The highest number of THB bacteria in water body was found in August at a site located in the Ergene River, and the lowest in December at a site located in the Meric (Maritsa, Evros) River. The highest number of THB in sediment was found in February at a site located in the Ergene River, and the lowest in July at a site located in the Meric River. Some physicochemical measurements have been done at the same time as the bacterial sampling to determine environmental conditions of the ecosystems. According to Spearman's correlation index, some environmental conditions were found to have a remarkable correlation with bacterial distribution (p<0.05). This research concluded that pollution load significantly increased bacteria count and played an important role in variation of bacterial quality of the rivers.eninfo:eu-repo/semantics/closedAccessMeric-Ergene River BasinHeterotrophic BacteriaWater QualityPhysicochemical ParametersArticle261A717725Q4WOS:000395724300020
