Studio sulla relazione tra la resistenza alla kanamicina ed il gene “Putative aminoglycoside 3’-phosphotranferase (PAPH) in Sinorhizobium meliloti ce…
2008
Il ceppo selvatico di Sinorhizobium meliloti 1021 è sensibile alla kanamicina (30 mg/l) anche se Capela et al. (Proc. Natl. Acad. Sci. U.S.A.(2001), 98: 9877-9882), analizzando l’intero genoma, hanno trovato un gene codificante per una “putative aminoglycoside 3'-phosphotransferase” (PAPH), coinvolta nella resistenza ad antibiotici aminoglicosidici quali la kanamicina. Un mutante spontaneo (GM42) kanamicina resistente (200 mg/l) di Sinorhizobium meliloti 1021 è stato caratterizzato da un punto di vista molecolare e fenotipico per analizzare l’attività del gene PAPH. Il ceppo parentale e GM42 sono stati caratterizzati da un punto di vista microbiologico tramite il MicroLog System Biolog. I r…
Food-additive-induced urticaria: a survey of 838 patients with recurrent chronic idiopathic urticaria
2005
<i>Background:</i> Recurrent chronic idiopathic urticaria (RCIU) is a common skin condition that affects 0.1–3% of the population in the USA and Europe and accounts for nearly 75% of all ‘ordinary’ chronic urticaria (CU) cases. <i>Methods:</i> We studied 838 consecutive patients with RCIU referred to hospital between 1998 and 2003. Patients with known causes of CU were excluded. Clinical history, physical examination, and symptom diaries were evaluated during two periods, a diet-free period (1 week) and a food-additive-free diet (FAFD) period (4 weeks), respectively, and two double-blind placebo-controlled (DBPC) challenges of six food additives were administered. Th…
