E. coli Antibiotic Resistance in Nigerian Slaughterhouse Cattle Carcasses

A study by Chinwe E. Okoli assessed antimicrobial resistance in presumptive Escherichia coli from cattle carcasses and meat-contact surfaces at two slaughterhouses in Abuja, Nigeria. The work reports an overall prevalence of 19.4% from 540 swab samples, with all isolates exhibiting multidrug resistance and universal resistance to ampicillin. Molecular analysis detected antibiotic resistance genes including tetA, blaCTX-M, blaTEM, and blaVIM.

Use Cases

• Analyze the prevalence of multidrug-resistant E. coli isolates across 540 swab samples from carcasses and meat-contact surfaces.
• Correlate the detection of specific antibiotic resistance genes (e.g., tetA, blaCTX-M) with the reported universal resistance to ampicillin.
• Compare antimicrobial resistance patterns between isolates from the government-owned (Gwagwalada) and privately-owned (Dei-Dei) slaughterhouses.

Strengths

• Reports specific prevalence figures (19.4%) from a defined sample size of 540 swabs.
• Includes molecular confirmation data for clinically important antibiotic resistance genes like tetA and blaCTX-M.
• Provides detailed antimicrobial susceptibility testing results using the disk diffusion method.

Limitations

• The dataset is small in scale, contained within a 131.3 KB PDF file, limiting direct computational analysis.
• Data is presented in a static PDF format, requiring manual extraction for tabular or statistical use.
• Sample collection is limited to two specific slaughterhouses in Abuja, Nigeria, which may not be nationally representative.
