Antimicrobial resistance patterns of Klebsiella isolates from clinical samples in a Saudi hospital

Klebsiella infection is often the leading cause of morbidity and mortality. Resistance pattern of antimicrobial susceptibility to commonly prescribed drugs were studied in Klebsiella isolates from a hospital in Madinah, Saudi Arabia. Clinical samples were collected from 6840 patients and screened for Klebsiella species over a period of 14 months. The strains were identified using microbiological and biochemical tests...

Effectiveness of Pseudomonas species in the management of tomato early blight pathogen Alternaria solani

Management of tomato early blight pathogen (Alternaria solani) has relied principally on application of synthetic fungicides. The use of biological control agents has been recognized as a viable option to synthetic chemicals in plant disease control. The present study evaluated the effects of Pseudomonas fluorescens, P. aeruginosa, P. putida, and P. cepacia on tomato early blight pathogen and investigated their efficacy...

Determination of minimum inhibitory concentration (MIC) and minimum bactericidal concentration (MBC) using a novel dilution tube method

A novel ‘dilution tube method’ (DTM) which is a modification of the ‘dilution method’ (DM) is hereby described for the determination of minimum inhibitory concentration (MIC) and minimum bactericidal concentration (MBC). This new DTM uses only broth medium in tubes and the required antibiotic. MIC and MBC for Escherichia coli, Klebsiella pneumoniae and Staphylococcus aureus were determined in...

Promising biosurfactant produced by a new Candida tropicalis UCP 1613 strain using substrates from renewable-resources

The current work aimed to use agro-industrial wastes as a strategy to obtain biosurfactant from a new Candida tropicalis UCP 1613 isolated from mangrove sediments of Rio Formoso, Pernambuco State, Brazil. The yeast was identified based on 18S rRNA sequencing method and blast homology search. The promising strain showed the ability to use an optimal composition of a cheap medium containing whey (3%), cassava wastewater...
