Tsukamurella is a genus of bacteria gaining attention in medical settings. These environmental bacteria are commonly found in natural habitats. While widespread, certain species can affect human health. This article explores Tsukamurella’s characteristics and the infections it causes.
Understanding Tsukamurella
Tsukamurella is a genus of bacteria belonging to the family Tsukamurellaceae, first described in 1988. They are Gram-positive, non-motile, rod-shaped, and obligate aerobes, typically measuring 0.2 to 1 by 2 to 5 micrometers.
They are widely distributed in natural environments like soil, water, and activated sludge. Some species are also found as part of the human microbiota. Tsukamurella species are known for their slow-growing nature, which can sometimes make them challenging to identify in laboratory settings.
Infections Caused by Tsukamurella
Tsukamurella species are opportunistic pathogens, primarily infecting individuals with weakened immune systems or underlying health conditions. These bacteria have been linked to a variety of human infections across Europe, Asia, America, and Africa, indicating a global distribution of cases. Common manifestations include bloodstream infections (bacteremia) and those associated with indwelling medical devices.
Patients with central venous catheters or other prosthetic devices are particularly susceptible to Tsukamurella infections. The bacteria can form biofilms on these surfaces, making eradication difficult. Lung infections, such as pneumonia, are also reported, especially in individuals with pre-existing respiratory issues or compromised immunity. Other documented infections include meningitis, brain abscesses, peritonitis, and various skin and ocular infections.
Detection and Management
Identifying Tsukamurella infections involves culturing samples from infected sites or blood. Their slow growth makes laboratory identification challenging, often requiring extended incubation. Molecular analysis methods are increasingly used for definitive identification, though these methods cannot distinguish between viable and non-viable cells.
Treatment relies on antibiotic therapy. Determining the appropriate antibiotic is particularly important because species within this genus can exhibit resistance to several common antibiotics. Antibiotic susceptibility testing guides treatment decisions and ensures effective management. In cases involving medical devices, removal of the infected device may be considered alongside antibiotic treatment to resolve the infection.
