Human toxocariasis: a report of nine cases
2008
Aim: Human toxocariasis is caused by infection with the larval stage of nematode parasites of dogs and cats, Toxocara canis or Toxocara cati. These helminths are not able to complete their life cycle in undefinitive hosts and so undergo aberrant migrations in the tissues causing a wide spectrum of signs and symptoms. Eosinophilia is often severe and sometimes represents the only sign of infection, except in ocular and neurological forms. Methods: We describe the clinical features of nine children affected by toxocariasis admitted to our Infectious Diseases department from 2004 to 2006. Results: Fever and hepatomegaly were the most common clinical findings. In two cases eosinophilia was not …
Helminth parasites of the wolfCanis lupusfrom Latvia
2009
AbstractThirty-four wolves were collected between 2003 and 2008 from throughout Latvia and examined for helminths. A total of 17 helminth species were recorded: the trematodeAlaria alata(85.3%); the cestodesDiphyllobothrium latum(2.9%),Echinococcus granulosus(2.9%),Echinococcus multilocularis(5.9%),Mesocestoides lineatus(5.9%),Taenia crassiceps(8.8%),Taenia hydatigena(41.2%),Taenia (ovis) krabbei(8.8%),Taenia multiceps(47.1%),Taenia pisiformis(20.6%),Taenia polyacantha(11.8%),Taeniaspp. (8.8%); and the nematodesAncylostoma caninum(2.9%),Crenosoma vulpis(9.1%),Eucoleus aerophilus(36.4%),Pearsonema plica(41.4%),Trichinellaspp. (69.7%),Toxocara canis(5.8%), andUncinaria stenocephala(41.2%).Ala…
Toxocara canis infection induces antigen-specific IL-10 and IFNγ production in pregnant dogs and their puppies
2005
Toxocara canis (T. canis) is originally a parasite of canine bitches and their pups. The pathogenicity of T. canis infection is enhanced during pregnancy and puppyhood. The aim of this study was to investigate if modification of IFNgamma and IL-10 secretion occurs during infection in pregnant dogs and puppies. Analysis of cytokines secreted could let us hypothesize a role for IL-10 and/or IFNgamma in T. canis infection. We tested T. canis-specific production of IFNgamma and IL-10 by lymphocytes of pregnant dogs and their puppies after in vitro re-exposure to purified excretory/secretory antigen (ESAg) from T. canis. Blood mononuclear cells (BMC) isolated from pregnant dogs and their puppies…
