Abstract :
Two species of Enterobacter (84 isolates) E.cloacae (75 isolates) and E.sakazakii (9 isolates) were isolated from different clinical specimens . They are observed , all isolates (84) were resistant to β– lactam antibiotics (amoxicillin and cefoxitin) but the resistance for cephalothin ,cephalexin and ampicillin , were 98% , 92% and 90% respectively , 75% , 61% and 50% for doxycycline , nitrofurantion and chloramphenicol respectively .The high values of MICs were registered to cefoxitin (46-256) µg / ml , while the lower MICs values of cefepime , imipenem and ciprofloxacin were (0.5 -32 , 0.5 -16 , 0.5 – 4) µg / ml respectively . From the study 72 (86%) of isolates were produced β– lactamase , 63 isolates (84%) of E.cloacae can produce β –lactamase , and all isolates (9)of E.sakazakii gave positive result for β –lactamase.
