Effect of vinegar or soy sauce at various concentrationons on the infectivity and reproductive capability of Trichinella spiralis muscle larvae

Objective To compare the effect of vinegar or soy sauce at various concentrations and different time on the infectivity and reproductive capability of Trichinella spiralis muscle larvae.Methods 84 Kunming mice were fed with muscle larvae in meat that soaked in vinegar(3.5 g/100 ml,4.5 g/100 ml,6 g/100 ml) or soy sauce (0.4 g/100 ml,0.7 g/100 ml,1.0 g/100 ml) and saline,with different concentrations and for different time(3,6,12 h).The infected mice were killed after 7 days and 30 days and the intestinal adult worms,muscle larvae and reproductive capacity index (RCI) were observed and counted.Results The intestinal adult worms were 150,110,80,respectively and RCIs were 85.87,52.00,29.33respectively in mice fed with muscle larvae treated by vinegar(3.5 g/100 ml) for 3,6,12 h; the intestinal adult worms were 120,90,50,respectively and RCIs were 72.53,52.53,17.33 respectively in mice fed with muscle larvae treated by vinegar(4.5 g/100 ml) for 3,6,12 h ; the intestinal adult worms were 60,40,11,respectively and RCIs were 52.00,12.00,8.00,respectively in mice fed with muscle larvae treated by vinegar(6 g/100 ml) for 3,6,12 h ; the intestinal adult worms were 190,140,60,respectively and RCIs were 65.73,45.60,24.27,respectively in mice fed with muscle larvae treated by soy sauce (0.4 g/100 ml) for 3,6,12 h the intestinal adult worms were 120,80,20,respectively and RCIs were 46.67,38.27,21.33,respectively in mice fed with muscle larvae treated by soy sauce (0.7 g/100 ml) for 3,6,12 h; the intestinal adult worms were 45,30,15,respectively and RCIs were 43.20,18.33,9.00,respectively in mice fed with muscle larvae treated by soy sauce ( 1.0 g/100 ml) for 3,6,12 h,lower than that in saline control mice( the intestinal adult worms were 200,180,120,respectively and RCIs were 96.00,60.80,48.06,respectively).The effect was different when soaked in vinegar or soy sauce at various concentrations on the infectivity and reproductive capability of Trichinella spiralis muscle larvae by variance analysis.The infectivity capability of Trichinella spiralis muscle larvae still existed after muscle larvae treated by vinegar(3.5 g/100 ml) for 3,6 h,vinegar(4.5 g/100 ml) for6h,soy sauce (0.4 g/100 ml ) for 6 h,the reproductive capability of adult was not affected after.muscle larvae treated by vinegar( 3.5 g/100 ml) for 3,6,12 h,vinegar(4.5 g/100 ml) for 3 h,soy sauce (0.4 g/100 ml) for 3,6 h.Conclusion The infectivity and reproductive capability of Trichinella spiralis muscle larvae were decreased after the treatment of vinegar or soy sauce at certain concentrations for certaion time.
