Evolution of Antifungal Activity of Artemisia herba-alba Extracts on Growth of Aspergillus sp. and Rhizopus sp.

Published on: 11th February, 2025

Plant extracts and their constituents have a long history as antifungal agents, but their use in biotechnology as preservatives, due to the increasing resistance of fungi to fungicides, has been rarely reported in Libya. The aim of this study is to evaluate the antifungal activity of ethanol extract and water extract of the wild native plant Artemisia herba-alba against two genera of mold fungi Aspergillus sp. and Rhizopus sp. This mold fungal causes significant damage to crops in the field or during storage. In this study, a hot ethanol extract was prepared using a device Soxhlet, and water extract hot as well as a cold ethanol extract and cold-water extract aqueous extract three concentrations (25% - 50% - 75%) of plant extracts were used on the tested fungi. All extracts showed an effect on the tested fungi. The concentrations of (75% - 50%) of the extracts had an effect on the tested fungi, while most concentrations of 25% of the extracts did not record any effect on the tested fungi. The hot ethanol extract of the Artemisia herba-alba plant was more effective than the other extracts. Aspergillus sp. was recorded with the highest inhibitory zone (0.73 mm).

Cancer Cell Resistance: The Emergent Intelligence of Adaptation and the Need for Biophysical Integration

Published on: 16th May, 2025

Cancer has long been recognized as a complex, multifactorial disease, in which genetic mutations and epigenetic alterations drive unchecked proliferation, tissue invasion, and metastasis.

The Bacteriological Profile of Nosocomial Infections at the Army Central Hospital of Brazzaville

Published on: 25th November, 2025

Nosocomial infections are infections acquired during a stay in a healthcare facility, representing a major public health challenge worldwide, and particularly in Africa, due to their frequency, potential severity, and associated costs. In Congo, their epidemiological profile is not yet well understood. It’s in this context that we undertook to conduct a retrospective descriptive study on nosocomial infections between January 1, 2012, and December 31, 2016, in the internal medicine department of the Army Central Hospital of Brazzaville, in order to analyze the bacteriological profile of nosocomial infections.The study involved 189 patients. The results revealed that hospital-acquired infections were frequent, with a female predominance (71.43%), an average age of 32 years, and risk factors including self-medication with antibiotics (51%) and urinary catheterization (39%). Urinary tract infections were the most common (57%), with Escherichia coli as the main pathogen (17%), and mortality from these infections reached 53%.The study highlighted a high mortality rate linked to hospital-acquired infections, primarily associated with HIV status and self-medication. Management, prevention, and infection control measures, including improved antibiotic stewardship, are necessary to reduce mortality.
