A metabolic enzyme as a primary virulence factor of Mycoplasma mycoides subsp. mycoides small colony.
Article in Journal of bacteriology, 2005. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 85 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
During evolution, pathogenic bacteria have developed complex interactions with their hosts. This has frequently involved the acquisition of virulence factors on pathogenicity islands, plasmids, transposons, or prophages, allowing them to colonize, survive, and replicate within the host. In contrast, Mycoplasma species, the smallest self-replicating organisms, have regressively evolved from gram-positive bacteria by reduction of the genome to a minimal size, with the consequence that they have economized their genetic resources. Hence, pathogenic Mycoplasma species lack typical primary virulence factors such as toxins, cytolysins, and invasins. Consequently, little is known how pathogenic Mycoplasma species cause host cell damage, inflammation, and disease. Here we identify a novel primary virulence determinant in Mycoplasma mycoides subsp. mycoides Small Colony (SC), which causes host cell injury. This virulence factor, released in significant amounts in the presence of glycerol in the growth medium, consists of toxic by-products such as H2O2 formed by l-alpha-glycerophosphate oxidase (GlpO), a membrane-located enzyme that is involved in the metabolism of glycerol. When embryonic calf nasal epithelial cells are infected with M. mycoides subsp. mycoides SC in the presence of physiological amounts of glycerol, H2O2 is released inside the cells prior to cell death. This process can be inhibited with monospecific anti-GlpO antibodies.
