Based on findings demonstrating the simian ancestry of HIV, AIDS has been reported to be a zoonosis. However, this theory has never been proved and must seriously be questioned. Several arguments show that HIV-AIDS is not a zoonosis. (i) If AIDS were a zoonosis, there must be evidence of AIDS being directly acquired from an animal species, as is rabies, a disease that is directly acquired from ...

Borreliosis caused by Borrelia burgdorferi sensu lato is a cosmopolitan zoonosis studied worldwide; it is called Lyme disease in many countries of the Northern Hemisphere and Lyme-like or Baggio-Yoshinari Syndrome in Brazil. However, despite the increasing number of suspect cases, this disease is still neglected in Brazil by the medical and veterinary communities. Brazilian Lyme-like borreliosi...

Zoonosis refers to the transmission of infectious diseases from animal to human. The increasing number of zoonosis incidence makes the great losses to lives, including humans and animals, and also the impact in social economic. It motivates development of a system that can predict the future number of zoonosis occurrences in human. This paper analyses and presents the use of Seasonal Autoregres...

in this survey 45 carnivores including 14 jackals, 23 stray dogs, 2 foxes, 2 domestic cats, 1 wild cat, 2 swine and 1 wolf were collected. on post-mortem examination, 84% carcases were infected and 13 zoonotic helminth species were recovered. dirofilaria immitis was the most commonly parasite and toxocara canis showed the highest intensity of infection. one species from swine and two helminth s...

The main cause of human infectious diseases and public health threats these days has been thought to be “emerging and re-emerging diseases” such as BSE, highly pathogenic avian influenza (HPAI), SARS, etc. These infectious diseases were derived from pathogens from animals (zoonosis) and their products (food-borne infections). Recent zoonoses worldwide are reviewed here by origin, environment an...

Background: Contagious ecthyma or orf is a poxviral disease of goat and sheep, with incidental infection appearing in humans, cows, camels, and many wild ruminants, and very rarely in dogs. Case description: In the present paper was described gross morphology and histopathology of contagious ecthyma in a dog with a large ulcerated cutaneous mass in the neck (under the collar) which was ma...

Several approaches and models have been proposed to simulate the spread of infectious diseases such as West Nile virus (WNV) or Lyme disease. However, these models such as mathematical models have some weaknesses when trying to simulate the influence of geographic features on the disease spread. In this context, we developed a new theoretical model called MASTIM to remedy some shortcomings of c...
