Germination and proliferation of emetic Bacillus cereus sensu lato strains in milk.
Article in Folia microbiologica, 2013. 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
The Bacillus cereus sensu lato group includes potentially pathogenic bacteria that are ubiquitous in the environment and, importantly, could also be present in food products. This study focuses on emetic isolates which presumably could cause acute food poisoning and emetic syndrome. Here, we evaluate the ability of psychrotolerant Bacillus weihenstephanensis MC118 (isolated from soil) and mesophilic B. cereus BOD3/9 isolated from milk to germinate and multiply at 7 and 30 °C. Whereas the rates of germination at 30 °C in milk and nutrient broth of MC118 and BOD3/9 were similar, MC118, but not BOD3/9, proliferated to achieve relatively high numbers (∼10(6) colony-forming units/g) within 7 days of incubation at 7 °C. Mesophilic BOD3/9 showed a slight decrease of cell concentration in similar studies at 7 °C. Genotyping with repetitive extragenic palindromic sequence-based PCR and pulsed field gel electrophoresis revealed significant similarities between BOD3/9 and emetic reference B. cereus F4810/72 strain, while the B. weihenstephanensis MC118 isolate was more similar to the B. weihenstephanensis non-emetic reference DSMZ11821 strain. Our data suggest that emetic isolates that are also psychrotolerant, such as MC118, could constitute a hazard in the dairy industry, where milk could be a suitable medium for germination and growth.
