The unexpected discovery of Brucella abortus Buck 19 vaccine in goats from Ecuador underlines the importance of biosecurity measures

Abstract: Very few, mostly old, and only preliminary serological studies of brucellosis in goats exist in Ecuador. In order to assess the current epidemiological situation, we performed a cross-sectional serological study in the goat populations of Carchi (n = 160 animals), Pichincha (n = 224 animals), and Loja provinces (n = 2024 animals). Only two positive serological results (RB negative and SAT-EDTA ≥400 IU/ml) were obtained in lactating goats from the same farm in Quito (Pichincha province). Additionally, milk was sampled from 220 animals in Pichincha province. The present study indicates a low apparent prevalence in Pichincha province and absence in Carchi and Loja provinces. A total of 25 positive milk ring tests (MRT) were obtained in Pichincha province yielding a prevalence of MRT of 11.16%. Subsequent culture was performed on the positive MRT samples. All results were negative, apart from a single sample, obtained from a serologically positive goat in Quito, that was positive for Brucella abortus strain 19 (B19). Several hypotheses are forwarded concerning this unexpected result. The most likely hypothesis is the possible accidental use of a needle, previously used for vaccination of cattle with the said vaccine, for the administration of drug treatment to the goat. This hypothesis underlines the necessity of biosecurity measures to prevent this type of accidents.

Prácticas de riesgo para transmisión de VIH en estudiantes de medicina de Latinoamérica y el Caribe, 2017

Abstract: El objetivo del trabajo fue determinar las practicas de riesgo para transmision de VIH en estudiantes de medicina de Latinoamerica y el Caribe durante los meses de Enero a Febrero de 2017. Se realizo un estudio observacional, descriptivo de corte transversal, con muestreo no probabilistico por conveniencia en estudiantes de medicina de Latinoamerica y el Caribe, desde enero a febrero de 2017. Se escogio a estudiantes de medicina del primer al septimo ano de la carrera. Se procedio a la publicacion en redes sociales del cuestionario electronico mediante Google Doc©. Los resultados se expresan en tablas de frecuencias. Fueron incluidos 638 estudiantes de medicina, teniendo el 67,08% (428) una edad comprendida entre 20 a 24 anos. Del total de encuestados el 56,02% ha practicado sexo anal, 88,65% ha practicado sexo oral, y 57,06% sexo vaginal en los ultimos 6 meses. El 24,43% de los encuestados nunca ha utilizado condon durante sus relaciones sexuales. El 3,49% han pagado alguna vez por sexo, 27,57% ha ingerido alcohol durante las relaciones sexuales y 4,36% ha mantenido relaciones sexuales con usuarios de drogas intravenosas mientras que 63,88% nunca se ha hecho una prueba rapida para VIH. Las practicas de riesgos mas frecuentes fueron la baja utilizacion de condon durante la ultima relacion sexual, la utilizacion de alcohol durante la relacion sexual y la baja realizacion de prueba para VIH.
