human antibody response to a 56-kda purified excretory/secretory product of dirofilaria immitis.	canine dirofilariasis is widespread in urban areas of central and northern colombia. previously we detected specific antibodies against complex antigens from dirofilaria immitis adult worms in individuals from an isolated tikuna indian community in the colombian amazon. in this study a 56 kda polypeptide from the adult d. immitis excretory/secretory (e/s) products is identified by western blot, isolated by elution from polyacrilamide gels and applied in an elisa-based test for the detection of s ...	2000	11169274
prevalence of toxoplasma gondii in dogs from colombia, south america and genetic characterization of t. gondii isolates.	the prevalence of toxoplasma gondii in 309 unwanted dogs from bogotá, colombia, south america was determined. antibodies to t. gondii were assayed by the modified agglutination test (mat) and found in 52 (16.8%) of 309 dogs with titers of 1:20 in 20, 1:40 in six, 1:80 in 17, 1:160 in three, 1:320 in three, 1:1280 or higher in three. some organs obtained after necropsy of dogs (hearts, tongues and brains, either separately or pooled) were used in bioassays carried out in mice (37 samples, of whic ...	2007	17257761
