Introduction: Hepatitis A is caused by a virus of the family Picornaviridae, genus Hepatovirus. It fecal-oral disease that can cause jaundice, nausea, abdominal pain, fever, dark urine, among other symptoms. In Portugal vaccine not part National Vaccination System, however it advised to all individuals who travel endemic areas. Currently endemicity region classified when 50% population, specifi...

Foot and Mouth Disease (FMD) is a viral infectious disease that acute highly contagious in artiofactyl or even-toed hoofed animals. This caused by tyoe A virus forum picornaviridae, genus Apthovirus namely Aphtaee epizootecae. has development period of 1-14 days since the infected animal. The defense this quite strong survives glands, milk bones products. morbidity rate up to 100% mortality hig...

Human parechoviruses (HPeV), previously designated as echovirus 22 and 23, belong to the Parechovirus genus within the Picornaviridae family and has been designated HPeV 1 and 2 respectively.1 The HPeV genome organization and disease spectrum are similar to other viruses in the Picornaviridae family. HPeV have been frequently associated with respiratory and gastrointestinal diseases in children...

The contemporary surge in metagenomic sequencing has transformed knowledge of viral diversity wildlife. However, evaluating which newly discovered viruses pose sufficient risk infecting humans to merit detailed laboratory characterization and surveillance remains largely speculative. Machine learning algorithms have been developed address this imbalance by ranking the relative likelihood human ...

Foot-and-mouth disease virus (FMDV) is thought to evolve largely through genetic drift driven by the inherently error-prone nature of its RNA polymerase. There is, however, increasing evidence that recombination is an important mechanism in the evolution of these and other related picornoviruses. Here, we use an extensive set of recombination detection methods to identify 86 unique potential re...

A candidate new canine picornavirus was isolated from a respiratory swab collected from an American foxhound (Canis lupus familiaris) in 1968. The assembled genome sequence of strain A128thr is 7,618 bases in length, comprising a complete protein-coding sequence of the 2,213-amino-acid polyprotein and partial terminal untranslated sequences.
