••
TL;DR: A consensus of opinions on the diagnosis, treatment, prognosis and prevention of CanL is presented, and a system of four clinical stages, based on clinical signs, clinicopathological abnormalities and serological status is proposed.
526 citations
••
TL;DR: Information on the prevalence, transmission, and control of ovine toxoplasmosis in the last 20 years is reviewed and it is reported that repeat ovine transmission of T. gondii may be more common than previously believed.
387 citations
••
TL;DR: The present review shows that trematodes, similarly as other helminths presenting larval stages living freely in the environment and/or larval Stage parasitic in invertebrates easily affected by climate change as arthropods and molluscs as intermediate hosts, may be largely more susceptible to climate change impact than those helminthiases in whose life cycle such phases are absent or reduced to a minimum.
327 citations
••
TL;DR: There is an urgent need for better monitoring and control of food-borne parasites using new technologies because of inadequate systems for routine diagnosis and monitoring or reporting for many of the zoonotic parasites.
307 citations
••
TL;DR: The global warming projected by the Intergovernmental Panel on Climate Change suggests that warm summers suitable for Dirofilaria transmission in Europe will be the rule in the future decades and if the actual trend of temperature increase continues, filarial infection should spread into previously infection-free areas.
304 citations
••
TL;DR: An overview of each "emerging" vector-borne diseases of pets is presented, and attention should be kept on tick-borne encephalitis, which seems to be increasing in western Europe, as well as flea-borne disease like the fleA-transmitted rickettsiosis.
291 citations
••
TL;DR: Information on prevalence, transmission, diagnosis, and control of porcine toxoplasmosis in the last 20 years (since 1988 when last reviewed by this author) is reviewed.
257 citations
••
TL;DR: The results suggest that these disease agents may be present over a wider geographic area, and thus pose greater animal and public health risks, than is currently recognized.
254 citations
••
TL;DR: The concept ofRefugia is explained, the role of refugia-based approaches to the management of anthelmintic resistance is described and the markers that have been studied as indicators for TSTs are reviewed.
250 citations
••
TL;DR: Investigating whether healthy pets harbour zoonotic parasitic infections and to make an inventory of the interactions between pet-owners and their companion animals in The Netherlands finds close physical contact between owners and their pets is common and poses an increased risk of transmission ofZoonotic pathogens.
244 citations
••
TL;DR: The results of the present study suggest that A. absinthium extracts are a promising alternative to the commercially available anthelmintics for the treatment of GI nematodes of sheep.
••
TL;DR: All the valid species, genotypes and zoonotic subtypes of Cryptosporidium reported in the international literature are included in this paper with respect to the taxonomy, epidemiology, transmission and morphologic-genetic information for each species.
••
TL;DR: There was a significant difference between the different breeding kennels for the occurrence of Cystoisospora, Giardia and T. canis infections, especially in household dogs, where the majority ofGiardia positive samples belonged to the zoonotic assemblage A.
••
TL;DR: Monitoring of GI-nematode infections is desirable in order to focus anthelmintic treatments on those herds with a high larval challenge and associated production losses, and to evaluate the effects of different control approaches in terms of financial benefits for the farmer and sustainability on the long term.
••
TL;DR: Data indicate that intestinal parasites remain a common, important finding in dogs presenting to veterinary practices although in most of the country infection rates in pet dogs appear to be greatly reduced from the level reported from dogs in animal shelters.
••
TL;DR: Examination of changing dynamics of host-parasite interactions at high latitudes is examined to illustrate a framework for approaching understanding, preventing, and mitigating climate change impacts on infectious disease, including zoonoses, in wildlife.
••
TL;DR: It is indicated that A. americanum is involved in the ecology of several disease agents of humans and other animals, and the role of this tick as a vector of these diseases ranges from incidental to significant.
••
TL;DR: Endoparasitism was predominantly a disease of younger animals, with peak prevalence observed almost uniformly in dogs under 6 months old, with the exception of Trichuris with its longer pre-patent period, and in cats less than 18 months old.
••
TL;DR: Investigation of the prevalence of anthelmintic resistance in gastro-intestinal nematodes on cattle farms in Germany, Belgium and Sweden in 2006 and 2007 and results suggest that testing of anesthetic efficacy should be performed more intensively due to possible insufficient efficacy of current drugs are suggested.
••
TL;DR: The new species was distinct from all other Cryptosporidium species as demonstrated by multi-locus analysis of the 3 unlinked loci and was recognized as a new species and is named C. xiaoi.
••
TL;DR: Production-limiting disease outbreaks caused by Haemonchus contortus, Nematodirus battus, Teladorsagia circumcincta and Fasciola hepatica in sheep flocks in south eastern Scotland are described.
••
TL;DR: The findings reported here show that careful examination of variants of the 18S rRNA gene of T. equi and B. caballi is required prior to the development of molecular diagnostic tests to detect these parasites in horses.
••
TL;DR: Fecal sample results supported the suspicion that decreased productivity and diarrhea in cattle experienced in 2002 were the result of GI nematode parasitism and the first report of anthelmintic resistance in American cattle parasites is reported.
••
TL;DR: PCR analysis of serially collected ejaculates indicated that shedding of Leishmania in the semen is intermittent, supporting the notion that L. chagasi may be sexually transmitted from naturally infected dogs to susceptible bitches in the absence of the biological insect vector.
••
TL;DR: It is indicated that capybaras act as amplifier host of R. rickettsii for A. cajennense ticks in Brazil, and rickettsemia capable to cause infection in guinea pigs and ticks is demonstrated.
••
TL;DR: The objective of this review article is to examine the problem of parasite control in the face of parasite drug resistance and to outline some strategies that may be used in parasite control programmes.
••
TL;DR: The relatively high number of lungworm-infected dogs and cats indicate that these parasitic diseases should be considered in differential diagnosis of cases of treatment-resistant respiratory/cardiopulmonary distress.
••
TL;DR: The results suggest that the local rhesus monkeys are a possible source of Blastocystis sp.
••
TL;DR: Data confirm that a potentially significant reservoir of infected dogs is resident in areas where future climatic conditions may support introduction of competent vectors.
••
TL;DR: The findings of the present study indicate that pre-weaned lambs are not an important source of zoonotic Giardia genotypes in Australia but may be anImportant source ofZoonotic Cryptosporidium.
