Q Fever Outbreak among Workers at a Waste-Sorting Plant.

An outbreak of Q fever occurred in February-April 2014 among workers at a waste-sorting plant in Bilbao (Spain). The outbreak affected 58.5% of investigated employees, 47.

Genetic diversity and variation over time of Coxiella burnetii genotypes in dairy cattle and the farm environment.

The genetic diversity of Coxiella burnetii from 36 dairy cattle herds was determined by Multiple-Locus Variable number tandem repeats Analysis (MLVA), and genotypes from different sources (bulk-tank milk - BTM and surface dust) and sampling time (2009/10 and 2011/12) were compared. A total of 15 different genotypes were identified from 60 BTM and seven dust samples, including seven genotypes reported here for the first time (BN, BO, BP, BQ, BR, BS, BT). The two most prevalent genotypes (J and I), detected both in BTM and dust, accounted for 44.

Progression of Coxiella burnetii infection after implementing a two-year vaccination program in a naturally infected dairy cattle herd.

Background: The high prevalence of Coxiella burnetii infection in dairy cattle herds recently reported and the long survival time of the bacterium in the environment pose a risk to human and animal health that calls for the implementation of control measures at herd level. This study presents the results of a 2-year vaccination program with an inactivated phase I vaccine in a Spanish dairy herd naturally infected with C. burnetii.

Genotyping of Coxiella burnetii from domestic ruminants in northern Spain.

Background: Information on the genotypic diversity of Coxiella burnetii isolates from infected domestic ruminants in Spain is limited. The aim of this study was to identify the C. burnetii genotypes infecting livestock in Northern Spain and compare them to other European genotypes.
