Bacteria Causing Otitis Media in some Private and Public centers in Thamar governorate - Yemen

Introduction: Breast cancer is one of the most common cancers worldwide. The reproductive hormone prolactin is produced primarily by the pituitary gland and in lesser amounts by several other tissues, including breast tissue. Prolactin plays a central role in breast development, differentiation, and lactation, but experimental data suggest that, in addition to having a role in normal development, prolactin may have pro-carcinogenic effects. Aim: To identify the common bacteria causing OM and to determine its sensitivity to commonly used antibiotics. Also to identify some factors associated with OM. Methods: Two hundred samples of ear discharge from patients with OM were collected and examined during the period from February 2010 to February 2011. Each patient filled a questionnaire. Results: Distribution of OM according to region of living was statistically significant (P value = 0.001). Bacteria isolated in this study were mainly gram positive (52.8%); Staphylococcus aureus was the most common isolate (43.4%). Conclusions: The bacteria isolated in this study were mainly gram positive (52.8%); Staphylococcus aureus was the most common isolate (43.4%). 47.1% of the bacteria isolated was gram -ve .Pseudomonas aeurginosa represent the majority with 29.3%. Ofloxacin and Gentamicin were the most effective antibiotics for most bacterial isolated
