Effect of tobacco tar on Staphylococcus aureus and Candida albicans biofilm formation
Twenty compounds were determined in the tar of cigarette smoke. The tar was obtained using tobacco filters and then analyzed by liquid chromatography-mass spectrometry (LC-MS). Tobacco tar expressed marked decrease in the susceptibility of Staphylococcus aureus to penicillin, tetracycline and amoxicillin/clavulanic antibiotics and showed marked decrease in susceptibility of Candida albicans to the tested antifungals...

In vitro cytotoxicity and biological activities of Genipa americana (Rubiaceae) ethanolic extracts
This study aimed to determine the in vitro toxicity of Genipa americana and its antiviral and anti-microbial activities. Due to lack of knowledge on G. americana validation as medicinal plant, biological studies were performed. For the cytotoxicity experiments, decreasing concentrations of ethanolic extracts of G. americana branches, fruits, and leaves were added to a confluent monolayer of Vero cells. After 72 h, it...

Inhibition of aflatoxin B1 production of Aspergillus flavus isolated from peanut seeds using Lycium halimifolium Mill leaves fractions
The aim of this study is to explore the impact of Lycium halimifolium Mill leaves extracts on mycotoxin B1 production in vitro, as well as the inhibitor effect of the aflatoxin B1 synthesis by Aspergillus flavus strain. The strain was isolated, identified (gi |146746162 | EF409803.1.) and positively tested for the production of Aflatoxin B1. The antimycotoxinogenesis effect was investigated using L. halimifolium Mill...
