Novel antigens expressed by Aeromonas salmonicida grown in vivo.
Article in Infection and immunity, 1993. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 2 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
Virulent and avirulent Aeromonas salmonicida strains grown inside intraperitoneal implants in Rainbow trout (Oncorhynchus mykiss) were examined for unique antigen expression. Western blots (immunoblots), performed with immune rabbit serum raised against in vivo-grown cells, revealed several unique antigens. With the exception of lipopolysaccharide (LPS), these novel antigens were destroyed after proteinase K treatment. The majority of these antigens were not induced in vitro in response to either iron limitation or anaerobiosis. In addition, electron microscopy demonstrated the presence of a putative capsule on in vivo-grown cells. Purification and fractionation of this carbohydrate material from cells grown in carbon-rich synthetic media resulted in the isolation and separation of an antigenically distinct LPS not seen with cells grown in standard media. Antiserum raised against in vivo-grown cells recognized both this LPS and the typical LPS of A. salmonicida apparent in in vitro-grown cells. Antiserum raised against in vitro-grown cells recognized only the LPS expressed in vitro. Antiserum directed against in vivo-grown cells was approximately 10 times more sensitive than serum directed against in vitro-grown cells in detecting A. salmonicida in infected fish kidney tissue.
