What is Babesia species DNA by culture-enhanced PCR?
Babesia are intraerythrocytic protozoan parasites transmitted by ixodid ticks, primarily Ixodes scapularis in North America. The organisms invade and multiply within red blood cells, producing a haemolytic infection. Parasitaemia is often transient and low-grade in immunocompetent hosts but can be substantial in asplenic or immunocompromised patients. Standard PCR detection is limited by low or intermittent blood parasitaemia; culture-enhanced PCR addresses this by incubating whole blood to amplify parasite numbers before nucleic-acid extraction, increasing analytical sensitivity for early or subclinical infection.
