The present study was focusing on the effect of seminal fluid infection on sperm functions and fertilizing capacity of mouse spermatozoa. Two kinds of bacteria were isolated from seminal fluid of 14 infertile patients (23-51 years) during their attendance at the Institute of Embryo Research and Infertility Treatment involves Staphylococcus aureus (Staph. aureus) and Escherichia coli (E. coli), which were identified by biochemical tests and API systems.

Sixty three isolates belonged to Bacillus spp. were isolated from 18 soil samples (uncontaminated and contaminated with hydrocarbons and fuels) collected from different locations in Baghdad and Basra governorates. All the isolates (63) were primarily screened for their ability in biosurfactant production depending on blood hemolysis activity at blood agar base, which referred that 34 isolates of the total (63 isolate) were biosurfactant producer.
