FMD outbreaks 1998 ² 1999 in the Middle East
(Israel, Jordan, Palestinian Authority)

Hagai Yadin, Boris Gelman, Yehoda Stram and Dalia Chai Kimron Veterinary Institute, Beit Dagan, 50250, Israel.

 

1998 was a FMD free year, 5 suspected samples from Israel were investigated with negative results. No samples were submitted from the Palestinian Authority.
1999 began with the first FMD outbreak on January 13 in a beef cattle herd close to the Lebanese border. During the following months 20 more outbreaks were recognized and diagnosed. 10 herds of beef cattle and 11 of small ruminants were affected. The monthly distribution of the outbreaks was: 1 in January, 5 in February, 3 in March, 2 in April, 2 in May, 4 in June, 2 in July and 2 in August.
On February 3rd a specimen from a goat with clinical signs from Taybe in South Lebanon was found positive demonstrating the existence of FMD also in Lebanon. In addition, a communication of the Lebanese Ministry of Agriculture in February 99 acknowledged that an FMD outbreak in the Baalbek-Hermel region had killed hundreds of sheep.
The Palestinian Veterinary Services submitted 8 specimens to KVI for FMD diagnosis between February and April 99. Three of the samples from 3 different locations were O1 positive.
The Jordanian Veterinary Services submitted 19 FMD suspected specimens to KVI from dairy and beef cattle, sheep and goats from all over the Kingdom. 17 of the samples were FMD positive either by Elisa or virus isolation or both.
Investigation of the r value of selected 1999 isolates from Lebanon, Israel, Jordan and P.A revealed that all isolates have r value of 0.9 - 1.0 related to O1 Dalton.
Genetic comparison of selected 1999 isolates shows nucleotide differences of 1- 4 percent. This fact indicate that 1999 FMD outbreaks in the Near East countries originated from a common source. The common origin is supposed to be the large FMD outbreak described in 98 ² 99 in Iraq.
