The rock dove Columba livia is an exotic and feral bird that has been described as carrying various agents potentially pathogenic to man and other birds, including bacteria such as Salmonella spp. and E. coli, however, there are few studies regarding infectious disease agents carried by the species in our country. The objective of the study was to determine the enterobacterias present in this free-living bird resident in the City of Lima. During the months of June and July of 2014, 27 adult individuals of C. livia were captured in two zoos located in the districts of Chorrillos and San Juan de Miraflores. A cloacal swab was made to each bird and transported in the Cary Blair transport medium at 4 °C to a private laboratory. In the laboratory, samples were plated on McConkey agar and SS agar, and then proceeded to the identification using biochemical tests (TSI, LIA, Indol, SIM, Citrate, Methyl Red and Voges Proskauer). A total of 35 bacterial colonies were isolated 85.19 % (23/27) from the samples: 62.96 % (17/27) Escherichia coli, 11.11 % (3/27) Enterobacter aerogenes, 11.11 % (3/27) Klebsiella sp., 11.11 % (3/27) Proteus vulgaris, 7.41 % (2/27) Salmonella pullorum, 14.29 % (14/27) Shiguella sp., 11.11 % (3 / 27) Staphylococcus aureus and 3.70 % (1/27) Staphylococcus sp. Here, we report a high frequency of enterobacteria of interest in public health, evidencing the importance of considering rock dove as a reservoir for zoonotic bacteria.
En respuesta al reto educativo emergente debido a la pandemia por la Covid-19 y para mitigar algunas debilidades evidenciadas en las pruebas Saber componente aleatorio) para grado tercero primaria (ICFES, 2018) y en el estudio SERCE (Ruiz López, 2015) realizado por la UNESCO, la presente investigación describe y analiza la experiencia de implementar el uso de recursos virtuales en el proceso de enseñanza-aprendizaje de la probabilidad intuitiva en estudiantes de grado tercero de primaria de una escuela rural durante el periodo de confinamiento debido a la pandemia por la Covid-19 en Colombia (Wikipedia, 2021) El estudio se enmarca dentro del paradigma cualitativo de tipo descriptivo e implementa la Investigación Acción-Participativa (IAP). Respecto a la metodología investigativa, una entrevista abierta de entrada permitió describir los pre-saberes de los estudiantes en relación con la probabilidad intuitiva, enseguida, se diseñó e implementó una secuencia didáctica (Cuevas, 2020) y, finalmente, una entrevista abierta de salida permitió evaluar el impacto y la experiencia vivida en la etapa anterior. En el análisis de resultados y apelando a la experiencia vivida en la emergencia sanitaria por la Covid-19, se establecen sugerencias acerca del uso de estrategias virtuales para la enseñanza de la probabilidad intuitiva en edades tempranas y durante situaciones de emergencia en zonas rurales. En este contexto, los resultados investigativos evidencian una incidencia positiva en la formación de capacidades para la toma de decisiones en situaciones cotidianas que involucran cierto grado de incertidumbre.
