[Clinical, epidemiologic and bacteriological characteristics of urinary tract infections due to Staphylococcus saprophyticus in the central part of Tunisia].

AIM: We assess the clinical, epidemiologic and bacteriological aspects of urinary tract infections due to S. saprophyticus through a sample collected in the central part of Tunisia.

METHODS

Retrospective study, related to 92 strains of S. saprophyticus, isolated among positive urinary specimens in 2006. Considered data were: sex, age, original departments, symptoms, type of urinary tract infection, diagnosis date and susceptibility of strains to antibiotics.

RESULTS

Patients are young women in 98% (average age: 31.5 years) with cystitis in 99%. They are outpatients in 90%. S. saprophyticus represents 2.8% of all uropathogens; it is the first cocci with positive Gram (28.2%). Any seasonal variation is noticed. S. saprophyticus has shown higher susceptibility to antibiotics than other staphylococci; cotrimoxazole, fluoroquinolons and nitrofurans represent the best treatment.

CONCLUSION

S. saprophyticus is responsible of cystitis in young women. There is no seasonal variation in our area. This community staphylococci is very susceptible to antibiotics.
