Forty soil samples of agriculture soil were collected from two different sites in Sohag province, Egypt, during hot and cold seasons. Twenty samples were from soil irrigated with canal water (site A) and twenty samples were from soil irrigated with wastewater (site B). This study aimed to compare the incidence of plasmids in bacteria isolated from soil and to investigate the occurrence of metal and antibiotic resistance bacteria, and consequently to select the potential application of these bacteria in bioremediation. The total bacterial count (CFU/gm) in site (B) was higher than that in site (A). Moreover, the CFU values in summer were higher than those values in winter at both sites. for plasmid-possessed bacteria were determined and the highest MICs were 1200 g/mL for lead, 800 g/mL for both Cobalt and Arsenate, 1200 g/mL for Nickel, 1000 g/ml for Copper and less than 600 g/mL for other metals. Bacterial isolates from both sites A and B showed multiple heavy metal resistance. A total of 337 bacterial isolates contained plasmids and the incidence of plasmids was approximately 25-50% higher in bacteria isolated from site (B) than that from site (A). These isolates were resistance to different antibiotics. Approximately, 61% of the bacterial isolates were able to assimilate insecticide, carbaryl, as a sole source of carbon and energy. However, the Citrobacter AA101 showed the best growth on carbaryl.
