Variations in structural and plasmid profiles of starved Shigella in seawater

In this study, we incubated three strains of Shigella (Shigella sonnei (S1), Shigella boydii(S2) and Shigella flexneri (S3)) in seawater microcosms (at room temperature and at 4°C) for eight months and we studied the modification of the proteins secreted, cytosolicand inner membrane profiles and their composition in fatty acids. Plasmid profiles were also...

Effect of biological treatment and ultraviolet (UV)-C radiation disinfection process on wastewater bacterial community as assessed by denaturing gradient gel electrophoresis (DGGE) fingerprints

The rotating biological contactor (RBC) process was frequently used for the biological wastewater treatment in order to remove pollutants and to improve the water qualitybefore discharge to the environment. The presence of bacteria species in the secondary treated wastewater indicates the necessity of a tertiary treatment process [ultraviolet (UV)-C radiation disinfection] to reduce the number of living...

Genetic diversity of bovine viral diarrhoea virus in Beijing region, China from 2009 to 2010

The genetic diversity of bovine viral diarrhea viruses (BVDV) from Beijing region, China between 2009-2010, was investigated using a phylogenetic analysis of partial 5’untranslated region (5’UTR) nucleotide sequences from 61 BVDV positive samples, and for 13 selected samples, the Npro region was also investigated. All the sixty-one blood samples were collected...

Microbial pollution of the Mezam river system and its health impact in Bamenda (North-West Cameroon)

A two-year study was carried out from June 2009 to May 2011 to investigate the microbial quality of the Mezam river system in Bamenda and its health impact, given the prevalence of waterborne diseases among the population who use the river water for various purposes, notably domestic and agricultural activities. River, spring and tap water samples were collected monthly and analysed quantitatively for faecal bacteria...

The plant growth promoting bacterium Bacillus sp. CaSUT007 produces phytohormone and extracellular proteins for enhanced growth of cassava

Bacillus sp. strain CaSUT007, a plant growth promoting rhizobacterium isolated from cassava, was investigated for the secretion of compounds that might be involved in plant growth promotion. Extracts containing phytohormone and extracellular proteins were made from the cell-free fluid of CaSUT007 broth cultures. These extracts, along with a whole culture of CaSUT007 and the raw fluid and cellular fractions from a...

The possibility of using Sansevieria aethiopica (Thunb) leaf extracts in combinations with gentamicin for the treatment of oral enterococcal infections

Sansevieria aethiopica (Thunb) has been reported to be used for the treatment of oral infections in Eastern Cape of South Africa. Based on ethnobotanical survey, the plant was selected for the possible synergistic effects of its acetone, ethanol and methanolic extracts with gentamicin on the planktonic and sessile cells of Enterococcus faecalisATCC 29212 and Enterococcus faecalis KZN. In...

Using phenotypic based approaches to compare Escherichia coli isolates from human, livestock, fish and environmental sources within the Lake Victoria basin of Kenya

The study compares Escherichia coli recovered from human, fish products, domesticated animals and the environment within the Lake Victoria basin on the basis of their antimicrobial susceptibility profiles. A total of 134 E. coli isolates were isolated from the collected samples. 52.2% of the E. coli isolates were found to be resistant to at least one antibiotic. Isolates originating...

Evaluation of antibacterial activity of Laurus nobilis L., Rosmarinus officinalis L. and Ocimum basilicum L. from Northeast of Algeria

Rosmarinus officinalis L., Laurus nobilis L. and Ocimum basilicum L. are widespread herbs in Algeria. The essential oils of the three species were extracted from leaves by hydrodistillation. The yields were respectively 0.36, 0.6 and 0.71%. The aim of this study was to evaluate the antibacterial activity of these essential oils against twenty bacterial strains: Enterococcus...

Investigations on aflatoxigenic fungi and aflatoxins contamination in some nuts sampled in Algeria

In this study, 40 nuts samples (almonds, pistachios, hazelnuts, peanuts and walnuts) available in the Algerian market were investigated for aflatoxigenic fungi and aflatoxins contamination. An evaluation of mould biodiversity revealed Aspergillus link to be the most frequent genus, while species belonging to the section Nigri (30.6%) and to the sectionFlavi (27.9%) were predominantly isolated....

Production of oleoresin from ginger (Zingiber officinale) peels and evaluation of its antimicrobial and antioxidative properties

Dried ginger (ginger peel, peeled and unpeeled ginger) extracts were produced using acetone, and subjected to antimicrobial and anti-oxidative properties. In the antimicrobial assay using agar well  diffusion technique the extracts were inoculated with five different organisms (Escherichia coli, Staphylococcus aureus, Salmonella typhimurium, Aspergillus niger and Bacillus subtilis) at different...
