Concurrent Lyme disease and babesiosis: evidence for increased severity and duration of illness

Article Abstract:

Concurrent babesiosis can increase the severity of Lyme disease. Babesiosis is an infection caused by an organism called Babesia microti. It is often carried by the same ticks that carry the organism that causes Lyme disease, Borrelia burgdorferi. Researchers tested blood samples from 1,156 residents of Block Island, Rhode Island for the presence of antibodies to Babesia and Borrelia. Eighty-three percent had antibodies to Borrelia, 5% had antibodies to Babesia and 1% had antibodies to both. A total of 214 residents of Block Island and southeastern Connecticut had clinical symptoms of Lyme disease, 10 had been diagnosed with babesiosis and 26 were infected with both organisms. The 26 coinfected residents had a wider variety of symptoms than those with either organism alone. Half had at least one symptom that lasted 3 months or longer compared to 4% of those with Lyme disease alone. Seventy-three percent experienced fatigue one month or more compared to 23% of those with Lyme disease and 35% experienced fatigue six months or more compared to 3% of those with Lyme disease.

Persistent parasitemia after acute babesiosis

Article Abstract:

The parasite that causes babesiosis can linger in the body even after antibiotic treatment. Babesiosis is caused by the parasite Babesia microti, and the symptoms can resemble malaria. It is often considered a transient infection and is therefore not treated. In a study of 46 patients with babesiosis, parasite DNA persisted in the blood an average of 82 days in 24 patients who received no treatment. In these patients, symptoms lasted an average of 114 days if the parasite persisted for 3 or more months.
