“…Lineage IV MRCA originated between 1978 and 2001. During these periods, records indicate illegal importation of cattle and bovine semen from Nicaragua [51]. Unfortunately, we do not have WGS or isolates from Nicaragua to test this association.…”

“…Lineages III and IV were more recent introductions. Lineage III MRCA likely occurred sometime between 1907 and 1990, at the time that most creole cattle were replaced with European and South American breeds [51]. Lineage IV MRCA originated between 1978 and 2001.…”

“…Unfortunately, the metadata obtained from the hosts only specifies that the animals were of both breeds, not allowing us to determine which were Bos indicus and which Bos taurus. The youngest lineage IV, with a median estimated date at the year 2001, shows a more recent introduction, that could have originated from illegal introduction of semen and cattle from Nicaragua that have occurred sporadically from 1986 to 2011 [51].…”

Persistence of Brucella abortus lineages revealed by genomic characterization and phylodynamic analysis

Brucellosis, caused by Brucella abortus, is a major disease of cattle and humans worldwide distributed. Eradication and control of the disease has been difficult in Central and South America, Central Asia, the Mediterranean and the Middle East. Epidemiological strategies combined with phylogenetic methods provide the high-resolution power needed to study relationships between surveillance data and pathogen population dynamics, using genetic diversity and spatiotemporal distributions. This information is crucial for prevention and control of disease spreading at a local and worldwide level. In Costa Rica (CR), the disease was first reported at the beginning of the 20 th century and has not been controlled despite many efforts. We characterized 188 B. abortus isolates from CR recovered from cattle, humans and water buffalo, from 2003 to 2018, and whole genome sequencing (WGS) was performed in 95 of them. They were also assessed based on geographic origin, date of introduction, and phylogenetic associations in a worldwide and national context. Our results show circulation of five B. abortus lineages (I to V) in CR, phylogenetically related to isolates from the United States, United Kingdom, and South America. Lineage I was dominant and probably introduced at the end of the 19 th century. Lineage II, represented by a single isolate from a water buffalo, clustered with a Colombian sample, and was likely introduced after 1845. Lineages III and IV were likely introduced during the early 2000s. Fourteen isolates from humans were found within the same lineage (lineage I) regardless of their geographic origin within the country. The main CR lineages, introduced more than 100 years ago, are widely spread throughout the country, in contrast to new introductions that seemed to be more geographically restricted. Following the brucellosis prevalence and the farming practices of several middle-and low-income countries, similar scenarios could be found in other regions worldwide.

“…Las diferencias encontradas en los NT (alto, medio y bajo) entre las UP (pastizales, alimentación, registros, manejo, sanidad, reproducción, instalaciones y equipo), son atribuibles a la heterogeneidad que hay entre los productores en regiones tropicales (Vilaboa-Arroniz et al 2009). Estas diferencias radican principalmente en la utilización de componentes tecnológicos, finalidad productiva (leche, carne y DP), superficie pecuaria, unidades animal, carga animal, venta de animales por año y si la UP pertenece a un particular o a una Institución (Vilaboa y Díaz 2009, Vilaboa-Arroniz et al 2012a. Estos aspectos confieren particularidades en los procesos de innovación, adopción de tecnología y rentabilidad de la UP (Vilaboa-Arroniz et al 2009, Vilaboa y Díaz 2009.…”

RESUMEN. El objetivo fue caracterizar el nivel tecnológico (NT), registrar la edad y peso al primer estro y primer servicio en vaquillas Criollo Lechero Tropical (CLT) en Méxio. Se emplearon nueve unidades de producción (UP). Las UP tuvieron un 33.3, 44.4 y 22.3% de NT bajo, medio y alto, respectivamente. La edad (meses) y peso al primer estro (kg) según el NT de las UP fue de 20.0 ± 3.0 y 280.0 ± 33.3 para NT bajo, 18.2 ± 1.64 y 286.3 ± 20.0 para NT medio y, 15.0 ± 1.6 y 260.0 ± 35.0 para NT alto, respectivamente. La edad (meses) y peso al primer servicio (kg) según el NT de las UP fue de 22.1 ± 2.0 y 310.0 ± 25.3 para NT bajo, 20.6 ± 2.0 y 319.5 ± 22.6 para NT medio y 17.5 ± 1.5 y 291.0 ± 30.1 para NT alto, respectivamente. La edad y peso al primer estro y primer servicio varía según el nivel tecnológico de la UP.

“…Então, 30,50% da população estão em situação de vulnerabilidade socioeconômica, segundo a metodologia utilizada neste estudo 43%, se encontra dentro do intervalo do risco alto de vulnerabilidade (INDER, 2016). A principal causa, possivelmente, é alta taxa de desemprego, acompanhada da pouca oferta laboral, onde as principais atividades comerciais até o dia de hoje são: criação de gado e cultivo da cana-de-açúcar, arroz, leiteria, serviços públicos e privados; nos últimos anos se incorpora as atividades de turismo e piscicultura (especialmente lagostim), a renda familiar é menor que um salário base, o seja, 526 UMR, limitando o poder aquisitivo e acesso a educação superior (BLANCO, 2016;CHANT;MORENO, 2005;CHEN, 2015;IÑAMAGUA-UYAGUARI et al, 2016;MARCHENA, 2015;VILABOA-ARRONIZ et al, 2012). A condição mostra vulnerabilidade socioeconômica das famílias e assinala a urgência de atendimento, principalmente para condição de mudanças climáticas, que força a ações de adaptação e prevenção dessas populações.…”
