The COVID-19 pandemic is not over, the Coronavirus Disease 19 Pandemic due to the SARS-CoV-2 virus is spreading very quickly in almost every country in the world because of its human-to-human nature. The COVID-19 pandemic in Indonesia was detected in Depok, West Java on March 2, 2020. To deal with this, the government must decide on an efficient policy by observing the atmosphere and situation in each region. The way is through determining the risk status of COVID-19 transmission in an area in order to break the chain of transmission of COVID-19. In Indonesia, it is up to each local government to determine the risk status of Covid-19 transmission at the regional level. This has led to subjective evaluations by local leaders and introduced many unclear definitions and boundaries when determining the risk status of COVID-19 transmission. This is the reason behind this research, where the Tsukamoto Algorithm mathematical calculation form is based on the official variables and regulations in the area concerned in determining the risk status of COVID-19 transmission. The data used is the daily data for COVID-19 districts or cities in East Java. The data used are 38 district or city data groups consisting of 4 variables. The input variables are COVID-19 positive cases, Supek cases, and Probabe cases, and each variable is defined as 3 fuzzy sets, namely Low, Medium, and High. The output variables are defined in 4 fuzzy sets regarding the Risk Status for COVID-19 Transmission, such as the East Java Government regulations, namely the status of green, yellow, orange, and red. All variables use membership function of triangular curve representation. How to analyze data using the SPK-COVID application using the Codeigniter Framework. The success of the estimation form of the percentage of conformity status generated by comparing the results of the Tsukamoto Algorithm analysis with real COVID-19 transmission risk status data. After doing 4 repetitions of the analysis, in which each analysis tries to change the area in the fuzzy set, we get a structure with a percentage of status conformity that is usually 95.51%, on data from 38 districts or cities in East Java.

El taller 2020 (virtual) tuvo como objetivo que productores, que habían participado en talleres anteriores del grupo (presenciales), afiancen los conocimientos a través de la práctica en establecimientos propios. Para esto cada productor trabajó en alguno de los siguientes ejes temáticos: 1) siembra de pasturas y verdeos; 2) manejo y mejoramiento de pastizales naturales y 3) diseño de circuitos forrajeros. Todos los productores abordaron el cálculo de la producción de carne para sus establecimientos, independientemente del eje temático elegido. Durante 6 meses, se realizó un trabajo conjunto entre productores, docentes y un joven profesional agrónomo. Se trabajó individualmente sobre la aplicación del tema elegido y, al finalizar el trabajo individual, se llevó adelante una jornada conjunta de intercambio donde cada productor presentó a sus pares en forma virtual el trabajo realizado, sus dificultades y resultados obtenidos. El taller se evaluó mediante encuestas a los participantes y la elaboración de un análisis FODA. Los resultados mostraron que el taller permitió a los productores practicar los conceptos presentados previamente e incorporarlos al manejo de sus establecimientos. A su vez, permitió consolidar un método efectivo y replicable para la generación y transferencia de tecnologías de procesos desde la FAUBA hacia el sector productivo.

Los microorganismos ácido lácticos poseen un efecto benéfico en el engorde de los cuyes, al mejorar la degradación de la materia orgánica y prevenir la salmonelosis. El objetivo fue evaluar los microrganismos acido lácticos y levaduras como suplemento en las raciones para el engorde de cuyes (Cavia porcellus) en Ayacucho. Se activaron las bacterias en caldo lactosado a 37°C por 48 horas en anaerobiosis, a través de diluciones consecutivas se sembró en agar Rogosa sharpe incubándose a 37°C por 24 a 48 horas para recuento del número de células vivas/ml. Se utilizaron 20 gazapos machos destetados con tamaño y peso homogéneos. Se tuvo 5 tratamientos suplementando con bacterias ácido lácticas al alimento balanceado: T1 (Lactobacillus acidophilus), T2 (Lactobacillus casei), T3 (Lactobacillus acidophilus y Lactobacillus casei) y T5 (testigo), brindándose a libre discreción y alfalfa al 10% de su peso vivo más agua. Como unidad experimental se planteó bajo el diseño completamente randomizado con 5 tratamientos, 2 repeticiones y 2 cuyes. Los resultados mostraron que para el peso vivo y la ganancia de peso resultaron no significativos (p<0.05) y para el consumo de alimento y la conversión alimenticia fueron significativas. Por la prueba de Tukey resultó que los tratamientos con la combinación T3 Lactobacillus acidophilus + Lactobacillus casei y T2 Lactobacillus casei fueron mejores lográndose peso comercial para el mercado en ocho semanas de tratamiento, además mejores rendimientos de carcasa. Con ello se puede intuir que los microorganismos influyen positivamente en el desarrollo de los cuyes.

