NOCARDIA ISRAELI Meaning and
Definition
-
Nocardia israeli is a species of bacteria that belongs to the Nocardia genus and is commonly found in the soil and organic matter. It is a Gram-positive, aerobic, and filamentous bacterium that often appears as branching filaments or hyphae, resembling fungal structures. Nocardia israeli is known to have a high resistance to environmental stresses, including extreme temperatures and desiccation, which allows it to thrive in various habitats.
This bacterium is clinically significant as it can cause a range of infections in humans, particularly in individuals with a compromised immune system. Nocardia israeli infections predominantly affect the lungs, leading to a condition known as pulmonary nocardiosis, which may present as pneumonia or abscess formation. However, it can also cause infections in other areas of the body, including skin, soft tissues, and the central nervous system.
Diagnosis of Nocardia israeli infections typically involves laboratory analysis of clinical samples, such as sputum, pus, or tissue samples. Microscopic examination of these samples reveals the characteristic filamentous structures of the bacteria. Additionally, special staining techniques, such as modified acid-fast stains, are often used to differentiate Nocardia species from other bacteria.
Treatment of Nocardia israeli infections usually involves a combination of antibiotics, such as sulfonamides, amikacin, and imipenem, administered over an extended period. Due to its slow growth rate and the potential for relapse, prolonged therapy is generally necessary.

Etymology of NOCARDIA ISRAELI
The word "Nocardia" comes from the name of Edmond Nocard, a French veterinarian and bacteriologist who discovered the bacteria in 1888. He named the genus after himself to honor his contributions to the field of bacteriology.
The term "israeli" in "Nocardia israeli" refers to the country Israel. This specific species was named after Israel because it was first isolated and described from patients in Israel. In the 1960s, Dr. Benyamin Jaffe and his colleagues identified the bacterium from several patients with a specific type of chronic skin infection, now known as "Nocardiosis". The naming of the species after Israel was intended to recognize the place of discovery.
