This study has shown that the results from Q fever micro-immunofluorescence vary according to the center in which they are carried out. This has implications for the interpretation of such tests, raises questions regarding the validity of using serological criteria alone as a means of diagnosing ...
Q fever is a newly discovered disease in Japan. Previously it was considered completely absent. Knowledge of the illness is thus limited. Available epidemiological data consists frequently of small samples of animals or humans rendering the interpretation poorly accurate. The lack of knowledge of the...
For the analysis of the geographical distribution of Q fever, various factors were investigated. No male sheep was seropositive but 19.2% of the male goats had anti-C. burnetiiantibodies. The risk to attain the pathogen was greater in female goats as compared to female sheep (Table4). The ...
Normal cutoff titers for Q fever and rickettsial serology were 1/25 and 1/128, respectively. However, as we were screening in a previously undescribed area of infection, a more conservative approach was undertaken to enhance the specificity of the assays. Therefore, the lowest titers considered ...
It is not currently clear which source laboratories include Q fever in their serology screens for atypical pneumonia, a policy that could vary geographically. There may be greater awareness of Q fever in the southwest region than elsewhere, and a laboratory survey would aid in understanding ...
A Q fever outbreak on a dairy goat and cattle farm was investigated with regard to the One Health concept. Serum samples and vaginal swabs from goats with different reproductive statuses were collected. Cows, cats, and a dog were investigated with the same sample matrix. The farmer’s family...
