Pseudomonas aeruginosa is commonly known to infect sites such as the urinary tract, skin, respiratory tract, and blood of humans and other mammals; these infections often spread rapidly and range from chronic to acute. Pseudomonas aeruginosa is highly capable of forming biofilms which aid in antibiotic resistance and long term survival. This study evaluated 14 human isolates and 32 equine isolates to determine if there is a correlation between biofilm rate of attachment and chronic vs. acute infection. The study involved a series of 30 minute and 18 hour assays on all isolates, to evaluate biofilm rate of attachment at different time points. The isolates identified as having the highest rate of attachment such as UK1 (tissue sample), UK5(unknown) UK8 (unknown), HG6 (equine stallion pre-fossa cx), HG7 (equine uterus culture), HG4 (equine uterus culture), and HG15 (equine incision site culture). All 18 hour averages were found greater than 30 minute averages, with the exception of HG18 (stallion ulceration on reproductive organs). Further studies on this topic be very beneficial for the scientific community, because of the prevalence of P. aeruginosa in the United States, as well as all over the world.
