Bacterial isolates from blood cultures of children with suspected septicaemia in Calabar, Nigeria

Abstract

BackgroundSepticaemia is a common cause of morbidity and mortality among children in the developing world. This pattern has changed little in the past decade. Physical signs and symptoms, though useful in identifying possible cases have limited specificity. Definitive diagnosis is by bacteriologic culture of blood samples to identify organisms and establish antibiotic susceptibility. These results are usually not available promptly. Therefore a knowledge of epidemiologic and antimicribial susceptibility pattern of common pathogens is useful for prompt treatment of patients. This report highlights the pattern of bacterial isolates in our environment from a retrospective study of our patients' records.MethodsOne thousand, two hundred and one blood samples were analysed from children aged 0–15 years, admitted into the children's wards of the University of Calabar Teaching Hospital, Calabar, Nigeria with features suggesting septicaemia. Samples were collected under aseptic conditions and cultured for aerobic and anaerobic organisms. Isolates were identified using bacteriologic and biochemical methods and antibiotic sensitivity determined by agar diffusion method using standard antibiotic discs.ResultsBacteria was isolated in 552 (48.9%) of samples with highest rates among newborns (271 : 50.8). The most frequent isolates were Staphylococcal aureus (48.7%) and Coliforms (23.4%). Results showed high susceptibilities to the Cephalosporins (Ceftriazone- 100%:83.2%, Cefuroxime-100%:76.5%) and Macrolides (Azithromycin-100%:92.9%) for S. aureus and coliforms respectively. This study underscores the importance of septicaemia as a common cause of febrile illness in children and provides information on common prevalent aetiologic agents and drug susceptibilities of the commonest pathogens.ConclusionStaphylococcus aureus and coliforms were the leading causes of septicaemia in children in this locality, and the third generation cephalosporins and azithromycin were shown to be effective against these pathogens.

Microbial Profile of Neonatal septicaemia in a tertiary care hospital of Bhopal

“…This observation is in accordance with the study conducted by Karki et al 6 in Nepal, Karthikeyan et al 13 in India, Meremikwu et al 14 in Nigeria and Aziz et al 15 in Pakistan.…”

Prevalence and Antibiotic Resistance of Neonatal Sepsis Pathogens in Neyshabour, Iran

“…While in some studies it has been reported as high as 44.7% (Ethiopia) (12) and 45.9% (Nigeria) (13), in other studies it is about 20% (14). It was 11.9% in this study, which can be explained by the different clinical criteria for suspicion of sepsis and taking blood samples, the technique of culture (traditional culture vs. BACTEC), quality of life and measures of health care and hospital services in various countries (15,16).…”

Evaluation of hypoglycemic status and causative factors in neonatal sepsis

“…The isolation rate of bacteria in this study is comparable to rates reported in Nigeria (45.9%), India (52.6%), Pakistan (54.0%) and Uganda (37.5%). 34,33,39,40 Lower isolation rates were reported in Ethiopia (23.1%-27.9%) and studies conducted in other developing countries e.g. in Iran (6.6%) (28), Bahrain (4.2%).…”

“…28 Clinical assessment by using signs and symptoms is a useful guide to provisional diagnosis of neonatal sepsis. 34 Reports from India showed that 50-60% of septic babies were premature neonates and verylow-birth-weight (VLBW) were more vulnerable. In our cases, 48.0% were low-birth-weight (LBW) babies and 20.8% were premature neonates.…”
