ABSTRACT In this study, we report an outbreak of Salmonella enterica serotype Livingstone resistant to extended-spectrum cephalosporins that occurred in a neonatal ward the maternity department Farhat Hached Hospital, Sousse, Tunisia, 2002. A total 16 isolates were recovered from babies hospitalized during period 1 July. All these developed diarrhea, and three them septicemia. demonstrated resistance ceftriaxone ceftazidime due production β-lactamase (ESBL). The also aminoglycosides...
Color is one of the main problems in wastewater and many techniques can be applied to remove it. In present work, a pilot plant scale investigation was carried out optimize treatment efficiency order reduce amount residual adsorbed dye that will found waste sludge. For degradation textile (TWW), coagulation–flocculation experiments were performed jar test apparatus using FeCl3, Fe(SO4), Al2(SO4)3 Cu(SO4) as coagulant agent three bacteria (Sphingomonas paucimobilis, Bacillus sp. filamentous...
In the current study potential use of aqueous and methanolic extracts Ephedra alata aerial parts as biological control agent against pathogenic bacteria especially Staphylococcus aureus methicillin resistant isolated from auricular infections was evaluated. Chemical tests spectrophotometric methods were used for screening quantification phytochemicals. The assessment antioxidant activity accomplished by DPPH ABTS radicals scavenging assays. Extracts evaluated their antibacterial efficacy...
ABSTRACTThis study aimed to investigate the in vitro properties of lactic acid bacteria isolated from colostrum samples goat, sheep and cow. Four isolates identified through 16S rDNA sequencing were screened for probiotic potential including their enzymatic activities (hemolytic, DNase activity, API ZYM profiling tolerance gastrointestinal conditions), antimicrobial activities, adhesion biofilm formation capacity, auto-aggregation co-aggregation with pathogens hydrophobicity. They also...
Recurrent pregnancy loss (RPL) is a major reproductive problem that affects approximately 5% of couples. The objective this study was to assess vaginal flora dysbiosis in women suffering from unexplained RPL and investigate the pathogenic properties microbiota associated with aerobic vaginitis (AV). included one hundred fifteen women, 65 50 controls. diversity isolated evaluated by molecular sequencing. Then, factors, such as acid-resistance, antibiotics susceptibility, biofilm formation...
Microorganisms inhabiting fermented foods represent the main link between consumption of this food and human health. Although some is a reservoir potentially probiotic microorganisms, several are still unexplored. This study aimed at characterizing potential lactic acid bacteria isolated from zgougou, matrix consisting watery mixture Aleppo pine's seeds. In vitro methods were used to characterize safety, survival ability in typical conditions gastrointestinal tract, adherence capacity...
Scarce information about the phenolic composition of Scabiosa atropurpurea L. is available, and no carotenoid compounds have been reported thus far. In this study plant was both investigated associated bioactivities were evaluated. Aiming to obtain extracts volatile fractions known medicinal plants valorize them in pharmaceutical or food industries, two techniques extraction five solvents used determine biologically active compounds. Gas chromatography coupled flame ionization mass...
A 1-year prospective study in 2 paediatric outpatient clinics Sousse, Tunisia, aimed to determine the presence of group streptococci acute pharyngitis cases and carriers, distribution serotypes biotypes. Group were found 9.0% throat swabs from 155 controls 17.7% 474 patients (P < 0.05). Of 43 strains isolated submitted for typing, 15 different types identified, most common being M75 (14 strains; 32.5%), M9 (6 14.0%), M76 (5 11.6%) M12 (4 9.3%). Three non-typeable (7.0%). Biotyping showed 3...
Biosurfactants exhibit antioxidant, antibacterial, antifungal, and antiviral activities. They can be used as therapeutic agents in the fight against infectious diseases. Moreover, anti-adhesive properties several pathogens point to possibility that they might serve an coating agent for medical inserts prevent nosocomial infections, without using synthetic substances. In this study, antimicrobial, antibiofilm, cell surface hydrophobicity, antioxidative activities of biosurfactant extracted...
Abstract The effect of dietary Kefir supplementation on the biometric, biochemical, and histological parameters Nile tilapia ( Oreochromis niloticus ) exposed to aflatoxin B1 (AFB1, 200 µg/kg diet) contamination was studied. yeasts were dominant in followed by lactic acetic acid bacteria. showed relatively interesting antioxidant potential DPPH• (IC 50 = 0.9 ± 0.02 mg/ml) ABTS•+ 2.2 0.03 scavenging activities, Fe 3+ ‐reducing power (EC 0.5 1.2 0.01 mg/ml), β‐carotene bleaching assay 3.3...
The aim of the present study is to isolate, characterize and identify a novel strain ZC from Metlaoui phosphate laundries wastewater (MPLW). chemical characterization this rich effluent showed an alkaline pH saline, highly turbid in suspended matter total solids. MPLW samples were loaded with potentially toxic metals, presented decreasing order as follows: magnesium (5655 mg L−1), potassium (45 lead (1 iron (0.7 cadmium (0.5 copper (0.3 L−1) zinc (0.1 L−1). Due high COD/BOD5 ratio, poorly...
The positive impact of probiotic strains on human health is more evident than ever. To achieve the beneficial effects and desirable functional properties probiotics, sufficient numbers these microorganisms must reach intestinal tract with high survival rates. purpose this study was to identify characterize a novel strain Limosilactobacillus reuteri isolated from traditional sheep dry sausage evaluate its growth-promoting ability addition Arthrospira platensis or phycocyanin extract. In vitro...
Zearalenone (ZEA) is a toxic metabolite of the genus Fusarium, which causes hepatotoxicity and induces oxidative stress. Kefir an important probiotic dairy-product showing in vitro antioxidant potential. In this study, effect supplementation to mitigate ZEA toxicity rats was investigated. Animals were divided into four groups five each, received sterile milk (200 μL/day) during first week. Then, they switched μL/day), (40 mg/kg b. w./day) + for second Hematological biochemical parameters, as...
