  • Figure 1. E. coli on eosin methylene blue (EMB) agar
  • Figure 2. Prevalence of E. coli isolate from tested chicken meat samples
  • Figure 3. Serotypes of E. coli (n=20) isolated from positive chicken samples
  • Figure 4. Screening of shiga-like toxin (SLT) – subunit (B) in tested strains. Strain 1 showed a lower density of the amplified gene. Lane (L) represents a standard DNA ladder with 100-3000 bp range
  • Figure 5. Screening of heat-labile toxin (LT) gene in genomic DNA (A) and plasmid preparations (B). The target gene was detected at a molecular weight of ~ 200 bp in the genomic DNA of strains (1) and (2)
  • Figure 6. Gentamycin-resistance gene screening: strains screened showed the target fragment of molecular weight ~ 856 bp corresponding to gentamycin-resistance (aac C2) gene. A minor band with 300 bp was visualized in strains 1 and 2
  • Figure 7. Ciprofloxacin-resistance gene screening: (A) on genomic only strain (1) showed amplification at 1kb size. (B) plasmid
