[QUOTE="Lucky_P, post: 1072382, member: 12607"] I'm frequently dismayed - and sometimes embarassed at - stuff my professional colleagues sometimes tell their clients. I teach parasitology to animal health tech/pre-vet students, so maybe I'm more engaged in the minor details of life cycles, host-specificity, etc., but I can guarantee you that the parasitologists who taught me in veterinary school made it very clear that chicken coccidia cannot infect cattle. Avian species coccidia pose no problem for mammals. Plenty of online articles from reliable sources - google 'em up; some even address the host-specificity aspect, particularly with regard to poultry - 'cause it's an old falsehood that just keeps getting repeated. Cryptosporidium is a common problem in dairy calves - but I see it in beef calves from time to time, especially if it's cold and muddy. While it is a pathogen in its own right, I look at it as an 'indicator' organism: if the calf has Crypto, it's almost certainly immunosuppressed - whether due to environmental stress, poor plane of nutrition, faulty colostrum management - or, in many cases, it has one or more other enteric pathogens present, like rota/corona viruses, BVD virus, enteropathogenic E.coli, or Salmonella. It's not at all uncommon for me to see calves with rotavirus, pathogenic E.coli, Crypto, and Strongyloides(threadworms). Most immunocompetent humans who contract Crypto may have some diarrhea for a few days, but rarely require hospitalization. It can, however, be a potentially life-threatening - and sometimes lifelong - infection in HIV+ individual, or those on immunosuppressive drug therapy. There have been numerous 'outbreaks' of human Cryptosporidiosis linked to contamination of municipal water supplies (Milwaukee, Wash.DC, etc.), contaminated public pools/water parks, and day-care centers. It's a tiny little organism that is resistant to chlorination of water. [/QUOTE]
