Detection of extended-spectrum beta-lactamases (ESBLs) in clinical isolates of Klebsiella pneumoniae using the ESBL NDP test and flow cytometric assay in comparison to the standard disc diffusion

This study was undertaken to evaluate the comparison among three different assays: extended-spectrum beta-lactamases (ESBL) Nordmann/ Dortet/ Poirel (NDP) test, flow cytometric assay and disc diffusion method for the detection of ESBL production. Sixty clinical isolates of Klebsiella pneumoniae were isolated from patients’ clinical samples admitted to Suez-Canal University Hospital, Ismailia Governorate. The...

Effects of lithium compounds on the growth of white-rot fungi

Identifying the most suitable lithium compounds for fungal growth is important for the lithium (Li) enrichment of mushrooms. However, enrichment thus far has been carried out using LiCl. In an effort to identify an alternative source of lithium, we investigated the effect of five lithium compounds on lag phase, growth rate and biomass of ten species of white-rot fungi. The objective of this work was to make a screening...

Microbiological load of yoghurt sold in Omoku schools, Rivers State, Nigeria

Sachets of various brands of yoghurt were randomly purchased from different retail outlets within Omoku schools and its pH and microbiological quality were determined using standard method. Total bacterial count (TBC) and Coliform count were done using standard plate count method after making serial dilutions of yoghurt samples. Nutrient agar (NA) was used for enumeration of TBC. NA plates were incubated at 37°C for...
