Achillea micrantha Extract as antimicrobial agent

By Asma Naqi

The composition of detectable small organic compounds in the ethanol extract of Achillea micrantha was defined by means of gas chromatography-mass spectrometric analysis. There were 71 low molecular weight organic compounds observed, two of which remained unidentified. The antibacterial activity of the extract was studied in respect to Escherichia coli, Staphylococcus aureus, Pseudomonas aeruginosa using the agar diffusion test and serial dilutions to define minimum inhibitory concentration. In order to compare the antibacterial activity of the herb and blossom truss extract of A. micrantha, the extracts of A. millefolium and A. leptophylla was used. In relation to the microorganisms tested, a significant inhibitory effect was observed with the aqueous alcoholic extract of A. micrantha at the minimum inhibitory concentration of 0.05 µg/ml.

HIV remission achieved in second patient

A second person has experienced sustained remission from HIV-1 after ceasing treatment, reports a paper led by researchers at UCL and Imperial College London. The case report, published in Nature and carried out with partners at the University of Cambridge and the University of Oxford, comes ten years after the first such case, known as the ‘Berlin Patient.’ Both patients were treated with stem cell transplants from donors carrying a genetic mutation that prevents expression of an HIV receptor CCR5. The subject of the new study has been in remission for 18 months after his antiretroviral therapy (ARV) was discontinued. The authors say it is too early to say with certainty that he has been cured of HIV, and will continue to monitor his condition. “At the moment the only way to treat HIV is with medications that suppress the virus, which people need to take for their entire lives, posing a particular challenge in developing countries,” said the study’s lead author, Pro...
