Neospora caninum is a parasite of dogs that causes high rates of abortion and neonatal mortality in cattle throughout the world. The objective of the study was to determine the prevalence of Neospora caninum in dogs from districts of Molinopampa and Leymebamba, province of Chachapoyas, Amazonas. A total of 142 serum samples were evaluated (63 from Molinopampa and 79 from Leymebamba) for the detection of antibodies using the indirect immunofluorescence test (IFAT). The 28.9 ± 7.5% of the animals were positive to N. caninum. A seroprevalence of 34.9 ± 11.8% and 24.1 ± 9.4% were found in dogs of Molinopampa and Leymebamba districts, respectively. This results demonstrate the existence of a high seroprevalence of dogs infected with Neospora caninum in the region.
El objetivo del presente estudio fue determinar la seroprevalencia de Neospora caninum en bovinos lecheros del valle de Lima en el año 2000. Se evaluaron 304 sueros de vacas lecheras adultas provenientes de 19 establos lecheros ubicados en la zona norte (n = 12) y en la zona sur (n = 7) del valle de Lima, para detectar anticuerpos contra N. caninum mediante la prueba de inmunofluorescencia indirecta.

The object of this study was to assess the prevalence of Giardia sp. in domestic canines from the Southern part of Lima, Peru. A total of 204 fecal samples from canines of the districts of Surco, Barranco, Chorrillos, San Juan de Miraflores, Villa María del Triunfo and Villa El Salvador were recolected. The animals were stratified according to the socioeconomic level of the owner. Samples were analized by the direct examination test and by the spontaneous sedimentation test for detection of Giardia sp. The direct examination test showed 8.8 ± 3.9% (18/204) of positive samples whereas the spontaneous sedimentation test gave a prevalence of 15.7 ± 5.0 (32/204). The latter test showed to be more sensitive than the direct examination test when results were compared by the McNemar test. The Logistic Regression test failed to show a significative relationship between presence of Giardia sp. and socioeconomic level of the owner or sex of animal. Puppies (<1 year old) were more affected than adults (>1 year). Likewise, parasitic forms were more frequently detected in soft than in normal feces. The results indicated the existence of a moderate prevalence of Giardia sp. infection in canine population of the Southern part of Lima City, suggesting that canine giardiasis in Lima would be a serious problem of Public Health.Key words: Giardia sp., canine, Lima, spontaneous sedimentation RESUMENEl objetivo del presente estudio fue determinar la prevalencia de Giardia sp. en caninos domésticos en el cono sur de la ciudad de Lima. Se recolectaron 204 muestras de heces de caninos domésticos procedentes de hogares en los distritos de Surco, Barranco, Chorrillos, San Juan de Miraflores, Villa María del Triunfo y Villa El Salvador. Los hogares se estratificaron de acuerdo al nivel socioeconómico de los propietarios. Las muestras se analizaron mediante las técnicas de examen directo y sedimentación espontánea para la detección de Giardia sp. La prueba de examen directo dio el 8.8 ± 3.9% (18/204) de muestras positivas mientras que la prueba de sedimentación espontá-nea dio una prevalencia de 15.7 ± 5.0% (32/204). La técnica de sedimentación espontánea demostró ser más sensible que el examen directo hallándose diferencias estadísticas significativas mediante la prueba de McNemar. La prueba de Regresión Logística no mostró relaciones significativas entre la presencia de Giardia sp. con el nivel socioeconómico de procedencia o el sexo de los canes. Los cachorros (<1 año) fueron más susceptibles que los adultos (≥1 año). Así mismo, las formas parasitarias del orga-
The objective of this paper was to determine the contamination with Toxocara sp. in public parks ofMetropolitan Lima and Callao. Turf samples were collected from 558 out ofthe 1,964 parks existing in Lima and Callao (108, 98, 151and123 from the northern, southern, eastern and western part ofLima and 78 from Callao) during December 1998 and August 199 using the double "W" method. Samples were processed by the flotation method using ClNa saturated solution. A sample was considered positive when presented at least one egg of Toxocara sp. The eggs were incubated and orally inoculated to mice and quails to verify the viability of eggs. Parks were grouped according to the level of conservation as good (well covered with grass), moderate (around 50% covered with grass) and poor conserved (without grass); and according to the social economic level as high, middle-high, middle, middle-low and low. The prevalence rate was 34 ± 9% (mean ± confidence interval), 30±9,41±8, 63 ± 9 and 37±11 % forparks innorthern, southern, • eastern and western part ofLima and Callao, respectively. Contamination level was 73, 49 and 16% in parks with good, moderate and poor level of conservation, whereas according to the social economic level was 73, 62, 47, 29 and 30% in parks with high, middle-high, middle, middle-low and low social economic levels, respectively. Abundant green material and high humidity in good conserved parks would favour conservation of Toxocara sp. eggs. On the other hand, the absence of Toxocara sp. eggs in poorly conserved parks would be dueto direct solar radiation on the eggs. Finally, inoculated mice and quails developed migrant larva, which is indicative of the infective capacity of the eggs.
RESUMENSe determinó la prevalencia de Paramfistómidos en bovinos del distrito de Yurimaguas, provincia de Alto Amazonas, Loreto. Se colectaron muestras de heces en 421 bovinos, entre junio de 2006 a febrero de 2007, para su evaluación coproparasitológica con la técnica de sedimentación espontánea. Se obtuvo una prevalencia del 44.2 ± 4.7%. En la prueba de regresión logística se determinó que la edad (p<0.05), y no el sexo, constituía factor de riesgo, donde bovinos mayores de tres años de edad presentaron 3 ó más veces mayor riesgo de presentar esta parasitosis que animales menores. El alto grado de prevalencia de Paramfistomosis estaría influenciado por las condiciones medioambientales favorables presentes en la zona de estudio, así como por la falta de estrategias de prevención y control en la población bovina local.Palabras clave : Paramfistómidos, paramfistomosis, prevalencia, bovinos, sedimentación, Yurimaguas, Loreto ABSTRACTThe prevalence of Paramphistomids in cattle of Yurimaguas district, Alto Amazonas province, Loreto was evaluated. Fecal samples from 421 cattle were collected since June 2006 till February 2007 for the coproparasitological evaluation using the spontaneous sedimentation technique. The resulting prevalence was 44.2 ± 4.7%. The logistic regression test indicated that age (p<0.05), and not sex was a risk factor where animals over three years of age had three times more risk to suffer the disease than younger animals. The
