Rise of Antibiotic Resistance in Clostridium perfringens: A Global Concern
A recent study by researchers at Nanjing Agricultural University has highlighted the alarming rise of antibiotic resistance in Clostridium perfringens, a food-borne anaerobic bacterium that causes chronic disease in humans and animals. The study, published in Current Research in Food Science, found that 39.5% of isolates were resistant to clindamycin, 32.6% to tetracycline, and 29.1% to at least two classes of commonly used antibiotics. The researchers identified 33 unique, previously uncharacterized sequence types (STs) among the 86 representative isolates, with 30.23% of these STs grouped into six clonal complexes (CCs).
Key Takeaways:
- 39.5% of Clostridium perfringens isolates were resistant to clindamycin, while 32.6% were resistant to tetracycline, highlighting the growing concern of antibiotic resistance in this food-borne bacterium.
- The study found that 29.1% of the isolates were resistant to at least two classes of commonly used antibiotics, underscoring the need for enhanced surveillance and control measures.
- The researchers identified 33 unique, previously uncharacterized sequence types (STs) among the 86 representative isolates, with 30.23% of these STs grouped into six clonal complexes (CCs).
- The study's findings emphasize the urgent need for epidemic surveillance of Clostridium perfringens in livestock settings to mitigate the risks of human transmission via environmental or food sources.
- Bacteriophages present a promising avenue as bio-antimicrobial agents for controlling the transmission of Clostridium perfringens from animal sources to humans.
Statistics:
- 398 isolates were sequenced, with 86 representing a diverse set of STs and CCs.
- 39.5% of isolates were resistant to clindamycin, while 32.6% were resistant to tetracycline.
- 29.1% of the isolates were resistant to at least two classes of commonly used antibiotics.
- 33 unique, previously uncharacterized sequence types (STs) were identified among the 86 representative isolates.
- 30.23% of these STs were grouped into six clonal complexes (CCs).
- 74/86 (80.1%) of isolates were inhibited by bacteriophage SD72, irrespective of ST types and antimicrobial resistance.
