TLDR
All extracts and fractions displayed considerable general toxicity towards brine shrimps, and exhibited low to moderate levels of anti-bacterial activity against most of the test strains.Abstract:
The extracts of the aerial parts of Polygonum barbatum var. barbata and Polygonum stagninum (Family: Polygonaceae) were assessed for anti-bacterial activity against a number of bacterial strains using the disc diffusion assay, and brine shrimp toxicity using the brine shrimp lethality assay. All extracts/fractions, except the MeOH extract/fraction, exhibited low to moderate levels of anti-bacterial activity against most of the test strains (zone of inhibition = 7-21 mm). All extracts and fractions displayed considerable general toxicity towards brine shrimps. The LD 50 values of the test extracts/fractions were within the range of 2.19 to 114.81 mg/mL, whereas that of the positive control (vincristine sulphate) was 0.61 mg/mL.read more

Antibiotic susceptibility testing by a standardized single disk method.
TL;DR: Recommendations of the National Committee for Clinical Laboratory Standards continue to be based on this publication; the “Kirby-Bauer” method is, among the many disk methods used in other countries, still the one that has been researched most thoroughly and updated continuously.
