Antibiotics susceptibility of E.cloacae and E.sakazakii that isolated from different clinical specimens

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.
