Abstract

This study was aimed to determine the performance of
cytopathology for the diagnosis of B.
canis on the basis of a comparison with culture, PCR and ELISA results. For
this purpose, swabs for cytological, molecular and bacteriological examinations
blood serum samples for serological tests were taken from 147 dogs which are
suspected to have genital infection.. While the cytological samples were
stained with May-Grünwald Giemsa solution, the swab samples were tested by
bacteriologically and PCR and the serum samples were assayed by ELISA.
According to the results, while ELISA yielded a seropositivity rate of 11.5%,
PCR demonstrated a positivity rate of 1.8%. No B. canis could be isolated from the samples were taken for
bacteriological examinations. At cytological examination, it was observed that
the samples contained coccobacilli presented with abundant neutrophil
leukocytes and macrophages. Some of these immune cells and epithelial cells
were observed to contain round/oval shaped bacteria in their cytoplasm. The
results of this study suggest that cytopathology can be used for auxiliary test
for the diagnosis of brucellosis.

Brucella canis’in Tanısında Eksfolyatif Sitopatoloji Verilerinin Polimeraz Zincir Reaksiyonu (PZR), Kültür ve ELISA Yöntemleri ile Karşılaştırması

Abstract

Bu çalışmada, B. canis’in
tanısında sitopatolojik yöntemin kullanılabilirliğinin PCR, kültür ve ELISA
yöntemleri ile belirlenmesi amaçlandı. Bu amaçla toplam 147 genital sistem
enfeksiyonu şüphesi olan köpekten alınan sitolojik, swap ve kan serumu
örnekleri incelendi. Sitolojik örneklere May Grünwald Giemsa boyaması
yapılırken, mikrobiyolojik incelemeler amacıyla elde edilen swaplar
bakteriyolojik kültür ve PCR ile test edildiler. Serum örnekleri ELISA ile test
edildi. Yapılan çalışmalar sonucu ELISA yöntemiyle yapılan incelemelerde %11.5
oranında seropozitiflik, PCR yönteminde ise %1.8 oranında pozitiflik tespit
edildi. Bakteriyolojik muayene için alınan örneklerde B. canis izole edilemedi. Sitolojik incelemelerde kokobasil ile
beraber çok sayıda nötrofil lökosit ve makrofajla karşılaşıldı. Yer yer bu
hücrelerin ve epitel hücrelerin sitoplazmasında yuvarlak-oval şekilli
etkenlerle karşılaşıldı. Yapılan bu çalışmanın sonuçları sitopatolojinin
brusellanın tanısında yardımcı bir test olarak kullanılabilirliğini ortaya
koymuştur.
