Cyclic depsipeptide producing fluorescent pseudomonads exerts antifungal activity against fungal pathogens of maize (Zea mays)
Cyclic lipopeptides (CLPs) with antibiotic, biosurfactant producing fluorescent pseudomonads were isolated from sugar beet-maize intercropped in sandy loam soils at Maize Research Station, Vagarai, TNAU. Approximately 20 fluorescent pseudomonads from sandy loam soils were isolated by using two different growth media. The strains were distinguished based on their growth, CFU/g, fluorescence, and pigment production....
Extended spectrum-Î²-lactamase producing Escherichia coli and Klebsiella pneumoniae causing urinary tract infection
Extended spectrum β-lactamase (ESBL) producing Escherichia coli and Klebsiella pneumoniae causing urinary tract infection (UTI) constitutes a significant therapeutic challenge. The aim of this study was to investigate the frequency of ESBL producing Escherichia coli and Klebsiella pneumoniae isolated from urine samples. Clinical isolates of multidrug resistant Gram negative rods (n=102) were taken from urine...
In vitro antimicrobial activity of three medicinal plants of Ethiopia against some selected bacterial isolates
Medicinal plants constitute natural source of antimicrobial drugs that will provide essential compounds to fight against disease. In this study, the antibacterial activity of ethanol extracts of Moringa stenopetala, Thymus serrulatus, and Terminalia brownii were investigated against selected pathogenic Gram positive and Gram negative bacteria. In vitro antibacterial activities of the ethanol extracts were tested at a...
Enteric fever caused by Salmonella enterica serovar paratyphi A: An emerging health concern in Nepal
Enteric fever is an invasive life-threatening systemic disease caused by the Salmonella enterica human-adapted serovars typhi and paratyphi. Increased incidence of infection with S. enterica serovar paratyphi A poses a significant health concern in some areas of the world. In this study, the incidence of enteric fever confirmed by isolation of Salmonella paratypi A or S. typhi from blood cultures of patients presenting...
Analysis of high levels of multidrug resistant Escherichia coli from healthy broiler chickens in Western Algeria
One hundred and two Escherichia coli strains isolated from healthy broiler chickens collected from April 2012 to November 2014 in seven geographic areas of western Algeria were studied. Susceptibility pattern to 11 antimicrobial agents was determined by disk diffusion method as recommended by the Clinical Laboratory Standard Institute (CLSI). Antibiograms revealed high levels of resistance to quinolones and...
