• Abstract

  Coccidiosis, a disease caused by protozoa of the genus Eimeria, is one of the most economically important diseases for the poultry industry. Seven species of Eimeria infect the domestic fowl (E. acervulina, E. praecox, E. mitis, E. maxima, E. necatrix, E. brunetti, and E. tenella). In addition, three genetic variants, named operational taxonomic units (OTUs x, y and z) were recently detec…

  Detection and molecular characterization of the species and genetic variants of Eimeria spp. in extensive, semi-intensive and intensive broiler and layer chicken farms from the west of the state of Santa Catarina and northwest of the state of São Paulo, AP.R

• Abstract

  Protozoa of the genus Cryptosporidium belong to the phylum Apicomplexa, class Gregarinomorphea, present epicellular localization in the mucosal epithelia, particularly the gastrointestinal tract and, occasionally, also infect the respiratory, biliary and urinary tract, causing clinical and subclinical disease in vertebrates. Several Cryptosporidium species and genotypes are zoonotic. For …

• Abstract

  Cryptosporidiosis has already been described in many animal species, including amphibians, birds, mammals, fishes and reptiles. Human infection has been described in more than 90 countries from six continents. Even there is no consensus about the definitive classification for Cryptosporidium species, some authors suggest that there are, at least, 27 valid species. This study aims to deter…

• Abstract

  Cryptosporidium spp. are intracellular protozoan parasites that infect the epithelial cells of digestive and respiratory tracts of a wide variety of vertebrates. This parasite may cause self-limiting diarrheal illness in immunocompetent individuals, but in immunocompromised patients it may be fatal. Cryptosporidium parvum has many animal hosts and it is one of the dominant Cryptosporidium…

• Abstract

  Cryptosporidium cuniculus was originally detected in rabbits and it has been identified as a human pathogen. However, the incidence, prevalence, and epidemiology of cryptosporidiosis due to C. cuniculus in rabbits and in human populations are still poorly studied. As the identification of C. cuniculus can be time consuming and expensive using the existing molecular assays, such as nested …
