| [incidence of extended spectrum beta-lactamase (esbl)-producing enterobacteria in the area of caltagirone (sicily)]. | the authors report the incidence of extended spectrum b-lactamases (esbl)- producing strains in 1,602 enterobacteria consecutively isolated, from april 2002 to december 2003, in caltagirone (ct) hospital, and their in vitro susceptibility to several antimicrobial agents. the incidence of esbl-producing enterobacteria was equal to 1.5%, mainly among escherichia coli, klebsiella spp and citrobacter koseri, isolated by emergency and medicine wards. in vitro, the enterobacteria were fully susceptibl ... | 2004 | 15316296 |
| molecular epidemiological survey of citrobacter freundii misidentified as cronobacter spp. (enterobacter sakazakii) and enterobacter hormaechei isolated from powdered infant milk formula. | a total of 75 powdered infant milk formula (pif) samples collected from pharmacies and drugstores in western sicily, italy, and representative of 12 different brands were analyzed in this study to evaluate their microbiological quality. according to the u.s. food and drug administration protocol, 32 samples out of 75 were contaminated by enterobacteria. commercial biochemical api(r) 20e-system identification method indicated that six pif samples were presumptively contaminated by cronobacter spp ... | 2011 | 21204699 |
