Molecular detection of bovine coronavirus in the environment of a naturally infected dairy cattle herd.

What it found
Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.
The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.
The trial behind it
Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
Bovine coronavirus (BCoV) causes neonatal diarrhea and respiratory diseases in cattle. Detection of BCoV on surfaces and fomites in dairy facilities is rarely reported. We examined the presence of BCoV on various surfaces of a dairy farm with previous BCoV-positive cattle. A total of 61 samples were collected, including 37 samples of surfaces and fomites from the housing of suckling calves, weaned calves, heifers, and lactating cows. Fecal samples (n = 13) and nasal secretions (n = 11) were collected from calves and cows. Molecular identification of BCoV was performed using semi-nested RT-PCR. Amplicons of BCoV genes N and S1 from three positive samples (environment, diarrheic feces, and nasal secretions) were selected for nucleotide (nt) sequencing analysis. BCoV RNA was detected in 27% (10/37) of environmental samples, including wooden surfaces, concrete and tiles, plastic feed troughs, drinkers, and calf bottles. Furthermore, BCoV RNA was amplified in 46.1% of fecal and 36.4% of nasal secretion samples. Analysis of the N gene revealed 100% nt similarity between strains from different sources, while the S1 gene showed 99.7 to 99.8% similarity. The same BCoV strain was detected in cattle and on the evaluated surfaces. These strains were ancestrally different from the prototype strains but clustered with other Brazilian field strains. In conclusion, BCoV is present in cattle and on different surfaces within the environment of the evaluated dairy cattle farm. Biosecurity measures, such as cleaning and disinfection, are crucial to mitigate infection risk, especially for calves.
