  • A major-capsid-protein-based multiplex PCR assay for rapid identification of selected virulent bacteriophage types
    Item type: Journal Article

    Bacteriophages represent a promising alternative for controlling pathogenic bacteria. They are ubiquitous in the environment, and their isolation is usually simple and fast. However, not every phage is suitable for biocontrol applications. It must be virulent (i.e., strictly lytic), non-transducing, and safe. We have developed a method for identifying selected types of virulent phages at an early stage of the isolation process to simplify the search for suitable candidates. Using the major capsid protein (MCP) as a phylogenetic marker, we designed degenerate primers for the identification of Felix O1-, GJ1-, N4-, SP6-, T4-, T7-, and Vi1-like phages in multiplex PCR setups with single phage plaques as templates. Performance of the MCP PCR assay was evaluated with a set of 26 well-characterized phages. Neither false-positive nor false-negative results were obtained. In addition, 154 phages from enrichment cultures from various environmental samples were subjected to MCP PCR analysis. Eight of them, specific for Salmonella enterica, Escherichia coli, or Erwinia amylovora, belonged to one of the selected phage types. Their PCR-based identification was successfully confirmed by pulsed-field gel electrophoresis of the phage genomes, electron microscopy, and sequencing of the amplified mcp gene fragment. The MCP PCR assay was shown to be a simple method for preliminary assignment of new phages to a certain group and thus to identify candidates for biocontrol immediately after their isolation. Given that sufficient sequence data are available, this method can be extended to any phage group of interest.
  • Mobilisation into cotton and spread of a recombinant cotton leaf curl disease satellite
    Item type: Journal Article
    Amin, Imran; Mansoor, Shahid; Amrao, Luqman; et al. (2006)
    Archives of Virology
    Analysis of a DNA β satellite associated with a recently identified cotton leaf curl disease (CLCuD) strain indicated it to be recombinant, with most of the molecule originating from CLCuD DNA β but with some sequence from a satellite isolated from tomato. Analysis of both archival (pre 2001) and recent cotton samples, shows the recombinant satellite is confined to a small area but was not present in cotton prior to 2001. This indicates that the recombinant DNA β was recently mobilized into cotton, likely from tomato, and that recombination plays a role in the evolution of these satellites.

  • Diversity of begomovirus DNA β satellites of non-malvaceous plants in east and south east Asia
    Item type: Journal Article
    Bull, Simon; Tsai, Wenshi; Briddon, Rob W.; et al. (2004)
    Archives of Virology
    Two previous analyses of the diversity of begomovirus-associated DNA β satellites focused predominantly on molecules originating from the Indian sub-continent and southern China. They showed the satellites to group according to the hosts from which they were isolated, either malvaceous or non-malvaceous plants, and then to form sub-groups based upon geographic origin and host. In this study we analysed the diversity of DNA β satellites in east and south east Asia. Here the satellites group by geographic location and are considerably more diverse than previously indicated. This probably reflects the limited movement of begomovirus/DNA β complexes in this region and their subsequent diversification from a common ancestor to a variety of hosts.
  • Course and transmission characteristics of oral low-dose infection of domestic pigs and European wild boar with a Caucasian African swine fever virus isolate
    Item type: Journal Article
    Pietschmann, Jana; Guinat, Claire; Beer, Martin; et al. (2015)
    Archives of Virology
    In 2007, African swine fever virus (ASFV) was introduced into the Transcaucasian countries and Russia. Since then, it has spread alarmingly and reached the European Union. ASFV strains are highly virulent and lead to almost 100 % mortality under experimental conditions. However, the possibility of dose-dependent disease courses has been discussed. For this reason, a study was undertaken to assess the risk of chronic disease and the establishment of carriers upon low-dose oronasal infection of domestic pigs and European wild boar. It was demonstrated that very low doses of ASFV are sufficient to infect especially weak or runted animals by the oronasal route. Some of these animals did not show clinical signs indicative of ASF, and they developed almost no fever. However, no changes were observed in individual animal regarding the onset, course and outcome of infection as assessed by diagnostic tests. After amplification of ASFV by these animals, pen- and stablemates became infected and developed acute lethal disease with similar characteristics in all animals. Thus, we found no indication of prolonged or chronic individual courses upon low-dose infection in either species. The scattered onset of clinical signs and pathogen detection within and among groups confirms moderate contagiosity that is strongly linked with blood contact. In conclusion, the prolonged course at the “herd level” together with the exceptionally low dose that proved to be sufficient to infect a runted wild boar could be important for disease dynamics in wild-boar populations and in backyard settings. © 2015, Springer-Verlag Wien.
  • Cotton leaf curl disease is associated with multiple monopartite begomoviruses supported by single DNA β
    Item type: Journal Article
    Mansoor, Shahid; Briddon, Rob W.; Bull, Simon; et al. (2003)
    Archives of Virology
    For bipartite begomoviruses (family Geminiviridae) trans-replication of the DNA B component by the DNA A-encoded replication-associated protein (Rep) is achieved by virtue of a shared sequence, the “common region”, which contains repeated motifs (iterons) which are sequence-specific Rep binding sites and form part of the origin of replication. Recently cotton leaf curl disease (CLCuD), a major constraint to cotton production on the Indian subcontinent, has been shown to be caused by a monopartite begomovirus (Cotton leaf curl Multan virus [CLCuMV]) and a novel single-stranded DNA satellite molecule termed CLCuD DNA β. The satellite molecule is trans-replicated by CLCuMV but does not possess the iteron sequences of this virus. We have investigated the ability of CLCuD DNA β to interact with three further clones of monopartite begomoviruses, isolated from cotton, that have distinct Rep binding specificities. All three cloned viruses were capable of trans-replicating the satellite molecule and inducing CLCuD symptoms in cotton, indicating that the interaction between begomovirus and DNA β is relaxed in comparison to the interaction between DNA A and DNA B components. Field surveys across all the cotton growing regions of Pakistan indicate that dual and multiple infections are the norm for CLCuD with no evidence of synergism. Despite the diversity of begomoviruses associated with CLCuD, only a single class of DNA β has been detected, suggesting that this satellite has the capacity to be recruited by unrelated begomoviruses.
