Insights
Escherichia coli (E.coli) and Shigella were the most common bacterial causes of infectious diarrhea in children in Iran. Ceftizoxime is effective against Shigella, but Cefixime is not recommended.
Area of Science:
- Pediatrics
- Infectious Diseases
- Microbiology
Background:
- Infectious diarrhea is a significant global cause of child mortality and morbidity.
- Identifying common bacterial pathogens and their antibiotic resistance is crucial for effective treatment.
Purpose of the Study:
- To identify prevalent bacteria causing diarrhea in children.
- To determine the antimicrobial susceptibility patterns of these bacteria.
Main Methods:
- Bacterial culture and isolation from fecal specimens of children under 14 with acute diarrhea.
- Antimicrobial susceptibility testing using disk diffusion and micro dilution methods.
Main Results:
- Bacteria were isolated in 27.9% of 172 pediatric patients.
- E.coli and Shigella were the most frequently identified pathogens.
- Shigella isolates were susceptible to Ceftizoxime and ciprofloxacin but resistant to Cefixime.
Conclusions:
- E.coli is the leading bacterial cause of childhood diarrhea in the studied region.
- Ceftizoxime is a suitable antibiotic for treating childhood shigellosis, while Cefixime is not recommended.
Background:
Infectious diarrhea is one of common cause of children diarrhea causing mortality and morbidity worldwide. This study was performed to identify the common bacteria and their antimicrobial susceptibility in children with diarrhea.
Methods:
Children under 14 years old with acute diarrhea who referred to Amirkola Children's Hospital, Mazandaran, North of Iran, were enrolled during the summer and fall of 2009. From each patient, two fecal specimens were collected. Samples were cultured and bacterial isolation was done by conventional methods. Antimicrobial susceptibility was identified by disk diffusion and micro dilution methods.
Results:
One hundred-seventy two patients with the mean age of 41.8±37.6 months were evaluated. The bacteria were isolated in 48 (27.9%) cases. The most common isolated bacteria was E.coli and then shigella in both bloody and nonbloody diarrheal patients. There was a significant difference between bacteria positive specimens and WBC in stool smear (p=0.003). All isolated shigella were susceptible to Ceftizoxime and ciprofloxacin and were resistant to Cefixime. Resistant to Nalidixic acid was seen in 14% of them.
Conclusion:
The results show that E.coli was the most frequently isolated pathogen in children with bloody and nonbloody diarrhea. Ceftizoxime is a good antibiotic for shigellosis in children in our area but Cefixime is not appropriate.
