The lucrative, outlandish, nonsensical action-horror franchise has made over a billion dollars, entertained audiences all over the world, ticked off film critics, and infuriated die-hard fans of the games, which Anderson didn’t so much adapt as throw in a blender. Anderson’s “Resident Evil” movies, because most people already have. He also said warmer weather might mean people leave their cats outdoors for a larger portion of the year, increasing the chances of infection.Say what you will about Paul W.S. "We could see that potentially facilitating transport pathways and exposure pathways in environments that may not have been a problem before." "Intense rainfall, for example, which might be expected to occur as a result of climate change in many regions of Canada - that could be a factor," he said. "Getting exposed may not be as difficult as we might think."Ĭlimate change might also be influencing the survival and movement of the parasite, Lapen said. And moves around and gets ingested and fecal matter gets ingested or animals get ingested," he said. "There's contamination of soil and water. The eggs can then live for years in soil and water, with the potential to infect any bird or mammal, including humans, said David Lapen, a research scientist for Agriculture and Agri-Food Canada.
The study said one infected cat can excrete as many as 500 million toxoplasma eggs in just two weeks. "Outdoor cat owners need to understand what they're exposing their neighbours to," she said. Wilson said responsible pet management could alleviate the spread of the parasite and, in turn, the risk to wildlife and humans. In healthy animals and humans, the parasite can remain dormant and rarely causes direct harm. The disease has also been linked to nervous system disorders, cancers and other debilitating chronic conditions. Toxoplasmosis, also known as kitty litter disease, can cause blindness and miscarriages in humans and can be fatal for those with weakened immune systems. "They're pushing infection rates within natural populations beyond what they normally are exposed to." They're the only ones that can secrete oocysts into the environment," Wilson said. "At the core of the toxoplasma life cycle are our cats - domestic cats and wild cats. The study analyzed over 45,000 cases of toxoplasmosis in wild animals, using data from more than 200 global studies.Īccording to their findings, Wilson said domestic cats are "the most consequential host for toxoplasma," since infected cats can excrete the parasite's eggs in their feces. Amy Wilson, an adjunct professor at UBC's Department of Forest and Conservation Sciences. And as the population of cats goes up, we expect the number of free-roaming cats to increase as well," said study lead Dr. "As human density goes up, the population of cats is going to go up as well. The research found that Toxoplasma gondii - a common parasite that infects most warm-blooded animals, including humans, and causes the disease toxoplasmosis - is more likely to infect wildlife where human density is higher. (The Associated Press - image credit)Ī new University of British Columbia study has found that free-roaming cats - both domestic and feral - are likely to blame for the spread of a potentially deadly parasite in densely populated urban areas. Domestic cats are 'the most consequential host for toxoplasma,' since infected cats can excrete toxoplasma eggs in their feces, study lead Dr.
