Prevalence and species identification of Cryptosporidium from fecal samples of horses in Taiwan.

Cryptosporidiosis is a zoonotic disease caused by the protozoan parasite Cryptosporidium. A total of 436 horse fecal samples were collected from 19 farms, and acid-fast staining method was used for primary screening. Cryptosporidium oocysts were found in 161 samples, among which 33 positive sample were selected for nested PCR, restriction fragment length polymorphism analysis and DNA sequencing of 18 S rDNA, showing 31 samples to be bovine C.

Development of PCR-RFLP method to distinguish between Cryptosporidium parvum and C. hominis in Taiwan water samples.

Cryptosporidium, a protozoan pathogen that causes cryptosporidiosis has emerged as an important source of diarrheal illness among humans and animals. The current routine laboratory technique used for Cryptosporidium diagnosis is light microscopy with acid-fast staining but the technique has low efficiency and sensitivity for species-specific identification. Single PCR to amplify a 220 bp fragment of 18 S ribosomal DNA of C.

Triggering receptor expressed on myeloid cells (TREM)-1 participates in Schistosoma mansoni inflammatory responses.

Inflammatory responses to microbial products are amplified by a pathway mediated by triggering a receptor expressed on the myeloid cells (TREM)-1. Relatively a few studies have been performed to investigate the role of TREM-1 in macrophage activation in response to parasitic infection. In this study, we delineate the role of the innate immunoreceptor TREM-1 in the parasite Schistosoma mansoni infection model from early to late (chronic) phases of infection.

Diagnosis of schistosomiasis using recombinant fructose-1,6-bisphosphate aldolase from a Formosan strain of Schistosoma japonicum.

Schistosoma japonicum obtained from Taiwan is a zoophilic strain that only infects domestic and small animals. Recombinant fructose-1,6-bisphosphate aldolase (FBPA) derived from this strain was used as an antigen in an enzyme-linked immunosorbent assay (ELISA) for the diagnosis of human schistosomiasis. The full-length DNA sequence of FBPA was found to be 1092 bp, encoding a protein of 363 amino acid residues, with a molecular mass of 39.
