Since the 1990s, the major approach to hookworm control has been morbidity reduction in school-aged children by periodic deworming with benzimidazoles. Now, efforts are underway to determine the feasibility of integrating deworming with control programs that target other neglected tropical diseases. However, the sustainability of benzimidazole deworming for hookworm is of concern because of the variable efficacy of mebendazole, high rates of post-treatment reinfection and possible development of drug resistance. This requires parallel efforts to develop new and complementary hookworm control tools, such as new anthelmintic drugs (e.g. tribendimidine) and a recombinant hookworm vaccine. It is hoped that, ultimately, anthelmintic vaccination will be linked to deworming as part of an expanded control package.
Although Uncinaria stenocephala is the most frequent hookworm in the intestine of dogs from Northern, Central and Southern Europe, little is known about its host-parasite relationship. Three groups of sera from dogs (Group 1: dogs naturally infected only by U. stenocephala; Group 2: helminth-free dogs at necropsy, and Group 3: dogs parasitized by other helminths) were analyzed by ELISA using U. stenocephala antigens from adult worms (somatic and excretory-secretory antigens) and from L3 larvae (somatic antigens). All three sources of antigens were found to be suitable for immunodiagnosis of canine uncinariosis with up to 90% efficacy. However, an analysis to assess the diagnostic value of the different antigens demonstrated that the adult excretory-secretory antigens had a higher diagnostic efficacy (96.7%), indicating that this is the best antigen source for the diagnosis of Uncinaria infection.
The anthelmintic activity of the drupe extracts of Melia azedarach L. (Meliaceae) growing in Argentina was tested against tapeworms, hookworms, nodular worms and earthworms, and was shown to be better than the standards piperazine phosphate and hexylresorcinol against tapeworms and hookworms, respectively.
