Título:Dirofilariosis canina en los distritos colindantes con la ribera del río Lurín^ies / Canine heartworm in the districts bordering the river Lurin

Resumen:Heartworm is a parasitic disease caused by Dirofilaria immitis. The adult form of the parasite can be found in the right heart and pulmonary arteries, especially in canines. The objective of the study was to quantify the presence of D. immitis in districts located along the Lurín river (Cieneguilla, Pachacamac and Lurín). Blood samples were collected from 177 dogs (males and females) from January till July 2000. The age of the animals varied from 1 to 10 years. Three methods were conducted for diagnosing Dirofilaria: the microhaematocrit and the modified Knott techniques were used for the identification of microfilarias, and ELISA for the determination of secretion / excretion antigens of mature forms. Cieneguilla was the district with the highest frequency of heartworms. 6.4 percet of positive samples were obtained by the microhaematocrit and modified Knott techniques whereas 12.8 percent were obtained by ELISA. In Lurín was observed 2.5 percent using the microhaematocrit and modified Knott techniques whereas 7.5 percet by ELISA. In Pachacamac was only observed 2 percent of positive samples by the ELISA technique. In conclusion, the estimated prevalence in the studied area was 7.3 percet ± 3.8 CI when ELISA was used and 2.8 percent ± 2.4 CI when microhaematocrit or the modified Knott techniques were used. The relative low prevalence of the disease in the area does not constitute a serious parasitic problem, however, proper monitoring should be considered. (AU)^ien.

Título:Estudio de la dirofilariosis canina en la ribera del río Chillón, Lima^ies / Study of canine heartworm in the banks of the Chillon River, Ontario
Fuente:Rev. invest. vet. Perú;13(1):72-76, ene-jun. 2002. ^bilus.
Resumen:Se determinó la presencia de dirofiliarosis (D. immitis) en distritos de Lima ribereños al Río Chillón (Puente Piedra, Comas, Carabayllo, Los Olivos y Ventanilla). Se tomaron muestras de sangre en vacuotainers con anticoagulante de 200 perros al azar, sin distinción de raza ni sexo y con edades comprendidas entre 1-10 años. El diagnóstico se realizó mediante las pruebas del método del microcapilar, el Knott modificado para microfilarias, y la prueba de ELISA que detecta antígenos de secreción y excreción del parásito adulto. Los resultados mostraron una prevalencia en la zona estudiada de 3 + 2.4% mediante la prueba enzimática ELISA, mientras que por las pruebas de microcapilar y Knott modificado se encontró un total de 1.5 + 1.7 por ciento. La prevalencia de dirofilariosis en los distritos fue: Puente Piedra con 4.4 por ciento de animales positivos en las tres pruebas; Ventanilla con 5 por ciento donde sólo se detectó presencia de Dirofilaria immitis mediante la prueba de ELISA; Comas con 2.5 por ciento de animales positivos mediante las tres pruebas diagnósticas; Los Olivos 2.5 por ciento de perros positivos mediante la prueba de ELISA; y Carabayllo con 0 por ciento. Se concluye que la dirofilariosis canina en la zona de estudio no constituye un grave problema parasitario; sin embargo no debe descuidarse las medidas de prevención y control a fin de evitar su aumento y propagación. (AU)^iesThe main objective of the study was to determine the presence of dirofilariosis (D. immitis) in districts of Lima located along the Chillon river (Puente Piedra, Comas, Carabayllo, Los Olivos and Ventanilla). Blood samples were collected in vacuotainer tubes containing anticoagulant from 200 dogs of 1-10 years of age that were selected at random, without distinction among breeds and sex. Samples were processed using three diagnostic tests: the method of microcapillary, Knott modified for microfilarias, and the ELISA test that detects antigens of secretion and excretion of the adult parasite. The overall results indicated 3.2 ± 2.4 percent of infection when using the enzymatic ELISA test, whereas 1.5 ± 1.7 percent when using the Knott modified and the mircocapillary tests. The prevalence of dirofilariosis in the monitored districts was: 4.4 percet in all three tests in Puente Piedra, 5 percent using the ELISA test in Ventanilla; 2.5 percent in all three tests in Comas, 2.5 percent using the ELISA test en Los Olivos; and 0 percent in Carabayllo. It was concluded that dog dirofilariosis does not represent a mayor parasitic problem; however preventive and control measures should not be left aside in order to keep the current level under control.
