Objetivo. Conocer el estado serológico de hembras bovinas a IBR, DVB, leucosis, leptospira y Neospora caninum en el departamento de Santander, Colombia. Materiales y métodos. Se realizó un muestreo por conveniencia en 460 fincas ganaderas de 23 municipios de Santander (Colombia), los sueros colectados fueron analizados mediante diferentes kits comerciales de ELISA siguiendo las instrucciones del fabricante. Resultados. En todas las enfermedades estudiadas se encontraron animales seroreactores, correspondiendo la prevalencia general a Leucosis 21.8%, Leptospira 26.1%, DVB 29.7%, IBR 48.2% y Neospora 63 %. Conclusiones. En el departamento de Santander las enfermedades analizadas se encuentran en la población bovina con prevalencias que fluctúan entre medio a alto, lo cual requiere medidas de control oficial.
The KARS gene encodes the aminoacyl-tRNA synthetase (aaRS) which activates and joins the lysin with its corresponding transfer RNA (tRNA), through the ATP-dependent aminoacylation of the amino acid. The KARS gene mutations have been linked to diverse neurologic phenotypes such as: neurosensorial hearing loss, leukodistrophy, microcephaly, developmental delay or regression, peripheral neuropathy, cardiomyopathy, impairment of the mitochondrial respiratory chain, hyperlactatemia, among others. This article presents the case of a Colombian pediatric patient with two pathological missense variants in a compound heterozygous state in the KARS gene.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
