Characterization of the chromosomal cephalosporinases produced by Acinetobacter lwoffii and Acinetobacter baumannii clinical isolates.

TL;DR: Analysis of the interaction with 6-beta-iodopenicillanic acid allowed us to better discriminate the three beta-lactamases analyzed in the present study, which can be included in the group 1 functional class (5).

TEM-72, a New Extended-Spectrum β-Lactamase Detected in Proteus mirabilis and Morganella morganii in Italy
Mariagrazia Perilli,Bernardetta Segatore,M R de Massis,M L Riccio,Ciro Bianchi,A Zollo,G. M. Rossolini,Gianfranco Amicosante +7 more
TL;DR: Kinetic analysis showed that TEM-72 exhibits an extended-spectrum activity, including activity against oxyimino-cephalosporins and aztreonam, and Expression ofblaT EM-72 in Escherichia coli was capable of decreasing the host susceptibility to the above drugs.

Characterization of a new TEM-derived beta-lactamase produced in a Serratia marcescens strain.
Mariagrazia Perilli,Antonio Felici,Nicola Franceschini,A De Santis,L Pagani,F Luzzaro,Arduino Oratore,G. M. Rossolini,J R Knox,Gianfranco Amicosante +9 more
TL;DR: A natural TEM variant beta-lactamase was isolated from an epidemic strain of Serratia marcescens and revealed multiple point mutations located in the 42-to-44 tripeptide and positions 145 to 146, 178, and 238.

Characterization of a New Extended-Spectrum β-Lactamase (TEM-87) Isolated in Proteus mirabilis during an Italian Survey
Mariagrazia Perilli,Bernardetta Segatore,Maria Rosaria De Massis,Nicola Franceschini,Ciro Bianchi,G. M. Rossolini,Gianfranco Amicosante +6 more
TL;DR: Kinetic analysis of TEM-87 revealed extended-spectrum activity against oxyimino cephalosporins (preferentially ceftazidime) and aztreonam and Expression of blaTEM- 87 in Escherichia coli decreased the host susceptibility to these drugs.

Sensitivity of Aeromonas hydrophila carbapenemase to delta3-cephems: comparative study with other metallo-beta-lactamases.
Antonio Felici,Mariagrazia Perilli,Nicola Franceschini,G. M. Rossolini,Moreno Galleni,Jean-Marie Frère,Arduino Oratore,Gianfranco Amicosante +7 more
TL;DR: Ceftriaxone and ceftriAXone S-oxide behaved as inactivators against the metallo-beta-lactamase of Aeromonas hydrophila AE036 and as substrates for the zinc beta-lactoramase produced by Bacillus cereus and Stenotrophomonas maltophilia ULA 511.
