Mitochondrial 16S rDNA analysis of Tunisian androctonus species [scorpions, buthidae]: phylogenetic approach

Tunisian Androctonus species, for long time discussed, were recognized on the basis of mitochondrial 16S rDNA sequences. Although the analysed nucleotide sequence is rather short [about 300 bp], the obtained phlogenetic trees revealed that A. amoreuxi and A. aeneas form two well-supported sister clades against A. australis haplotypes. Each specimen of the very rare species A. aeneas showed a specific haplotype, but together formed a well-defined clade. Some A. amoreuxi specimens highlighted unidirectional mitochondrial introgression from neighbouring A. australis population. Within A. australis, previously described, subspecies subdivision [A. a. hector and A. a. garzonii] was not supported

Les oesophagites a candida a propos de 9 observations

The authors report 9 cases of Candida esophagitis observed during a 2 years period. They outline the relative rarity of this entity in their practice and the high frequency of its association with a preexisting esophageal disease. Finally, they discuss the clinical features, the diagnostic methods and the treatment in view of the relevant literature
