The use of Lycopersicum esculentum Mill. leaves extract against the survival of fungi

In this study, the antifungal fraction of Lycopersicum esculentum Mill. leaves extract was evaluated for its effect against biomass and cell viability of three strains of Aspergillus (Aspergillus fumigatus, Aspergillus flavus and Aspergillus nidulans). The results obtained show a reduction of the RNA concentration representing the biomass with the increase of the antifungal fraction content in the medium. Indeed, the...

AmpC beta-lactamase production among Pseudomonas aeruginosa and Proteus mirabilis isolates at the Komfo Anokye Teaching Hospital, Kumasi, Ghana

Extended spectrum β-lactamases (ESBLs) are frequently reported in Ghana, but AmpC bacteria reports are scanty. This study determines the prevalence of AmpC Pseudomonas aeruginosa and Proteus mirabilis clinical isolates at the Komfo Anokye Teaching Hospital (KATH), Kumasi, where ESBL and AmpC are not routinely tested. Non-duplicate 245 isolates comprising 187 (76.3%) P. aeruginosa and 58 (23.7%) P. mirabilis were...

Investigation of the antimicrobial and hemolytic activity of venom of some Egyptian scorpion

Leuirus quinquestriatus, Androctonus amoreuxi and Androctonus australis are venomous scorpion in Egypt. Their venom is complex mixture of salts, neurotoxins, peptides and proteins which has therapeutic applications, and can rapidly kill a broad range of microbes. Estimations of total proteins of the venom indicated that L. quinquestriatus had the highest value than the others (10.64 ± 0.04). Hemolytic activity of...
