Cryptosporidium Parvum Objective The objective of this study is to examine the role of the pathogen, Cryptosporidium parvum in human health and disease and public health. Included will be the appropriate microscopic, cultivation and non-cultivation methods for the chosen pathogen and the application to clinical microbiology processing for that bacterium. Also examined will be human and microbe relationships and an analysis of the virulence factors of microorganism and host factors to types and outcomes with public health emphasized. Crytosporidium parvum in as infectious agent reported to have the following characteristics: (1) Coccidian protozoa; sporozoa; (3) sexual and asexual cycles in a single host; (4) sporotoites, tophozoites and merozoites all attach to epithelial cells (typically intestinal cells); and (5) mature oocyst contains four thin, flat motile sporozoites (204 by 6-8µm). (Public Health agency of Canada, 2013, p.1) Characteristics Crytosporidium parvum is characterized by "profuse, watery diarrhea, cramping, abdominal pains, weight loss, anorexia, flatulence and malaise; nausea, vomiting, fever and myalgias may also be present; symptoms are self-limiting in healthy individuals; immunocompromised patients including AIDS patients may experience prolonged symptoms with increasing severity." (Public Health of Canada, 2013, p.1) The range of hosts for cryptosporidium parvum includes humans, fish, reptile, poultry, and large and small mammals. (Public
