“…These differences might stem from different climates, geographic location, sample size, year, species screened, and the cut-off value. 20,25 Previous studies 17,18,23 carried out in different provinces in eastern Anatolian region of Turkey showed that there has been an increase up to 14.8% in Q fever seroprevalence in cattle herds during the last decade. This increase may continue according to our result (19.4%) in the same region as well.…”

“…3 In the last two decades, several epidemiological studies on Q fever have been conducted in ruminant herds in Turkey. [20][21][22][23][25][26][27] Detection of specific antibodies is a useful indication of recent infections and previous exposure. ELISA is recommended to detect these disease indications as a practicable and highly sensitive test.…”

“…16 Several studies which investigated cattle seroprevalence led to results varying between 5.8%-20%. [17][18][19][20][21][22][23] Regarding these results, farm animals' exposure to C. burnetii i s considerably high in different part of Turkey. These domestic ruminants are also considered to be the major sources of human infection.…”

Objective: The aim of this study is to investigate Q fever seroprevalence in cattle in Turkey. Q fever is a highly infectious zoonotic disease which is caused by Coxiella burnetii and which has occurrence in many countries of the world. As it is a multiple species disease, many different domestic and wild animals could be the carrier of the pathogen. However, cattle, sheep and goats are the main reservoirs and the disease generally appears with an increase in the cases of abortion and stillbirth. Methods: Enzyme linked immunosorbent assay (ELISA) is preferred and recommended for the diagnosis of Q fever because they are highly sensitive and easy to use. In this study, blood samples of cattle randomly collected from 22 provinces of Turkey between 2017-2018 were tested by ELISA. Results: Among 1114 blood samples analyzed, the detected seropositivity level is 18% and provincial seropositivity is between 2.3%-35.2%. Regional results are close to each other changing between 15.1% and 22.3%. Conclusion:The results gathered have revealed the C. burnetii exposure of cattle in different regions of Turkey.The findings of this study display the necessity of strategies against this disease which poses hazards for both public and animal health. Since this disease leads to serious loss in animal production, determination of the fighting strategies against Q fever and evaluation of the methods after practice is important. This study is believed to contribute to the fight against this disease with the leading and comparable data it presents.

“…In the present study, 6% (n=4) of 66 sheep's milk and 0.6% (n=2) of 328 vaginal swabs from goats yielded C. burnetii DNA. In a study performed in Turkey, out of the 350 bovine milk samples and 250 ovine milk samples collected, 1,42% and 0,4% were found to be positive using the PCR technique, respectively 24 .

Objective. The aim of this study was to provide molecular evidence of C. burnetii in sheep and goats from some herds of Valledupar, Cesar, Colombia. Materials and methods. Fifteen herds of sheep and goats were chosen by convenience to investigate the infection by C. burnetii, during March and April of 2013. 328 female goats and 66 sheep from 15 herds were included in this study. Milk from ewes and vaginal mucus samples from goats were analyzed by Polymerase Chain Reaction for DNA detection of transposase gene (IS1111) of C. burnetii. Results. DNA of C. burnetii in 6% (4/66) of sheep's milk and 0.6% (2/328) vaginal mucus from goats was found. 13% (2/15) of the herds had at least one infected animal. Discussion. Our findings suggest the circulation of C. burnetii in sheep and goats from some herds of Valledupar, Colombia, and it highlights the possibility of occurrence of infections in humans and animals. Conclusions. The detection of C. burnetii in sheep milk could represent a public health risk factor for people who consuming raw milk, cheeses or people associated to agriculture and livestock handling. Further studies are necessary to evaluate other routes such as tick's bite, feces, milk from goats and vaginal mucus from sheep of this region of Colombia.

Although molecular prevalence rates of C. burnetii in sheep and cattle have been reported from many regions in Turkiye (Can et al 2015;Gulmez Saglam and Sahin 2016), to the best of our knowledge, there is limited data on the molecular prevalence of C. burnetii in the BTM in Turkiye (Can et al 2015).…”

Coxiella burnetii is the aetiological agent of Q fever, which is highly prevalent in Turkiye, but information on the genetic profiles of the bacterium is limited. This study aimed to investigate the presence of C. burnetii in bovine bulk tank milk (BTM) samples by polymerase chain reaction (PCR) and to investigate the genotypes by means of multiple-locus variable-number tandem repeat analysis (MLVA). A total of 25 markets that sold raw cow's milk were analysed by conventional PCR analysis. An MLVA analysis was performed at six loci, namely MS23, MS24, MS27, MS28, MS33, and MS34, to determine the genotypic variations of C. burnetii found in the positive DNA samples. The DNA of C. burnetii was detected in 16% of the BTM samples. The C. burnetii strains identified in the bovine milk samples collected in this study were found to belong to the same genotypic group as those detected in the bovine milk samples gathered in Greece. As a result, both the presence and genotyping studies of C. burnetii on the BTM samples in Turkiye will contribute to the determination of the geographical distribution of the agent.
