Seroprevalance of Anaplasmosis in Cattle in Van, Muş, Siirt and Diyarbakır Provinces

Öz

Anaplasmosis, caused by the genus Anaplasma related to the family Anaplasmataceae the order Rickettsiales, is an infectious disease occurs in mammals in tropical and subtropical climatic regions. Bovine anaplasmosis is usually associated with Anaplasma marginale infection in cattle and its can be transmitted  both mechanically by biting flies or and biologically by ticks. The purpose of this study was to investigate the presence of Anaplasma spp.  in cattle in Van, Mus, Siirt and Diyabakir provinces. cELISA was used to detect specific anti-Anaplasma spp. antibodies in the serum samples. 52 (28.6%) of the 182 asymptomatic cattle were seropositive against Anaplasma. The prevalence of anaplasmosis in female and male cattle was found as 29.3% and 27.3%, respectively and this difference was not found significant. Seropositive rate was statistically differ among the age groups of cattle and the highest seropositive rate was found in 3-5 years. Moreover, the highest seropositive rate of study sites was determined in Siirt as 78.7%. As a result, this is serologic survey for subclinical and chronic  Anaplasma spp. infections performed on cattle in Van, Mus, Siirt and Diyabakir province.

Van, Muş, Siirt ve Diyarbakır İllerinde Sığırlarda Anaplasmosis’in Seroprevalansı

Öz

Rikettsiales dizisi, Anaplasmatacae ailesindeki Anaplasma türlerinin meydana getirdiği anaplasmosis, tropik ve subtropik iklim bölgelerindeki memeli hayvanlarda görülen enfeksiyöz bir hastalıktır. Sığır anaplasmosisi genellikle Anaplasma marginale ile ilişkilendirilir ve bu hastalık hem kan emici sinekler ile mekanik hem de keneler ile biyolojik yolla nakledilir. Bu çalışma Van, Muş, Siirt ve Diyarbakır İllerinde sığırlarda Anaplasma spp. seroprevalansının araştırılması amacıyla yapılmıştır. Serum örnekleri ticari cELISA kiti ile Anaplasma’ya karşı gelişen antikorlar yönünden analiz edilmiştir. Çalışma sonucunda incelenen 182 sığırın 52’sinde (%28,6) Anaplasma spp. antikorları bakımından seropozitiflik saptanmıştır. Dişi sığırlarda seroprevalans %29.3, erkeklerde ise %27.1 olarak belirlenmiş ve bu farklılık istatistiksel açıdan önemsiz bulunmuştur. İstatiksel olarak sığırlarda yaş gruplarına göre farklı seropozitiflik saptanmış olup, en yüksek oran 3-5 (%45.1) yaş arasındaki hayvanlarda bulunmuştur. Ayrıca çalışma merkezleri arasında en yüksek seropozitiflik %78.7 oranı ile Siirt ilinde belirlenmiştir. Sonuç olarak, Van, Muş, Siirt ve Diyarbakır illerinde sığırlarda subklinik ve kronik Anaplasma enfeksiyonlarının varlığı ortaya konulmuştur.
