S. saprophyticus has been considered contaminated bacteria. but, recently it was reported that those organisms are capable of causing infection of urinary tract. So, the appreciation of the significance of coagulase negative staphylococci infection is being rapidly expanded. Thus, In clinical laboratories, it has become more important to accurately differentiate staphylococci from nonpathogenic micrococcus.
This study was performed to investigate the status of infected Patient with S. saprophyticus. Total 2,234 urine specimen was cultured and 71 young woman with urethritis symptom was studied by urine culture an4 urine sediment microscopy for evaluate the age prevalance.
The results obtained are summarized as follows:
1. Among the total 2,234 urine culture, the growth rate was 42.3%. The most common strain was E. coli and other Gram negative baccilli. The growth rate of S. saprophyticus was 0.2%.
2. Among the 71 young woman with urethritis symptom, The growth rate of S. saprophyticus was 4.2%.
3. The isolation of S. saprophyticus was from the patient with lung ca, sepsis, pregnancy and urethritis. Microscopic findings disclose epithelial cells and WBC.
4. Sensitivity pattern of S. saprophyticus disclosed that it was susceptible in penicillin, Sx. T., Ampicillin and sulfonamide, but resistant strain was founded in Amikacin, cephalothin, G. M. and K. M.
From the above results, We could conclude that S. saprophyticus are not simple contaminant but important pathogen in young woman and other conditions.
So, it need identify the S. saprophyticus by more simple and scientific method in clinical specimen.
