Babesia research: biology, diagnosis, treatment, persistence, resistance and experimental therapies.
This library prioritizes peer-reviewed papers, major reviews, CDC guidance and IDSA recommendations. Each source is labeled by the question it helps answer so you can move from a claim to the underlying evidence.

Start here for the big picture
High-level review of parasite biology, transmission, epidemiology, clinical manifestations, immunity, diagnosis and treatment.
Read the review →Detailed review with extensive discussion of human disease and pathogenesis.
Read free full text →Evidence-graded recommendations for smear/PCR confirmation, antibody interpretation, treatment, exchange transfusion and monitoring.
Read the guideline →Current U.S. public-health summary of standard therapy and management considerations.
Read CDC guidance →Studies that explain why testing can be confusing
Longitudinal study showing that low-level parasitemia can persist for months or years, especially when untreated, and that drug therapy shortens—but does not always immediately eliminate—detectable parasitemia.
Read the study →Explains why PCR is more sensitive than smear at low parasite burdens, why hundreds of smear fields may need review, and why one positive antibody test cannot establish active infection.
Read the full guideline paper →Standard treatment, relapse and resistance
Randomized trial showing similar efficacy to clindamycin/quinine in uncomplicated disease with substantially fewer reported adverse effects.
Read the trial →Case-control study identifying B-cell dysfunction, rituximab exposure and splenectomy as major features of persistent/relapsing cases.
Read the study →Molecular evidence linking treatment failure with mutations in cytochrome b and ribosomal protein L4.
Read the paper →Five-patient case series examining tafenoquine-containing regimens in highly immunocompromised people with difficult relapsing disease.
Read the case series →Parasite biology and drug susceptibility
Established a human-red-cell culture system and reported relatively low susceptibility of B. duncani to several drugs commonly used for babesiosis.
Read the paper →Experimental work investigating mitochondrial electron transport as a target and newer endochin-like quinolone compounds.
Read the paper →Demonstrates antioxidant/redox machinery used by the parasite during the erythrocytic stage.
Open PubMed →Cryptolepis, artemisinin and ozone-related mechanisms
In-vitro testing of Cryptolepis sanguinolenta, Artemisia annua, Scutellaria baicalensis, Japanese knotweed and related compounds.
Read the full paper →In-vitro activity across several Babesia species plus a B. microti mouse model.
Read the PLOS paper →Important counterevidence showing lack of benefit under that experimental protocol.
Read the paper →Mechanistic human-cell study showing activation of antioxidant-response pathways after exposure to ozonated serum; not a Babesia treatment trial.
Open PubMed →Experimental protozoal inactivation study in water. Relevant to ozone's chemical reactivity, but not evidence that medical ozone treats intraerythrocytic Babesia in humans.

These are the Amazon-linked products connected to what I personally used. I am sharing them as part of my experience, not as proven babesiosis treatments or dosing recommendations. Browse all recommended products →
What I personally usedCryptolepis sanguinolenta
A commercial Cryptolepis product. Laboratory and animal evidence discussed here should not be confused with proven human treatment efficacy.

What I personally usedArtemisinin
A commercial Artemisinin product. Experimental evidence discussed here is mixed and does not establish commercial supplements as proven human babesiosis treatment.

Cryptolepis and artemisinin are the two products I personally used during my Babesia experience. I am sharing what I used, not prescribing a treatment. The other items are practical support products people may find useful while keeping track of medications, supplements, and hydration.

Practical support
Hydration / electrolyte packets
Convenient hydration support for people who want an easy electrolyte option. This is not a Babesia treatment.
