The first serological evidence for Rift Valley fever infection in the camel, goitered gazelle and Anatolian water buffaloes in Turkey.

Rift valley fever (RVF), a vector-borne zoonotic disease, is caused by a phlebovirus (family Bunyaviridae). The virus was initially characterized approximately 80 years ago in Kenya and disseminated to many countries in the continental Africa, Saudi Arabia, and Yemen. The infection has not been reported in Turkey. In this study, blood serum samples collected from camel (Camelus dromedairus), goitered gazelle (Gazella subgutturosa subgutturosa), and buffaloes (Bubalus bubalis linneaus) from 2000 to 2006 were investigated for RVF using C-ELISA. Camel samples (n = 72) were obtained from private small enterprises in Aydın province in theAegean region. Gazella samples (82) were taken from the biggest captive gazelle herd in Şanlıurfa province in the southeast Anatolia. Buffalo samples were collected mostly from small private family type farms in Afyon (168), Amasya (80), Samsun (69), Ankara (35), Sivas (21), Tokat (19), Konya (10), and Elazığ (8) provinces in the central, north, west, and east Anatolia. All of the gazella samples were negative; whereas, one of the 71 camel samples (1.3%) was positive for RVF-specific antibodies. Buffalos from Sivas, Tokat, Konya, and Elazığ provinces were negative. However, 35 of the 410 samples (8.5%) from rural areas in the following four provinces were positive: Amasya (12/80, 15%), Ankara (5/35, 14.2%), Samsun (8/69, 11.5%), and Afyon (10/168, 5.9%). To our knowledge, this is the first report of presence of RVF infection in Turkey.
