| Abstract: | The effects of anesthetics on the peripheral blood microfilaremia of Brugia malayi in Meriones unguiculatus were investigated. Microfilaremias were assessed by orbital puncture prior to and following the use, either individually or in tandem, of ether, Rompun(R), Ketaset(R), and sodium pentobarbital. Results indicate that the peripheral microfilaremia varied dramatically, depending on the anesthetic administered. Although microfilaremias were not affected by an initial ether exposure, counts of microfilariae increased significantly when jirds received Rompun and Ketaset, or Ketaset alone. Administration of sodium pentobarbital did not increase the number of microfilariae observed in the peripheral blood. The mode of action differs between these drugs and is likely responsible for the different effects observed. Consequently, studies involving vector-parasite interactions should take precautions to prevent parasite-induced vector mortality due to the ingestion of large numbers of microfilariae induced in the peripheral bloodstream by certain anesthetics. |
