| [frequency of finding helminths eggs in canine stool samples collected in public places in the la plata city, argentina]. | a study was carried out in order to determine the level of contamination with helminth eggs in different sectors of the city of la plata, argentina. a total of 351 fecal pools were collected from streets (328) and parks and public places (23) of this locality. of these fecal pools, 117 (33.3%) contained eggs of at least one helminth species. the overall frequencies found were: uncinaria sp. 16.0%, trichuris vulpis 9.7% and toxocara canis 10.5%. | 1993 | 7993539 |
| human toxocarosis. its seroprevalence in the city of la plata. | toxocara canis is very common in dogs throughout the world. it is the primary cause of visceral larva migrans (vlm) in humans. soil contaminated with t. canis embryonated eggs is the main source of infection of man. our objective was to describe toxocara seroprevalence in humans in the city of la plata associated with some determinants such asage, presence or absence of clinical manifestations and risk factors. blood samples were collected at random from 156 patients of different sex and age, wi ... | 2000 | 10800184 |
| biological interaction between soil fungi and toxocara canis eggs. | fungi from the soil of public areas in la plata, argentina were isolated and evaluated for their biological interaction with toxocara canis eggs in vitro. we isolated and identified two fungal species: fusarium pallidoroseum and mucor hiemalis. each species was co-cultured with t. canis eggs in sterile distilled water. the samples were observed by light and scanning electron microscopy (sem) at days 4, 7 and 14 post-inoculation. under the conditions of our experiments, f. pallidoroseum exhibited ... | 2002 | 11750118 |
| epidemiology of toxocara canis in the dog population from two areas of different socioeconomic status, greater buenos aires, argentina. | toxocara canis infection in dogs is a public health problem in most countries, although it has been poorly documented in many of them. the main objective of the present work was to investigate the epidemiology of infection in the canine populations from two areas of buenos aires of different socioeconomic status and urban conditions: a middle-income neighbourhood (min) and a low-income neighbourhood (lin). this study evaluated the prevalence of infection in dogs by parasitological and serologica ... | 2003 | 12935743 |
| an epidemiological study of gastrointestinal parasites of dogs from southern greater buenos aires (argentina): age, gender, breed, mixed infections, and seasonal and spatial patterns. | a total of 2193 fecal samples from owned dogs were collected during the 2003-2004 period in southern greater buenos aires, and were evaluated for the presence of intestinal parasites by a flotation-centrifugation method. the overall prevalence was 52.4%, and the 11 species found were: ancylostoma caninum (13%), isospora ohioensis complex (12%), toxocara canis (11%), trichuris vulpis (10%), sarcocystis sp. (10%), giardia duodenalis (9%), isospora canis (3%), hammondia-neospora complex (3%), dipil ... | 2006 | 16364551 |
| [nematophagous fungi of toxocara canis eggs in a public park of la plata, argentina]. | fungi have showed a great potential for the biological control of nematodes. however, they have not been evaluated for the control of animal and/or human parasites transmitted by egg contaminated soils. environmental contamination with toxocara spp. eggs is a public health problem. accidental swallowing of toxocara canis eggs (a nematode of dogs) usually results on a zoonotic infection (toxocarosis). the objectives of this research were: 1) to test the presence of antagonistic fungi against t. c ... | 2007 | 17592887 |
| [dog fouling and helminth contamination in parks and sidewalks of buenos aires city, 1991-2006]. | the aim of this study was to provide data on canine fecal and helminthic contamination from parks and sidewalks in buenos aires city, collected by the laboratory of general parasitology, school of sciences, university of buenos aires. a census of dog feces was performed in 1-11 parks per year between 1991 and 2006, a single day each year. in the period 2000-2006, the census included feces on sidewalks surrounding the park. thirty fresh fecal samples were randomly collected from each park to dete ... | 2010 | 20679057 |
