Molecular characterization of Shiga toxin-producing Escherichia coli isolated from the environment of a dairy farm.
Article in Current microbiology, 2012. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 12 papers.
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
Environmental samples were taken from ground, cattle water troughs, and feeders from a dairy farm with different STEC prevalence between animal categories (weaning calves, rearing calves, and dairy cows). Overall, 23 % of samples were positive for stx genes, stx(2) being the most prevalent type. Isolates were analyzed by PCR monoplex to confirm generic E. coli and by two multiplex PCR to investigate the presence of stx(1), stx(2), eae, saa, ehxA, and other putative virulence genes encoded in STEC plasmids: katP, espP, subA, and stcE. The toxin genes were subtyped and the strains were serotyped. The ground and the environment of the rearing calves were the sites with the highest number of STEC-positive samples; however, cattle water troughs and the environment of cows were the places with the greater chance of finding stx(2EDL933) which is a subtype associated with serious disease in humans. Several non-O157 STEC serotypes were detected. The serotypes O8:H19; O26:H11; O26:H-; O118:H2; O141:H-; and O145:H- have been asociated with human illness. Furthermore, the emergent pathogen STEC O157:H- (stx(1)-ehxA-eae) was detected in the environment of the weaning calves. These results emphasize the risk that represents the environment as source of STEC, a potential pathogen for human and suggest the importance of developing control methods designed to prevent contaminations of food products and transmission from animal to person.
