Antibiotic uroculture is a laboratory test requested by your doctor to identify the microorganism causing urinary tract infection and its sensitivity and resistance profile to antibiotics normally used to treat the infection, so from the test result your doctor may indicate the most appropriate.antimicrobial for the person.
This test is usually indicated when the person has signs and symptoms of urinary tract infection, but it can also be requested when SAA, bacteria, and many leukocytes are identified in the urine after the type I urine test, as these changes are indicative of an infection of the urinary tract, it is important to identify the microorganism responsible.
- The antibiotic urine culture test is used to identify the microorganism responsible for urinary change and which antimicrobial can be used most effectively in your fight.
This test is mainly indicated in case of urinary tract infection, and may be requested after the result of the type 1 urine test, SAA, or when the person has signs and symptoms of urinary tract infection, such as pain and burning when urinating and frequent need to do Pipi.Learn how to identify symptoms of a urinary tract infection.
This test is used to identify the presence and antimicrobial sensitivity profile of certain microorganisms, the main ones being:
A identificação de outros microrganismos que também podem estar relacionados com infecção do trato urinário, como Chlamydia trachomatis, Neisseria gonorrhoeae, Mycoplasma spp. e Gardnerella vaginalis, por exemplo, na maioria das vezes não é feita por meio da urocultura, sendo normalmente nesses casos solicitada a realização de coleta de secreção vaginal ou peniana para que seja feita a identificação do microrganismo e o antibiograma, ou análise da urina através de métodos moleculares.
The result of antibiotic uroculture is given as a report, indicating whether the test is negative or positive and, in these cases, which microorganism has been identified, its amount in the urine and antibiotics to which it was sensitive and resistant.
O resultado é considerado negativo quando é verificado apenas o crescimento em quantidades normais de microrganismos que fazem parte naturalmente do sistema urinário. Por outro lado, o resultado é positivo quando há aumento da quantidade de algum dos microrganismos que fazem parte da microbiota normal ou quando é verificada a presença de um microrganismo não-habitual.
As for the antibiotic, in addition to indicating whether the microorganism is sensitive or resistant to the antibiotic, it also indicates the minimum inhibitory concentration, also called CMI or MIC, which corresponds to the minimum concentration of the antibiotic capable of inhibiting microbial growth, this information being very important for the doctor to indicate the most appropriate treatment.
Escherichia coli, also known as E.coli.Coli, is the bacterium most commonly associated with urinary tract infections. When the uroculture is positive for the bacteria, the amount indicated in the urine, which is normally greater than 100,000 colonies, is indicated in the report, and to which antibiotics are sensitive.generally being Phosphocus, Nitrofurantoin, Amoxicillin with Clavulonate, Norfloxacin or Ciprofloxacin.
Além disso, é indicado o MIC, que no caso da Escherichia coli, por exemplo, é determinado que o MIC para Ampicilina menor ou igual a 8 µg/ mL é indicativo de susceptibilidade ao antibiótico, sendo o recomendado o seu uso para o tratamento, enquanto que valores iguais ou superiores a 32 µg/ mL indicam que a bactéria é resistente.
Thus, depending on the results obtained by the uroculture and antibiotic, your doctor may indicate the best treatment for the infection.
The uroculture test is a simple test performed from a urine sample, which must be collected and stored in a suitable container provided by the laboratory. To carry out the collection it is necessary to first clean the intimate area with soap and water and collect the first urine of the day, and the person must ignore the first flow of urine and collect the intermediate flow.
It is important that the sample is taken to the laboratory within 2 hours to make it viable for uroculture and antibiotics; in the laboratory, the sample is placed in a culture medium that promotes the growth of microorganisms normally present in the urine.From 24 hours to 48 hours, it is possible to check the growth of microorganisms and thus it is possible to perform microbial identification tests.
In addition, from the moment we observe the growth of microorganisms in the culture medium, it is possible to verify the number of microorganisms, and it can be indicated that it is colonization or infection, even if it is also possible to perform the antibiogram., in which the microorganism is tested for different antibiotics, checking which antibiotics are sensitive or resistant.Learn more about the antibiogram.
