    Afyon, Konya ve Eskişehir illerinde keçilerde Pestivirus ve Parainfluenzavirus Tip 3 enfeksiyonlarının serolojik olarak araştırılması
    (2009) Gür, Sibel; Erol, Nural; Yapıcı, Orhan
    Bu çalışmada sağlıklı ve respiratorik-reprodüktif bozukluklar görülen keçi sürülerinde Pestivirus ve Parainfluenzavirus 3 (PI-3) enfeksiyonları serolojik olarak araştırıldı. Afyonkarahisar, Konya ve Eskişehir illerindeki 7 sürüden toplam 1346 kan örneği elde edildi. Mikronötralizasyon test sonucuna göre, sürü bazında pestivirus spesifik antikorların %35.2 ile %78.8 arasında değiştiği belirlenirken PI-3 için %17.5 ile %62 aralığında olduğu tespit edildi. Toplamda, 933 (%69.3) ve 584 (%43.3) keçinin sırasıyla pestivirus ve PI-3 için pozitif olduğu saptandı. PI-3 için pozitif olduğu belirlenen örneklerin %83.5’inin pestivirus için de pozitif olduğu belirlenirken pestivirus pozitiflerin sadece %52.3’ünün PI-3 için de pozitif olduğu saptandı.

    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 AydA +/- n province in theAegean region. Gazella samples (82) were taken from the biggest captive gazelle herd in AanlA +/- urfa 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 ElazA +/- g (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 ElazA +/- g 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.

    The role of goats as reservoir hosts for bovine herpes virus 1 under field conditions
    (SPRINGER, 2019) Gür, Sibel; Erol, Nural; Yapıcı, Orhan; Kale, Mehmet; Tan, Mehmet Tolga; Turan, Turhan; Çakmak, Mehmet Atilla; Tosun, Cemil; Yılmaz, Simay; Acar, Abuzer; Özenli, Işınsu; Gür, Coşkun
    Bovine herpesvirus 1 (BoHV1) is the cause of economically significant viral infections in cattle. Respiratory symptoms associated with the infection are known as Infectious Bovine Rhinotracheitis (IBR). Sheep and goats are less sensitive to the infection although their role in inter-species viral transmission under field conditions is subject to controversy. The objective of this study was to investigate seroprevalence of BoHV1 infections in cattle, sheep, and goats raised together for at least a year. Blood serum samples were taken from 226 cattle, 1.053 sheep, and 277 goats from 17 small- to medium-scale farms. BoHV1-specific antibody presence and titers were determined using virus neutralization test. In total, 73 of the 226 cattle (32.3%) were seropositive. The infection was detected in 13 of the 17 farms. Infection rates ranged from 5.8 to 88.8%. Only one of the 1053 sheep (0.09%) was seropositive. However, 58 of the 277 (20.9%) goats were seropositive. Goat samples taken from 8 of the 17 farms were seropositive with infection rates ranging from 17 to 38.9%. Statistical analysis showed a significant correlation in infection rates between cattle and goats but not sheep. These results suggest that goats may be more sensitive to the BHV1 infection than sheep and the role of goats as possible reservoirs for BoHV1 in the control and eradication of BHV1 in cattle should be considered in future studies.
