Parasite Exposure

Cats and dogs carry a wide range of parasites with zoonotic potential. While much focus is placed on protecting owners and the wider public from these infections, veterinary staff are also at risk of exposure. Veterinary nurses may be exposed to parasites through direct contact with pets, indirect surface transmission, aerosols or via vectors. The risk of zoonotic parasite transmission, however, can be minimised in the workplace with a few simple practice-wide precautions. This article considers some of the routes of parasite exposure in practice and steps to reduce them.

Low Prevalence

SUMMARYAlthough local prevalence of Echinococcus multilocularis may be high, this zoonotic parasite has an overall low prevalence in foxes and rodents in Sweden. To better understand opportunities for E. multilocularis transmission in the Swedish environment, the aim of this study was to investigate other taeniid cestodes and to relate observed patterns to E. multilocularis. Cestode parasites were examined in fox feces and rodents caught in different habitats from four regions of Sweden. Arvicola amphibius and Microtus agrestis were parasitized with Versteria mustelae, Hydatigera taeniaeformis s. l., and E. multilocularis, whereas Myodes glareolus and Apodemus spp. were parasitized with V. mustelae, Taenia polyacantha, H. taeniaeformis s.l., and Mesocestoides spp. Rodents caught in field habitat (Ar. amphibius, Mi. agrestis) were more likely (OR 10, 95% CI 5–19) to be parasitized than rodents caught in forest habitat (My. glareolus, Apodemus spp.). The parasite preference for each rodent species was present regardless of the type of background contamination from fox feces. These results further support the importance of both ecological barriers and individual species susceptibility in parasite transmission, and indicate that future monitoring for E. multilocularis in the Swedish environment should focus in field habitats where Mi. agrestis and Ar. amphibius are abundant.

Toxoplasma gondii is a ubiquitous apicomplexan parasite that causes toxoplasmosis, a cosmopolitan zoonosis responsible for abortion and congenital malformation in animals and humans. Pigs can be a reservoir for T. gondii and act as one of the sources for parasite transmission to humans. Currently, there are no data about T. gondii infection in any animal in Benin. After the report of several cases of abortions and reproductive problems in pigs in several livestock farms in the southern region of Benin, this study was carried out to investigate the occurrence of this zoonotic parasite in pigs. A total of 184 pig serum samples have been collected in two municipalities and sent to the laboratory for the detection of anti-T. gondii IgG antibodies by ELISA indirect method. The results showed the presence of anti-Toxoplasma gondii IgG in 23% (IC95 = 22.56–23.44) of pigs (42/184). Age, sex, and race did not seem to affect the frequency of this infection. Moreover, reproductive failure has been reported on many farms. These were cases of stillbirths in 40% of farms followed by neonatal mortality (36%) and abortion cases which were frequently observed in 27% of farms. T. gondii is present in pigs from south Benin and could be responsible for reported abortions in the areas. In addition, the raw and undercook meat of pigs could be important source of Toxoplasma gondii infection in humans from south Benin

AbstractTrichinellosis, which is caused by nematodes of the genus Trichinella, is one of the most important zoonotic parasite diseases in the world. A rapid and sensitive immunochromatographic strip (ICS) based on Eu (III) nanoparticles (EuNPs) was developed for the detection of Trichinella spiralis (T. spiralis) infection in pigs. T. spiralis muscle larvae excretory secretory or preadult worm excretory secretory (ML-ES or PAW-ES) antigens were conjugated with EuNPs probes to capture T. spiralis-specific antibodies in pig sera, after which the complex bound to mouse anti-pig IgG deposited on the test line (T-line), producing a fluorescent signal. In the pigs infected with 100, 1000 and 10 000 ML, seroconversion was first detectable for the EuNPs-ML-ES ICS at 30, 25 and 21 days post-infection (dpi) and for the EuNPs-PAW-ES ICS at 25, 21 and 17 dpi. These results show that EuNPs-PAW-ES ICS detects anti-Trichinella IgG in pigs 4–5 days earlier that test using ML-ES antigens. Our ICS have no cross reaction with other parasite infection sera. Furthermore, the detection process could be completed in 10 min. This study indicated that our ICS can be used for the detection of the circulating antibodies in early T. spiralis infection and provide a novel method for on-site detection of T. spiralis infection in pigs.
