Abstract

Amaç: Bu çalışmanın
amacı Düzce ilindeki koyunlarda, Coxiella
burnetii ve Chlamydia abortus
etkenine karşı spesifik antikorları araştırmaktır. Q humması ve koyunların
enzootik abortusu hastalıklarının ayrı ayrı nedeni olan söz konusu 2 patojen,
küçük ruminantlarda yavru atmalar ile ilişkilidir. Mikrobiyal etkenlerin neden
olduğu yavru atmalara bağlı ekonomik kayıplar dünyanın birçok ülkesinde kayda
değer seviyededir.

Gereç ve
Yöntemler:
Çalışma kapsamında serolojik testler için koyun kan örnekleri Düzce ilinden
toplandı. Ticari ELISA kitleri, C.
burnetii ve C. abortus
etkenlerine karşı spesifik antikorların tespiti için kullanıldı. Düzce ilinin 5
ilçesindeki 12 köy veya mahallede yer alan 14 sürüden alınmış 72 numune
çalışmada kullanıldı. Numuneler, 2-5 yaş aralığında yavru atma geçmişi olmayan
dişi hayvanlardan alındı.

Bulgular: Sırasıyla
koyunların enzootik abortusu ve Q humması hastalıkları için total seroprevalans
%20,83 ve %26,38 olarak bulundu. Fakat seropozitif sürü oranı, total
seroprevalansdan daha yüksek oranda sırasıyla koyunların enzootik abortusu ve Q
humması hastalıkları için %42,8 ve %50 olarak bulundu. 14 sürü içinde 7 sürüde
her iki hastalık için seropozitif hayvanlar tespit edildi.

Sonuç: Çalışma
sonuçları Düzce ilindeki araştırılan koyun sürülerinin C. burnetii ve C. abortus
etkenlerine maruz kaldığını doğrulamaktadır. Elde edilen verilere göre, Düzce
ilinde koyun yavru atma vakalarında çalışmada araştırılan iki abort etkenin
muhtemel bağlantısının değerlendirilmesi faydalı olacaktır.

Investigation of Coxiella burnetii and Chlamydia abortus Antibodies in Sheep in Düzce Region

Abstract

Aim: The aim
of this study is to investigate the Coxiella
burnetii and Chlamydia abortus
antibodies in sheep in Düzce province. These two pathogens are causative agents
of Query fever and Enzootic abortion of ewes, respectively which are related to
abortion in small ruminants. Economic loss due to the abortions which are
caused by microbiological agents is considerably high in many countries.

Material and Methods: Blood samples of sheep were collected from Düzce province of Turkey for
serological tests. Commercial enzyme-linked immunosorbent assay (ELISA) was
used for the detection of specific antibodies to C. burnetii and C. abortus.
A total of 72 samples obtained from 14 herds located in 12 villages/districts
of 5 towns in Düzce province were utilized in this study. Samples were
collected from 2-5-year-old female animals without an abortion history.

Results: Total seroprevalence
of Enzootic abortion of ewes and Query fever was found to be 20.83% and 26.38%,
respectively. However, the proportion of seropositive herds was found to be
42.8% for Enzootic abortion of ewes and 50% for Q fever, which is higher than
total seroprevalence. 6 flocks out of 14 were found to be seropositive for both
of the diseases simultaneously.

Conclusion: This study confirms the exposure of sheep herds in Düzce province to C. burnetii and C. abortus and provides original seroprevalence data about Düzce.
The data gathered are beneficial to evaluate the possible connection of two
investigated abortogenic pathogens in sheep abortion cases in Düzce province.
