Two lactose-fermenting Salmonella typhi strains were isolated from bile and blood specimens of a typhoid fever patient who underwent a cholecystectomy due to cholelithiasis. One lactose-fermenting S. typhi strain was also isolated from a pus specimen which was obtained at the tip of the T-shaped tube withdrawn from the operative wound of the common bile duct of the patient. These three lactose-...

The gammaproteobacterium Xenorhabdus nematophila is a blood pathogen of insects that requires the CpxRA signal transduction system for full virulence (E. E. Herbert et al., Appl. Environ. Microbiol. 73:7826-7836, 2007). We show here that the DeltacpxR1 mutant has altered localization, growth, and immune suppressive activities relative to its wild-type parent during infection of Manduca sexta in...

The present study was aimed at purification and characterization of α-amylase enzyme from strain of Aspergillus niger isolated from local soil samples. Solid state fermentation (SSF) was carried out to produce α-amylase from A. niger using waste banana peel as substrate. The maximum activity of α-amylase (11926 U/gds) was recorded after 72 hours of fermentation. The extracted enzyme was subject...

Reservoir characterization of W-field, onshore Niger Delta was carried out using petrophysical evaluation well logs. Three reservoir sand intervals (A, B, C) were identified and correlated across four wells (W1, W2, W3, W4) in W-field the gamma ray, while fluid identification each achieved resistivity log. The C interval selected utilized for interpretation penetrated at depths 11741-11945ft, 1...

Aeromonas hydrophila, a widespread bacterium in the aquatic environment, causes hemorrhagic septicemia in fish. In the last decade, the disease has caused mass mortalities and tremendous economic loss in cultured fish. The complement component C7 is a terminal component of complement that interacts in a sequence of polymerization reactions with other terminal complement components to form a mem...

BACKGROUND Explicit recall (ER) is evident in approximately 0.2% of patients given general anaesthesia including muscle relaxants. This prospective study was performed to evaluate if cerebral monitoring using BIS to guide the conduction of anaesthesia could reduce this incidence significantly. PATIENTS AND METHODS A prospective cohort of 4945 consecutive surgical patients requiring muscle rel...
