La leptospirosis en una enfermedad infecciosa, altamente contagiosa y ibicua, que afecta severamente la porcicultura, no obstante, su impacto económico no había sido estimado en los sistemas de producción del país. El conocimiento del impacto económico de una enfermedad permite estimar su importancia respecto de otras condiciones patológicas y escoger las mejores alternativas de prevención y control. El presente trabajo ...

A study was conducted in 36 farms of the Bogotá Savannah, Ubaté and Chiquinquirá Valleys and Tequendama Region (Cundinamarca), to determine via in vivo egg reduction count test (ERCT) antihelmintics resistance to bovine gastrointestinal nematodes. Resistance was determined in. 40 calves, three to 12 months of age, allotted to four groups of ten animals each one: 1) control (untreated); 2) albendazol 25% (5 mg/kg); ...

Regular diagnosis of leptospirosis is carried out by the microscopic agglutination test (MAI) which is defined as positive when readings are ≥ 1:100. Since this test only detects antibodies classified as M, it is considered ineffective for acceptable diagnosis in both: individuals or populations. Consequently, the level of infection in swine farms has been underestimated. A methodology was developed to improve reliability ...
