Occupational risk of Streptobacillus moniliformis infection (Rat bite fever)in conventional animal houses.

摘要

Streptobacillus moniliformis a commensal organism of the upper respiratory tract of laboratory and wild rats causes rat bite and Haverhill fever in man. To estimate the occupational hazard associated with Streptobacillus moniliformis infection in individuals working in conventional animal houses, random sampling from 250 adult rats were performed. Nasopharynx swabs were cultured on blood Agar, trypticase soy agar and trypticase soy broth media. S. moniliformis was isolated from 120 (48%) apparently healthy rats. The data suggested that there was a risk of rat bite fever in humans from laboratory rats.
