Water and water resources is very important for maintaining an adequate food supply and a productive environment for the all living organisms (Zeyneb et al., 2020). Availability and accessibility of clean water does not only perform a vital role in social welfare and economic development, but also it is an important element in health and poverty reduction.
Estuarine and coastal areas are vulnerable to anthropogenic activities (Yuan Li et al., 2016 ; Kennish et al., 2019), which in turn affect the water quality of mangrove ecosystems. Various contaminants, such as heavy metals and pharmaceutical pollutants, have been studied in these environments (Lawson et al., 2011 ; Yuan Li et al., 2015 ; Bayen et al.,
2016). However, research on emerging contaminants like antibiotic-resistant bacteria remains limited, despite their urgent nature. According to some projections, infections caused by antibiotic-resistant bacteria could contribute to approximately 10 million deaths worldwide by 2050 (Serwecinska et al., 2020). This wastewater most often harbours a variety of pathogenic microorganisms, such as viruses, bacteria and antibiotic resistance genes ((Serwecinska et al., 2020).
This poses a significant public health threat to local populations and disrupts the ecological balance of the ecosystem. Therefore, investigating these antibiotic resistant pathogenic bacteria is crucial for better managing this global health challenge and ensuring the health
of aquatic ecosystems. Thus, the aim of this study was to assess the prevalence of antibiotic resistant pathogens bacteria from the wastewater of mangroves ecosystems in the Estuaire province of Gabon, with a view to encourage the monitoring of water quality and antibiotic-resistant bacteria.
