Objetivo. Verificar la presencia del virus de la enfermedad de Newcastle (ENC) en aves de sistemas productivos de traspatio (SPT) de parte de la zona central de Chile. Materiales y métodos. Entre 2013 y 2015, un total de 1,579 hisopados orotraqueales…

Los elementos contaminantes en la atmosfera terrestre, específicamente a lo largo del espacio que corresponde a la tropósfera, el NO2 se dispersan cada vez a mayores altitudes cubriendo desde 0 metros sobre el nivel del mar hasta los diez mil metros…

Our ability to respond appropriately to infectious diseases is enhanced by identifying differences in the potential for transmitting infection between individuals. Here, we identify epidemiological traits of self-limited infections (i.e. infections…

Highly pathogenic avian influenza A (HPAI) subtype H5N1 has caused family case clusters, mostly in Southeast Asia, that could be due to human-to-human transmission. Should this virus, or another zoonotic influenza virus, gain the ability of sustained…

Bat populations harbour a multitude of viruses; some of these are pathogenic or potentially pathogenic in other animals or humans. Therefore, it is important to monitor the populations and characterize these viruses. In this study, the presence of…

We characterized novel coronaviruses detected in US bottlenose dolphins (BdCoVs) with diarrhea. These viruses are closely related to the other 2 known cetacean coronaviruses, Hong Kong BdCoV and beluga whale CoV. A deletion in the spike gene and…

Abstract Background Middle East respiratory syndrome coronavirus (MERS-CoV), which belongs to beta group of coronavirus, can infect multiple host species and causes severe diseases in humans. Multiple surveillance and phylogenetic studies suggest a…

In Ohio, United States, in early 2014, a deltacoronavirus was detected in feces and intestine samples from pigs with diarrheal disease. The complete genome sequence and phylogenetic analysis of the virus confirmed that the virus is closely related to…

During an inspection in plastic houses in Sapopema, Paraná, 90% of tomato plants showed leaf abnormalities, probably associated with herbicide toxity. However, virus like symptoms developed in selected hosts after mechanical inoculatation. RT-PCR…

Bat coronaviruses (Bt-CoVs) are thought to be the precursors of severe acute respiratory syndrome coronavirus. We detected Bt-CoVs in 2 bat species from Trinidad. Phylogenetic analysis of the RNA-dependent RNA polymerase gene and helicase confirmed…
