Review: Good product if you know what you're doing - We're using these to pre-test our 5-yo Doberman's urine for e-coli after she nearly died from an undiagnosed e-coli UTI in mid-2022. She gave no indications of illness until the infection became systemic and she crashed. Emergency care & hospitalization was able to stabilize her but she required blood transfusions, IV fluids, stomach feeding tube and a range of antibiotics to simply maintain her status until the lab cultures came back. After 3 days being near death & hospitalization the lab results came back with a definitive result for e-coli, the ER vets were able to medicate her with the correct antibiotics. Within 12 hours of the correct IV antibiotic administration she was 70% back to her normal self. 36 hours after the initial IV antibiotic she came home and has fully recovered. However, she is a very strong and stoic type and doesn't display symptoms or behaviors like most female dogs when she has a UTI. So we decided that I would set up a small, secure home lab to periodically culture her urine using MacConkey media, an incubator, digital PWM thermal controller and various other tools in an attempt to identify a problem before it becomes life threatening. After researching the process and best practices from Texas A&M's, Oklahoma State's and Penn State's veterinary colleges, we have successfully tested her using these MacConkey plates three different times. Each time we incubate a sample from her and a control sample from her fecal matter --- a guaranteed source of e-coli and other gram-negative bacteria for comparison. Each time the Control sample shows colony growth at the 12-hour point, and continues to grow for the entire 96-hour period. The actual urine-derived sample that is incubated simultaneously has shown zero growth for the same 96-hour period. This is the best result, urine is naturally sterile. The entire setup, including these MacConkey plates cost less than $150 to set up, not including a microscope. Compared to the cost of each veterinary urine culture lab test of $250+ or a $20k veterinary hospital bill, $150 and some time researching how to perform these simple tests is a pittance. **One of the benefits of using this agar is that a microscope is not necessary to confirm the presence of gram-negative bacteria, which can help your vet begin treatment while a true diagnostic culture is performed at a lab.** If you do not observe bacterial colony growth does not mean there isn't a bacterial infection, it may be a gram-positive bacterial or something that will not culture well on MacConkey. But we use this as an early warning that Freyja may have a problem that she can't tell us about.
Review: Does not work - Nothing grew, even the bread mold test. The mold stayed on the bread and would not spread to the “agar.” The other dishes in my incubator cultivated.

### ⭐⭐⭐ 3 contaminated plates
*by D***D on January 3, 2024*

Thank goodness for surplus as I could modify the experiment to use the remaining 7 plates as 3 plates arrived contaminated as seen in pic. I have used the remaining 7 and will report back on how well E. Coli grew on this agar. The 7 I used were in good condition w/o defects.
