In short- the most common are the

Gram-negative bacilli (Escherichia coli, Proteus, Klebsiella, others),

Gram-positive organism (Staphylococcus saprophyticus, Staph. aureus etc).

Others include Chlamydia trachomatis, Niesseria gonorrhoeae, Trichomonas vaginalis

E. coli, Klebssila, Protus and Staph.

I have no idea...

Escherichia coli and Staphylococcus. Saprophyticus account for about 80% of

community- acquired uncomplicated urinary tract infections, particularly in women under 50 years of age.Other Gram-negative pathogens, including Pseudomonas spp., Enterobacter spp., Serratia spp., Citrobacter spp., and urease-producing Klebsiella spp., Proteus spp., Corynebacterium urealyticum , and Providencia spp. are also involved in this type of infection.Staphylococcus aureus, Staphylococcus haemolyticus and Group B haemolytic Streptococci are implicated in urinary tract infections. The numbers of fungal urinary tract infections are increasing particularly those caused by Candida spp., and, to a lesser extent, by Aspergillus spp. and Gram-positive bacteria, including Enterococcus spp. and Staphylococcus spp.

Escherichia coli

Urinary tract infections (UTIs) caused by Escherichia coli are the most common types of infections in women.

Chapter The Pathogenesis of Escherichia coli Urinary Tract Infection

There is a long list of organisms that cause UTI. A few of them are as follows- Escherichia coli, Klebsiella, Staphylococcus aureus, Staphylococcus saprophyticus, Chlamydia trachomatis, Mycoplasma genitalium, Pseudomonas, Enterococcus, Gonococcus, Candida albicans etc.

Among them Escherichia coli is the most frequently isolated one.

Escherichia coli account to 80% to 85% of the infection followed by Staphylococcus species that constitutes to 10% to 15%. In addition, Klebsiella, Pseudomonas, Proteus and Enterococcus species play a minor role in conferring the infection.

According to the article that I read about Bacteria Isolated among the patients, E. coli is 55.38%, It was the most common isolated pathogen. then Enterobacter spp. followed by 29.61%. The rest of the bacteria were rarely isolated which are Pseudomonas spp. 4.9%, S. aureus 3.21%, Enterococcus spp. 2.3%, fungi 1.5% and Klebsiella 0.48%. Patients are more likely to suffer from the causative agent Escherichia coli and Enterobacter spp.

Another article I read about is Urinary Tract Infection among Outpatients, The most common pathogenic organism isolated in UTI is Escherichia coli. E. coli has frequent number of isolates, which is 80% from the urine sample of the outpatients with primary UTI or recurrent UTI. It is followed by Staphylococcus saprophyticus which is 5-15%. The rest are causative agents from nosocomial infection and they rarely cause infection outside of the hospital. Klebsiella spp., Proteus mirabilis, Pseudomonas spp. and Candida spp which are found to be 5-10% of the isolates.

The most common organism isolated from patients suffering from Urinary Tract Infections includes Escherichia coli, Enterococcus, Klebsiella, Pseudomonas, and other Enterococcus or Staphylococcus spp.

From the research conducted in Nepal, the data showed out of 1599 urine samples, the most common pathogen seen was E. coli which recorded 58.7%, followed by Klebsiella pneumoniae with 22.5%.
