| detection of toxocara eggs in contaminated soil from various public places of chennai city and detailed correlation with literature. | toxocarosis is one of the most prevalent human helminthosis caused by larvae of toxocara canis and toxocara cati, the most widely distributed nematode parasites of dogs and cats respectively. soil is considered as the principal source of transmission of toxocara infection to human beings. with increasing population of dogs and cats, soil contamination with ova or eggs of toxocara can be detected in public and private locations of city backyards, playgrounds, streets, sand pits and so on, regardl ... | 2014 | 24808647 |
| characterization of excretory-secretory antigens of adult toxocara canis by western blotting. | toxocara canis is one of the most common helminth worm of dogs which continues to stimulate both public health concern alongside the higher scientific interest. it may cause visceral and ocular damage in humans especially in children. the identification of specific antigens of t. canis is important so as to develop better diagnostic techniques. excretory-secretory (es) antigens were prepared by culturing the adult t. canis worms in rpmi 1640 medium without serum supplementation followed by ammon ... | 2014 | 24808645 |
| neurotoxocarosis: marked preference of toxocara canis for the cerebrum and t. cati for the cerebellum in the paratenic model host mouse. | infective larvae of the worldwide occurring zoonotic roundworm t. canis exhibit a marked affinity to the nervous tissues of paratenic hosts. in humans, most cases of neurotoxocarosis are considered to be caused by larvae of t. canis as t. cati larvae have rarely been found in the cns in previous studies. however, direct comparison of studies is difficult as larval migration depends on a variety of factors including mouse strains and inoculation doses. therefore, the present study aims to provide ... | 2014 | 24754900 |
| risk of infection by the consumption of liver of chickens inoculated with low doses of toxocara canis eggs. | experimental studies and registries of cases of human toxocariasis have shown that the consumption of raw or undercooked offal of the paratenic host of toxocara canis may pose a risk of infection. thus, we evaluated the risk of infection due to the consumption of liver of chickens inoculated with different doses of embryonated t. canis eggs. doses were 5-100 times smaller than the ones previously employed in this type of study. groups of five chickens were inoculated with 5000 (control), 1000, 5 ... | 2014 | 24746238 |

| a tick-borne segmented rna virus contains genome segments derived from unsegmented viral ancestors. | although segmented and unsegmented rna viruses are commonplace, the evolutionary links between these two very different forms of genome organization are unclear. we report the discovery and characterization of a tick-borne virus--jingmen tick virus (jmtv)--that reveals an unexpected connection between segmented and unsegmented rna viruses. the jmtv genome comprises four segments, two of which are related to the nonstructural protein genes of the genus flavivirus (family flaviviridae), whereas th ... | 2014 | 24753611 |
| dogs, cats, parasites, and humans in brazil: opening the black box. | dogs and cats in brazil serve as primary hosts for a considerable number of parasites, which may affect their health and wellbeing. these may include endoparasites (e.g., protozoa, cestodes, trematodes, and nematodes) and ectoparasites (i.e., fleas, lice, mites, and ticks). while some dog and cat parasites are highly host-specific (e.g., aelurostrongylus abstrusus and felicola subrostratus for cats, and angiostrongylus vasorum and trichodectes canis for dogs), others may easily switch to other h ... | 2014 | 24423244 |
| characterization of the ca2+-gated and voltage-dependent k+-channel slo-1 of nematodes and its interaction with emodepside. | the cyclooctadepsipeptide emodepside and its parent compound pf1022a are broad-spectrum nematicidal drugs which are able to eliminate nematodes resistant to other anthelmintics. the mode of action of cyclooctadepsipeptides is only partially understood, but involves the latrophilin lat-1 receptor and the voltage- and calcium-activated potassium channel slo-1. genetic evidence suggests that emodepside exerts its anthelmintic activity predominantly through slo-1. indeed, slo-1 deficient caenorhabdi ... | 2014 | 25521608 |
| serological detection of circulating angiostrongylus vasorum antigen and specific antibodies in dogs from central and northern italy. | the most frequently employed method for the diagnosis of angiostrongylus vasorum in dogs is the detection of first stage larvae (l1) in faeces. the sensitivity of coproscopy, however, is limited in case of low parasite load, intermittent larval excretion, and during pre-patency. an epidemiological survey on dogs was conducted applying serological methods in two italian regions where angiostrongylosis is endemic in foxes. 265 dog serum samples from tuscany (central italy - site a) and 447 from li ... | 2013 | 23182301 |
