Objetivo: Avaliar a presença de parasitos em amostras de fezes e de solo colhidas em diferentes áreas no Município de Ituiutaba-MG. Metodologia: Foram visitadas 17 praças e coletadas um total de 85 amostras de fezes, analisadas pelas técnicas parasitológicas de flutuação, formol-éter e sedimentação espontânea. As amostras de solo foram colhidas em 20 locais entre praças e clubes, sendo cinco amostras em cada local. As amostras foram acondicionadas em sacos formando um “pool do local”, e identificadas com data e temperatura do solo e encaminhadas para análise parasitológica. Resultados: Do total de amostras de fezes coletadas 23,5% (20/85) estavam positivas, sendo 68% (15/20) apresentaram formas evolutivas de Ancylostoma spp e 9% das amostras (2/20) continham ovos de Dipylidium caninum e/ou de Toxocara spp. Quanto à presença de protozoários, 9% (2/20) das amostras tinham cistos e/ou trofozoíto de Giardia duodenalis e 4,5% (1/20) apresentaram oocistos de coccídeos. Do total de amostras de solo coletadas, 70% (14/20) dos locais positivaram para formas parasitárias de helmintos, sendo que 78,5% (11/14) apresentaram formas evolutivas de Ancylostoma spp , 64,3% (9/14) de Toxocara spp.,  14,3% (2/14)  Strongyloides stercolaris, 7,2% (1/14) D. caninum ou  Hymenolepis nana ou Spirometra mansonoides. Conclusão: O encontro de formas parasitárias nestes locais destaca a necessidade de ações de promoção em saúde, colocando em prática o conceito de saúde única.

PARASITES fall only roughly into the two categories implied in the title of this discussion. While a few of them are totally dependent upon human hosts, and some are able to develop only in other animals, a majority of the parasites commonly referred to as "parasites of man" are in reality parasites of other animals. In the latter group are such familiar examples as Trichinella, found in rats and many other animals, including pigs; Balantidium and some lesser protozoa of pigs; Toxoplasma, which occurs in many wild and domesticated animals. Trypanosoma cruzi, which is carried by a variety of animals, is the cause of Chagas' disease commonly seen in parts of South America and found recently in a child in Texas. Other examples include Isospora of undetermined hosts, possibly including the dog; Trichostrongylus species that commonly are found in sheep and goats; the small tapeworms, Hymenolepis nana and Hymenolepis diminuta, of rats and mice; and the common dog tapeworm, Dipylidium caninum. There are others whose endemicity in any area depends somewhat on the presence of suitable non-human hosts, and still others that are able to reach maturity in man but are rarely involved in medical problems because infection is acquired only by eating uncooked earthworms and insects. It might be mentioned, as a matter of interest, that occasionally other animals may acquire parasitic diseases from their human associates, as for example dysentery and diarrhea in dogs, caused by Entamoeba histolytica and Strongyloides stercoralis. In all of the above mentioned parasitic infections, diagnosis is usually based on conventional laboratory methods, and both clinical and laboratory workers are generally familiar with the problems presented by them.

Abstract Foliar vegetables contaminated with fecal residues are an important route of transmission of intestinal parasites to humans. The aim of this study was to evaluate the presence of parasitic forms of protozoa and helminths on lettuces (Lactuca sativa) and collard greens (Brassica oleracea) sold in street- and supermarkets in the city of Aparecida de Goiânia, Goiás, Brazil. A total of 30 samples of each vegetable (15 samples from each supermarkets and street markets) was analyzed. All samples were processed by spontaneous sedimentation method and centrifugal flotation. In 45% of the samples, immature forms of intestinal parasites were identified with 66.7% helminths eggs and 33.3% protozoan cysts or oocysts. Significantly more lettuce samples were contaminated with eggs, cysts or oocyst of at least one parasite than collard green samples (U=216; Z=-3.45; P <0.001). The parasitic forms were identified morphologically up to the family level with eggs of Ancylostomatidae, Strongyloididae, Ascarididae and Taeniidae, or oocysts of Eimeriidae, to the genus with Cystoisospora sp. and Toxocara sp., and to the species level with Cystoisospora canis, Dipylidium caninum and Hymenolepis nana. The presence of these infective agents in lettuce and collard green from both street- and supermarkets highlights the high risk of spreading parasites by eating raw vegetables sold in Aparecida de Goiânia.

Parasitic Zoonoses

Abstract Considering the close contact of companion animals and humans, gastrointestinal parasitic zoonoses are very widespread and represent a high risk of transmission with the potential of severe consequences affecting the digestive tract of both humans and other animals. In this study we focused on enteric zoonoses caused by Toxocara canis nematode, Dipylidium caninum tapeworm and Giardia duodenalis protozoa. Our primary aim was to observe Toxocara canis egg excretion within the 27 consecutive days before and after orally treatment (2 Caniverm® tablets) on Day 13 in a naturally infected puppy. An average egg per gram (EPG) of T. canis detected by coprological quantitative McMaster method was 4558.33 and 666.66, before and after treatment, respectively. The percentage of faecal egg count reduction (%FECR) in in vivo Faecal Egg Count Reduction Test (FECRT) has confirmed an 85.37 % efficacy against T. canis. Secondly, the efficacy of Caniverm® against the tapeworm Dipylidium caninum was also determined. No D. caninum proglottides were detected on Day 14. The data showed 100 % effectiveness of the anthelmintic treatment. Metrobactin® 250 mg has been tested as experimental therapy against Giardia duodenalis on Day 3. On day 10, no cysts were observed in the faeces after per os ¼ tablet administration twice a day for 7 days.

