Table 2 Proportions of antibiotic resistance and combined antibiotic resistance for Escherichia coli obtained from urine samples of healthy pregnant women compared to clinical samples from febrile patients

From: Escherichia coli from urine samples of pregnant women as an indicator for antimicrobial resistance in the community: a field study from rural Burkina Faso

  1. Differences in proportions of clinical and urine isolates were assessed using chi-square test. For smaller sample sizes (value in one of the cells ≤ 5), the Fischer exact test was used. All differences between isolates obtained from healthy pregnant women and febrile patients were statistically significant (p < 0.001)
  2. There was no statistical difference in resistance patterns between isolates growing in counts of 104 CFU/ml and 105 CFU/ml
