Abstract: Bacteriae were isolated and characterized on biomorphological variations into eleven different species, (Streptococcus pyogenes, S. uberis, Staphylococcus aureus, S. intermedius, Corynebacterium diphtheriae C. pyogenes, Escherichia coli, Proteus vulgaris, Pseudomonas aeruginosa, Micrococcus luteus and Stomatococcus mucilaginosus). They varied from cocci to rod shape and were gram-positive or gram-negative. Organisms produced a variety of colonies on different media. Some were spherical, swarming and spreading colonies on agar media while in broth, granular turbidity with powdery deposits were also seen. A few species produced hemolysis ( and ) of red blood cells. Biochemical activities of different organisms revealed that among two similar species of Streptococcus,S. pyogenes had not hydrolyzed aesculin but S. uberis had hydrolyzed aesculin. The other difference between two was that the first produced β hemolysis while the second produced . Staphylococcus aureus was coagulase positive, while S. intermedius was not. However, other two species Corynebacterium diphtheriae and C. pyogenes were also biochemically tested. The first had not liquefied gelatin while the other had.
