| Abstract |
Coxiella burnetii is the etiologic agent of Q fever, a zoonotic disease causing influenza-like illness, pregnancy loss, cardiovascular disease and chronic fatigue syndrome in people. C. burnetii is considered to be enzootic in ruminants, but clinical signs of infection do not always manifest. National studies have documented the presence of C. burnetii in dairy herds in Indiana. This represents an opportunity to better characterize the distribution and prevalence of C. burnetii infection at the state scale, allowing evaluation of the need for surveillance and response planning to occur at this level. A cross-sectional study was conducted to estimate the herd prevalence of C. burnetii in commercial cattle dairies in Indiana and characterize the strains of C. burnetii within these dairies. Bulk tank milk samples were collected between June and August of 2011 by the Indiana State Board of Animal Health (ISBOAH). A total of 316 of these samples were tested for the IS1111 transposon of C. burnetii using quantitative real time polymerase chain reaction (PCR). Single nucleotide polymorphism (SNP) genotyping was used to identify the multispacer sequence genotypes (ST) present in samples where the IS1111 transposon was identified. The geographic distribution of dairies testing positive for C. burnetii DNA and the identified STs were also evaluated. The estimated overall herd prevalence for C. burnetii DNA was 61.1 % (95 % CI 55.6-66.3 %). The highest estimated regional prevalence was 70.2 % in the Central region of Indiana. An ST was identifiable in 74 of the positive 178 samples (41.6 %) and none of the 10 negative samples tested. Of these samples, 71 (95.9 %) were identified as ST20, 2 (2.7 %) as ST8 and a combination of ST20 and ST8 was identified in a single sample. C. burnetii is present in dairy herds throughout Indiana. Indiana follows national trends with ST20 most commonly identified. The presence of multiple STs in a single bulk tank sample indicates that multiple strains of C. burnetii can circulate within a herd. This supports potential transmission of C. burnetii between goats and cattle, presenting the potential for a switch in the dominant genotype found in a given species. |

Attention Score in Context
This research output has an Altmetric Attention Score of 1. This is our high-level measure of the quality and quantity of online attention that it has received. This Attention Score, as well as the ranking and number of research outputs shown below, was calculated when the research output was last mentioned on 08 August 2015.
All research outputs
#20,286,650
of 22,821,814 outputs
Outputs from BMC Veterinary Research
#2,417
of 3,050 outputs
Outputs of similar age
#220,960
of 264,084 outputs
Outputs of similar age from BMC Veterinary Research
#61
of 75 outputs
Altmetric has tracked 22,821,814 research outputs across all sources so far. This one is in the 1st percentile – i.e., 1% of other outputs scored the same or lower than it.
So far Altmetric has tracked 3,050 research outputs from this source. They receive a mean Attention Score of 3.8. This one is in the 1st percentile – i.e., 1% of its peers scored the same or lower than it.
Older research outputs will score higher simply because they've had more time to accumulate mentions. To account for age we can compare this Altmetric Attention Score to the 264,084 tracked outputs that were published within six weeks on either side of this one in any source. This one is in the 1st percentile – i.e., 1% of its contemporaries scored the same or lower than it.
We're also able to compare this research output to 75 others from the same source and published within six weeks on either side of this one. This one is in the 1st percentile – i.e., 1% of its contemporaries scored the same or lower than it.
