Fungal urinary tract infection is very common in women. And many bacteria are also responsible to occurring infection into female urinary tract leading to complicated UTI.
Bacteria are the primary organisms that cause UTIs. Most common bacteria that cause UTIs include: Escherichia coli and Staphylococcus saprophyticus. About 80-90% of urinary tract infections are caused by Escherichia coli (E. coli). This bacterium is normally found in the digestive tract and is present on the skin around the rectal area. About 10-20% of urinary tract infections are caused by the Staphylococcus saprophyticus. Infections caused by this bacteria have a seasonal variation, with a higher incidence in the summer and fall than in the winter and spring.
And about 5% or less of urinary tract infections are caused by other bacteria. Gram-negative microorganisms causing UTIs include Proteus, Klebsiella, Citrobacter, Enterobacter, and Pseudomonas spp. Gram-positive microorganisms such as Enterococcus faecalis can also infect the urinary tract.
Microorganisms such as Chlamydia and Mycoplasma may also cause UTIs in both men and women. Unlike E. coli, Chlamydia and Mycoplasma may be sexually transmitted, and infections require treatment of both partners.
