Brucella species cause a high burden of disease globally, infecting both humans and animals; however, One Health has been under-appreciated in Colombia. This study aimed to determine the seroprevalence of Brucella spp. in two remote indigenous communities from the Sierra Nevada de Santa Marta, Colombia. These communities live in close contact with their livestock, indicating a potential susceptibility to zoonotic pathogens. The livestock routinely kept by these communities include cattle, small ruminants and pigs, the known hosts of human pathogenic Brucella spp.. A low level of exposure to Brucella spp. was documented, with only one positive participant among 539 participants (0.2%; 95% CI 0.0 – 1.0). Nevertheless, due to the high risk that zoonoses pose, we recommend discussions with the community for the potential establishment of One Health surveillance studies for the early detection and prevention of future zoonotic disease threats.

Se realizaron estudios para evaluar el potencial antimicrobiano de la mucosidad de la piel recolectada del pulpo común Octopus bimaculatus contra ciertas cepas patógenas para crustáceos, moluscos, peces y bovinos; Escherichia coli, Staphylococcus aureus, Vibrio harveyi, Vibrio parahaemolyticus y Staphylococcus pasteuri. Las actividades antimicrobianas se midieron en términos de halos de inhibición en mm y se compararon con dos antibióticos amikacina y cloranfenicol. También se estimó la cantidad de proteína en el moco de pulpo en mg ml-1. Se observaron halos de inhibición en las tres concentraciones de moco contra los patógenos seleccionados, con la excepción de la cepa V. parahaemolyticus, que no mostró inhibición en la concentración mínima. Además, en la concentración más alta, la cepa V. parahaemolyticus fue la menos inhibida, con un diámetro de 3.9 ± 0.2 mm. Los dos antibióticos inhibieron todas las cepas, siendo la cepa E. coli la más inhibida. Por lo tanto, estos resultados han revelado que el moco obtenido de la piel de pulpo muestra actividad antibacteriana que puede desempeñar un papel importante en la protección de los organismos acuáticos o terrestres contra los patógenos y, por lo tanto, se podría usar el moco obtenido de la piel del pulpo como alternativa a los antimicrobiano en animales de granjas acuícolas y terrestres.

Control of Salmonella in pig/pork production is important to protect public health because pork is one of the main sources of human infection. Moreover, antimicrobial use in pig farms should be kept low to minimize development and transmission of antimicrobial resistance. This pilot study evaluated the productivity and Salmonella seroprevalence in pigs administered organic acids (OA) compared to pigs given growth promoters in one farm in Antioquia, Colombia. Two groups each consisting of 60 pigs of 6-weeks of age were studied for 4 months. One group was provided feed and water with OA (Selko pH® and Selacid®), whereas the other group (control) received antimicrobial growth promoters according to routine feeding practices (tylosin and zinc bacitracin). Blood samples were taken three times (T1–T3) and pigs were weighted five times to calculate daily weight gain (DWG) and feed conversion ratio (FCR). Initially when the pigs were 6 weeks old (T1), the Salmonella seroprevalence was 1.7% in both groups. When the pigs were 11 weeks old (T2), the seroprevalence was significantly lower in pigs provided OA compared to the control group (19 vs. 47%, P < 0.001), whereas when the pigs were 23 weeks old (T3), the seroprevalence did not differ between the groups (62 vs. 77%; P = 0.075). The cumulative DWG was significantly higher in the intervention group than in the control group (713 vs. 667 g/day; P < 0.001). The cumulative FCR did not differ between groups (2.80 vs. 2.77; P = 0.144). The pilot study indicates that cleaning the water pipes and administrating OA improve productivity in pigs and delay exposure to Salmonella spp. when compared with growth promoters. Thus, OA could replace antimicrobial growth promoters and reduce antimicrobial use and resistance. However, the study should be repeated before firmer conclusions can be drawn.
