To estbalish the presence of B. suis antibodies in domestic and street dogs in Villavicencio, Meta, Colombia. Materials and methods. 201 dog sera samples were analized by rapid plate agglutination test with mucoid (M-) antigen. Isolation by haemoculture in Brucella selective medium (Oxoid®) was attempted in two seropositive animals. Histopathology of the testicle, spleen and liver were carried out on a seropositive animal having bacterial growth with morphological characteristics suggestive of B. suis. Results. General seropositivity was 1.49% and corresponded to three male dogs, two of them presented clinical signs of unilateral epididymitis and orchitis. Culture and histopathology were unable to diagnosis B. suis. Conclusions. Seropositivity was low and suggested that the population being studied had not been in contact with the bacteria. The presence of reactors could have been associated with false positives. The failure to isolate bacteria did not indicate that the disease does not exist, therefore, new studies are needed.

In the exposed infants we found retardation of general and brain growth; neurological involvement evidenced by irritability, nausea and weak cry; also by depression of the sucking, stepping response, Landau and placing reflexes (in the latter three, duration of the depression but not its frequency was significantly higher in the exposed infants); bone changes consisting of maturation delay and metaphyseal dense streaks attributable to lead deposition. Despite significantly higher blood-lead levels in the exposed mothers and infants no evidence could be found of liver, kidney or hematological alterations; lead-poisoning signs were absent. Based on these findings we conclude that fetal exposure to basuco is associated with high blood lead. Levels, generalized growth retardation which includes the brain, bone lesions and a clear-cut but self-limited neurological syndrome Con la metodología de cohortes se estudiaron 23 parejas madre-hijo consumidoras de basuco, (cohorte expuesta), y 20 parejas no consumidoras que sirvieron como controles. Se comparó en los niños la frecuencia de retardo ponderal, alteraciones neurológicas, alteraciones fisiológicas en el hígado, los riñones y la sangre y signos clínicos, hematológicos y óseos de plumbismo; se determinaron los niveles de plomo en la sangre materna y en la del cordón umbilical. Se encontró que los niños expuestos presentaban retardo generalizado del crecimiento, Incluyendo el tamaño del cerebro, y un cuadro neurológico caracterizado por: llanto deprimido, Irritabilidad, náuseas y disminución de los reflejos de succión, marcha automática, enderezamiento y del alpinista. Con respecto a los tres últimos, aunque su frecuencia absoluta no fue significativamente superior, sí lo fue la duración promedio de la depresión. Las concentraciones sanguíneas de plomo en las parejas expuestas fueron: 15.2 :t 7.6 ug/dl en los niños y 14.2 :t 5.8 ug/dl en las madres. En los controles se encontraron 6.8 :t 5.0 y 8.4 :t 4.5 ug/dl respectivamente. Se detectaron alteraciones óseas en 15 niños expuestos (75%), a saber: en 14 retardo de la maduración relacionado, posiblemente, con el bajo peso y en 6 (30%), lesiones radiodensas metafisiarias longitudinales o transversales atribuibles al depósito de plomo. No se detectaron signos clínicos de plumbismo ni alteraciones fisiológicas en los riñones, el hígado o la sangre durante el tiempo del estudio. Los anteriores hallazgos permiten concluir que la exposición del feto al basuco consumido por la madre, se asocia con retardo del crecimiento general y cerebral, así como con manifestaciones neurológicas definidas. Entre las alteraciones qulmicas se destaca la elevada concentración de plomo en la sangre de las madres e hijos expuestos y su posible relación con las alteraciones óseas encontradas en los niños.
