Subtypes of intimin among non-toxigenic Escherichia coli from diarrheic calves in Brazil.
Article in Canadian journal of veterinary research = Revue canadienne de recherche veterinaire, 2000. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 4 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
One hundred and five strains of Escherichia coli that were isolated from calves with diarrhea in the state of São Paulo, Brazil, and were negative for enterotoxins and cytotoxins, were examined for the eae gene. Four (3.8%) strains were positive by polymerase chain reaction (PCR) and were shown to produce intimin by using Western blot with specific antiserum against the conserved N-terminal region of intimin. Subtyping of the intimins was done by PCR with specific primers and by Western blot with specific antisera against the C-terminal variable region of the protein. Three of these isolates (O?:H11, O26:H-, O123:H1) produced the beta subtype of intimin, and the 4th (0103:H2) produced intimin that was not typable. The 0103:H2 and the O26:H-isolates adhered to HEp-2 cells with diffuse adherence and localized-like adherence patterns, respectively. The other strains did not adhere to HEp-2 cells. To our knowledge, this is the first report of the occurrence of a subtype of intimin described for human enteropathogenic E. coli among bovine diarrheogenic E. coli. It is also the first report from Brazil demonstrating the presence of bovine E. coli harboring the eae gene.
