Carvacrol and Thymol Enhance the Quality of Beni Arouss Buck Semen Stored at 4 °C Thanks to Their Antimicrobial Properties.

This study aims to investigate the impact of carvacrol and thymol on the quality of Beni Arouss buck semen stored in skim milk at 4 °C. Ejaculates were collected from eight Beni Arouss bucks weekly for 11 weeks, pooled, and then divided into three equal parts. Samples were diluted to 400 × 10 sperm/mL in skim milk (control) and skim milk supplemented with a single dose of 200 µM carvacrol and thymol each.

Quality of life assessment of breast cancer survivors in Northern Morocco: Rural-urban disparity.

This article is a cross-sectional study of 216 women undergoing adjuvant hormone therapy for breast cancer in two oncology centers in northern Morocco. Quality of life (QoL) was assessed using the Functional Assessment of Cancer Therapy (FACT) questionnaire and its endocrine subscale (ES). The relationship between rural-urban status in our sample and QoL was assessed by linear regression analysis using sociodemographic and clinical variables as covariates.

Gamma irradiation-induced genetic variability and its effects on the phenotypic and agronomic traits of groundnut (L).

In order to increase genetic variability for the improvement of groundnut, two varieties, namely Kp29 and Fleur11, were treated with six different gamma irradiation doses. A significant effect of mutagenesis was distinctly observed in the stem lengths, roots, and survival percentage in both varieties. The radio-sensitivity test showed a mean lethal dose of 436.

Effects of Origanum majorana essential oil and antibiotics on the quality of frozen thawed Beni Arouss buck semen.

This study aims to investigate the effects of Origanum majorana (OM) essential oil (EO) at different concentrations and antibiotics on post-thawed Beni Arouss buck semen quality. Semen collection was performed using artificial vagina from eight Beni Arouss bucks. Ejaculates were pooled, divided into 12 equal aliquots, washed and diluted to 400 × 10 sperm/ml (with 7% of glycerol).

Genetic diversity of rhizobia isolated from nodules of Trigonella foenum-graecum L. (fenugreek) cultivated in Northwestern Morocco.

The present work aimed to characterize rhizobia nodulating Trigonella foenum-graecum L. (fenugreek) cultivated in six different geographical locations in Northwestern Morocco. Forty-seven rhizobial isolates from nodules of Trigonella foenum-graecum were grouped into thirteen clusters using the Rep-PCR technique.

[Effectiveness of aqueous extracts of aromatic and medicinal plants against tomato grey mould in Morocco].

Grey mould is a major disease threatening the Moroccan tomato; this disease is often controlled by fungicides. However, the latter are a real danger to human health and environment. Thus, this study is part of the research of harmless alternatives such extracts of aromatic and medicinal plants (Lavandula officinalis, Thymus vulgaris, Cymbopogon citratus, and Melissa officinalis).

Prevalence of PMQR genes in E. coli and Klebsiella spp. isolated from North-West of Morocco.

Objectives: Plasmid mediated quinolone resistance (PMQR) genes are increasingly detected worldwide. However, in Morocco a few studies have been carried out. The aim of this study was to investigate the prevalence of these determinants among Escherichia coli and Klebsiella spp.

Phenotypic and genetic characterization of rhizobia isolated from Hedysarum flexuosum in Northwest region of Morocco.

Seventy bacterial strains were isolated from root nodules of the legume Hedysarum flexuosum grown wild in soils from Northwest Morocco. Repetitive extragenic palindromic (REP)-polymerase chain reaction (PCR) clustered the strains into 30 REP-PCR groups. The nearly complete sequence of the 16S rRNA gene from a representative strain of each REP-PCR pattern showed that 17 strains were closely related to members of the genus Rhizobium of the family Rhizobiaceae of the Alphaproteobacteria.

Bradyrhizobium rifense sp. nov. isolated from effective nodules of Cytisus villosus grown in the Moroccan Rif.

Two bradyrhizobial strains, CTAW71(T) and CTAW69, previously isolated from root nodules of Cytisus villosus, have been analysed using a polyphasic approach. These strains have identical 16S rRNA genes and their closest relative species is Bradyrhizobium cytisi, whose type strain CTAW11(T) presented 99.8% identity with respect to strain CTAW71(T).

Characterization of Bradyrhizobium species isolated from root nodules of Cytisus villosus grown in Morocco.

From a total of 73 bacterial strains isolated from root nodules of Cytisus villosus grown in soils of the central-western region of the Moroccan Rif, 68 strains clustered into 19 repetitive extragenic palindromic (REP)-polymerase chain reaction (PCR) groups. The nearly complete 16S rRNA gene sequence from each strain showed they were closely related to members of the genus Bradyrhizobium of the Alphaproteobacteria, but affiliation at the species level was not clear. Sequencing of the housekeeping genes glnII and recA, and their concatenated phylogenetic analysis showed that 11 out of the 19 strains belong to Bradyrhizobium canariense and that another three strains were Bradyrhizobium japonicum.

Bradyrhizobium cytisi sp. nov., isolated from effective nodules of Cytisus villosus.

Several strains isolated from Cytisus villosus nodules have been characterized based on their diverse genetic, phenotypic and symbiotic characteristics. According to 16S rRNA gene sequence analysis, the isolates formed a group that was closely related to Bradyrhizobium canariense BTA-1(T) with 99.4% similarity.

Characterization of Salmonella Enteritidis isolated from foods and patients in northern Morocco.

Objectives: This study aimed to investigate Salmonella Enteritidis strains isolated from human and food sources in the north of Morocco by means of phenotypic and genotypic methods.

Methodology: Fifteen isolates from humans and food were submitted to phage typing, XbaI-macrorestriction (pulsed field gel electrophoresis [PFGE]), enterobacterial repetitive intergenic consensus (ERIC-PCR), antimicrobial susceptibility testing, and PCR assay targeting the spvR and invA genes.

Results: Six fingerprinting profiles were obtained with the ERIC-PCR method, four with PFGE profiling, five with antimicrobial resistance, three with phage typing, and only one with plasmid profiling.

Isolation, drug resistance and molecular characterization of Salmonella isolates in northern Morocco.

Objectives: The objective of this investigation was to assess the methods for the characterization of Salmonella isolates and to identify relationships of Salmonella isolates from human and food sources in northern Morocco.

Methodology: Several Salmonella serotypes were isolated from human and food samples and were characterized using conventional culture methods, biochemical, serological, antimicrobial testing, and phage typing. Molecular analyses such as enterobacterial repetitive intergenic consensus (ERIC)-PCR, macrorestriction profiling by pulsed-field gel electrophoresis (PFGE), and virulence gene analysis were also performed.

Phenotypic and genotypic characterizations of rhizobia isolated from root nodules of peanut (Arachis hypogaea L.) grown in Moroccan soils.

The phenotypic and genotypic characterization of sixty-two rhizobial isolates obtained from nodules of Arachis hypogaea in north-western Morocco was performed. Their physiological and biochemical properties revealed a great deal of diversity among them. Isolates were classified into two major groups based on the numerical analysis of their phenotypic and genotypic characteristics.
