High prevalence of Pseudomonas species in soil samples from Ternate Island-Indonesia.

ABSTRACT

In the present study, Ten soil samples were examined and the pH of the soil was recorded. For bacterial isolation, a sterile nutrient and blood agars were used. Gram stain and biochemical tests were done for identification. A total of 384 genus were isolated, 314 (81.8%) were identified as Pseudomonas species of which 245 (78.0%) were Pseudomonas aeruginosa, 42 (13.4%) were Pseudomonas fluorescens, 13 (4.2%) were Pseudomonas mallei, 10 (3.1%) were Pseudomonas putida and 4 (1.3%) were Pseudomonas syringe and are regarded as pathogenic and harmful to man, animal and plants. This study shows that Pseudomonas aeruginosa had a high adaptation capability to grow in soil samples from Ternate, Indonesia. The rest of the bacterial isolates (18.2%) were identified as follows 24 samples (6.2%) were Micrococcus, 23 samples (6.0%) were E. coli, 12 samples (3.1%) were Pasteurella and 11 samples (2.9%) were Staphylococcus. Pencillium was also isolated.
