Apparent dominance of the G1-G3 genetic cluster of Echinococcus granulosus strains in the central inland region of Portugal.
Infection by the larval stage of the cestode Echinococcus granulosus causes a disease known as cystic echinococcosis or hydatidosis, which is one of the most widespread zoonotic infections of veterinary and medical importance.
Wolbachia pipiens, an intracellular endosymbiont bacteria of filarial nematodes, has been implicated in the pathogenesis of filarial diseases, in particular in heavy Dirofilaria spp. infections. Antibiotic therapy (doxycycline) against Wolbachia has been proven to be suitable adjunct therapy, prior to adulticide treatment of canine dirofilariosis.
The role of the immunological background of mice in the genetic variability of Schistosoma mansoni as detected by random amplification of polymorphic DNA
Schistosomiasis is a parasitic disease caused by flatworms of the genus Schistosoma. Among the Schistosomaspecies known to infect humans, S. mansoni is the most frequent cause of intestinal schistosomiasis in sub-Saharan Africa and South America: the World Health Organization estimates that about 200,000 deaths per year result from schistosomiasis in sub-Saharan Africa alone. The Schistosoma life cycle requires two different hosts: a snail as intermediate host and a mammal as definitive host.
