| Popis: | Rat bite fever and Haverhill fever are often difficult to diagnose in a clinical setting. This difficulty results in part from clinicians and laboratory professionals not being able to reliably recover the causative agent Streptobacillus moniliformis using culture-based methods. After utilizing an automated continuous-monitoring blood culture bottle system, we showed that the organism can be reliably cultured when a blood volume inoculum of 10 mL is used. Further, we showed that when the above recommendation is followed, sodium polyanethole sulfonate (up to a concentration of 0.05% w/v) in commercially purchased blood culture bottle formulations seems to be inactivated, allowing for the growth and detection of S. moniliformis. Herein, we offer data and methods used to overcome these clinical limitations. This is a comprehensive study of the historical collection of S. moniliformis isolates maintained by our facility and believed to be the largest of its kind to date. |
