*  Cerebral toxocariasis: Silent progression to neurogenerative disorders?
Toxocara canis and T. cati are highly prevalent nematode infections of the intestines of dogs and cats. In paratenic hosts, larvae do not mature in the intestine but instead migrate through the somatic tissues and organs of the body. The presence of these migrating larvae can contribute to pathology. Toxocara larvae can invade the brains of humans, and while case descriptions of cerebral toxocariasis are historically rare, improved diagnosis and greater awareness have contributed to increased detection. Despite this, cerebral or neurological toxocariasis (NT) remains a poorly understood phenomenon. Furthermore, our understanding of cognitive deficits due to toxocariasis in human populations remains particularly deficient. Recent data describe an enhanced expression of biomarkers associated with brain injury, such as GFAP, AβPP, transforming growth factor β1 (TGF-β1), NF-L, S100B, tTG, and p-tau, in mice ...
*  Psychology of Medicine: Toxocariasis
Physiological reactions to Toxocara infection depend on the hostâ s immune response and the parasitic load. Most cases of Toxocara infection are asymptomatic, especially in adults. When symptoms do occur, they are the result of migration of second stage Toxocara larvae through the body.. Covert toxocariasis is the least serious of the three syndromes and is believed to be due to chronic exposure. Signs and symptoms of covert toxocariasis are coughing, fever, abdominal pain, headaches, and changes in behavior and ability to sleep. Upon medical examination, wheezing, hepatomegaly, and lymphadenitis are often noted.. High parasitic loads or repeated infection can lead to visceral larva migrans (VLM). VLM is primarily diagnosed in young children, because they are more prone to exposure and ingestion of infective eggs. Toxocara infection commonly resolves itself within weeks, but chronic eosinophilia may result. In VLM, larvae migration incites ...

LOPEZ, María de los Ángeles et al. Toxocara canis and bronchial asthma. Medicina (B. Aires) [online]. 2010, vol.70, n.1, pp. 75-78. ISSN 1669-9106.. In order to evaluate the association between the infection by Toxocara canis and the symptoms of asthma in children from a subtropical region with high prevalence of toxocariasis, 47 asthmatic children and 53 non-asthmatics as a control group were studied. A complete physical examination was performed and clinical and epidemiological data were registered. In asthmatic children the frequency and severity of symptoms were classified in grades I to IV. The presence of anti-Toxocara canis antibodies in both groups was evaluated employing a solid phase ELISA method with excretion/secretion antigens, and total Ig E was also measured. Results showed a total seropositivity of 55%, 57.4% in children with asthma and 52.8% in the control group. Among asthmatics with severe symptoms (grade II, III and IV), there was a 67.7% of ...
*  Eosinophilic folliculitis in a Caucasian patient: association with toxocariasis? - Semantic Scholar
Sterile eosinophilic folliculitis, a clinical entity first described by Ofuji in 1970, is a rather rare skin disorder, in particular in the non-Asian population. We report the first case of eosinophilic folliculitis associated with toxocariasis in a Caucasian patient. Topical and systemic anti-inflammatory and antiphlogistic therapy along with systemic antihelminthic treatment resulted in complete remission of the skin lesions. In addition, there was a marked decrease of antibodies to Toxocara antigens in the patient's serum following antihelminthic therapy. Given that (I) some cases of eosinophilic folliculitis have been reported which were associated with infestation with metazoan parasites; (2) infestations with the roundworm Toxocara canis are known to induce eosinophilic reactions in some tissues; and (3) therapy-induced remission of eosinophilic folliculitis was accompanied by a decrease of Toxocara-directed antibodies in the patient's serum, we propose that there is ...

With the aim of estimating the incidence of infection by Toxocara among residents in the outskirts of Campinas (State of São Paulo, Brazil) two serological surveys, using ELISA anti-Toxocara tests, were performed in January 1999 and January 2000, involving, respectively, 138 and 115 individuals, 75 of which examined in both occasions. Among this group 67 individuals did not show the presence of anti-Toxocara antibodies in 1999, and 12 presented seroconversion in the second survey, revealing an annual incidence rate of 17.9 ...

