دراسة الخصائص الفيزيوكيميائية و البكتيرية لمياه شاطئ البحر برجيش في مدينة المهدية-تونس

الملخص EN

Bacterial and physicochemical properties of seawater have a crucial impact on human health.

Data about these characteristics in Rejiche Cost, a touristic and a fishing area in Tunisia are limited.

Thus, in the present study, seawater and sediment samples were collected during four successive months.

Various physicochemical and microbial properties were screened to ascertain the safety of water for swimming.

Antimicrobial susceptibilities were determined using disc diffusion method.

Total suspended solid, turbidity, absorbable organic halogen, chemical oxygen demand and biochemical oxygen demand were higher than accepted norms in Tunisia.

Enterococcus faecalis was detected in all the sites indicating a human fecal contamination.

All isolated strains were highly resistant to rifampicin, gentamicin, chloramphenicol, ampicillin and azithromycin.

Our results showed that the situation in Rejiche cost is alarming.

Treatment of wastewater discharges requires intensive monitoring to improve seawater quality and to respect the required healthy standards.
