[A rapid method of grouping beta-hemolytic streptococci using extemporaneous coagglutination].

Extemporaneous coagglutination procedure for the serological grouping of beta-hemolytic streptococci is reported. Streptococcal group antigens were extracted with nitrous acid. 250 strains of groups A, B, C, F and G streptococci were tested with this method. An agreement of 100% was found between this method and the Lancefield capillary precipitation procedure. Extemporaneous coagglutination method was found to be rapid, reliable, easy and economical and could be adopted in any routine diagnostic laboratory.

[Extraction of chromosomal DNA from Staphylococcus and Listeria by a rapid method using achromopeptidase].

A rapid and simple method for preparation of chromosomal DNA from Gram-positive bacteria is reported. Susceptibility to lysis with Sodium Dodecyl Sulfate (SDS) increases when undergoing treatment with acetone before being digested by bacteriolytic enzymes. Rapid lysis of Staphylococcus and Listeria cells is obtained through a respective treatment by lysozyme with lysostaphine and by lysozyme with achromopeptidase, adding to that the effect of SDS in Tris-Hcl buffer. This procedure of preparing chromosomal DNA provides 1 to 4 mg of DNA out of 1 g of bacterial cells in a day.

[Cavitary tumor lesions of the small intestine. Radio-ultrasonic diagnosis. Apropos of 4 cases].

Excavated lesions of small intestine are rare and generally of a malignant nature, the must frequent cause being metastases. In Tunisia these lesions are usually the aneurysmal type of lymphoma. The etiology in a series of four cases of excavated lesion of small intestine was not always lymphomatous. Radiologic and ultrasound semeiology are outlined and etiologies discussed. Scan images are not available since whole-body scanners are not in use in Tunisia.

[7th epidemic of cholera in Maghreb. Epidemiologic data compared].

[Adrenal tumors in Beckwith-Wiedemann syndrome. Apropos of a case].

A case of a neonate with Beckwith-Wiedemann syndrome is presented. Antenatal sonography detected a right adrenal cystic mass confirmed in post-natal which resolved spontaneously within 1 month. The child developed an adrenal adenoma detected by abdominal sonography at six months of surveillance. The authors review the different adrenal lesions possibly associated with Beckwith-Wiedemann syndrome and specially the pseudo-tumorous lesions. The value of abdominal sonography in the neonatal periods and in the surveillance of children with Beckwith-Wiedemann syndrome is emphasized.
