Abstract
This paper deals with biochemical and serological studies and sensitvity test to antibiotics of 43 Klebsiella strains isolated from the cases of urinary infections.
Results obtained were summarized as follows.
1) 37 strains (86%) were belonged to the known capsular types serologically and these strains were classified to 15 types by the capsular antigens.
2) All the strains were resistant to penicillin and 88% to sulfaisoxazole but to other antibiotics (chloramphenicol, tetracyclines and streptomycine) 88-100% of them were sensitive.
