| virulence in african swine fever: its measurement and implications. | a method of measuring and expressing the virulence of african swine fever virus in numerical terms was developed. seventeen viruses (13 hemadsorbing and 4 nonhemadsorbing) were tested and classified into 3 groups: highly infectious and highly virulent, highly infectious and moderately virulent, and slightly infectious and slightly virulent. this classification was based on the number of 50% hemadsorption unit (ha50) or tcid50 required to produce 1 ld50 for swine, the number of ha50 or tcid50 req ... | 1984 | 6711963 |

| experimental transmission of african swine fever virus by the tick ornithodoros (alectorobius) puertoricensis (acari: argasidae). | the soft tick ornithodoros puertoricensis fox has been found on the caribbean island of hispaniola (haiti and the dominican republic) where african swine fever (asf) was endemic from 1978 to 1984. to evaluate the vector potential of o. puertoricensis for african swine fever virus (asfv), second-instar nymphs were experimentally infected by feeding on a viremic pig that was infected with the dominican republic isolate (dr-ii) of asfv. subsequent infection rates and mean virus titers for individua ... | 1991 | 1770521 |