Con el objetivo de asociar el tamaño de los ornamentos sexuales con caracteres reproductivos y productivos en gallinas del cruzamiento de tres vías Campero Casilda se calcularon, en 97 aves de 30 semanas, los índices de cresta [IC: longitud x alto] y barbilla [IB: longitud x ancho]. Los datos individuales se graficaron en un sistema de ejes cartesianos (X: IC; Y: IB) el que se dividió en cuatro cuadrantes mediante dos rectas que intersectan a cada eje a nivel de los valores medios. Se identificaron las aves con valores extremos de ambos índices [Cuadrante I (CI): > IC > IB y Cuadrante III (CIII): < IC < IB] y, para cada una de ellas, se registraron los caracteres productivos a la madurez sexual, cuatro indicadores de desarrollo óseo a las 30 y 71 semanas, los patrones dinámicos del peso corporal y el peso del huevo y la relación de conversión en huevos en la primera parte del ciclo de postura. Las aves con mayor desarrollo de los ornamentos sexuales (a) fueron más precoces y comenzaron la postura con huevos de menor peso, pero con similar regularidad y uniformidad, presentando (b) mayor longitud del tarso y del fémur en ambas edades, mayor diámetro del tarso a las 30 semanas y mayor longitud de la tibia a las 71 semanas de edad (c) mayor tasa de crecimiento exponencial entre la sexta y la vigésima semana pero similar patrón de crecimiento global, (d) menor peso asintótico del huevo, menor tasa de maduración para el carácter y menor peso teórico del primer huevo y (e) mayor número de huevos de menor peso y similar relación de conversión entre las 26 y 35 semanas. La combinación del tamaño de los ornamentos sexuales se presenta como una alternativa para la selección temprana de los reproductores.

El objetivo de trabajo fue caracterizar el ciclo del epitelio vaginal de ovejas de raza Santa Inês, mediante estudio citológico. Se tomaron muestras de la mucosa vaginal a 10 borregas sexualmente maduras, desde el primer día de celo y por 18 días. Las muestras se colorearon con Papanicolaou y se observaron en microscopio óptico. Se reconocieron células parabasales, intermedias profundas, intermedias superficiales y superficiales. Las células parabasales presentaron forma redondeada, citoplasma escaso y núcleo grande, fueron escasas. Las intermedias profundas de bordes redondeados, citoplasma más abundante y núcleo menor. Se observaron en mayor cantidad que las parabasales. Las intermedias superficiales fueron las más abundantes en todo el estudio y las de mayor diámetro. Presentaron forma poligonal y núcleo más pequeño. La identificación de dos tipos de célula intermedia, coincide con trabajos en perras, vacas y alpacas, en tanto otros trabajos describen un solo tipo. Las células superficiales se dividieron en dos subtipos, el A, con forma poligonal y núcleo picnótico y el B, con citoplasma más pequeño e intensamente acidófilo y núcleo picnótico. Este último no se encontró hasta el momento en otros trabajos con ovejas. Las modificaciones de los tipos celulares no reflejaron de manera precisa la fase del ciclo estral.

La infección por Trypanosoma cruzi, agente etiológico de la enfermedad de Chagas, es una zoonosis compleja. En el ciclo biológico de T. cruzi intervienen mamíferos como el hombre y animales domésticos (ciclo doméstico y peridoméstico) o silvestres como roedores y carnívoros (ciclo selvático). Desde el punto de vista epidemiológico el perro es el reservorio más importante. El objetivo fue diagnosticar la infección por T. cruzi en caninos residentes del Valle de Acambuco, Provincia de Salta, Argentina. El estudio se llevó a cabo en la localidad de Acambuco, Salta, Argentina. Se analizaron 24 caninos domésticos por métodos serológicos: HAI y ELISA, parasitológicos: hemocultivos y moleculares: PCR. Resultados: tres muestras caninas fueron positivas por ambas pruebas serológicas y una de éstas por PCR. Ninguna de éstas resultaron positivas por hemocultivo. En conclusión, los resultados demostraron que en la localidad de Acambuco hay presencia de anticuerpos contra T. cruzi en los perros, indicando infección parasitaria en un pasado reciente.

La ultrasonografía, en medicina equina, es una técnica fundamental para el diagnóstico de las claudicaciones y en la evaluación de la disminución del rendimiento deportivo. A pesar del gran desarrollo del Modo B es escasa la utilización del Doppler Color y específicamente del Doppler de Poder o power angio en la evaluación de las afecciones músculo-esqueléticas en el equino. El objetivo de este trabajo fue analizar los alcances, ventajas y limitaciones del estudio ultrasonográfico con Doppler de Poder asociado al Modo B en la evaluación de 122 afecciones músculo-esqueléticas en equinos deportivos, de entre 2 y 15 años, de ambos sexos y distintas razas Se utilizó un ecógrafo portátil Sonoscape E2 con sonda lineal de 7-11 Mhz y convexa de 2,5-5 Mhz. De la totalidad de las lesiones músculo-esqueléticas evaluadas (n:122) se observó presencia de señal con el Doppler de Poder en 46/122 siendo la más observada la de grado I (29/46), seguida del grado II (13/46) y por último de grado III (4/46). Si bien este es un estudio preliminar y faltan más resultados para poder aplicar análisis estadísticos, según la experiencia de los autores, el Doppler de Poder complementando los estudios ultra-sonográficos en Modo B, ha demostrado ser una herramienta de gran utilidad para el diagnóstico, seguimiento de la evolución de las lesiones, evaluación de la respuesta terapéutica y con valor predictivo de posibles lesiones futuras.
