          Abstract

          Resumen Introducción. Los perros representan un potencial riesgo para la salud pública debido a que transmiten infecciones parasitarias al hombre. Objetivo. Estimar la frecuencia y determinar los factores asociados a la presencia de huevos de nematodos intestinales en heces de perros recolectadas en parques públicos de Mérida, Yucatán, México. Materiales y métodos. Se analizaron 100 muestras de heces de perros recolectadas en 20 parques públicos de dos zonas de la ciudad. Las muestras se procesaron mediante las técnicas de flotación centrifugada y de McMaster para confirmar la presencia de huevos de nematodos intestinales y cuantificarlos por gramo de heces. Se determinaron los factores asociados a la presencia de los huevos mediante un análisis univariado de χ2. Resultados. Se encontró una frecuencia de 11 %. Se identificaron huevos de tres especies de parásitos y Ancylostoma caninum fue el más frecuente (10 %), seguido por Toxocara canis (1 %) y Trichuris vulpis (1 %). La mayoría de las muestras positivas presentaba infección con un nematodo intestinal únicamente (10 %) y solo el 1 % resultó positivo para infección mixta por A. caninum y T. vulpis. La presencia de perros sin dueño en los parques públicos fue el factor asociado (p=0,046) con un mayor número de heces positivas para huevos de nematodos intestinales. Conclusiones. En los parques de la ciudad se encontraron heces de perros con huevos de nematodos intestinales con potencial zoonótico; la probabilidad de que las muestras fueran positivas fue mayor en los parques con presencia de perros sin dueño.

          Abstract Introduction: Dogs represent a potential public health risk because of the natural transmission of zoonotic parasitic infections. Objective: To estimate the frequency and to determine factors associated with the presence of intestinal nematode eggs in dog feces collected in public parks of Mérida,Yucatán, México. Materials and methods: A total of 100 dog fecal samples collected from 20 public parks in two areas of Mérida were analyzed. Samples were processed by the centrifugation-flotation and the McMaster techniques to confirm the presence and to quantify the excretion of intestinal nematode eggs per gram of feces. The factors associated with the presence of nematode eggs were identified using the chi square univariate analysis. Results: We found an 11% frequency of fecal samples positive for intestinal nematode eggs. Eggs of three species of parasites were identified: Ancylostoma caninum was the most common (10%), followed by Toxocara canis (10%), and Trichuris vulpis (1%). Most positive samples were infected with only one intestinal nematode (10%), and only 1 % was positive for a mixed infection by A. caninum and T. vulpis. The presence of stray dogs in public parks was an associated factor (p=0.046) with a higher number of fecal samples positive for intestinal nematode eggs. Conclusions: The frequency of intestinal nematodes in dog feces with zoonotic potential was high in parks of Mérida, Yucatán, México; samples from parks where there were stray dogs had a higher possibility of being positive.

          Hookworms of dogs and cats as agents of cutaneous larva migrans.

          Dogs and cats are hosts to hookworms that may cause zoonotic disease, most notably, cutaneous larva migrans. Ancylostoma braziliense is most often implicated in dermatological lesions, and Ancylostoma caninum has been associated with eosinophilic enteritis and suggested as a possible cause of diffuse unilateral subacute neuroretinitis in humans. Other manifestations include eosinophilic pneumonitis, localized myositis, folliculitis, erythema multiforme, or ophthalmological manifestations. Ancylostoma eggs are morphologically indistinguishable, which complicates epidemiological studies. Surveys of dermatologists, gastroenterologists, and ophthalmologists would help to define the incidence of these zoonotic infections. Improved diagnostic tests are needed to identify the causative species involved and understand the epidemiology of hookworm disease. This review describes the discovery of the disease, the biology of the agents, and how that biology may impact disease. Copyright (c) 2010 Elsevier Ltd. All rights reserved.

            Pet roundworms and hookworms: A continuing need for global worming

            Ascarids and ancylostomatids are the most important parasites affecting dogs and cats worldwide, in terms of diffusion and risk for animal and human health. Different misconceptions have led the general public and pet owners to minimize the importance of these intestinal worms. A low grade of interest is also registered among veterinary professions, although there is a significant merit in keeping our guard up against these parasites. This article reviews current knowledge of ascarids and ancylostomatids, with a special focus on pathogenicity, epidemiology and control methods in veterinary and human medicine.

              Epidemiological and clinical characteristics of hookworm-related cutaneous larva migrans.

              Hookworm-related cutaneous larva migrans is caused by the migration of animal hookworm larvae in the human skin. The disease mainly occurs in resource-poor communities in the developing world, but it is also reported sporadically in high-income countries and in tourists who have visited the tropics. Diagnosis is made clinically in the presence of a linear serpiginous track moving forward in the skin, associated with itching and a history of exposure. Itching is typically very intense and can prevent patients from sleeping. Bacterial superinfection occurs as a result of scratching. Treatment is based on oral drugs (albendazole or ivermectin) or the topical application of tiabendazole. To control hookworm-related cutaneous larva migrans at the community level, regular treatment of dogs and cats with anthelmintic drugs is necessary, but this is seldom feasible in resource-poor settings. Animals should be banned from beaches and playgrounds. For protection at the individual level, unprotected skin should not come into contact with possibly contaminated soil.
