| antigenic comparison of the polypeptides of foot-and-mouth disease virus serotypes and other picornaviruses. | the cross-reactivity of proteins coded for by the seven serotypes of foot-and-mouth disease virus (fmdv) was assessed by reaction of infected cell lysates with polyclonal and monospecific antisera against the structural and nonstructural proteins of fmdv type a12 strain 119ab. it was shown that the homologous polypeptides from most serotypes are antigenically related. the least cross-reactivity occurred between vp1, vp3, and the protease (3c) of type a12 and south african territories types 1 and ... | 1987 | 2437694 |
| prevalence of human noroviruses in frozen marketed shellfish, red fruits and fresh vegetables. | noroviruses (novs), currently recognised as the most common human food-borne pathogens, are ubiquitous in the environment and can be transmitted to humans through multiple foodstuffs. in this study, we evaluated the prevalence of human nov genogroups i (gi) and ii (gii) in 493 food samples including soft red fruits (n = 200), salad vegetables (n = 210) and bivalve mollusc shellfish (n = 83), using the bovine enterovirus type 1 as process extraction control for the first time. viral extractions w ... | 2014 | 24923255 |
| fatal ulcerative and hemorrhagic typhlocolitis in a pregnant heifer associated with natural bovine enterovirus type-1 infection. | one 2-year-old, 7.5 months pregnant aberdeen angus out of a herd of 100 apparently healthy cows, died within 10 hours of hospitalization. at necropsy, multiple foci of mucosal hemorrhage and ulceration were observed in the spiral colon and cecum. virus isolation from intestinal lesions yielded a cytopathic virus, which was revealed by electron microscopy to be an approximately 27 nm, nonenveloped virus. further characterization by reverse transcription-polymerase chain reaction (rt-pcr), sequenc ... | 2007 | 17197635 |
| comparison of the virucidal efficiency of peracetic acid, potassium monopersulfate and sodium hypochlorite on hepatitis a and enteric cytopathogenic bovine orphan virus. | the virucidal activity of peroxy-products was evaluated and compared with sodium hypochlorite using the en 14675 european suspension test and a surface test developed in our laboratory. the classical approach on infectivity of viruses was complemented with a prospective approach on virus genomes. | 2013 | 23906424 |
| serological survey of bovine enterovirus type 1 in different mammalian species in turkey. | the bovine enterovirus type 1 (bev-1) infection has a wide range of host spectrum including humans. in this study, seroprevalence of bev-1 was investigated in eight mammalian species. blood serum samples were collected from 244 humans, 1520 cattle, 272 horse, 126 dog, 281 sheep, 477 goat, 18 camel (camelus dromedarius) and 82 gazelle (gazella subgutturosa subgutturosa) in different regions of turkey. microneutralization tests showed that gazelle and camel did not have any seropositivities, but s ... | 2008 | 18234029 |
| adhesion of human pathogenic enteric viruses and surrogate viruses to inert and vegetal food surfaces. | enteric viruses, particularly human noroviruses (nov) and hepatitis a virus (hav), are key food-borne pathogens. the attachment of these pathogens to foodstuff and food-contact surfaces is an important mechanism in the human contamination process. studies were done to investigate the nature of the physicochemical forces, such as hydrophobic and electrostatic ones, involved in the interaction virus/matrix but, at this day, only few data are available concerning surface properties of viruses and p ... | 2012 | 22850373 |
| investigations on suitability of different materials for carriers to be used for virucidal testing of chemical disinfectants in the veterinary field. | various materials with rough surfaces were tested to determine their suitability for virus carrier tests designed to evaluate virucidal activity of chemical disinfectants. a non-enveloped rna virus, bovine enterovirus type 1, strain lcr 4 [entero cytopathogenic bovine orphan virus (ecbo)] and an enveloped rna virus, paramyxovirus type 1 [newcastle disease virus (ndv), strain montana] served as test viruses. experiments with ecbo virus were carried out in four sets, and those with ndv in three se ... | 2003 | 14633202 |
| evaluation of virucidal activity of three commercial disinfectants and formic acid using bovine enterovirus type 1 (ecbo virus), mammalian orthoreovirus type 1 and bovine adenovirus type 1. | a modified version of the test method of the comité européen de normalisation (cen) was developed using formic acid and three commercial disinfectants to evaluate virucidal activity against three non-enveloped viruses, bovine enterovirus type 1 (ecbo virus), mammalian orthoreovirus type 1 and bovine adenovirus type 1 (bav 1). determination of the effects of temperature was carried out at 20 and 10 degrees c. all tests with protein load used bovine serum albumin (bsa) and yeast extract. the inves ... | 2003 | 12788019 |
| a study regarding bovine enterovirus type 1 infection in domestic animals and humans: an evaluation from the zoonotic aspect. | bovine enteroviruses (bev) are members of enterovirus genus of the family picornaviridae. bev1 has a broad host spectrum, including humans. the virus usually causes subclinical infection, but fatal/severe cases have also been reported in different animal species. there is quite limited data regarding bev1 in humans. the purpose of this study is to investigate human infection and to identify possible risk factors for viral exposure. for this purpose, blood serum samples (n=1,526) were collected f ... | 2019 | 31564680 |
| [examination of biocides for their effectiveness against animal viruses according to european union standards with emphasis on the selection of a suitable test virus]. | because of the changes to be expected in the methods for testing disinfectants deemed to be used in the veterinary field, candidate viral species were evaluated for their suitability as test virus. considered viral species included different non-enveloped viruses [bovine enterovirus type 1 (ecbo (enteric cytopathogenic bovine orphan) virus), mammalian reovirus type 1, feline calici virus (fcv), and bovine parvovirus (bpv)], as well as enveloped viruses, as equine arteritisvirus (eav), bovine her ... | 2009 | 19226936 |
