“…Swine vesicular disease was first observed in Italy in 1966 (Nardelli et al 1968) and physicochemical examination indicated that the causative agent was an enterovirus. Subsequent outbreaks occurred in Hong Kong in 197I (Mowat,Darbyshire & Huntley,I972) and in Europe and Japan in x972-5 (Brooksby, I975).…”

SUMMARYThe relatedness of swine vesicular disease virus (SVDV) and Coxsackie B5 virus has been studied by virus neutralization and immunodiffusion tests and by hybridization of the virus RNAs. Clearly defined differences between the two viruses were found by the three methods. Isolates of SVDV from several countries were very closely related but could be differentiated. Recent isolates of Coxsackie B5 virus also appeared to be similar but clear differences could be detected between these and the prototype (Faulkner) strain of the virus. The SVDV isolates were more closely related to the Faulkner strain than to the recent isolates of Coxsackie B5 virus. Perhaps of more importance, the Faulkner strain was more closely related to SVDV than it was to the recent Coxsackie B5 isolates. The significance of these observations in relation to the recent emergence of swine vesicular disease is discussed.

“…Teschovirus encephalomyelitis (previously Teschen/Talfan diseases, and later Enterovirus encephalomyelitis) is an acute condition of pigs characterised by central nervous system disorders (Knowles, 2008). On the other hand, serotypes other than PTV-1 were described as causative agents of enteric disease (Izawa et al, 1962), pneumonia (Meyer et al, 1966), aphtaelike dermal lesions of swine (Nardelli et al, 1968;Knowles, 1988) and reproductive failure (Dunne et al, 1965).…”

ABSTRACT:The porcine enteroviruses (family Picornaviridae) were described as causative agents of neurological disorders known as Teschen/Talfan disease, reproductive failure, dermal lesions, enteric disease and pneumonia of swine. Recently, porcine enteroviruses were reclassified on the basis of genome sequencing data. A new Picornavirus genus named Teschovirus (formerly PEV CPE group I.) was established. The aim of the study was retyping and reclassification of the 27 strains of porcine enteroviruses deposited in the Collection of Animal Pathogenic Microorganisms (CAPM). Viral strains were isolated over the period 1960-1980 predominantly from pigs with encephalomyelitis. Twenty-four of 27 isolates were classified as porcine enterovirus serotype 1 (PEV-1) based on physicochemicals properties of their virions and growth characteristics. The viral strains were reclassified using RT-PCR protocol that allowed detection of the genus Teschovirus and the Porcine teschovirus serotype 1 (PTV-1). Two PCR amplifications with cDNA were performed for detection of the genus Teschovirus and PTV-1. Amplification of fragment characteristic for the genus Teschovirus was succesful for all tested viral strains. The fragment characteristic for PTV-1 was detected with the exception of three strains (Kr69TK, 95 and 172). Used RT-PCR method was subsequently applied to the detection of Porcine teschovirus in pig fecal samples. Ten of 22 faecal samples were found to be Porcine teschovirus positive, however none of 22 samples generated amplicon specific for the PTV-1.

“…The mixtures were incubated at room temperature for 30 min. The J1 strain was mixed with an equal volume of alkylbenzyldimethylammonium chloride (ABDAC) [3] or [mono-bis (trimethylammonium-methylene chloride)]-alkyl (C [9][10][11][12][13][14][15] ) toluene (MBTAMCAT) [4] diluted with distilled water to give the same final concentrations and NaOH content as DDAC. The experiment conditions were the same as for DDAC.…”

ABSTRACT. The effects of quaternary ammonium compounds (QACs) with sodium hydroxide on swine vesicular disease virus (SVDV), an enterovirus were studied. Didecyldimethylammonium chloride (DDAC) with 0.1% NaOH showed a stronger effect against SVDV than other QACs with 0.1% NaOH. The effect of DDAC with 0.1% NaOH was strong at 40ºC. DDAC was effective against SVDV at pH values around 11.0, but not in the distilled water control. The effect of DDAC with 0.1% NaOH was already observed at 1 min after mixing of the DDAC with SVDV. Observation under an electron microscopy revealed that the probable mechanism of inactivation of DDAC with 0.1% NaOH is as follows: The virus particles were partially destroyed by 0.1% NaOH. DDAC gathered these affected particles and formed a micelle, then SVDV lost its infectivity. From these results, QACs with 0.1% NaOH are considered to be very effective against SVDV representing enteroviruses. -KEY WORDS: disinfection, electron microscopy, 0.1% NaOH, quaternary ammonium compound, swine vesicular disease virus.
