Hypereosinophillia is a rare clinical entity. It is associated with a wide differential diagnosis including neoplasm, infection, and allergic etiologies. Clinicians should have a well defined approach to hypereosinophilia in order to find treatable causes. We present a case of hypereosinophillia caused by parasitic infection with Toxocara canis. We also review epidemiology, transmission, microb...
Background and Aims: Toxocariasis is a zoonotic parasitic disease with worldwide distribution caused by the larval stage of ascaridoid nematodes of dogs (Toxocara canis) and cats (Toxocara cati). The study was accomplished to determine the sequence variation in ITS2 and COX1 genes within isolates of Toxocara canis. Materials and Methods: Two hundred Stool samples were collected randomly from d...
ABSTRACT Aim: One of the main diagnostic problems of conventional polymerase chain reaction (PCR) is indiscrimination of low parasitic loads in soil samples. The aim of this study is to determine the genetic diversity and identification of Toxocara spp. from public areas soil inferred by loop-mediated isothermal amplification (LAMP) assay. MATERIALS AND METHODS A total of 180 soil samples wer...
Toxocara canis is an intestinal nematode affecting dogs and cats that causes human infestations by ingestion of embryonated eggs excreted in dogs' faeces. Humans are transport hosts, in whom the larvae do not develop to adult worms, but may migrate to various tissues and organs, and survive for several years, giving rise to several clinical symptoms, which include allergy-like presentations. We...
Human toxocariasis is due to the larval stages of the Ascarids Toxocara canis (T. canis) and probably Toxocara catis, common roundworm of dogs and cats respectively. Among the helminthiasis, toxocariasis is one of the most prevalent worldwide, especially in settings where man-soil-dog relationship is particularly close. Even if it tends to be more prevalent in tropical settings, seroprevalence ...
Human infections by Toxocara canis or Toxocara cati larvae are frequent and have a cosmopolitan distribution resulting, sometimes, in the occurrence of visceral larva migrans syndrome. Ingestion of embryonated Toxocara eggs, present in the superficial layers of the soil, represents the most important way for human infection by these ascarids. Therefore, contact with contaminated soil is conside...
OBJECTIVE The aim of the study was to determine the frequency of antibodies to Toxocara in Cuban schoolchildren. METHODS The frequency of antibodies to Toxocara canis was assessed with a commercial enzyme-linked immunosorbent assays kit in school-aged children from two municipalities of Cuba. Univariate analysis and a multivariable logistic regression analysis adjusted for age, sex, municipal...
mopolitan roundworms that infect dogs, especially puppies, and cats. T. canis infection in humans occurs by ingestion of the embryonic eggs, which are shed in the feces of infected dogs. Toxocariasis is manifested in three different syndromes: visceral larva migrans (VLM), ocular larva migrans (OLM), and covert toxocariasis (1, 2). VLM is usually a disease of children 1 to 6 year old, and it ma...
BACKGROUND Toxocariasis is a zoonotic disease that poses a threat to public health worldwide. This disease primarily affects children and is caused by the presence in the digestive tract of a common roundworm of dogs, Toxocara canis, or cats, Toxocara cati. Toxocara is responsible for the presentation of various syndromes in humans depending on the affected organs. METHODS In this study, the ...
CASES of endophthalmitis due to invasion of the eye by migrating larvae of Toxocara canis, the common round worm of the dog, have been reported by Irvine and Irvine (1959), Harris (1961), and Duguid (1961a, b), while five of the 46 cases reported by Wilder (1950) as nematode endophthalmitis were later identified by Nichols (1956) as being caused by Toxocara. Ashton (1960) described four cases o...
