“…As previously reported by Beck and Strohmaier [22], European isolates are the exception, since they are considerably more homogeneous and clearly associated to vaccine strains. A similar evolutionary trend has been reported for type A and O viruses [9,206]. The molecular basis of the serotype diversification is not fully understood and may have involved both positive selection and random sampling events (reviewed in [79]).…”

“…These procedures are highly sensitive and reduce the time needed for viral detection. In addition, RT-PCR amplification, in combination with direct nucleotide sequencing, has become an important tool for the rapid characterisation of field isolates and the tracing of new outbreaks [9,128]. Sequencing analyses have been mainly focused on the gene encoding capsid protein VP1 (see Sect.…”

Foot-and-mouth disease virus: a long known virus, but a current threat

-Foot-and-mouth disease virus (FMDV) was the first animal virus identified. Since then, FMDV has become a model system in animal virology and a considerable amount of information on its structure, biology and vaccinology has been obtained. However, the disease that this virus produces (FMD) still constitutes one of the main animal health concerns. In this review, we have attempted to summarise the state of the knowledge in different basic and applied areas of FMDV research, with emphasis on those aspects relevant to the control of the disease. FMDV / structure / immunity / vaccine / variability / diagnosisRésumé -Le virus de la fièvre aphteuse : un virus connu de longue date, qui demeure une menace. Le virus de la fièvre aphteuse a été le premier virus animal identifié. Depuis lors, il est devenu un système modèle en virologie animale, et une quantité importante d'informations sur sa structure, sa biologie et sa vaccinologie a été obtenue. Cependant la maladie provoquée par ce virus constitue encore une inquiétude majeure en santé animale. Dans cette revue, nous avons tenté de résumer l'état des connaissances dans différents domaines de recherche, à la fois fondamentaux et appliqués, sur le virus de la fièvre aphteuse, en mettant l'accent sur les aspects relatifs au contrôle de la maladie. virus de la fièvre aphteuse / immunité / vaccin / variabilité / diagnostic

“…Sequence analysis showed that the type A component of the SAU/42/91 isolate was most closely related to a group of viruses which caused outbreaks in Turkey during 1991-2 [23] and Saudi Arabia in 1991 (A. R. Samuel, unpublished data). The Saudi Arabian viruses were not closely related to the previous type A outbreak strains from 1986-7 [24] which were more closely related to viruses from the Indian sub-continent [25]. Recent samples received from Saudi Arabia in 1993 have been typed as mixtures of type O and A and similarly samples from two outbreaks in Turkey in 1991 have also been found to be mixtures of serotypes 0 and A.…”

Analysis of mixed foot–and–mouth disease virus infections in Saudi Arabia: prolonged circulation of an exotic serotype

et al. 1994

View full text Add to dashboard Cite

Plaque purification of foot-and-mouth disease (FMD) type O viruses isolated from cattle in Saudi Arabia showed the presence of mixed serotype infections. Sixteen out of 31 samples collected between 1985 and 1991 also contained Asia 1 virus, a serotype which had previously only been isolated from a single outbreak in that country in 1980. Nucleotide sequences of the Asia 1 component of all these samples revealed little variation and showed that they were closely related to both a Russian lapinized vaccine virus strain (Asia 1/Tadzhikistan/64), and to a field isolate from Turkey (Asia 1/TUR/15/73). Although mixed FMD infections have been observed previously this is a first report of a serotype, considered to be exotic to a country, co-existing undetected for an extended period of time.

“…Extensive studies on the genetic and antigenic variation of FMDV serotypes O and Asia-1 have been carried out worldwide. Unlike serotype O and Asia-1 virus, serotype A isolates have shown extensive antigenic variation (Arrowsmith 1975;Belwal et al 1986;Belwal et al 1987;Armstrong et al 1994;Azad et al 1995;Araujo et al 2002). Several workers (Tosh et al 2004;Mittal et al 2005;Jangra et al 2005;Mohapatra et al 2008) have studied genetic and antigenic variation in Indian FMDV isolates.…”

Genetic analysis of foot-and-mouth disease virus serotype A of Indian origin and detection of positive selection and recombination in leader protease- and capsid-coding regions

et al. 2009

The leader protease (L pro) and capsid-coding sequences (P1) constitute approximately 3 kb of the foot-and-mouth disease virus (FMDV). We studied the phylogenetic relationship of 46 FMDV serotype A isolates of Indian origin collected during the period 1968-2005 and also eight vaccine strains using the neighbour-joining tree and Bayesian tree methods. The viruses were categorized under three major groups -Asian, Euro-South American and European. The Indian isolates formed a distinct genetic group among the Asian isolates. The Indian isolates were further classi?ed into different genetic subgroups (<5% divergence).Post-1995 isolates were divided into two subgroups while a few isolates which originated in the year 2005 from Andhra Pradesh formed a separate group. These isolates were closely related to the isolates of the 1970s. The FMDV isolates seem to undergo reverse mutation or convergent evolution wherein sequences identical to the ancestors are present in the isolates in circulation. The eight vaccine strains included in the study were not related to each other and belonged to different genetic groups. Recombination was detected in the L pro region in one isolate (A IND 20/82) and in the VP1 coding 1D region in another isolate (A RAJ 21/96). Positive selection was identi?ed at aa positions 23 in the L pro (P < 0.05; 0.046*) and at aa 171 in the capsid protein VP1 (P < 0.01; 0.003**).
