| new species of cryptosporidium tyzzer, 1907 (apicomplexa) from amphibian host: morphology, biology and phylogeny. | cryptosporidium fragile sp. n. (apicomplexa) is described from black-spined toads, duttaphrynus melanostictus (schneider) (amphibia, anura, bufonidae) from the malay peninsula. the parasitized animals were directly imported from malaysia and harboured c. fragile at the time of arrival. oocysts were subspherical to elliptical with irregular contour in optical section, measuring 6.2 (5.5-7.0) x 5.5 (5.0-6.5) microm. oocyst wall was smooth and colourless in light microscopy. the endogenous developm ... | 2008 | 18666410 |
| occurrences and genotypes of cryptosporidium oocysts in river network of southern-eastern china. | transportation of cryptosporidium oocysts in river type source water is of great concern in an area where extensive human activities exist. in this study, a total of 47 samples were collected from tongxiang, china, where drinking source water was taken from a complicated river network system, by three sampling campaigns over a rainy season in 2009, to reveal the presence, genotypes, and likely source of cryptosporidium oocysts in river water. immunofluorescence microscopy analyses show that 37 ( ... | 2011 | 22006191 |
