From high to low , it could be E coli , streptococci, Psudomonas and Klebsiela and others

In our clinical epidemiology lab data reveals that following the bacteria were on the list from the most common to the least common.

Escherichia coli

Staphylococcus

Enterococcus spp.

Streptococcus spp.

Enterobacter spp.

Klebsiella pneumoniae 

Raoultella terrigena

Proteus spp.

Pseudomonas spp.

Actinobacillus

Alcaligenes faecalis

Bacillus cereus

Edwardsiella hoshiniae

Micrococcus spp.

Vibrio spp.

Dear colleagues thanks for worthy answers..do you have an opinion about which media prefered to start with upon culturing?

At first culture on Blood agar and EMB or Mac agar.

Hi Weam ; 

The most common pathogens isolated from urine of diabetic patients with UTI are Escherichia coli, other Enterobacteriaceae such as Klebsiella spp., Proteus spp., Enterobacter spp., and Enterococci

see this article

For isolation 

see these articles

Escherichia coli, Staphylococcus, Klebsiella, Proteus, Pseudomonas, Bacillus and Enterococcus. The best media should be Blood agar, Cystein Lactose Electrolyte Deoxycholate deficient agar, Cetrimide and Lactose broths

Mostly Klebsiella spp., Providencia spp. and E. coli oftenly.

Very interesting question, I thankfully congratulate !!!

We routinely use Blood agar and MacConkey agar.

For details, you can refer to our book at the link.

It's E.coli. however it's based on the previous organism which caused the infection.

Is culturing on chrome agar and blood agar enough for bacterial diagnosis in UTI urine samples culture?

Staph. aureus, E.coli , Klebsiella spp. , Pseudomonas aeruginosa , Strepto. pyogenes. E.coli and Staph aureus are dominant. Use 3 corner agar plated. One with blood agar, other corner with Maconkey agar and the third corner with Brain Heart Infusion agar and use the same swab for the 3 corners and look after incubation for 48 h

Thanks prof. Gamal Enan for your response.

E coli

But it also depends on environmental factors

Yes environmental factors are of certain concern.Also immune system of the patient has sound role. Does the patient has enough antibodies and macrophages or no. Hormoal status regarding glucagon and insulin or in another meaning content of acetylcoA released from glycolysis which can defend against pathogens by formation of diacetyl.It depends also on pathogen virulence factors....etc

I ment that as regard infections in general I don't take the international trend for grant as we face different types may be our antibiotics abuse and our hygiene makes one answer doesn't fit all

Nice and sound comment from Dr.Doaa.Our hygiene means more and more.
