Risk of infection by the consumption of liver of chickens inoculated with low doses of Toxocara canis eggs

摘要: Abstract Experimental studies and registries of cases human toxocariasis have shown that the consumption raw or undercooked offal paratenic host Toxocara canis may pose a risk infection. Thus, we evaluated infection due to liver chickens inoculated with different doses embryonated T. eggs. Doses were 5–100 times smaller than ones previously employed in this type study. Groups five 5000 (control), 1000, 500, 300 50 eggs canis, at 72 h post-inoculation, each bird was consumed by BALB/c receptor mouse. Forty-eight hours after consumption, examined organs carcasses mice for larvae canis. All positive larvae, except group chicken This contained only one mouse, which larva lodged brain. In livers ≥300 eggs, concentration primarily lungs, characterizing initial phase We conclude poultry liver, under studied conditions, poses even low number infected
