Hemolytic and nonhemolytic enterotoxin genes are broadly distributed among Bacillus thuringiensis isolated from wild mammals.

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
The presence of cytotoxin K (cytK), nonhemolytic (NHE), and hemolytic (HBL) enterotoxin genes was investigated in 74 Bacillus thuringiensis strains recovered from the intestines of wild mammals from northeast Poland, using polymerase chain reaction amplification and Southern hybridization. All the isolates harbored genes coding for toxin(s) that could cause diarrhea. The B. thuringiensis strains containing the nhe genes were found more frequently (nheA 100%, nheB 77%, nheC 96%) than those with the hblACD (74%) and cytK (73%) genes. The presence/absence of the nheA, hblA, and cytK genes was confirmed in all of the B. thuringiensis strains by Southern hybridization. Interestingly, these experiments also indicated that the nheA locus is located on a more variable chromosome region compared with hblA and, to a lesser degree, cytK. Detection of the 41-kDa component of NHE enterotoxin by the TECRA assay revealed various protein levels by B. thuringiensis strains. These results indicate the existence of environmental B. thuringiensis strains bearing the potential virulence arsenal for the production of diarrheal toxins, and emphasize the importance of small animals in the spread of B. cereus-like enterotoxin genes in nature. However, further investigation is needed to clarify any possible involvement of environmental B. thuringiensis strains in human health issues.
