Abstract EN
The current work aimed to study the distribution of B.
subtilis and B.
cereus in soils of Damascus zone and focused on the antibacterial activity of Bacillus species against Staphylococci species which were isolated from pathogen and soil’s samples.
The study showed that the rate of the distribution of B.
subtilis was (65.71%) and it was more than the rate of distribution of B.
cereus which was (35.29%) in the soil, and the rate of distribution of Staphylococci were between (10 – 20%).
The antibacterial activity was studied for two species of B.
subtilis, and two species of B.
cereus against 35 species of Staphylococci which isolated from soil and deferent pathogen samples: ear, urine, Bronchitis excretions, Liver’s wash, CSF, Blood, Abscess, Furuncle, Pus, CV shant, Wounds.
The results showed that B.
subtilis which isolated from the soil of zone of Al-tall has more antibacterial activity which gives bigger inhibition zone against all strains of Staphylococci which were isolated from soil and pathogens (100%), whereas another strain which was isolated from the soil of zone of AL-Rabwah didn’t give antibacterial activity against some of these strains of Staphylococci (38.86%, 27.27%).
In addition, two species of B.
cereus didn’t have any antibacterial activity towards most strains of Staphylococci, except six of it (31.42%).
With respect to strains of Staphylococci which was isolated from soil, B.
subtilis of Al-tall has more antibacterial activity which give bigger inhibition zone (10-21 mm) against all of strains of Staphylococci which isolated from different soil except S.
epidermidis (0 mm) which isolated from Adawee, while another species which isolated from the soil of AL-Rabwah gave antibacterial activity against some of these strains of Staphylococci.
In addition, two species of B.
cereus had antibacterial activity towards three strains of Staphylococci, but no activity towards four strains of it, and there is a significant difference between B.
subtilis1 and Bs2, Bc1, Bc2 in almost strains of Staphylococci (P< 0.05).
