Mechanism of antibacterial activity of diallyl sulfide against Bacillus cereus.
Article in Journal of Ayurveda and integrative medicine. 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
World health organization (WHO) recognizes antimicrobial resistance as a silent pandemic. It is estimated that 10 million deaths will occur annually due to antimicrobial resistant infections by 2050. Phytochemicals exhibit activity against drug resistant bacteria, offering potential for developing novel antibacterial agents. Garlic organosulphur compounds exhibit potent activity against a variety of drug-resistant bacteria. Identifying their mechanism of action is critical to assess their potential to be developed as novel antibacterial agents. Diallyl sulfide (DAS) is a component of garlic essential oil with antibacterial activity. In this study antibacterial activity of DAS was investigated against Bacillus cereus, a common foodborne pathogen. DAS exhibited activity against B. cereus with a minimum inhibitory concentration (MIC) of 54.75 mM. The presence of DAS significantly reduced the growth of B. cereus. The study also investigated the mechanism of antibacterial activity of DAS against B. cereus. Treating B. cereus with sub-MIC and MIC concentration of DAS resulted in a dose and time-dependent leakage of intracellular proteins. The protein leakage was enhanced at acidic pH. Scanning electron microscopy (SEM) of B. cereus treated with DAS showed deformation in the cell membrane. Thus, the data indicate that DAS exerts its antibacterial activity by compromising the membrane integrity of B. cereus. The study demonstrates DAS could be used to control B. cereus infections. The findings indicate that DAS has a membrane altering activity, suggesting that development of resistance to this mechanism is less likely and the compound could be novel antibacterial or a good adjuvant for antibiotics.
