This study analyzed bacterial isolates from infections, finding high resistance to common antibiotics like penicillin. Methicillin-resistant Staphylococcus aureus (MRSA) showed increased resistance, with amikacin and ofloxacin recommended for empirical therapy.
Area of Science:
- Clinical Microbiology
- Infectious Diseases
- Antimicrobial Resistance
Background:
- Wound and soft tissue infections are significant clinical challenges.
- Understanding causative pathogens and their antibiotic susceptibility is crucial for effective treatment.
- Distinguishing between community-acquired and nosocomial infections aids in epidemiological analysis.
Purpose of the Study:
- To identify bacterial species causing wound and soft tissue infections.
- To determine the antibiotic resistance patterns of these bacterial isolates.
- To evaluate the efficacy of different antibiotics for empirical therapy.
Main Methods:
- Bacterial isolates (n=280) from wound and soft tissue infections were collected.
- Isolates were categorized into community-acquired (n=122) and nosocomial (n=158) infections.
- Species identification and antibiotic susceptibility testing were performed using standard microbiological techniques.
Main Results:
- Staphylococcus aureus was the most common pathogen in both community-acquired (67.8%) and nosocomial (60.1%) infections.
- High resistance rates were observed for penicillin (87-92%) and ampicillin (85% in Proteus).
- Methicillin-resistant Staphylococcus aureus (MRSA) exhibited higher resistance to other antibiotics. Amikacin (80.7%) and ofloxacin (80.4%) showed the highest susceptibility rates.
Conclusions:
- Significant antibiotic resistance exists among bacteria causing wound and soft tissue infections.
- Staphylococcus aureus is a predominant pathogen, with notable resistance patterns.
- Amikacin and ofloxacin are recommended as effective empirical therapy options.

Phagocytes
Phagocytes are the frontline soldiers of the immune system. They include neutrophils and macrophages. Neutrophils are the most abundant type of white blood cell and are quickly mobilized to the site of infection. Macrophages are larger cells that patrol...
