| Popis: | Foot and mouth disease (FMD) epidemics recur in Israel almost every year. Wild even-toed ungulates are seldom affected during these epidemics. The sero-prevalence of FMD in wild ungulates during 2000 and 2005-13 was estimated using anti non-structural proteins (NSP) ELISA. Overall, 209 samples were tested, comprising sera of 120 wild boar (Sus scrofa lybicus), 64 mountain gazelles (Gazella gazella gazella), six water buffaloes (Bubalus bubalis), and 19 Persian fallow deer (Dama dama mesopotamica). None of the tested animals presented clinical signs of FMD during blood collection. Sixteen samples (7.7% (95% confidence interval (CI95%) = 4.4 - 12.1%)) were found to be sero-positive. Fifteen out of 120 samples (12.5%) from wild boar were sero-positive, compared with only one out of 89 samples (1.1%) from all other species combined (Fisher's Exact test: p=0.003). Most of the positive samples obtained from wild boar (13/15 (86.7%)) were collected during 2007 and analysis was restricted to that year and species only. The sero-prevalence of FMD in this species during 2007 was estimated at 54.2% (CI95%=32.8 - 74.5%; n=24). A significant infection cluster, comprising nine sero-positive samples collected in three different locations, was identified in the north-eastern part of Israel. These findings indicate that wild boar were affected during the 2007 FMD epidemic, even though wild boar presenting FMD typical clinical signs were not observed during that year. The actual role of wild boar in the spread of FMD virus in this epidemic, however, could not be determined. The negligible sero-prevalence of FMD found for all other surveillance years indicates that ongoing circulation of FMD among wildlife in Israel is unlikely. It is concluded that while the role of wildlife species in the dynamics of FMD in Israel is usually limited, there might be occasions in which wildlife play a part in the spread of the virus. |
