risk factors for toxocara spp. seroprevalence and its association with atopy and asthma phenotypes in school-age children in a small town and semi-rural areas of northeast brazil.toxocara canis, toxocara cati, are roundworms that live in the intestines of dogs and cats, respectively, and are predominantly agents of human toxocariasis. studies have suggested that toxocara spp. seroprevalence increases levels of total and aeroallergen-specific ige (sige), asthma prevalence and asthma morbidity. nevertheless, other work reported a negative association between toxocara spp. seropositivity with skin hypersensititity and a positive association with sige. the objective of the p ...201627080332
gastrointestinal parasites of cats in brazil: frequency and zoonotic risk.gastrointestinal helminths are considered to be the most common parasites affecting cats worldwide. correct diagnosis of these parasites in animals living in urban areas is pivotal, especially considering the zoonotic potential of some species (e.g. ancylostoma sp. and toxocara sp.). in this study, a copromicroscopic survey was conducted using fecal samples (n = 173) from domestic cats living in the northeastern region of brazil. samples were examined through the flotac technique and the overall ...201627096530
eosinophilic myocarditis due to toxocariasis: not a rare cause.myocarditis is a clinically important disease because of the high mortality. from the perspective of treatment strategy, eosinophilic myocarditis should be distinguished from other types of myocarditis. toxocariasis, caused by toxocara canis or toxocara cati, is known as a cause of eosinophilic myocarditis but is considered rare. as it is an unpopular disease, eosinophilic myocarditis due to toxocariasis may be underdiagnosed. we experienced two cases of eosinophilic myocarditis due to toxocaria ...201627123346
seroepidemiology of human toxocara and ascaris infections in the netherlands.toxocara canis, toxocara cati and ascaris suum are worldwide-distributed zoonotic roundworms of dogs, cats and pigs, respectively. the epidemiology of these parasites in developed countries is largely unclear. two countrywide cross-sectional serosurveys were therefore conducted in the netherlands in 1995/1996 and 2006/2007 to investigate the prevalence, trends and risk factors for human toxocara and ascaris infections in the general population. the netherlands is characterized by high pig produc ...201627234034
chronic polyarthritis as isolated manifestation of toxocariasis.human toxocariasis is a parasitic zoonosis mainly caused by toxocara canis or toxocara cati and is acquired by ingestion of the parasite's embryonated eggs. arthralgia and/or arthritis were reported in up to 17% of the cases, generally with acute duration (less than 6 weeks). however, to our knowledge, chronic polyarthritis, as the isolated presentation of toxocara infection, was not reported. one of the 5809 patients that was followed up at our service (0.017%) had chronic polyarthritis as the ...201627267534

epidemiological survey of zoonotic helminths in feral cats in gran canaria island (macaronesian archipelago-spain).the presence of zoonotic parasites in feral cats have been widely considered all over the world. in gran canaria (macaronesian archipelago, canary islands, spain) the number of feral cats has grown out of control in urban and rural areas. 48 of felis catus captured in different gran canaria areas were studied. animals were necropsied and several organs were systematically examined in order to collect and identify macroscopic parasites. in addition, coprological tests were done in 28 cats. there ...201627447205
helminth infections and cardiovascular diseases: toxocara species is contributing to the disease.toxocariasis is the clinical term used to describe human infection with either the dog ascarid toxocara canis or the feline ascarid toxocara cati. as with other helminths zoonoses, the infective larvae of these toxocara species cannot mature into adults in the human host. instead, the worms wander through organs and tissues, mainly the liver, lungs, myocardium, kidney and central nervous system, in a vain attempt to find that, which they need to mature into adults. the migration of these immatur ...201727492228
modified method to enhanced recovery of toxocara cati larvae for the purposes of diagnostic and therapeutic.human toxocariasis, extraintestinal-migration of toxocara species, is a worldwide helminthic zoonosis in many places of the undeveloped countries. toxocara cati is one of the common helminths in cats and it is a potentially preventable disease. its diagnosis and treatment depend on the demonstration of specific excretory-secretory toxocara antibodies from toxocara larvae by immunological assays. this study provides a simple manual technique which can be performed in any laboratory for recovering ...201627502936
