[Etiological structure and antibiotic sensitivity of the causative agents of puerperal endometritis].

The study revealed the dominating role of aerobic-anaerobic microbial associations and in particular the specific role of anaerobic gram positive cocci in development of puerperal endometritis. The data suggested that a definite level of the uterus cavity contamination with microbes, not lower than 10(4)-10(5) CFU/ml or a large number of bacterial associates, not less than 3 was necessary for endometritis development. It was confirmed that pathogenicity of anaerobes increased in the presence of aerobic bacteria. It is concluded that quantitative methods for detecting the main causative agents of endometritis are needed. A set of antibacterial drugs for rational antibacterial therapy of puerperal endometritis is recommended.
