ABSTRACT
The study entailed bacteriological study of Suppurative Otitis Media. The disease is a major health problem in underdeveloped countries including Yemen Arab Republic.260 cases [154 males and 106 females] suffering from continuous or recurrent ear discharge for more than two days, were the subject of this study. Most of the patients were infants and children and only few of more than 12 years old .Bacteria were isolated from 248 [95%] of cases. Staphylococcus aureus were recovered from [34.2%] of cases followed by Pseudomonas aeruginosa [19.2%], proteus species [11.5%], Streptococcus pyogenes [11 .5%], Streptococcus fecalis [6.9%], Escherichia coli [3.5%], Klebsiella species [3%], Haemophilus influenzae [3.5%], Streptococcus viridence [1.1%] and Dephtheriods [0.8%]. Mixed infections were recovered in [3.8%] of cases and no growth in [4.6%] of cases.The susceptibility of isolated organisms showed high resistance of proteus species to most tested antimicrobial agents. Amikacine was found the most effective [81%] followed by Gentamycin [73%]. The majority of the isolated proteus strains were resistant to the rest of the tested antibiotics
