Muscular strength decrease in Rattus norvegicus experimentally infected by Toxocara canis.
The muscular strength of experimental infected Rattus norvegicus with 3rd. stage Toxocara canis larvae was investigated. Fifty Wistar rats, divided in three groups (G1-20 rats infected by 300 eggs of T. canis; G2-20 rats infected by 2,000 eggs of T. canis and G3-10 rats without infection) had been used. Ten and 30 days after infection the muscular strength in the fore-feet of the rats was checked; at the same time, the body weight was determined. No significative differences in the body weight were noted among the infected and control rats in both occasions. Otherwise, an impairment on the muscular strength was observed in rats infected with T. canis 30 days after inoculation.
