Prevalence of Salmonella typhi and paratyphi infection in children: a hospital based study

The purpose of this study was to find out the prevalence and antibiotic sensitivity pattern of Salmonella typhi and paratyphi isolated from children presenting with fever at Kanti Children's Hospital in Kathmandu, Nepal. A total of 9,856 blood samples collected for culture during one year period (April 2007 to March 2008) were included in the study. Out of total, 235 (2.0%) were positive for S. typhi and paratyphi A. Of the total positive, 195 (83.0%) were S. typhi and 40 (17.0%) were S. paratyphi A. The growth positive rate in two genders (M: 53.2% and F: 46.8%) was not significant (P > 0.05). Over two-third of cases were clustered in the age-group of 1-10 years. The occurrence of infections was common in summer months (rainy season). S. typhi was found to be most sensitive to cefotaxime (100.0%) followed by ceftriaxone (98.9%), ofloxacin (93.5%), cotrimoxazole (93.5%) and chloramphenicol (93.2%) and was least sensitive to amoxyccilin (66.7%) followed by ciprofloxacin (86.6%). S. paratyphi also was found to be most sensitive to cefotaxime (100.0%), followed by ceftriaxone (97.4%), cotrimoxazole (97.1%) and chloramphenicol (92.5%) and was least sensitive to amoxycillin (15.0%) followed by ciprofloxacin (51.3%) and ofloxacin (70.3%).

Causative agents of urinary tract infections in children and their antibiotic sensitivity pattern: a hospital based study

A retrospective study was conducted to find out the causative agents of urinary tract infection (UTI) in children and their antibiotic sensitivity pattern among Nepalese children. This was done at Kanti Children's Hospital in Kathmandu (Nepal) by analyzing the records of urine samples collected for culture and sensitivity tests over a period of six months (April to November, 2007). Of the total 1878 mid-stream urine samples collected from suspected cases of UTI, 538 (28.6%) were positive for pathogenic organisms. There was no significant difference in growth positive rate in two genders (M: 51.7% and F: 48.3%). Of the various pathogenic organisms isolated, Escherichia coli constituted for 93.3% followed by Proteus sp, Klebsiella sp, Citrobacter sp, Staphylococcus aureus and others. E. coli was found to be most sensitive to amikacin, chloramphenicol, nitrofurantoin and ofloxacin and least sensitive to most commonly used drugs like cephalexin, nalidixic acid, cotrimoxazole and norfloxacin.

Bacteriological Profile of Neonatal Sepsis: A Hospital Based Study

Introduction: Neonatal sepsis is a major cause of mortality and morbidity in newborn. There are many factors that contribute to neonatal sepsis. The organisms responsible for early onset and late onset sepsis are different. Objective: This study was conducted to analyze the organisms responsible for early onset and late onset neonatal sepsis. Materials and Methods: A prospective hospital based study over the period of one year was conducted at neonatal intermediate care unit of Kanti Children's Hospital, Maharajgunj, Kathmandu, Nepal. Results: Organisms were isolated in 6.1% of the collected blood samples. The male female ratio of culture proven sepsis was 1.9:1. Escherichia coli were found to be the most common organism in both early onset and late onset sepsis. Staphylococcus aureus was more common in late onset sepsis than early onset sepsis.Conclusion: Escherichia coli were the most common organism in both early onset and late onset sepsis. Staphylococcal aureus was significantly more common in late onset sepsis than early onset sepsis.
