[Effect of polymyxin M on intestinal microorganisms of gnotobiotic chicks]
Antibiotiki
|January 1, 1977
Abstract:
The effect of polymyxin M on the microflora artifically introduced into the digestive tract of gnotobiotic chickens was studied. It was found that polymyxin M caused dysbacteriosis in the digestive tract. Reduction of the impaired biocenosis after discontinuation of polymyxin use was rapid and practically complete.
Insights
Polymyxin M caused gut dysbacteriosis in gnotobiotic chickens. However, the digestive tract
Area of Science:
- Microbiology
- Animal Science
- Pharmacology
Background:
- Gnotobiotic animals offer a controlled model for studying microbial interactions.
- Understanding the impact of antibiotics on gut microflora is crucial for animal health and food safety.
Purpose of the Study:
- To investigate the effects of polymyxin M on the gut microbiota of gnotobiotic chickens.
- To assess the recovery of gut microbial balance after antibiotic withdrawal.
Main Methods:
- Gnotobiotic chickens were artificially inoculated with a defined microflora.
- Polymyxin M was administered to assess its impact on the introduced microbial community.
- Microbiota composition was analyzed post-treatment and after drug cessation.
Main Results:
- Polymyxin M significantly altered the gut microbial composition, leading to dysbacteriosis.
- Following the discontinuation of polymyxin M, rapid and near-complete recovery of the gut biocenosis was observed.
Conclusions:
- Polymyxin M induces significant gut dysbacteriosis in gnotobiotic chickens.
- The gut microbiota in this model demonstrates a remarkable capacity for rapid recovery after polymyxin M treatment cessation.
