Abstract:

Objectives: The objectives of this study were to identify the prevalence of Staphylococcus aureus and the most common co-existing microorganisms in urinary tract infection in a non-nosocomial setting. Subsequently, the study was also aimed at establishing a relationship between Staphylococcus aureus urinary tract infection and hematuria in a non-nosocomial setting. Methodology: The study was executed at Dr. Essa Laboratory and Diagnostic Centre, Karachi, Pakistan. A total of 8090 urine specimens, collected from all branches of Dr. Essa Laboratory and Diagnostic Centre, were analyzed from October 2016 to March 2017 to identify bacterial growth positive for Staphylococcus aureus and microscopic hematuria. Results: Out of the total samples analyzed, 4168 samples (51%) showed no growth and 3922 samples (48%) were positive for bacterial growth. Out of the 3922 positive samples, 711 samples (18.12%) were positive for Staphylococcus aureus growth and co-existing microorganisms. Isolated Staphylococcus aureus was found to be in 463 samples (65.11%) out of the 711 showing bacterial growth. Other significant organisms causing a co-infection with Staphylococcus aureus were Enterococcus (12.5%), E. coli (7.59%), Candida (5.62%) and Klebsiella species (5.06%). Out of the 463 samples containing isolated Staphylococcus aureus, 81 samples (17.49%) showed significant microscopic hematuria. When Staphylococcus aureus co-existed with Enterococcus and E. coli, microscopic hematuria was positive and was insignificant in samples exhibiting growth of Candida and Klebsiella with Staphylococcus aureus. Conclusion: Staphylococcal urinary tract infections can be observed in a non-nosocomial setting. Staphylococcus can co-exist with other microbes, causing a polymicrobial urinary tract infection. Isolated Staphylococcal aureus infection can cause hematuria however polymicrobial infections are not accompanied by hematuria. samurnasabir@gmail.com
