Antibiotic-Resistant Bacteria in Moroccan Wastewater Effluents

A study of 535 bacterial isolates from treated wastewater in Settat and Ouled Said, Morocco, assessing physicochemical characteristics and antibiotic-resistant bacteria (ARB) prevalence. The data includes resistance rates to antibiotics like ampicillin and ciprofloxacin, and correlations with parameters like dissolved oxygen and pH. It was authored by Habiba Raqraq and published in 2026.

Use Cases

• Analyze correlations between physicochemical parameters like dissolved oxygen, pH, and antibiotic resistance patterns of bacterial isolates.
• Model spatial and seasonal variations in ARB prevalence, using data on resistance rates from colder months and downstream regions.
• Investigate resistance rates of specific pathogenic species such as Escherichia coli, Klebsiella pneumoniae, and Pseudomonas aeruginosa to antibiotics like ceftazidime and imipenem.
• Assess the impact of water quality factors like temperature, nitrate, and chemical oxygen demand on the variance of ARB dynamics through factor analysis.

Strengths

• Contains data on 535 bacterial isolates, providing a specific sample size for analysis.
• Includes quantified antibiotic resistance rates, such as 27.5% to ampicillin and 45.98% to ciprofloxacin for coliforms.
• Factor analysis explains 90.53% of the overall variance, indicating strong explanatory power for the measured parameters.
• Explicitly identifies human pathogenic species like Escherichia coli, Klebsiella pneumoniae, and Pseudomonas aeruginosa.

Limitations

• The dataset is very small at 5.5 KB, indicating limited scope and likely a small number of observations or variables.
• No column names or sample data are provided, making it difficult to assess the exact structure and variables available.
• Geographic coverage is limited to two specific sites in Morocco, reducing generalizability to other regions.
