Molecular diagnosis of arthritis due to streptobacillus moniliformis

Area of Science:

• Microbiology
• Molecular Diagnostics
• Clinical Laboratory Science

Background:

• Arthritis can be caused by various bacterial pathogens.
• Identifying fastidious bacteria like Streptobacillus moniliformis can be challenging in clinical settings.
• Increased human-rod interactions raise concerns for zoonotic disease transmission.

Purpose of the Study:

• To report the identification of Streptobacillus moniliformis as an etiological agent of arthritis.
• To evaluate the utility of a 16S rDNA molecular kit for identifying this bacterium in a clinical laboratory.
• To highlight a diagnostic approach for arthritis cases with unclear clinical presentation.

Main Methods:

• Bacterial identification using a commercial 16S rDNA molecular kit.
• Application of molecular diagnostics in a clinical laboratory setting.
• Analysis of clinical case data for arthritis etiology.

Main Results:

• Streptobacillus moniliformis was successfully identified as the causative agent of arthritis.
• The 16S rDNA molecular kit proved effective for identifying this fastidious Gram-negative rod.
• The diagnostic method showed suitability for cases lacking clear clinical indicators.

Conclusions:

• 16S rDNA molecular identification is a valuable tool for diagnosing Streptobacillus moniliformis-induced arthritis.
• This molecular approach is particularly useful when clinical signs are non-specific.
• The method supports timely and accurate diagnosis in the context of increasing human-animal contact.
