Bacteriological examination of the conjunctiva of the eye with identification of pathogens and determination of antibiogram using automatic analyzers AF300; Scan4000 according to EUCAST methodology

Bacteriological examination of biomaterial from the conjunctiva of the eye and determination of antibiotic sensitivity is an important step in the treatment of eye infections. This process helps to identify pathogens and determine which antibiotics are most effective in overcoming the infection. Let's look at the main steps of this study.

1. Collection of biomaterial: The first step is to collect the biological material. For this, a sterile cotton swab is used, which is touched to the conjunctiva of the eye. Special care is required to avoid contamination with other bacteria.
2. Processing of the biomaterial: The collected material is transferred to the laboratory, where it is processed. The cotton swab is placed in a special buffer solution that helps preserve the bacteria for further analysis.
3. Bacterial isolation: After processing, the material is used on nutrient media to isolate bacteria. This allows bacterial cultures to be grown for further research.
4. Bacterial identification: Using microscopy and biochemical tests, lab technicians identify the types of bacteria present in the conjunctiva of the eye. This is important for choosing the right antibiotic for treatment.
5. Antibiotic susceptibility testing: Special tests, such as antibiotic diffusion susceptibility (antimicrobial susceptibility), are used to determine the susceptibility of bacteria to antibiotics. These tests help determine which antibiotics are most effective for treating a particular infection.
6. Antibiotic selection: Based on the results of antibiotic sensitivity, the doctor prescribes the optimal drug for the patient's treatment. It is important to consider not only the effectiveness of the antibiotic, but also the possibility of allergic reactions and other factors.
7. Monitoring Treatment: After prescribing an antibiotic, it is important to regularly monitor the patient's condition and determine the effectiveness of the treatment. If necessary, the antibiotic may be changed to achieve better results.

In conclusion, bacteriological examination of the conjunctiva of the eye and determination of antibiotic sensitivity are an important part of the diagnosis and treatment of ocular infections. This approach allows for effective and individualized treatment, increasing the chances of a rapid recovery of the patient.
