| effects of toxocara larvae on brain cell survival by in vitro model assessment. | neuroinvasive larvae of the common dog and cat roundworms, toxocara canis and toxocara cati, may cause severe neurological and neuropsychological disturbances in humans. despite their pathogenic potential and high prevalence worldwide, little is known about their cell-specific influences and cerebral host-pathogen interactions in neurotoxocarosis. to address this discrepancy, a co-culture system of viable larvae with murine neuronal (cad), oligodendrocytal (bo-1) and microglial (bv-2) cell lines ... | 2015 | 26080924 |
| production of toxocara cati tes-120 recombinant antigen and comparison with its t. canis homolog for serodiagnosis of toxocariasis. | toxocariasis is a cosmopolitan zoonotic disease caused by the infective larvae of toxocara canis and t. cati. diagnosis in humans is usually based on clinical symptoms and serology. immunoglobulin g (igg)-enzyme-linked immunosorbent assay kits using t. canis excretory-secretory (tes) larval antigens are commonly used for serodiagnosis. differences in the antigens of the two toxocara species may influence the diagnostic sensitivity of the test. in this study, t. cati recombinant tes-120 (rtes-120 ... | 2015 | 26033026 |
| field evaluation of a rapid diagnostic test to detect antibodies in human toxocariasis. | human toxocariasis which is caused mainly by the larvae of toxocara canis and toxocara cati, is a worldwide zoonotic disease that can be a potentially serious human infection. the enzyme-linked immunosorbent assay (elisa) using t. canis excretory-secretory (tes) antigens harvested from t. canis larvae is currently the serological test for confirming toxocariasis. an alternative to producing large amounts of toxocara tes and improved diagnosis for toxocariasis is through the development of highly ... | 2015 | 25910623 |
| enhanced resolution of eosinophilic liver abscess associated with toxocariasis by albendazole treatment. | visceral larva migrans, caused by toxocara canis and toxocara cati, has emerged as a significant cause of eosinophilic liver abscess (ela). differentiation of ela associated with toxocariasis (ela-t) from metastasis or primary liver malignancy is sometimes difficult. however, the role of albendazole treatment remains uncertain in this condition. the aim of this study was to evaluate whether albendazole can enhance the radiologic resolution of ela-t. | 2015 | 25896156 |
| microarray gene expression analysis reveals major differences between toxocara canis and toxocara cati neurotoxocarosis and involvement of t. canis in lipid biosynthetic processes. | toxocara canis and toxocara cati are globally occurring intestinal nematodes of dogs and cats with a high zoonotic potential. migrating larvae in the cns of paratenic hosts, including humans, may cause neurotoxocarosis resulting in a variety of neurological symptoms. toxocara canis exhibits a stronger affinity to the cns than t. cati, causing more severe neurological symptoms in the mouse model. pathomechanisms of neurotoxocarosis as well as host responses towards the respective parasite are mos ... | 2015 | 25843806 |
| epidemiology of human toxocariasis in poland - a review of cases 1978-2009. | toxocariasis is a helminthozoonosis due to the infection of humans with larvae belonging to the toxocara genus. humans become infected as a result of accidental consumption of infected eggs containing third stage larvae (l3) nematodes from toxocara canis or toxocara cati species. toxocariasis was recognized for the first time in the early 1950s, and the first cases of toxocariasis in poland were described a few years later. toxocariasis is clinically classified into several types: classic and in ... | 2015 | 25780823 |
| neurotoxocarosis alters myelin protein gene transcription and expression. | neurotoxocarosis is an infection of the central nervous system caused by migrating larvae of the common dog and cat roundworms (toxocara canis and toxocara cati), which are zoonotic agents. as these parasites are prevalent worldwide and neuropathological and molecular investigations on neurotoxocarosis are scare, this study aims to characterise nerve fibre demyelination associated with neurotoxocarosis on a molecular level. transcription of eight myelin-associated genes (cnp, mag, mbp, mog, mrf- ... | 2015 | 25773181 |
| behavioural changes and muscle strength in rattus norvegicus experimentally infected with toxocara cati and t. canis. | toxocara canis and toxocara cati are nematode parasites in dogs and cats, respectively, transmitted by ingestion of embryonated eggs, transmammary and transplacental (t. canis) routes and paratenic host predation. many parasites use mechanisms that change the behaviour of their hosts to ensure continued transmission. several researchers have demonstrated behavioural changes in mouse models as paratenic hosts for t. canis. however, there have been no studies on behavioural changes in laboratory r ... | 2015 | 24725503 |
