Wastewater Treatment Antibiotic Resistance in Moroccan Lagoons

535 bacterial isolates were analyzed from two lagoon wastewater treatment plants in Settat and Ouled Said, Morocco, focusing on antibiotic-resistant bacteria (ARB) prevalence and physicochemical water parameters. The study evaluates treatment efficiency by measuring reductions in total bacterial counts, coliforms, Enterococcus, and Pseudomonas, while correlating resistance patterns with factors like dissolved oxygen and pH. It provides data on resistance rates to specific antibiotics, including ampicillin and ciprofloxacin.

Use Cases

• Analyze correlations between physicochemical parameters like dissolved oxygen and pH with antibiotic resistance patterns of coliforms and Pseudomonas spp.
• Model the impact of seasonal variations and spatial location (downstream vs. upstream) on the prevalence of resistant bacterial populations.
• Assess treatment efficiency by comparing total bacterial counts and specific pathogen counts (e.g., Escherichia coli, Klebsiella pneumoniae) before and after lagoon processing.
• Investigate the relationship between high organic load, chemical oxygen demand, and increased resistance rates in bacterial isolates like Enterococcus.

Strengths

• Dataset contains 535 characterized bacterial isolates, providing a concrete sample size for analysis.
• Includes specific resistance rate measurements, such as 27.5% of coliforms resistant to ampicillin and 45.98% to ciprofloxacin.
• Correlation and factor analyses are grounded in measured physicochemical parameters (dissolved oxygen, pH, temperature, nitrate, chemical oxygen demand).
• Explicitly identifies human pathogenic species present, including Escherichia coli, Klebsiella pneumoniae, and Pseudomonas aeruginosa.

Limitations

• Small dataset size (5.5 KB) indicates limited scope, likely containing summary statistics rather than raw isolate-level data.
• Unknown row and column structure makes direct machine learning application or detailed tabular analysis difficult.
• Geographic coverage is limited to two specific sites in Morocco, limiting generalizability.
