“…has been considered one of the most frequent intestinal parasites of dogs [ 6 ]. Not only A. caninum but also different Ancylostoma species are involved in human infection mainly cutaneous larva migrans [ 50 ]. Eosinophilic enteritis and unexplained abdominal pain with peripheral eosinophilia are other manifestation of A. caninum infection in humans.…”

Aim:This work aimed to study the role played by dogs in transmitting zoonotic enteric parasites to humans in Egypt and to analyze the risk factors associated with the occurrence of such infection in dogs. Serodiagnosis of anti-Toxocara immunoglobulin G (IgG) antibodies among human beings as well as analyzing risk factors predispose to Toxocara canis infection in human beings are another objectives of this study.Materials and Methods:From June to December 2013, a total of 130 fecal samples from 4 dog populations (Military, nomadic and domiciled dogs from rural and high standard districts) and 150 stool samples of 6 occupational groups were examined for the presence of enteric parasitic infection. Moreover, 150 serum samples were collected from humans from whom stool samples were collected and examined for the presence of anti-T. canis antibodies.Results:Enteric parasites were detected in 30% of fecal samples from 4 dog populations in Egypt. High infectivity had been reported in nomadic dogs (63.33%) (Crude odds ratios [COR]=67.36, 95% confidence interval [CI]=8.09-560.8, p<0.000), followed by domiciled dogs from rural areas (40%) (COR=26, 95% CI=3.14-215.54, p=0.003), domiciled dogs from high standard areas (23.33%) (COR=11.87, 95% CI=1.37-102.69, p=0.025) and military dogs (2.5%). Twelve species of enteric parasites were identified, Ancylostomatidae (6.15%), T. canis and Cryptosporidium spp. (5.38%, each), Heterophyes spp. (3.85%), Toxocara leonina and Blastocystis spp. (3.07%), Taenidae eggs (2.31%), Hymenolepis diminuta (1.54%) and Entamoeba canis, Cyclospora cayetanensis, and Paragonimus spp. (0.77%, each). Univariate logestic regression revealed significant association of age (COR=4.73, 95% CI=2.13-10.53, p<0.000), gender (COR=2.63, 95% CI=1.22-5.68, p<0.014), housing system (COR=5.10, 95% CI=2.04-12.75), p<0.000) with enteric parasitic infection in dogs. However, breeds (COR=6.91, 95% CI=0.88-54.52, p=0.067) and type of feeding (COR ranged from 3.5 to 7.62, p>0.05) did not seem to have a significant association among the examined dogs. Enteric parasitic infection was reported in 31/150 human stools (20.67%). Students were the most affected groups (37.14%), followed by nomadic people (24%), house wives (20%), house guarders and military workers (12%, each), and employees (10%). The identified parasites were Cryptosporidium spp. (9.33%), Ascaris lumbercoides (3.33%), Heterophyes spp. and Ancylostoma spp. (2.66%, each) and Paragonimus spp. and Hymenolepis nana (1.33%, each). Toxocara IgG antibodies were detected in 36/150 (24%) serum samples investigated. Toxocara IgG antibodies were more prevalent in males (26.66%) than females (20%). Seroprevalence was highest (17/35, 48.57%) in 7-15 years old (COR=6.93, 95% CI=1.75-27.43, p=0.006). Seroprevalence values for T. canis antibodies were higher in those; raising dogs (29.85%), eating raw vegetables (25.21%) and not washing hands before meals (25.45%). T. canis antibodies were detected in 25% of those contacted with soil compared to 30% of those did not. Students w...

“…Besides A. caninum , which is one of the most pathogenic species for dogs, larvae and adults of different Ancylostoma species are involved in human infections. Cutaneous larva migrans or creeping eruption (Velho et al., 2003) is the most common of them. In Brazil, reliable epidemiological data about CLM in native population is scarce, but a population‐based study (Heukelbach et al., 2004) demonstrated that CLM is endemic in a deprived community.…”

Coprological examination was used to estimate the prevalence of gastrointestinal parasites in stray and domiciled dogs from Botucatu, São Paulo State, Brazil. Risk factors for dog infection were assessed in relation to demographic, husbandry and management data. The dog owners completed a questionnaire survey on some aspects of dog parasitism such as parasite species, mechanisms of infection, awareness of zoonotic diseases and history of anthelmintic usage. Parasites were found in the faeces of 138 dogs, with an overall prevalence of 54.3%. Dogs harbouring one parasite were more common (31.4%) than those harbouring two (18.5%), three (3.2%) or four (1.2%). The following parasites and their respective frequencies were detected: Ancylostoma (37.8%), Giardia (16.9%), Toxocara canis (8.7%), Trichuris vulpis (7.1%), Dipylidium caninum (2.4%), Isospora (3.5%), Cryptosporidium (3.1%) and Sarcocystis (2.7%). Stray dogs were found more likely to be poliparasitized (P<0.01) and presented higher prevalence of Ancylostoma, T. canis and Giardia (P<0.01) than domiciled ones. Toxocara canis was detected more frequently in dogs with <6 months of age (P<0.05) and no effect of sex or breed could be observed (P>0.05). Except for Ancylostoma, that showed a significantly higher prevalence in dogs living in a multi-dog household (P<0.01), parasite prevalences were similar in single- and multi-dog household. The answers of dog owners to the questionnaire showed that the majority does not know the species of dog intestinal parasites, the mechanisms of transmission, the risk factors for zoonotic infections, and specific prophylactic measures. The predominance of zoonotic species in dogs in the studied region, associated with the elevated degree of misinformation of the owners, indicates that the risk of zoonotic infection by canine intestinal parasite may be high, even in one of the most developed regions of Brazil.

“…The larvae penetrate the human’s (the accidental host) skin on direct contact and secrete proteases and hyaluronidases to ease their migration and penetration through the epidermis [ 8 , 20 ]. However, the larvae of species such as Ancylostoma braziliense are incapable of attaining the dermis as they lack specific collagenases [ 9 , 21 ]; hence, they wander in the epidermis, producing the pathognomonic serpiginous tracks [ 1 , 22 ].…”

BackgroundCutaneous larva migrans is a neglected zoonotic helminthic disease which is paradoxically underreported in low-income and middle-income countries from where a majority of the cases emanate. It presents as migratory, raised, erythematous serpentine lesions, responsive to treatment with antihelminthics. It is common in children, but rare in babies. We report an unusual case of cutaneous larva migrans in a Cameroonian baby.Case presentationWe report the case of a 9-month-old Cameroonian baby girl, whose mother had the habit of drying the child’s clothes on the grass in her courtyard. The child was brought to our hospital after she developed itchy, snake-like, slowly progressing lesions on her abdomen and chest. An examination revealed multiple raised serpentine and erythematous skin lesions consistent with cutaneous larva migrans which subsided on antihelminthic and antihistaminic therapy.ConclusionsCutaneous larva migrans is an endemic disease with predilection for poor and vulnerable persons. Preventive efforts such as wearing of slippers, usage of drying lines, and deworming of pets are crucial in preventing the occurrence of this disease and should be encouraged.
