“…The seroprevalence against BHV-1 in unvaccinated cattle herds, in western lowlands of Ecuador was determined and had a high value of positive animals with 58.47 %. This value was like that reported in other studies, including unvaccinated herds [1], which showed high seroprevalences, above 50 % [2,3,6,12,21,24]. The high number of positive animals may be related to different factors, including the isolate involved [1], the ability of the virus to remain latent, the introduction of infected animals that spread disseminate and perpetuate the virus within the herds [9,29] and the control measures implemented [15].…”

“…Bovine herpesvirus type 1 (BHV-1) is a member of the Herpesviridae family, subfamily Alphadenovirinae [1,18,29], which in ruminants, domestic and wild, form a large group of pathogens with high morbidity [20,22]. BHV-1 is responsible for economic losses in milk production worldwide [5,24], due to the use of medications, milk discarding, mortalities [3,10,20,25] and reproductive failures, such as embryonic death or abortions [6,15], increasing the importance, due to the lack of regularization and the globalization of animal markets or their products [13,16].…”

“…These differences between studies could be due to types of productive systems [20,24], preventive measures used [1,24], or the viral isolate involved [20]. Among the factors that have been reported as risk, there is mainly age, where older animals are the ones with the highest seroprevalence [6,7,12,24,29], sex [1,24], the history of reproductive problems in herds [12,20], and the non-implementation of preventive measures [14,15,18,20,28,29]. BHV-1 antibodies levels frequency in Ecuador was established at 43 % [7], but additional studies have not been reported and the current status of the disease is unknown.…”

In order to determine the antibodies levels against Bovine Herpesvirus type 1 (BHV-1) and associated risk factors in unvaccinated dairy herds of tropical wet weather of Ecuador, an investigation was carried out in thirteen production units (PU), in the Chone Canton, Province of Manabí. The sample size was calculate by cluster sampling and the variables to be evaluated were antibodies levels frequency, age, sex, ocular or vulvovaginal lesions, breed and PU. One hundred eighty three blood samples were taken from the jugular or caudal vein and labeled for transfer to the laboratory. The tubes were centrifuged at 3,220 g for 15 minutes and the sera were transferred to Eppendorf tubes that once labeled were stored at –20°C until processing. Antibodies levels against HBV-1 were measured through of competitive ELISA technique, and calculated with simples statistical. The risk factors were estimated through the Odds ratio and relative risk, and the significance level through the Chi-square. The general antibodies levels frequency was 58.47 %. According age, 28.57 % in animals under two years old (yr.old) and 67.38 % for cattle over two yr.old. According to the sex, males showed 18.18 % and females 82.61 %. The determined risk factors (P<0.05) were age and sex, with a significant relative risk (P<0.05) of 3.31 and 2.32, respectively. The unvaccinated dairy herds of Western lowlands of Ecuador, have high antibodies levels frequency against BHV-1, with females over two yr.old at the highest risk of presenting infectious bovine rhinotracheitis (IBR).

“…In Colombia, has been reported sero-prevalence of BLV at municipal level, in the following states: Antioquia 44-47.8% (25,29) (39). In this sense, the report of BLV in Colombia varied between 11.2 to 77.83%, therefore, the prevalence of the disease in Caquetá state (25.18) is between national ranges, nevertheless, it is greater to the prevalence in Casanare, Córdoba, and Nariño, but lower than the others states.…”

Bovine Leukemia Virus (BLV) is the agent of enzootic bovine leukosis (EBL), this disease is a neoplasm of lymphatic tissue in bovine species. The aim of this article was determinate the prevalence of bovine leukemia virus in dual-purpose cattle from nine municipalities that produce the 98% of milk in the Caquetá state, Colombia. Blood samples were collected in 100 herds dedicates to dual purpose cattle, obtained blood serum from 1000 animals, of which 893 corresponding to cows. Indirect Elisa test for detection of antibodies anti-GP51 of BLV was performance and the positive cases were considered if the serum-to-positive ratio with percentages of M/N lower than 40%. Categorized data were analyzed by contingency tables and ANOVA at the significant level of p<0.05 by DGC test was performed. The overall sero-prevalence of BLV in Caquetá state was of 25.18% (95%, CI: 21.9-28.46%), in males 26.25% and females 25.37% respectively. At municipal level the sero-prevalence varied of 7.12 to 41.81%. The prevalence of BLV at herd level was of 67% (95%, CI: 57.24-76.76%). In conclusion, the sero-prevalence of BLV in the dual-purpose livestock system over 36 months of age in Caquetá state is moderate, do not exist statistical difference between sero-prevalence of cows and bulls. At level of herds the prevalence of BLV is high. Improving strategies of control and managements in the herds, as well as implement policies of sanitary management are necessary.

Este artículo presenta los resultados de un estudio documental sobre convivencia escolar, habilidades socioemocionales y la solución de conflictos en el aula para la formación ciudadana de los estudiantes de básica primaria. Se identifican cuatro tendencias relacionadas con los temas de interés: a) las habilidades socioemocionales en la convivencia escolar. b) el conflicto escolar. c) la convivencia y construcción de ciudadanía. El análisis de las investigaciones muestra concordancia en el interés por las habilidades socioemocionales como una alternativa para aprender a resolver conflictos, mejorar la convivencia escolar en las aulas, y en la formación de ciudadanía de los estudiantes de primaria. Estos temas aportan a la producción de conocimiento del macroproyecto de investigación "Diálogo de saberes entre las organizaciones sociales y las instituciones educativas de la subregión sur del departamento del Huila para articular esfuerzos en la construcción de ciudadanía como estrategia de defensa de la vida”.
