Q fever is one of the commonest infectious diseases worldwide. A Coxiella burnetii prevalence of 97.6% has been found by ELISA and PCR tests of the bulk tank milk in dairy cattle farms of Hungary. The herd- and individual-level seroprevalence rates of C. burnetii in the examined dairy cows and farms have dramatically increased over the past ten years. Three high-producing industrial dairy farms were studied which had previously been found ELISA and PCR positive for C. burnetii by bulk tank milk…

Presence of Coxiella burnetii in dairy cattle and farms in the Czech Republic.

The aims of this study were to evaluate the prevalence of Coxiella burnetii on both herd and animal level based on ELISA and PCR tests. Antibodies to C. burnetii were detected in 22 out of the 24

Serological survey of Coxiella burnetii infections in dairy cattle, sheep, goats and zoo animals in Hungary - Short communication.

TLDR
The aim of this large-scale study was to demonstrate the importance of Q fever in different species as a possible source for human infection in most regions of Hungary.

Infertility in dairy cows – Possible bacterial and viral causes

TLDR
Although no statistical correlation could be demonstrated between the severity of histological lesions of the endometrium and the uterine pathogenicity of the bacteria (P = 0.8555), endometritis of a certain severity grade and/or a recognised or potential uterine Pathogen were found in all samples.

Prevalence of Coxiella burnetii in bovine placentas in Hungary and Slovakia: Detection of a novel sequence type - Short communication.

TLDR
The high C. burnetii DNA load found in retained fetal membranes may be a potential risk factor for human infection and may also be associated with the retention of fetal membranes.

TLDR
The aim of this study was to assess the importance and potential infectious sources of Q fever in Hungary and the real-time PCR examination of 5402 ixodid ticks collected from different parts of the country yielded negative results.

Coxiella burnetii in Infertile Dairy Cattle With Chronic Endometritis

TLDR
Investigation of uterine biopsies from dairy cattle with poor fertility identified the presence of intralesional and intracytoplasmic C. burnetii in macrophages in the endometrium of cattle for the first time, and revealed endometritis admixed with perivascular and periglandular fibrosis.

Prevalence of Coxiella burnetii infections in aborted fetuses and stillborn calves

TLDR
It is indicated that C burnetii infections are detected in a limited percentage of aborted fetuses and stillborn calves by IHC, and the importance of placentas with PCR-positive and IHC-negative test results is needed.

Coxiella burnetii associated reproductive disorders in domestic animals-a critical review

TLDR
There is a strong need to validate non-pathology based methods such as polymerase chain reaction for their use in diagnostic and research in relation to establishing C. burnetii as the cause of abortion and to adapt an appropriate study design and include adequate control animals when linking epidemiological findings to C. burningetii.

Early detection of pregnancy and embryonic loss in dairy cattle by ELISA tests.

TLDR
The authors conclude that BioPRYN was useful for prediction of a part of LEL in dairy cows and serum P4 concentration in these cows related to the rate of L EL.

Does Coxiella burnetii affect reproduction in cattle? A clinical update.

TLDR
The effects of C. burnetii infection or Q fever disease on the reproductive behaviour of dairy cattle are reviewed, with special emphasis placed on the scarcity of data available and possible control actions discussed.
