Brucelosis en alpacas (Lama pacos) en las comunidades del cantón Ulla Ulla, provincia Franz Tamayo del departamento de La Paz
Abstract
This investigation was performed in the Altiplano Altoandino sub-humid region in the Ulla Ulla district, Pelechuco township, Franz Tomayo province, department of La Paz, Bolivia. The objective of this study was to quantify and compare the presence of Brucellosis in male and female alpacas (Lama pacos) at ages 2, 3, 4, 5, 6, and 7 years. Blood samples were taken from the jugular vein of 500 alpacas from the Hichucollo, Huacuchani, Ucha Ucha, and Ulla Ulla communities. The serum from each sample was separated and a serological diagnosis was performed by rapid agglutination with Rose Bengal chemical stain. In the Ulla Ulla district, 11.0% of alpacas were suspected of being infected. Of that 11.0%, 9.6% represented female alpacas while the remaining 1.4% represented male alpacas. By community, the overall results were 0.6%, 0.2%, 7.4%, and 2.8% for Hichucollo, Huacuchani, Ucha Ucha, and Ulla Ulla respectively. With regards to gender in each community, 1.4%, 1.6%, 13.3%, and 11.1% of female alpacas and 2.7%, 0.0%, 1.2%, and 1.9 % of male alpacas were suspected of being infected in Hichucollo, Huacuchani, Ucha Ucha, and Ulla Ulla, respectively. According to age, 0.8%, 2.6%, 3.8%, 2.0%, 11.8%, and 0.0% were suspected of Brucellosis in alpacas 2, 3, 4, 5, 6, and 7 years old, respectively in the Ulla Ulla district. The analysis of variance among the results does not present significant differences (p ≥ 0.05), failing to reject the given hypothesis. The final prevalence point found in the Ulla Ulla district was 11.0%. It was concluded that the prevalence of suspected cases of Brucellosis in alpacas is a consequence of the antigenic characteristics of each biotype. Furthermore, the results affirm that the poor management of livestock and livestock health lead to significant problems with alpaca health. It is therefore necessary to implement control strategies as well as disease monitoring in communities by following a detailed program of diagnostic tests for Brucellosis. Also, non-infected flocks must be protected against infection.
Abstract (Spanish)
El presente trabajo de investigación se realizó en el Altiplano altoandino subhúmedo del cantón Ulla Ulla, municipio de Pelechuco, de la provincia Franz Tamayo del departamento de La Paz. El objetivo del trabajo fue cuantificar y comparar la presencia de brucelosis en alpacas (Lama pacos) machos y hembras de 2, 3, 4, 5, 6, y 7 años de edad. Las muestras de sangre se tomaron de la vena yugular de 500 alpacas de las comunidades Hichucollo, Huacuchani, Ucha Ucha y Ulla Ulla. Se separaron lo sueros y se realizó el diagnostico serológico por aglutinación rápida con rosa de bengala. Los resultados en el cantón Ulla Ulla fueron: 11.0% sospechosos de estar infectados y por comunidad: 0.6%, 0.2%, 7.4% y 2.8% en Hichucollo, Huacuchani, Ucha Ucha y Ulla Ulla respectivamente. El 9.6% de alpacas hembras y el 1.4% de alpacas machos resultaron sospechosos en el cantón Ulla Ulla; y por comunidad: 1.4%, 1.6%, 13.3% y 11.1% en alpacas hembras y 2.7%, 0.0%, 1.2% y 1.9% en alpacas machos en Hichucollo, Huacuchani, Ucha Ucha y Ulla Ulla respectivamente. Los reactores sospechosos de brucelosis según edad fueron 0.8%, 2.6%, 3.8%, 2.0%, 11.8% y 0.0% en las alpacas de 2, 3, 4, 5, 6, y 7 años de edad respectivamente en el cantón Ulla Ulla. Al análisis de varianza los resultados no presentan diferencias significativas (p≥0.05), aceptándose la hipótesis planteada. La prevalencia puntual final hallada en el cantón Ulla Ulla fue de 11.0%. Se concluyó que la prevalencia de casos sospechosos de brucelosis en alpacas es consecuencia de las características antigénicas de cada biotipo y según este resultado se afirma que el deficiente manejo sanitario y manejo de ganado en general provocan problemas como este de tipo zoosanitario, por tanto, es necesario implementar estrategias de control y vigilancia de la enfermedad en las comunidades siguiendo un programa real a través de pruebas diagnósticas de brucelosis y los rebaños no infectados deben ser protegidos contra la infección.
