The Five Different Bacteria
Words • 656
Pages • 3
Five different bacteria were isolated with 24.5% prevalence rate. The bacteria isolated include Klebsiella pneumoniae (37.93%), Pseudomonas aeruginous (31.04%), Escherichia coli (17.24%), Citrobacter freundi (6.89%) and Acinetobacter species (6.89%). This is similar to the study carried by Linet et al (2007), where K. pneumonia followed by P. aeruginosa were the most common Gram-negative bacilli isolated from LRTIs. Klebsiella pneumoniae, Pseudomonas aeruginous and Escherichil coli were reported each by Salami et al (2006) when immunity was severely compromised. But this result…...

Over the recent years besides the traditional ECL systems such as luminol-H2O2 and Ru(bpy)32+- tripropylamine, the new ECL luminophores based on nanomaterials including CdSe, CuS, MoS2-CdS, CeO2 and CdS have been used to developing sensitive biosensors. Accordingly, yang and co-workers developed a signal-switchable electrogenerated chemiluminescence aptasensor based on ferrocene-graphene sheets (Fc-GNs) for high-efficiency quenching of ECL from Au nanoparticles functionalized cadmium sulfide flower-like three dimensional (3D) assemblies (Au-CdS flowerlike 3D assemblies) for sensitive detection of prostate specific antigen (PSA).
