Slow Growing Gram Negative Rods: A Potential Emerging Infectious Pathogen

The identification of Haematospirillum jordaniae, a slow growing gram negative rod, has been a significant breakthrough in the field of microbiology. This bacterium was first recognized as a human pathogen by the Centers for Disease Control and Prevention (CDC) and has since been isolated from 10 different states over the course of 10 years.

The CDC's Special Bacteriology Reference Laboratory received samples of this organism between February 2003 and October 2012, before it was initially published. The bacterium was found to be a gram-negative, spiral-shaped aerobe belonging to the family Rhodospirillaceae.

One notable case involving H. jordaniae occurred in September 2016, when a 35-49 year old man sought medical attention for worsening pain, redness, and swelling of his right lower extremity. The patient had an open wound on his right shin and reported having cut stones three weeks prior to developing symptoms. He was initially treated with intravenous clindamycin and admitted to the hospital for further treatment.

The patient's case highlights the importance of seeking medical attention promptly, as he ignored initial symptoms such as swelling, erythema, and fever before being hospitalized. The diagnosis of H. jordaniae was made possible through blood cultures and identification by the Delaware Public Health Laboratory (DPHL).

Understanding the routes of infection for H. jordaniae is crucial in preventing further outbreaks. As a slow growing gram negative rod, it is essential to identify potential sources of transmission, such as contaminated water or stone chips.

In conclusion, Haematospirillum jordaniae is a potentially emerging infectious pathogen that requires attention and research from the scientific community. Further studies are needed to understand its routes of infection and prevention strategies to prevent future outbreaks.
