NR-48882, Stage L3 Acanthocheilonema viteae, Infective Larvae, Harvested from Ornithodoros tartakovskyi (Live) is no longer available.

Acanthocheilonema viteae (A. viteae) (previously referred to as Dipetalonema viteae), strain FR3, was obtained from TRS Laboratories in Athens, Georgia, USA.

A. viteae does not contain the Wolbachia endosymbiont like most filarial nematodes that cause human disease. A. viteae is often used as the negative control for experiments investigating the bacterium.

NR-48882 consists of up to 1000 stage L3 A. viteae larvae harvested from Ornithodoros tartakovskyi. A. viteae are shipped in NI medium [1:1 mixture (v/v) of cell culture medium NCTC-135 and Iscove's modified Dulbecco's medium] supplemented with non-heat inactivated fetal bovine serum (final concentration 20%) and containing 100 units penicillin and 100 µg streptomycin per mL of fluid. Live A. viteae can be shipped in other media (i.e., RPMI-1640) per users' specific requests. If more material is required for your intended use, please contact BEI Customer Services at to request the additional material.

Note: Specific questions regarding handling of A. viteae can be sent to Dr. Shelly Michalski at
