This work represents the first initiative to analyze distribution of B. thuringiensis in Algeria and evaluate biological potential isolates. A total 157 isolates were recovered, with at least one isolate 94.4% samples. The highest Bt index was found samples from rhizospheric soil (0.48) Mediterranean area (0.44). Most showed antifungal activity (98.5%), contrast few that had antibacterial (29.9%). high genetic diversity made evident by finding many different crystal shapes various...
This study aimed to screen and characterize colistin-resistant strains isolated from different livestock species in Algeria, including sheep, goats, dromedaries.
In this study, we identified a new Bacillus strain isolated from an Algerian salty lake that produces metabolites are active against Gram-positive and Gram-negative bacteria, as well fungal pathogens. The draft genome sequence of the is presented herein. Genome analysis to be B. amyloliquefaciens subspecies plantarum F11, showed carries gene clusters for production number bioactive surface-active compounds. These include lipopeptides surfactin fengycin, antibacterial polyketides macrolactin...
Bacillus thuringiensis is widely used as a bioinsecticide due to its ability form parasporal crystals containing proteinaceous toxins. It member of the cereus sensu lato, group with low genetic diversity but produces several promising antimicrobial compounds. B. DNG9, isolated from an oil-contaminated slough in Algeria, has strong antibacterial, antifungal and biosurfactant properties. Here, we report 6.06 Mbp draft genome sequence DNG9. The encodes gene inventories for biosynthesis...
The current study aimed to screen Bacillus strains with wide-spectrum quorum quenching (QQ) activity against N-acyl-l-homoserine lactones (AHLs), helpful in controlling virulence traits Gram-negatives, including biofilm formation and also anti-biofilm Gram-positives.A total of 94 halotolerant isolated from soil salt-lake sediment samples Algeria were examined for the presence QQ AHLs, aiiA gene, encoding an AHL lactonase enzyme typical spp., antimicrobial activities Pseudomonas aeruginosa...
Opportunistic infections constitute a major challenge for modern medicine mainly because the involved bacteria are usually multiresistant to antibiotics. Most of these possess remarkable ability adapt various ecosystems, including those exposed anthropogenic activities. This study isolated and identified 21 opportunistic from two polluted rivers, located in Algiers. Cadmium, lead, copper concentrations were determined both water samples evaluate heavy metal pollution. High prevalence...
ABSTRACT Two strains of Bacillus , B. cereus E41 and anthracis F34, were isolated from a salt lake in Aïn M’lila-Oum El Bouaghi, eastern Algeria, Ain Baida-Ouargla, southern respectively. Their genomes display genes for the production several bioactive secondary metabolites, including polyhydroxyalkanoate, iron siderophores, lipopeptides, bacteriocins.
Vancomycin-resistant enterococci (VRE) are a public health concern as they lead to therapeutic impasses and play pivotal role in the dissemination of vancomycin resistance genes. As recent evidence suggests that wildlife can bacterial resistomes, this study explored potential Algerian wild birds reservoir VRE. A total 222 cloacal fecal samples were collected from various bird species screened for VRE using selective medium. Of 47 isolated strains, 22 identified Enterococcus casseliflavus...
Freshwater fish are often exposed to threats from anthropogenic or natural origins, such as pathogenic opportunistic microorganisms responsible for a broad range of severe infections. In this study, we aimed assess microbiological threat in an Algerian northwestern dam Sekkak (Tlemcen) by evaluating the diversity ichtyopathogenic bacteria. order determine water quality, physicochemical analyses were carried out situ. Ichtyopathogenic bacteria isolated on selective media and identified API...
