Methods
Also provided herein are methods of diagnosing a urinary tract infection in a subject and determining susceptibility of bacteria and/or fungus causing the urinary tract infection to an antibiotic and/or antifungal agent.
In some embodiments, the methods provided herein include (a) disposing a volume of urine from a subject into a first capped transparent or translucent sterile vessel (e.g., any of the first capped transparent or translucent sterile vessels described herein); (b) disposing a volume of urine from the subject into a second capped transparent or translucent sterile vessel (e.g., any of the second capped transparent or translucent sterile vessels described herein) containing at least one antibiotic and/or at least one antifungal agent (e.g., any of the antibiotics and/or antifungal agents described herein) (c) incubating the first capped transparent or translucent sterile vessel and the second capped transparent or translucent sterile vessel for a period of time; and (d) determining turbidity of the urine in the first capped transparent or translucent sterile vessel and the second capped transparent or translucent sterile vessel after the period of time. In some embodiments, the method further includes disposing a volume of urine from the subject into at least one additional capped transparent or translucent sterile vessel containing at least one antibiotic and/or at least one antifungal agent that is different from the at least one antibiotic and/or at least one antifungal agent that is present in the second capped transparent or translucent sterile vessel.
The presence or absence of turbidity in the urine can be used to identify a subject having a urinary tract infection. For example, presence of turbidity in the urine in the first capped transparent or translucent sterile vessel after the period of time can identify that the subject has a urinary tract infection. In some embodiments, the lack of detectable turbidity in the urine in the first capped transparent or translucent sterile vessel after the period of time identifies that the subject does not have a urinary tract infection.
In some embodiments, decreased turbidity in the urine in the second capped transparent or translucent vessel after the period of time compared to the turbidity of the urine in the first capped transparent or translucent sterile vessel after the period of time identifies that the bacteria or the fungus causing the urinary tract infection is susceptible to treatment with the at least one antibiotic and/or the at least one antifungal agent present in the second capped transparent or translucent sterile vessel. In some embodiments, similar turbidity in the urine in the second capped transparent or translucent vessel after the period of time compared to the turbidity in the urine in the first capped transparent or translucent sterile vessel after the period of time, identifies that the bacteria or the fungus causing the infection is not susceptible to the treatment with the at least one antibiotic and/or the at least one antifungal agent present in the second capped transparent or translucent sterile vessel.
In some embodiments, the subject is identified as having a urinary tract infection and the bacteria or the fungus causing the urinary tract infection is identified as being susceptible to treatment with the at least one antibiotic and/or the at least one antifungal agent present in the second capped transparent or translucent sterile vessel. In some embodiments, the subject is identified as having a urinary tract infection and the bacteria or the fungus causing the urinary tract infection is identified as being susceptible to treatment with the at least one antibiotic and/or the at least one antifungal agent present in the at least one additional capped transparent or translucent sterile vessel.
In some embodiments, the subject is identified as having a urinary tract infection and the bacteria or the fungus causing the urinary tract infection is identified as not being susceptible to treatment with the at least one antibiotic and/or the at least one antifungal agent present in the second capped transparent or translucent sterile vessel. In some embodiments, the subject is identified as having a urinary tract infection and the bacteria or the fungus causing the urinary tract infection is identified as not being susceptible to treatment with the at least one antibiotic and/or the at least one antifungal agent present in the at least one additional capped transparent or translucent sterile vessel.
In some embodiments, the subject is identified as not having a urinary tract infection.
In some embodiments, the methods provided herein include (a) disposing a volume of urine from a subject into a first capped transparent or translucent sterile vessel (e.g., any of the first capped transparent or translucent sterile vessels described herein) containing at least one pH sensitive dye (e.g., any of the pH sensitive dyes described herein) (b) disposing a volume of urine from the subject into a second capped transparent or translucent sterile vessel (e g., any of the second capped transparent or translucent sterile vessels described herein) containing at least one antibiotic and/or at least one antifungal agent (e.g., any of the antibiotics and/or antifungal agents described herein) and the at least one pH sensitive dye; (c) incubating the first and second capped transparent or translucent sterile vessels for a period of time; (d) determining a color change of the urine in the first and second capped transparent or translucent sterile vessel after the period of time as compared to a control capped transparent or translucent vessel comprising sterile water or a pH neutral buffered solution (pH of 6 to 8) and the at least one pH sensitive dye, wherein detection of a significant color change in the urine in the first capped transparent or translucent sterile vessel after the period of time identifies that the subject has a urinary tract infection and detection of no significant color change in the urine in the second capped transparent or translucent vessel after the period of time compared to the control capped transparent or translucent vessel after the period of time identifies that the bacteria or the fungus causing the urinary tract infection is susceptible to treatment with the at least one antibiotic and/or the at least one antifungal agent present in the second capped transparent or translucent sterile vessel; detection of a significant color change in the urine in the first capped transparent or translucent sterile vessel identifies that the subject has a urinary tract infection and detection of a significant color change in the urine in the second capped transparent or translucent vessel after the period of time as compared to the control capped transparent or translucent vessel after the period of time, identifies the bacteria or the fungus causing the infection is not susceptible to the treatment with the at least one antibiotic and/or the at least one antifungal agent present in the second capped transparent or translucent sterile vessel; or detection of no significant color change in the urine in the first capped transparent or translucent sterile vessel after the period of time as compared to the capped transparent or translucent vessel identifies the subject does not have a urinary tract infection. As used herein, a pH sensitive dye is meant a dye that is capable of changing color when shifting from a pH of 6 - 8 to a pH of less than 6 and/or shifting from a pH of 6-8 to a pH of greater than 8.
