Abstract
African Swine Fever Virus Strain Georgia 2007/1 in<i>Ornithodoros erraticus</i>Ticks
Highlights
Most field strains of African swine fever virus (ASFV) can persistently infect Ornithodoros ticks, including the species O. erraticus in southern Europe [2], and ASFV has been isolated from ticks collected >5 years after the last confirmed case in an outbreak [3]
It is not known if the Georgia 2007/1 ASFV strain responsible for continuing outbreaks in the Caucasus region can replicate in ticks
Results showed that the Georgia 2007/1 strain can replicate in the O. erraticus tick
Summary
To the Editor: African swine fever virus (ASFV) causes a notifiable disease in domestic pigs for which no treatment or vaccine is available, resulting in a mortality rate of 5 years after the last confirmed case in an outbreak [3]. Heparinized pig blood containing antibacterial drugs and fungicide (10 μL of streptomycin [10,000 IU/mL], 10 μL of amphotericin B [250 μg/mL], and 5 μL of neomycin [10 mg/mL 0.9% NaCl]/mL of blood) was mixed with the Georgia 2007/1 isolate [4] or the OUR T88/1 isolate [5] as a positive control to obtain virus titers of 4 log or 6 log10 50% hemadsorbing doses (HAD50)/mL blood. General linear model of the effects of different parameters on the titer of ASFV in experimentally infected Ornithodoros erraticus ticks*
