Chemometric Tools

The emergence of multidrug-resistant bacteria has prompted the development of alternative therapies, including the use of natural products with antibacterial properties. The antibacterial properties of Zantaz honey produced in the Moroccan Atlas Mountains against Escherichia coli, Pseudomonas aeruginosa, and Staphylococcus aureus was evaluated and analyzed using chemometric tools. Minimum inhibitory concentration (MIC) and Minimum bactericidal concentration (MBC) against S. aureus were the lowest (112.5 ± 54.5 mg/mL), revealing that this species was most sensitive to Zantaz honey. P. aeruginosa showed an intermediate sensitivity (MIC= 118.75 ± 51.9 mg/mL), while E. coli was the most resistant to treatment (MIC = 175 ± 61.2 mg/mL). Content of monosaccharides, certain minerals, and phenolic compounds correlated with antibacterial activity (p < 0.05). Principal component analysis of physicochemical characteristics and antibacterial activity indicated that the parameters most associated with antibacterial activity were color, acidity, and content of melanoidins, fructose, epicatechin, methyl syringate, 4-coumaric acid, and 3-coumaric acid.

We assessed the genetic variation of 47 Moroccan populations of the North African water frog (Pelophylax saharicus) using partial sequences of the mitochondrial cytochrome oxidase subunit I gene (COI). All 239 samples belonged to the main haplotype clade previously identified from Morocco, with no haplotypes of the Algerian/Tunisian clades among our samples. Altogether 40 haplotypes were found, with a maximum of 13 mutational steps between them. Two weakly divergent haplogroups separated by a minimum of six mutational steps were distributed (i) in the Anti-Atlas and the Sahara (south of the High Atlas Mountains) versus (ii) in the Middle Atlas, the High Atlas, and in the Rif area north of the Atlas Massif. Haplotypes of the northern haplogroup were found at the southernmost locality, which might be due to human translocation, and co-occurrence of the two haplogroups was recorded at three sites within the range of the northern haplogroup.

Abstract The Atlas mountains of Tunisia have undergone a long and slow evolution. East-west trending structures were developed during Mesozoic deformation. Tertiary (pre-Burdigalian) movements heralded the major Plio-Pleistocene diastrophism, which continued until the end of the Pleistocene and produced folds with northeast-southwest trending axes. In recent Quaternary times, isostatic readjustment has produced depressions, both parallel and at right angles, which are superposed on the old fractures of the basement complex.
