La evolución de la peste porcina africana en China: ¿una amenaza global?

Publicamos un nuevo artículo de acceso abierto titulado "The Evolution of African Swine Fever in China: A Global Threat?" en la revista Frontiers in Veterinary Science.

Resumen: African swine fever (ASF) is one of the most critical diseases in the pig industry. In Asia, 15 countries have already reported an outbreak as of November 22, 2021. In 2021, China reported the genotype II lower virulent ASF virus (ASFV) and the emergence of genotype I ASFV. ASF is generally known as a contagious and lethal disease, but if chronic infection spreads, then disease control would be more difficult. In the current study, we highlighted the possibility of lower virulent virus distribution throughout China and the subsequent general risk of the virus being released from the country. The kernel density estimation showed that the two highest kernel density areas of ASF notification were located in Northeast and Midwest China. Four of the five provinces where lower virulent ASFV was isolated overlapped with areas of relatively high ASF notification density. In terms of the risk of ASFV spreading from China, eight of the 10 largest airports and three of the 10 largest seaports are located in areas of relatively high ASF notification density. There were flight flow from China to 67 countries and ship flow to 81 countries. Asia had the highest flight flow, followed by Europe, North America, Africa, and Oceania. The highest number of ship flows was also concentrated in Asia, but about 10% of ships head to Africa and South America. Chinese overseas residents were distributed in each continent in proportion to these results. Here, we highlight the potential risk of ASFV spread from China to the world.

Infección por SARS-CoV-2 en gatos

Nueva publicación en la revista Veterinary Research Communications titulada: "Evaluation of the clinical evolution and transmission of SARS-CoV-2 infection in cats by simulating natural routes of infection".

Resumen: Severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) is the causative agent of the current pandemic disease denominated as Coronavirus Disease 2019 (COVID-19). Several studies suggest that the original source of this virus was a spillover from an animal reservoir and its subsequent adaptation to humans. Of all the different animals affected, cats are one of the most susceptible species. Moreover, several cases of natural infection in domestic and stray cats have been reported in the last few months. Although experimental infection assays have demonstrated that cats are successfully infected and can transmit the virus to other cats by aerosol, the conditions used for these experiments have not been specified in terms of ventilation. We have, therefore, evaluated the susceptibility of cats using routes of infection similar to those expected under natural conditions (exposure to a sneeze, cough, or contaminated environment) by aerosol and oral infection. We have also evaluated the transmission capacity among infected and naïve cats using different air exchange levels. Despite being infected using natural routes and shed virus for a long period, the cats did not transmit the virus to contact cats when air renovation features were employed. The infected animals also developed gross and histological lesions in several organs. These outcomes confirm that cats are at risk of infection when exposed to infected people, but do not transmit the virus to other cats with high rates of air renovation.

Diagnóstico de Laboratorio de la Peste Porcina Africana

VACDIVA: I Seminario Internacional para Cazadores

El proyecto H2020 de la UE VACDIVA «Una vacuna segura y DIVA para el control y la erradicación de la Peste Porcina Africana» te invita a participar en este encuentro. El seminario será online, el 8 de febrero de 2022, de 9:30 a 14:00 CET.

Repasaremos la situación de riesgo global y los avances en el desarrollo de una vacuna segura, eficaz y DIVA. La reunión tendrá como objetivo actualizar la situación en torno a la Peste Porcina Africana, presentando los objetivos y resultados ya obtenidos a través del proyecto VACDIVA, pero también incluirá diferentes presentaciones y debates sobre tres temas principales:

Vacunas eficaces y seguras contra la Peste Porcina Africana en jabalíes y cerdos domésticos.
Pruebas DIVA para los candidatos vacunales.
Estrategias de control y erradicación de la PPA en diferentes escenarios epidemiológicos del mundo y prueba piloto de vacuna en entorno real.
