Editing Q fever (section)

=== Clinical signs ===
In contrast to humans, though a respiratory and cardiac infection could be experimentally reproduced in cattle,<ref>{{Cite journal|vauthors=Plommet M, Capponi M, Gestin J, Renoux G, Marly J, Sahuc D, Petit A|language=fr |title=FIÈVRE Q EXPÉRIMENTALE DES BOVINS|journal=Annales de Recherches Vétérinaires|oclc=862686843|year=1973|volume=4|issue=2|pages=325–346}}</ref> the clinical signs mainly affect the reproductive system. Q fever in ruminants is, therefore, mainly responsible for abortions, metritis, retained placenta, and infertility.

The clinical signs vary between species. In small [[ruminants]] (sheep and goats), it is dominated by abortions, premature births, stillbirths, and the birth of weak lambs or kids. One of the characteristics of abortions in goats is that they are very frequent and clustered in the first year or two after contamination of the farm. This is known as an abortion storm.<ref>{{cite journal | vauthors = Arricau-Bouvery N, Rodolakis A | title = Is Q fever an emerging or re-emerging zoonosis? | journal = Veterinary Research | volume = 36 | issue = 3 | pages = 327–349 | date = May 2005 | pmid = 15845229 | doi = 10.1051/vetres:2005010 | doi-access = free }}</ref>

In cattle, although abortions also occur, they are less frequent and more sporadic. The clinical picture is rather dominated by nonspecific signs such as placental retentions, metritis, and consequent fertility disorders.<ref>{{cite journal | vauthors = De Biase D, Costagliola A, Del Piero F, Di Palo R, Coronati D, Galiero G, Uberti BD, Lucibelli MG, Fabbiano A, Davoust B, Raoult D, Paciello O | display-authors = 6 | title = Coxiella burnetii in Infertile Dairy Cattle With Chronic Endometritis | journal = Veterinary Pathology | volume = 55 | issue = 4 | pages = 539–542 | date = July 2018 | pmid = 29566608 | doi = 10.1177/0300985818760376 | s2cid = 4268347 | doi-access = free }}</ref><ref>{{Cite web | vauthors = Valla G |title=Prevalenza di Coxiella burnetii nel latte di massa in allevamenti di bovine da latte italiani e possibile correlazione con problemi riproduttivi |url=https://www.vetjournal.it/images/archive/pdf_riviste/4649.pdf}}</ref><ref>{{Cite book | vauthors = Ordronneau S  |url= http://worldcat.org/oclc/836117348 |title=Impact de la vaccination et de l'antibiothérapie sur l'incidence des troubles de la reproduction et sur la fertilité dans des troupeaux bovins laitiers infectés par Coxiella Burnetii |oclc=836117348}}</ref>
