Background: Bloodstream infection (BSI) is a signifi cant cause of morbidity and mortality. In Nepal, very few studies on BSIs have restricted the understanding of their cause, prevention and treatment. This cross-sectional study was conducted to isolate BSIs causing pathogens and determine their antibiotic susceptibility pattern in patients visiting Kathmandu ModelHospital during December 2012 to May 2013.Materials and Methods: Standard laboratory procedure was used to screen, isolate and identify the bacteria from 1,205 patients. The antibiotic susceptibility pattern (AST) was analyzed by modifi ed Kirby Bauer technique and data were analyzed using SPSS version-16.Results: Out of 1,205 blood samples, 186 (15.4 %) were culture positive. The most common bacteria isolated were: Salmonella spp., Escherichiacoli, Klebsiella pneumoniae and CoNS. Gram-negative bacteria were the predominant causes of BSIs. Salmonella Typhi was isolated in 71 % cases of bloodstream infection followed by Salmonella Paratyphi A in 16 %, Escherichia coli in 5.3 % and Klebsiella pneumonia in 0.5 %. The gram-positive organism responsible for causing BSI was coagulase-negative staphylococcus in 7 % cases. There was no significant association between bacteremia and gender of the patients. During ASTs, Gram-negative bacteria were sensitive to Chloramphenicol with only 0.5 % resistivity. Salmonella Typhi (85.6 % of isolates) showed resistance to Nalidixic acid. Gram-positive bacteria showed 100 % sensitivity towards Chloramphenicol and Gentamicin and were least sensitive to Amoxicillin.Conclusion: Salmonella spp., was major cause of BSIs. Increase in antibiotic resistivity for BSI causing pathogens has necessitated continuous monitoring of the susceptibility of organisms towards antibiotics.Asian Journal of Medical Sciences Vol.7(2) 2015 71-75

Background: Enteric fever is one of the most common systemic infections of developing countries like Nepal. The changing trend of antibiotic susceptibility and increasing rate of resistance to the commonly used antibiotics has been of great concern in the proper treatment and prevention of this disease. This study aims to investigate the current antibiotic susceptibility pattern of Salmonella typhi and paratyphi A and B. Materials and Methods: This study was carried out at Patan hospital of Lalitpur, Nepal from ____ to -------. Blood culture sample were collected from suspected patients presenting to different departments of the hospital and tested microbiologically by standard procedure. Antibiotic susceptibility test was performed by Kirby Bauer Disc Diffusion method and results were interpreted by National Committee for Clinical Laboratory (NCCLS) guidelines. Results: Out of the total sample of 212, 40(18.8%) cases were isolated as Salmonella species. Out of these, 29(72.5%) cases were S typhi and 11(27.5%) were S paratyphi. Isolates were mainly from adult age group. Regarding the antibiotic susceptibility pattern, the sensitivity to chloramphenicol was 95% and to cotrimoxazole 97% whereas the sensitivity to ciprofloxacin was 52.5% and 27.5% for Ofloxacin. Nalidixic Acid Resistance Salmonella typhi strain was 60.0 percent. Sensitivity to ceftriaxone, meropenem and colistin was found to be 100 percent. Conclusions: A high degree of variability is seen in antimicrobial sensitivity pattern with very high degree of sensitivity to the historically used antibiotics like chloramphenicol and cotrimoxazole. Unfortunately, sensitivity to quinolones was seen to be very low, which were used widely in the last two decades.

Objectives: This study was aimed to know the prevalence of Nalidixic acid resistant Salmonella isolates and their antibiotic susceptibility pattern.Methods: A total of 4619 febrile patients suspecting the cases of typhoid fever by clinician, attending at Shree Birendra hospital during May- November 2013 were subjected to culture. Blood sample (5ml) was collected from the suspected cases and inoculated immediately into 45ml of Brain heart infusion broth (BHI) and further processed for the identification of Salmonella Typhi and S. Paratyphi. Antimicrobial susceptibility pattern of S. Typhi and S. Paratyphi isolates were determined by the modified Kirby-Bauer disc diffusion method.Results: Out of 4619 blood sample, 8.7% (n= 403) sample were culture positive. Among culture positive, 66.3%(n=267) cases were S. Typhi, 26.1% (n=105) cases were S. Paratyphi and 7.7% (n=31) were other than Salmonella isolates respectively. Out of 372 Salmonella isolates, most of the S. Typhi isolates i.e. 95.51%(n=255) and S. Paratyphi isolates i.e. 97.14%(n=102) are highly resistant to nalidixic acid. Most of these isolates were also found resistant to ciprofloxacin and ofloxacin.Conclusion: Therefore, screening of nalidixic acid susceptibility might be done prior to prescribe the drug for the treatment of enteric fever.

Background: Methicillin resistant Staphylococcus aureushas emerged as one of the most important nosocomial pathogens. It invokes a tremendous financial burden and enhanced morbidity and mortality due to difficult to treat systemic infections.Aim of this study was to determine antibiotic susceptibility pattern of Staphylococcus aureus and Methicillin resistant Staphylococcus aureus. Materials and Methods: Different clinical specimens were collected and processed for routine culture and antibiotic sensitivity test by standard microbiology techniques. Results: Out of 1173 samples received for microbiological examination, 100 were found to be S. aureus with 19% cases were Methicillin resistant Staphylococcus aureus (MRSA). Fourteen MRSA were found from inpatient and 5 were from outpatient. MRSA was found higher in female than male and maximum number (31.5%) was found in age group 0-10 years. Staphylococcus aureus was 100% sensitive to Vancomycin followed by Amikacin (90%), Gentamycin (83%), and tetracycline (81%). On urine isolates Nitrofurantoin(91.6%) was drug of choice. All the isolates were resistant to Penicillin G. In case of Methicillin resistant Staphylococcus aureus showed 100% sensitive to Vancomycin followed by Amikacin (84.2%), Tetracycline (63.1%), Ciprofloxacin (42%) and Gentamycin (36.8%). Among urine isolates Nitrofutantoin showed 87.5% sensitive followed by Norfloxacin (75%). Conclusion: Methicillin resistant Staphylococcus aureus was found 19% of Staphylococcus aureus isolates. It was most common in females, hospitalized patients and young age group. Vancomycin seems to be drug of choice followed by Amikacin. It would be helpful to formulating and monitoring the antibiotic policy and ensure proper empiric treatment.
