En últimas décadas se registró aumento exponencial casos, probablemente asociado a disminución inmunidad conferida por vacuna antivariólica, discontinuada luego erradicación viruela. los últimos años registraron casos esporádico...

Zoonosis has been suggested for hepatitis E virus (HEV) infection, but so far is based only on indirect evidence. We experienced a series of cases of HEV infection among people who had eaten uncooked deer meat 6-7 weeks before. On testing, a left over portion of the deer meat, kept frozen to eat in the future, was positive for HEV RNA, whose nucleotide sequence was identical to those from the p...

In a world where most emerging and reemerging infectious diseases are zoonotic in nature and our contacts with both domestic and wild animals abound, there is growing awareness of the potential for human acquisition of animal diseases. Like other Pasteurellaceae, Pasteurella species are highly prevalent among animal populations, where they are often found as part of the normal microbiota of the...

Numerous echinostome trematodes are found in the intestines of birds and mammals throughout the world, and echinostomiasis in humans has been attributed to approximately 16 different species. In humans it is usually regarded as a rare intestinal parasite of little clinical importance except in heavy infections. Diagnosis of echinostomiasis is made by identification of eggs during fecal examinat...

Tularemia, also known as "rabbit fever," is a zoonosis caused by the facultative intracellular, gram-negative bacterium Francisella tularensis. Infection occurs through contact with infected animals (often hares), arthropod vectors (such as ticks or deer flies), inhalation of contaminated dust or through contaminated food and water. In this review, we would like to provide an overview of the cu...
