Toxocariasis, one of a group of parasitic diseases known as neglected parasitic infections, is a disease caused by the larvae of two species of Toxocara roundworms, Toxocara canis, from dogs, and less commonly Toxocara cati, from cats. Although most infected individuals are asymptomatic, clinical manifestations may include fever, fatigue, coughing, wheezing, or abdominal pain (visceral toxocariasis) or vision loss, retina damage, or eye inflammation (ocular toxocariasis). To assess U.S. pediatrician knowledge of toxocariasis, we conducted an electronic survey of American Academy of Pediatrics members...

Worldwide, Toxocara canis is an important zoonotic nematode of public health concern. This soil-transmitted helminth causes visceral larva and ocular larva migrans in paratenic hosts. The detection of T. canis larva migrans is complicated because current immunological tests detect only IgG antibodies, which can cross-react with antigens from other parasites and cannot distinguish between the past and present infection. Analysis of antigen release and antibody production could help improve the detection of larva migrans...

Parasitic nematodes of the genus Toxocara are socioeconomically important zoonotic pathogens. These parasites are usually directly transmitted to the human host via the faecal-oral route and can cause toxocariasis and associated complications, including allergic and neurological disorders. Although tens of millions of people are estimated to be exposed to or infected with Toxocara spp, global epidemiological information on the relationship between seropositivity and toxocariasis is limited. Recent findings suggest that the effect of toxocariasis on human health is increasing in some countries...

BACKGROUND: Toxocariasis is a prevalent zoonosis disease caused by the closely related nematode species Toxocara canis and Toxocara cati which parasitise Canidae and Felidae respectively. In paratenic hosts, larvae of these worms cause multiple organ damage. However, how these paratenic hosts response to these worms and whether any common biomarker can be applied for diagnosis are still unclear. METHODS: Excreted/secreted (E/S) antigens were prepared by culture of T...

Toxocariasis is one of the most common neglected infections of poverty in the U.S. with a reported National Health and Nutrition Examination Survey (NHANES) III (1988-1994) seroprevalence of 13.9% based on enzyme immunoassay testing. We reviewed NHANES data from 2011-2014 to assess current levels. Sera collected from NHANES 2011-2014 participants six years and older were tested for exposure using rTc-CTL-1 antigen, a more sensitive and specific recombinant antigen for IgG antibodies for Toxocara spp. These results were subdivided into children (age 6-17) and adults (age ≥ 18) and then compared between various sociodemographic characteristics...

BACKGROUND: Larva migrans syndrome is a food-borne parasitic disease in humans, caused by accidental ingestion of eggs or larvae of ascarid nematodes, namely, Toxocara canis, Toxocara cati, or Ascaris suum, the roundworms commonly found in the intestines of dogs, cats and pigs respectively. When a patient is diagnosed as having larva migrans syndrome, oral-administration of albendazole is recommended, however, the regimen remains controversial worldwide. In Japan, the duration of albendazole administration is longer than those of European and North American countries...

Echinococcus multilocularis, Toxoplasma gondii and Toxocara spp. are foodborne parasites whose eggs or oocysts are spread in the environment via canid or felid faeces. They can cause infections in humans following the raw consumption of contaminated fruit or vegetables. In this study, their occurrence was investigated by quantitative polymerase chain reaction (qPCR) in 254 carnivore faeces deposited in 94 kitchen gardens of northeastern France that were sampled between two and six times from October 2011 to April 2013...

Soil can be a source of human infection by many zoonotic helminth species including Echinococcus multilocularis and Toxocara spp. The prevention of alveolar echinococcosis could be greatly improved through the identification of at-risk areas. Yet very few data are available about the detection of E. multilocularis in soil, while more studies have been reported for Toxocara spp. Identification of soil contamination by E. multilocularis eggs requires the use of specific methods. This study describes the development of a method for the detection of E...

Toxocariasis is a zoonotic disease that occurs when humans are infected by the parasites Toxocara canis or Toxocara cati. Toxocariasis is highly prevalent in tropical areas, but can also be found in industrialized countries, particularly in rural areas. Clinical presentation can range from asymptomatic infection to more severe disease. Diagnosis of toxocariasis is based on suggestive clinical findings, eosinophilia and a positive serological testing. Albendazole represents the first-line treatment, associated with corticosteroids in case of severe disease...

Gastrointestinal (GIT) parasites of domestic cats (Felis catus) not only cause morbidity but are also potential zoonotic agents. The current study aimed at establishing the prevalence of GIT parasites in cats kept by households in Thika region, Kenya. Fecal samples were collected randomly from 103 cats and analyzed for presence of parasites using standard parasitological methods. In descending order, the prevalence of the detected protozoa parasites was Isospora spp. 43.7% (95% CI: 40.4-47%), Cryptosporidium spp...

Keeping of infected dogs as pet results in the potential transmission risk factors for shedding helminthic infections such as toxocariasis. Lack of accurate identification of Toxocara canis eggs in non-dewormed infected pet dogs remains a diagnostic concern among researchers. In this study, dog owners were asked to fill up a questionnaire regarding their pets and their attitude towards the deworming regimen. One hundred faecal samples were collected from pet dogs (Northwest Iran) and were subsequently identified by the ZnSo4 flotation technique, PCR and loop-mediated isothermal amplification (LAMP) assays...

The increasingly urban nature of the population has led many people to choose independent pets, such as cats. This situation has also made it possible for these animals to be abandoned, thus increasing the numbers of cats on the streets and in shelters. These animals can act as a source of infection for other hosts. Between 2014 and 2015, the frequency of gastrointestinal parasites in captive and stray cats in the municipality of Rio de Janeiro was analyzed. Ninety-one fecal samples were collected from captive cats and 172 from stray cats...

[b]Abstract [/b] Dogs serve as the vectors of serious zoonotic parasitic diseases. In the month of May 2012 - 2014, 339 dog faeces samples from seven public sites in Chełmno, a town in northern Poland, were collected and examined to determine the gastrointestinal parasite fauna of dogs. Each faecal sample was dissected with a needle, checked for tapeworm segments and examined for parasite eggs and oocysts using the flotation and decantation method and a modified Baermann technique. Differences were observed in the degree of parasite species occurrence...

BACKGROUND: Cluster headache (CH) is characterized by attacks of severe periorbital pain associated with autonomic symptoms. As with other forms of primary headache, structural lesions should be excluded, particularly if the headache presents with an atypical pattern. CASE: We report a 41-year-old woman who had no previous history of primary headache and showed a poor response to medication for CH. The patient was finally diagnosed as secondary headache with CH feature due to focal myelitis at the cervical level of the spinal cord...
