Epidemiological investigation of the first human brucellosis case in Spain due to Brucella suis biovar 1 strain 1330 / Investigación epidemiológica del primer caso de brucelosis humana en España por Brucella suis biovariedad 1 cepa 1330

INTRODUCTION: No cases of human brucellosis caused by Brucella suis has been reported in Spain. METHODS: This study involved interviews with the case and his co-workers, inspection of their workplace, checking infection control measures, and typing the Brucella strain isolated in the blood culture. RESULTS: Brucella suis biovar 1 strain 1330 was isolated from a patient who worked in a waste treatment plant. Food borne transmission, contact with animals, and risk jobs were ruled out. An accidental inoculation with a contaminated needle from a research laboratory waste container was identified as the most probable mode of transmission. CONCLUSION: There should be controls to ensure that waste containers are sealed

INTRODUCCIÓN: En España no se habían comunicado casos humanos de brucelosis por Brucella suis anteriores a este. MÉTODOS: La investigación incluyó entrevistas con el caso y sus compañeros de trabajo, inspección del lugar de trabajo, comprobación de las medidas de control de la infección, y tipificación de la cepa de Brucella aislada en el hemocultivo. RESULTADOS: Se aisló Brucella suis biovariedad 1 cepa 1330 en un paciente que trabajaba en una empresa de tratamiento de residuos. Se descartó la fuente alimentaria, el contacto con animales y trabajos de riesgo. Un pinchazo accidental con una aguja contaminada de un contenedor procedente de un laboratorio de investigación fue la forma de transmisión más probable. CONCLUSIÓN: Se deben realizar controles para asegurar que los contenedores de residuos están sellados
