A survey of intestinal parasites in dogs from Saskatoon, Saskatchewan

Fresh fecal samples from 124 apparently healthy dogs and 333 random source canine fecal samples from dog walking areas were analyzed by centrifuged flotation in Sheather's solution to determine the prevalence of gastrointestinal parasites in dogs from Saskatoon, Saskatchewan. Fecal flotation was positive in 4.4% of samples. Roundworm species were found in 1.5% of samples, hookworm species were found in 0.4% of samples, whipworm species were found in 0.7%, Strongyloides spp. were found in 0.6%, Giardia spp., Cystoisospora spp., and Alaria spp. were found in 0.4% of samples.     

Investigation of Intestinal Parasites in Dairy Cattle in Parts of Hebei Province and Tianjin

In order to understand the prevalence of intestinal parasites in dairy cattle in Hebei and Tianjin near to Bohai area, the centrifugal precipitation, Sheather's sugar flotation, and Lugol's iodine staining techniques were used to examine 1 040 fecal samples from 12 dairy cattle farms in Hebei and Tianjin areas. The overall infection rate was 61.63%, with the prevalence being 59.78% and 66.12% in Hebei and Tianjin, respectively. Eight parasite species were identified, including Coccidium spp., Giardia duodenalis, Cryptosporidium spp., amoeba, Strongylus spp., Trichuris spp., cestode and trematode, and the infection rates were 40.96%, 1.63%, 8.46%, 33.27%, 2.02%, 3.56%, 0.96% and 0.96%, respectively. Coccidia spp. and amoeba were the predominant parasites. The present study indicated the prevalence of intestinal parasites were universal in dairy cattle in Hebei and Tianjin areas. Thus, the farms should take necessary prevention and control measures.

Presence and persistence of intestinal parasites in canine fecal material collected from the environment in the Province of Chubut, Argentine Patagonia

We investigated the presence of intestinal parasites in canine feces collected from public squares in Comodoro Rivadavia, Chubut, Argentina (45 degrees S, 68 degrees W) and determined the persistence of Echinococcus granulosus eggs in those droppings under natural environmental conditions in that region. In the first experiment, we analyzed 163 fecal samples collected from urban squares during 8 months time and found parasitic elements in 46.6%. The presence of parasites was independent of the condition of the feces (fresh or dried; P>0.05). Parasites potentially pathogenic in man were present, such as Toxocara species (spp.), Taenia spp./Echinococcus spp., Uncinarias spp., and Entamoeba spp. In the second experiment, we analyzed two canine fecal samples contaminated with E. granulosus eggs, deposited for 41 months within the natural environment. These parasitic elements persisted during the entire study as attested by light microscopy and the ELISA coproantigen test. We propose the study of the presence of intestinal parasites in canine feces within the environment as a general strategy for identifying and monitoring areas of risk for canine-related zoonoses since we were able to demonstrate the persistence of E. granulosus eggs in deposited canine feces for over 3 years within the area studied.     

Prevalence of Microsporidia, Cryptosporidium spp., and Giardia spp. in beavers (Castor canadensis) in Massachusetts.

Feces from 62 beavers (Castor canadensis) in Massachusetts were examined by fluorescence microscopy (IFA) and polymerase chain reaction (PCR) for Microsporidia species, Cryptosporidium spp., and Giardia spp. between January 2002 and December 2004. PCR-positive specimens were further examined by gene sequencing. Protist parasites were detected in 6.4% of the beavers. All were subadults and kits. Microsporidia species were not detected. Giardia spp. was detected by IFA from four beavers; Cryptosporidium spp. was also detected by IFA from two of these beavers. However, gene sequence data for the ssrRNA gene from these two Cryptosporidium spp.-positive beavers were inconclusive in identifying the species. Nucleotide sequences of the TPI, ssrRNA, and beta-giardin genes for Giardia spp. (deposited in GenBank) indicated that the four beavers were excreting Giardia duodenalis Assemblage B, the zoonotic genotype representing a potential source of waterborne Giardia spp. cysts.
