Agronomic advantage of bacterial biological nitrogen fixation on wheat plant growth under contrasting nitrogen and phosphorus regimes.

Introduction: Given their remarkable capacity to convert atmospheric nitrogen into plant-accessible ammonia, nitrogen-fixing microbial species hold promise as a sustainable alternative to chemical nitrogen fertilizers, particularly in economically significant crops like wheat. This study aimed to identify strains with optimal attributes for promoting wheat growth sustainably, with a primary emphasis on reducing reliance on chemical nitrogen fertilizers.

Methods: We isolated free nitrogen-fixing strains from diverse rhizospheric soils across Morocco.

SARS-CoV-2-Neutralizing Antibody Response and Correlation of Two Serological Assays with Microneutralization.

SARS-CoV-2 has caused a huge pandemic affecting millions of people and resulting innumerous deaths. A better understanding of the correlation between binding antibodies and neutralizing antibodies is necessary to address protective immunity post-infection or vaccination. Here, we investigate the humoral immune response and the seroprevalence of neutralizing antibodies following vaccination with adenovirus-based vector in 177 serum samples.

Draft Genome Sequence of Escherichia coli DBS1, Isolated from a Patient with Urinary Tract Infections in Morocco.

Here, we present the draft genome assembly of Escherichia coli DBS1, which was originally isolated from a urine sample from a male patient with urinary tract infections in Rabat, Morocco.

Eco-friendly degradation of reactive red 195, reactive blue 214, and reactive yellow 145 by Klebsiella pneumoniae MW815592 isolated from textile waste.

The water is used in many textile manufacturing steps beyond cleaning. The quantity and the significant chemical load of the effluents generated constitute the primary challenge of the textile industry. In order to discover new sustainable methods to overcome this problem, the aim of this research was to study the potential for degradation of Reactive Blue 214, Reactive Red 195, and Reactive Yellow 145 using a dye degrading bacterium.

and : Two Actinomycetes Families from Moroccan Oat Soils Enhancing Solubilization of Natural Phosphate.

Soil actinomycetes explorations appear to be an efficient alternative as biofertilizers to optimize the use of phosphorus (P) resources and enhance plant growth. This research aimed to explore the distribution of actinomycetes isolated from four different rhizospheric Moroccan oat soils and to investigate their potential for P solubilization. The distribution of actinomycetes was significantly more abundant in Settat (9.

Multiple Potential Plant Growth Promotion Activities of Endemic spp. from Moroccan Sugar Beet Fields with Their Inhibitory Activities against spp.

The characterized 10 isolates were previously selected by their abilities to solubilize phosphates. To investigate whether these isolates represent multifaceted plant growth-promoting rhizobacteria (PGPR), their potassium-solubilizing, auxin-producing and inhibitory activities were determined. The 10 spp.

Isolation and Characterization of Phosphate Solubilizing sp. Endemic from Sugar Beet Fields of the Beni-Mellal Region in Morocco.

In the course of our research, aimed at improving sugar beets phosphorus nutrition, we isolated and characterized sp. strains, endemic from sugar beet fields of the Beni-Mellal region, which are able to use natural rock phosphate (RP) and tricalcium phosphate (TCP) as sole phosphate sources. Ten sp.

Complete Genome Sequence of a 2019 Novel Coronavirus (SARS-CoV-2) Strain Causing a COVID-19 Case in Morocco.

Here, we report a complete genome sequence obtained for a novel severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) strain isolated from a nasopharyngeal swab specimen of a Moroccan patient with coronavirus disease 2019 (COVID-19).

Single-Molecule Sequencing (PacBio) of the NRCS-A Clone Reveals the Basis of Multidrug Resistance and Adaptation to the Neonatal Intensive Care Unit Environment.

The multi-resistant clone NRCS-A has recently been described as a major pathogen causing nosocomial, late-onset sepsis (LOS) in preterm neonates worldwide. NRCS-A representatives exhibit an atypical antibiotic resistance profile. Here, the complete closed genome (chromosomal and plasmid sequences) of NRCS-A prototype strain CR01 and the draft genomes of three other clinical NRCS-A strains from Australia, Belgium and the United Kingdom are annotated and compared to available non-NRCS-A genomes.

Genome Sequences of Multiresistant Staphylococcus capitis Pulsotype NRCS-A and Methicillin-Susceptible S. capitis Pulsotype NRCS-C.

Here, we report the draft genome sequences of methicillin-susceptible Staphylococcus captis pulsotype NCRS-C (CR02 strain) and multiresistant Staphylococcus captis pulsotype NCRS-A (CR07 strain).

Genome Sequences of Four Staphylococcus capitis NRCS-A Isolates from Geographically Distant Neonatal Intensive Care Units.

Staphylococcus capitis pulsotype NRCS-A was previously reported as a frequent cause of late-onset sepsis in neonatal intensive care units (NICUs) worldwide. Here, we report the whole-genome shotgun sequences of four S. capitis pulsotype NCRS-A strains, CR03, CR04, CR05, and CR09, isolated from Belgium, Australia, the United Kingdom, and France, respectively.

Non-contiguous finished genome sequence of Staphylococcus capitis CR01 (pulsetype NRCS-A).

Staphylococcus capitis is a coagulase-negative staphylococcus (CoNS) commonly found in the human microflora. Recently, a clonal population of Staphylococcus capitis (denominated NRCS-A) was found to be a major cause of late-onset sepsis (LOS) in several neonatal intensive care units in France. Here, we report the complete genome sequence and annotation of the prototype Staphylococcus capitis NCRS-A strain CR01.

Characterization of a novel composite staphylococcal cassette chromosome mec (SCCmec-SCCcad/ars/cop) in the neonatal sepsis-associated Staphylococcus capitis pulsotype NRCS-A.

Multiresistant Staphylococcus capitis pulsotype NRCS-A has been reported to be a major pathogen causing nosocomial bacteremia in preterm infants. We report that the NRCS-A strain CR01 harbors a novel 60.9-kb composite staphylococcal cassette chromosome mec (SCCmec) element, composed of an SCCmec with strong homologies to Staphylococcus aureus ST398 SCCmec and of an SCCcad/ars/cop harboring resistance genes for cadmium, arsenic, and copper.

Antifungal effects of aminosulphoxide and disulphide derivatives.

2-Benzenesulphinyl-(1,4)-naphtoquinone and 14 derivatives were synthesised and were used to evaluate their cytotoxicity against a human myelomonocyte cell line and their antifungal activity against two yeast, i.e. Candida albicans and C.

Streptomyces ferralitis sp. nov., a novel streptomycete isolated from a New-Caledonian ultramafic soil.

The taxonomic position of an actinomycete isolated from an ultramafic soil in New Caledonia was determined using a polyphasic approach. The isolate, which was designated SFOp68(T), was shown to have chemical and morphological properties typical of streptomycetes. An almost complete 16S rRNA gene sequence of the isolate was generated and compared with sequences of representative streptomycetes.

Screening of nonpolyenic antifungal metabolites produced by clinical isolates of actinomycetes.

The purpose of this work was to screen clinical isolates of actinomycetes producing nonpolyenic antifungals. This choice was made to limit the problem of rediscovery of well-known antifungal families, especially polyenic antifungals. One hundred and ten strains were tested, using two diffusion methods and two test media, against three yeast species and three filamentous fungi.
