Characterization and proteome analysis of inosine 5-monophosphate dehydrogenase in epidemic Streptococcus suis serotype 2.
Article in Current microbiology, 2014. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 3 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
Streptococcus suis serotype 2 (SS2) is an important zoonotic pathogen that causes severe disease symptoms in pigs and humans. In the present study, we found one isogenic mutant lacking inosine 5-monophosphate dehydrogenase (IMPDH) ΔZY05719 was attenuated in pigs compared with the wild-type SS2 strain ZY05719. Comparative proteome analysis of the secreted proteins expression profiles between ZY05719 and ΔZY05719 allowed us to identify Triosephosphate isomerase (TPI) and glyceraldehyde phosphate dehydrogenase (GAPDH), which were down expressed in the absence of the IMPDH. Both of them are glycolytic enzymes participating in the glycolytic pathway. Compared with ZY05719, ΔZY05719 lost the ability of utilize mannose, which might relate to down expression of TPI and GAPDH. In addition, GAPDH is a well-known factor that involved in adhesion to host cells, and we demonstrated ability of adhesion to HEp-2 and PK15 by ΔZY05719 was significantly weakened, in contrast to ZY05719. The adhesion to host cells is the crucial step to cause infection for pathogen, and the reduction adhesion of ΔZY05719, to some extent illustrates the attenuated virulence of ΔZY05719.
