WebESBLs belong to the TEM, SHV, and CTX-M classes [11]. TEM BLs have amino acid substitutions around the active site of the enzyme that change the configuration to allow hydrolysis of oxymino-beta-lactam substrates [11]. Based on the type of change, hundreds of TEM-type enzymes have been described to date [12]. SHV-type ESBLs also WebObjective: This study was conducted to study ESBL production and occurrence of TEM, SHV and CTX-M beta lactamases in clinical isolates of Proteus species in a tertiary care …
