The cyst-forming protozoan parasite Neosporacaninum is one of the main causes of bovine abortion worldwide and is of great economic importance in the cattle industry. Recent studies have revealed extensive genetic variation among N. caninum isolates based on microsatellite sequences (MSs). MSs may be suitable molecular markers for inferring the diversity of(More)
We developed a sensitive nested polymerase chain reaction procedure for the Cryptosporidium oocyst wall protein (COWP) gene. Amplification and genotyping were successful in 95.2% of 1,680 fecal samples, 77.6% by the unnested and 17.6% by the nested COWP procedure. The COWP gene was amplified from 2,128 fecal samples: 71 from livestock animals and 2,057 from(More)
Information on helminth parasites in Antarctic phocids is scarce and fragmented. Anisakidae nematodes and Diphyllobothriidae cestodes have been reported in Antarctic and subantarctic phocids, although the prevalence and health significance remain unclear. In the present study, the presence of helminth parasites in faeces of Leptonychotes weddellii, Hydrurga(More)
