Abstract:
297 materials from 446 patients with pyogenic infections were microbiologically evaluated. It was stated that Staphylococcus aureus is still the main causative organism (in spite of a downward tendency) and that its penicillin resistance is again increasing. The other gram-positive cocci occurred less frequently as pure cultures and more often as mixed cultures. The gram-negative germs increased with the increase in sensitivity to chemotherapeutical agents. 159 materials remained sterile. It must be assumed that this is in part attributable to anaerobes so far not determined. These results permit to draw the following practice-relevant conclusions: The territorial resistogram determines the use of chemotherapeutical agents; and it seems advisable not to employ penicillin in outpatient practice. Where the use of an antibiotic is indicated, treatment with oxytetracycline or gentamycin should be started.
Insights
Staphylococcus aureus remains a primary cause of pyogenic infections, with increasing penicillin resistance. Oxytetracycline or gentamicin are recommended over penicillin for outpatient antibiotic therapy.
Area of Science:
- Microbiology
- Infectious Diseases
- Clinical Medicine
Context:
- Pyogenic infections pose a significant clinical challenge.
- Microbiological evaluation of clinical isolates is crucial for effective treatment.
- Antimicrobial resistance patterns necessitate ongoing surveillance.
Purpose:
- To microbiologically evaluate clinical materials from patients with pyogenic infections.
- To identify the predominant causative organisms and their antimicrobial susceptibility.
- To inform clinical practice regarding antibiotic selection and usage.
Summary:
- A study analyzed 297 materials from 446 patients with pyogenic infections.
- Staphylococcus aureus was identified as the main pathogen, exhibiting increasing penicillin resistance.
- Gram-negative bacteria showed increased sensitivity to chemotherapeutics, while 159 samples remained sterile, possibly due to undetermined anaerobes.
Impact:
- Findings highlight the importance of territorial resistograms for guiding chemotherapeutic use.
- Recommends against penicillin use in outpatient settings due to resistance.
- Suggests oxytetracycline or gentamicin as preferred initial antibiotics for indicated treatments.
