shown to function in oxidative phosphorylation and in cell growth, while ALR has hepatotrophic activity. 9GL encodes a protein of 119 amino acids and was highly conserved at both nucleotide and amino acid levels among all ASFV field isolates examined. Monospecific rabbit polyclonal antibody produced to a glutathione S-transferase-9GL fusion protein specifically immunoprecipitated a 14-kDa protein from macrophage cell cultures infected with the ASFV isolate Malawi Lil-20/1 (MAL). Time course analysis and viral DNA synthesis inhibitor experiments indicated that p14 was a late viral protein. A 9GL gene deletion mutant of MAL (Delta9GL), exhibited a growth defect in macrophages of approximately 2 log(10) units and had a small-plaque phenotype compared to either a revertant (9GL-R) or the parental virus. 9GL affected normal virion maturation; virions containing acentric nucleoid structures comprised 90 to 99% of all virions observed in Delta9GL-infected macrophages. The Delta9GL virus was markedly attenuated in swine. In contrast to 9GL-R infection, where mortality was 100%, all Delta9GL-infected animals survived infection. With the exception of a transient fever response in some animals, Delta9GL-infected animals remained clinically normal and exhibited significant 100- to 10,000-fold reductions in viremia titers. All pigs previously infected with Delta9GL survived infection when subsequently challenged with a lethal dose of virulent parental MAL. Thus, ASFV 9GL gene deletion mutants may prove useful as live-attenuated ASF vaccines.  (+info)

Effects of chlorine, iodine, and quaternary ammonium compound disinfectants on several exotic disease viruses. (8/107)

The effects of three representative disinfectants, chlorine (sodium hypochlorite), iodine (potassium tetraglicine triiodide), and quaternary ammonium compound (didecyldimethylammonium chloride), on several exotic disease viruses were examined. The viruses used were four enveloped viruses (vesicular stomatitis virus, African swine fever virus, equine viral arteritis virus, and porcine reproductive and respiratory syndrome virus) and two non-enveloped viruses (swine vesicular disease virus (SVDV) and African horse sickness virus (AHSV)). Chlorine was effective against all viruses except SVDV at concentrations of 0.03% to 0.0075%, and a dose response was observed. Iodine was very effective against all viruses at concentrations of 0.015% to 0.0075%, but a dose response was not observed. Quaternary ammonium compound was very effective in low concentration of 0.003% against four enveloped viruses and AHSV, but it was only effective against SVDV with 0.05% NaOH. Electron microscopic observation revealed the probable mechanism of each disinfectant. Chlorine caused complete degeneration of the viral particles and also destroyed the nucleic acid of the viruses. Iodine destroyed mainly the inner components including nucleic acid of the viruses. Quaternary ammonium compound induced detachment of the envelope of the enveloped viruses and formation of micelle in non-enveloped viruses. According to these results, chlorine and iodine disinfectants were quite effective against most of the viruses used at adequately high concentration. The effective concentration of quaternary ammonium compound was the lowest among the disinfectants examined.  (+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 ...
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 : ...
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.. South Korea ...

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 ...

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 ...

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
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 ...
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.
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

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.

AFRICA - The Food and Agriculture Organization of the United Nations (FAO) has joined with two African organisations to develop a regional strategy for the control of African swine fever (ASF) for the continent.
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

Complete feed accounts for 42% of hog feed consumption," eFeedLinks Eric Brooks noted. Another eFeedLink analyst, Shi Tao, stated that, "In June 2019, nine (out of 22) provinces slashed the output of complete hog feed by more than 50% compared with June 2018. The output of another nine provinces decreased by more than 20%. Total complete hog feed output fell by 32.4% year-on-year.".
