Six randomly airborne samples from delivery rooms of three hospitals (Algmhory, Althwrah and Alsabeen hospitals).

Bacteria isolates were identified as Staphylococcus aureus, Staphylococcus epidemidis, Micrococcus sp., Bacillus sp., Pseudomonas aeruginosa, Corynebacterium sp., Klebsiella sp., Lactobacillus sp. and Proteus mirabilis. The highest percentage of bacterial isolates was recorded in Alsabeen hospital as 66.2%. Staphylococcus was the most dominant organism isolated from the delivery rooms in all examined hospitals (37 isolates, 56.9%), while the lowest percentages were: Lactobacillus (two isolates, 3.1%), Klebsiella and Proteus (one isolate, 1.5%) for each
