A study was followed with the aim to compare the efficacy of levamisol using two doses against gastrointestinal and lung worm nematodes in bovines. Fifteen naturally infected calves were divided in three groups of five animals each. The first group was treated with 3.18 mg/kg, the second one with 2.70 mg/kg and the third one, was the control. The animals were slaughtered seven and eight days post-treatment. Results indicate that the efficacy for 3.18 mg/kg and 2.70 mg/kg was: in the abomasum against Haemonchus spp 100 percent and 85.7 percent, Cooparia spp 100 percent and 99.36 percent and Trichostronglylus axe, 100 percent and 100 percent; in the small intestine against cooparia spp 100 percent and 90.85 percent; in the large intestine against Oesophagostomum spp 100 percent and 100 percent, Trichuris 100 percent and Dictylocaulus viviparus 99.5 percent and 99.16 percent respectively. With the aim to determine the yearly frequency of bovine liver flukes, in 14 states of Mexico during the period 1979-1987, a study was followed. In this period 5,797,466 bovines were slaughtered. The number of confiscated livers with Fasciola spp was 424,000 which is equivalent to 7.31 percent according to the total number of animals slaughtered. The annual confiscation percentage is as follows: Tabasco with 31 percent, Guanajuato with 12.08 percent and Durango with 5.07 percent. The states with less liver confiscations were: Nuevo Leon (0.80 percent), Guerrero (0.70 percent), Baja California (0.40 percent), Chiapas (0.37 percent) and Sonora (0.23 percent).
