Neomycin – 30 μg Antibiotic Disc – Bioanalyse

Neomycin – 30 μg Antibiotic Disc – Bioanalyse is a paper disc impregnated with 30 micrograms of neomycin, a broad-spectrum aminoglycoside antibiotic. It is used in the disc diffusion method of antimicrobial susceptibility testing to determine the susceptibility of bacteria to neomycin.

Neomycin is effective against a wide range of bacteria, including both Gram-positive and Gram-negative bacteria. It is used to treat a variety of infections, including:

• Urinary tract infections
• Gastrointestinal infections
• Skin and soft tissue infections
• Respiratory infections
• Sepsis

Neomycin is also used to prevent infections before surgery.

Interpretation of results:

| Zone of inhibition | Interpretation | |—|—|—| | ≥ 17 mm | Susceptible | | 13-16 mm | Intermediate | | < 13 mm | Resistant |

It is important to note that the disc diffusion method is only a semi-quantitative method for testing the susceptibility of bacteria to antibiotics. For more accurate results, other methods such as broth microdilution or agar dilution should be used.

The Neomycin – 30 μg Antibiotic Disc – Bioanalyse is a valuable tool for the diagnosis and treatment of a wide range of bacterial infections. However, it is important to be aware of the potential side effects of neomycin before using it. Neomycin can cause side effects such as:

• Nausea
• Vomiting
• Diarrhea
• Abdominal pain
• Headache
• Dizziness
• Rash

In rare cases, neomycin can cause serious side effects such as:

• Kidney damage
• Hearing loss
• Allergic reactions

Limitations of the Neomycin – 30 μg Antibiotic Disc – Bioanalyse:

• The disc diffusion method is only a semi-quantitative method for testing the susceptibility of bacteria to antibiotics. For more accurate results, other methods such as broth microdilution or agar dilution should be used.
• The disc diffusion method is not able to detect all bacteria that are resistant to neomycin. For example, some strains of Pseudomonas aeruginosa are resistant to neomycin, but they may not produce a zone of inhibition around a neomycin disc.
• The disc diffusion method can be affected by the type of agar plate used, the incubation temperature, and the inoculum density. Therefore, it is important to follow standardized procedures when performing the disc diffusion test.

Additional information about neomycin:

Neomycin is a safe and effective antibiotic for most people when used as directed. However, it is important to be aware of the potential side effects of neomycin before using it. Neomycin is not recommended for people who are allergic to neomycin or other aminoglycoside antibiotics. Neomycin is also not recommended for people with kidney problems or hearing problems.
