Comparison of antibiotic resistance of bacterial agents associated in septicaemia in children and infants

Septicaemia is a leading cause of morbidity and mortality of infant’s and childerens espicially in first week of their life، both in developed and underdeveloped countries. The aim of this research was to study of bacterial agents causing septicaemia and to determine their antibiotic suseptibility patternes. This was a descriptive study، it was performed during eight months from October 2011 till May 2011. In total 216 blood culture samples of children suspected of septicaemia in children health centre hospital were send to the laboratory for investigation. The bacterial identification was carried out by culturing and conventional biomedical tests. The antibiotic sensitivity tests were performed by disk diffusion method. These data are analyzed by SPSS and the results Expressed as relative frequencies. Out of 216 tested samples 55 (25. 6%) were positive and 161 (74. 54%) negative. The dominated bacteria was Escherichia coli (31. 42%)، followed by Staphylococcus aureus (22. 86 %)، Klebsiella pneumonia (20%))، Staphylococcus epidermidis (14. 28%)، Streptococcus pneumonia (2. 86%)، Salmonella typhi (2. 86%)، Enterobacter cloacae (2. 86%) and Stenotrophomonas maltophilia (2. 86%). In general gram-negative bacteria were isolated more than gram-positive. Staphylococcus bacteria were more resistant to antibiotics than other isolated bacteria، and were 100% resistant to penicillin. The enterobacteriaceae were more sensitive to norfloxacin، amikacin، tobramycin، and they were 100% resistant to ampicillin. The results obtained in this study showed that gram-negative bacteria are more responsible in septicaemia in children ward، and norfloxacin is the more effective antibiotic in comparison with others.