Human toxocariasis is a helminthozoonosis due to the migration of Toxocara species larvae through human organism. Humans become infected by ingesting either embryonated eggs from soil (geophagia, pica), dirty hands or raw vegetables, or larvae from undercooked giblets. The diagnosis relies upon sensitive immunological methods (ELISA or Western-Blot) which use Toxocara excretory-secretory antigens. Seroprevalence is high in developing as well as developed countries, especially in rural areas, and also in some tropical islands. Here we present the case of a pre-school child, raised in a rural environment, diagnosed with toxocariasis, that was iniatially manifested as acute eosinophilic leukemia, with no liver damage, that was cured 7 years later, after numerous courses of Albendazole throughout the years ...
*  Q&A: The Dogs Today Think Tank: Eye of the storm
There are, I am afraid, elements of truth in your sister's assertion. I think that she is thinking of ocular larva migrans when she talks about you running the risk of going blind, but it is not contracted directly across the eye from a dog's tongue. This is a rare complication of migrating Toxocara canis larvae within the body reaching the eyes.. If a dog has an active roundworm Toxocara canis burden, he or she will be passing T canis eggs in his or her faeces. These eggs are invisible to the naked eye, which is why routine preventative treatment for roundworms is recommended. After a few days in the environment, the eggs mature and became infective - if they are then accidentally swallowed by a person, larvae develop and can migrate through tissues, causing an inflammatory reaction. In rare cases, organs such as the liver or lungs may be damaged, and the larvae can affect vision or even cause blindness if they reach the eyes.. Simple personal hygiene measures such as ...
*  Toxocara cati - Wikipedia
Toxocara cati, also known as the feline roundworm, is parasite of cats and other felids. It is one of the most common nematodes of cats, infecting both wild and domestic felids worldwide. Adult worms are localised in the gut of the host. In adult cats, the infection - which is called toxocariasis - is usually asymptomatic. However, massive infection in juvenile cats can be fatal. Feline roundworms are brownish-yellow to cream colored to pink and may be up to 10 cm in length. Adults have short, wide cervical alae giving their anterior ends the distinct appearance of an arrow (hence their name, toxo, meaning arrow, and cara meaning head). Eggs are pitted ovals with a width of 65 μm and a length of about 75 μm making them invisible to the human eye. The larvae are so small that they are easily transmitted from an adult female to her nursing kittens through her milk. Pregnant women who become infected with T. cati can pass the infection on to their baby who may have develop ...

Human toxocariasis is usually contracted by exposure to contaminated soil. This disease is rarely transmitted by raw meat or giblets of paratenic animals, such as chickens, lambs, or cows. We present a case of isolated cerebral toxocariasis presumably caused by the consumption of raw duck liver. This 55-year-old woman had sudden-onset hemiparesis of the right leg, eosinophilia of 30%, and markedly elevated total serum IgE levels. Magnetic resonance imaging demonstrated multiple cerebral hyperintense lesions on T2-weighed images. Tests for antibodies to Toxocara in serum and cerebrospinal fluid yielded highly positive results. Repeated courses of albendazole and corticosteroids led to significant clinical improvement.
*  Knowledge gaps in the epidemiology of Toxocara: the enigma remains | Cambridge Medicine
Some parasites seem to have a Cinderella status. Down in the basement of the ugly stepmother's house, they are working away, busily infecting many hosts but there is no handsome prince, in the form of generous research funding, to bring them to the ball. Despite the most welcome initiatives concerning Neglected Tropical Diseases (NTDs), human toxocariasis, with its worldwide distribution, remains strangely ignored. Why is this so? There is no doubt that its multiple routes of transmission to hosts, both domestic and feral, its cryptic disease picture in humans, problems with diagnosis and treatment and its widespread environmental contamination, all contribute to the challenge of researching this enigmatic helminth and to devising appropriate preventative and control measures.. However, that is not the full story. The number of investigators who make Toxocara their main focus is diminishing. Tragically, Huw Smith, of the Scottish Parasite Diagnostic Laboratory, passed away ...
*  Neglected tropical diseases - Wikipedia
Neglected tropical diseases (NTDs) are a diverse group of tropical infections which are especially common in low-income populations in developing regions of Africa, Asia, and the Americas. They are caused by a variety of pathogens such as viruses, bacteria, protozoa and helminths. These diseases are contrasted with the big three diseases (HIV/AIDS, tuberculosis, and malaria), which generally receive greater treatment and research funding. In sub-Saharan Africa, the effect of these diseases as a group is comparable to malaria and tuberculosis. NTD co-infection can also make HIV/AIDS and tuberculosis more deadly. In some cases, the treatments are relatively inexpensive. For example, the treatment for schistosomiasis is US$0.20 per child per year. Nevertheless, in 2010 it was estimated that control of neglected diseases would require funding of between US$2 billion and US$3 billion over the subsequent five to seven years. Some pharmaceutical companies have committed to donating all the drug ...

Dog roundworm. Coloured scanning electron micrograph (SEM) showing the head of a dog roundworm (Toxocara canis). This is a dog parasite whose eggs are found in dog faeces. Humans, often children, can become infected with the eggs (which is known as toxocariasis) when coming into contact with an infested dog or contaminated soil. The swallowed eggs hatch in the intestines and the larvae then migrate to organs such as the liver, lungs, brain and eyes. Symptoms include asthma, seizures, pneumonia and blindness.

*  fish-pedicure-treatment: Animals as sentinels for disease
This week's intellectual exchange featured guest lecturers Dr. Larry Glickman and Dr. William Stokes. Dr. Larry Glickman is a veterinarian and epidemiologist. He presented on some of his research on surveillance of companion animals as an indicator of disease. One case study he presented was on the transmission of Toxocara canis, or Dog Roundworm infection. The eggs of Toxocara are present in the environment and are extremely resilient, lasting for years without a host. Dogs are a natural host for Toxocara. By our exposure to dogs, people (especially young children), are at risk for acquiring the parasite. As humans are an unnatural host for Toxocara, we can experience debilitating symptoms as a result, including respiratory and eye health issues. Over twenty million children are infected at any one time. Although most cases are asymptomatic, 3000 cases of blindness are caused yearly due to the parasite traveling to the eye. In West Africa, Toxocara is also a serious issue. Due to the high ...