AbstractComparative histochemical studies of glycosidase activity were carried out in Clonorchis sinensis, Eurytrema pancreaticum, Fasciola hepatica, Dipylidium caninum, Hymenolepis nana, Ascaris suum, Toxocara canis, Ancylostoma caninum, Trichuris vulpis and Dirofilaria immitis. The enzymes examined were: N-Acetyl-α-Glucosaminidase (Ec 3.2.1.30), α-Glucuronidase (Ec 3.2.1.31) and α-Galactosidase (Ec 3.2.1.23). There were variations in enzyme distribution and intensity among the species and also between trematodes and nematodes; no marked positive reaction for these enzymes occurred in cestodes. In some trematodes, the caeca, especially in the brush border, and the tegument, subtegumental cells and testes, were reactive to the enzymes. In nematodes, although there was variation in reactions among species, N-acetyl-α-glucosaminidase and α-galactosidase were localized in the hypodermis and lateral cords excluding the excretory canal, and coelomocytes, intestinal epithelium and the walls of the reproductive systems.

Objetivo: Determinar la frecuencia de parasitosis intestinal en el Hospital de Emergencias Pediátricas, Lima, Perú. Materiales y métodos: Se realizó un estudio prospectivo y de corte transversal durante mayo y junio de 2003, que incluyó 108 pacientes pediátricos entre 11 meses y 11 años de edad. Se analizó una muestra fecal por individuo mediante tres métodos parasitológicos: Exámen directo, técnica de Faust y la Técnica de Sedimentación Espontánea en Tubo (TSET). Resultados: La frecuencia de parasitosis intestinal fue de 50,9%. El protozoo más frecuente fue Blastocystis hominis (34,3%) seguido de Giardia duodenalis (10,2%). El helminto más frecuente fue Ascaris lumbricoides (6,5%) seguido de Hymenolepis nana (4,6%). Entre los métodos de diagnóstico, la TSET tuvo un mayor rendimiento en la detección de enteroparásitos. Conclusiones: La elevada frecuencia de parasitosis intestinal estaría relacionada a inadecuadas condiciones sanitarias presente en algunos distritos de Lima, asociado a factores socioeconómicos y culturales de la población.

Comparative Statistical Analysis

In this article the results of comparative statistical analysis of longtime (from 2005 to 2019) domestic dogs and cats intestinal cestodoses infestation dynamics are represented. The role of infections commons to human and animals to the distribution amount population is determinate. Fecal samples conserved in Turdyev solution were analyzed by combine and sedimentation methods. The prevalence in domestic dogs’ is 26,54% as a one in domestic cats is 18,56%. The level of infection with Cestoda is established in 1,18% of dogs and 1,90% of cats, including Dibothriocephalus sp. Linnaeus, 1758, Spirometra erinacei-eurоpaei Rudolphi, 1819, Taeniidae like eggs, Hydatigera taeniaeformis Batsch, 1786; Lamarck, 1816, Dipylidium caninum Linnaeus, 1758; Railliet, 1892, Mesocestoides lineatus Goeze, 1782; Railliet, 1893 and Hymenolepis nana Siebold,1852. In general, domestic carnivorous from owners, apparently, don’t play significant role in the wide spread of zoonotic Cestoda infections in the Perm population. However, a special attention of medical specialists should be paid to mesocestoidiasis, sparganosis and Hydatigera / strobilocercus infection in connection with their potential danger to human’s health.

The intestinal parasitic diseases directly affect the quality of life of indigenous populations, because of vulnerabilities they experience. This study aimed to understand the prevalence of intestinal parasites among the Haliti-Paresí and relate with sanitation and ethno-development. It is a quantitative and cross-sectional study on indigenous Utiaritiland where reside the Haliti-Paresí, in the middle region northern Mato Grosso, Brazil. Data collection occurred in 2015, from interview with application of semi-structured form and collection of feces for coprological survey.Forty-three indigenous people participated in the study, of an average age of 30.9 years old, mostly women, and a predominance of basic education. The prevalence of enteroparasitosis was 46.6%, predominantly among men, reaching all adolescents, followed by children, without the influence of schooling in the rate of infection. Nine species were detected, being six pathogenic, Giardia duodenalis, Entamoebahistolytica, Ancilostomídeo, Blastocystishominis, Hymenolepis nana and Rodentolepis nana, in addition to three non-pathogenic, Iodamoebabutschlii, Entamoeba coli and Endolimax nana.The sanitation conditions, associated with cultural habits, point to the need for improvement in sanitation, since we detected a high prevalence of intestinal parasitoses in this study. The ethno-development may be crucial as strategies for the maintenance of culture in balance with health and sanitary development.
