| [epidemiology of toxoplasmosis in costa rica: the importance of domestic rodents]. | a positive dye test for toxoplasma antibodies was observed in 5% of 100 mice (mus musculus) and 30.4% of 23 rats (rattus norvegicus and r. rattus). the parasite was isolated from two mice. the animals were captured in several urban localities in the metropolitan area of san josé, costa rica. the number of positive animals found appears to be enough to infect cats, whose principal source of infections are the toxoplasma cysts in the rodents. therefore it is apparent that domestic mice and rats, b ... | 1978 | 751107 |
| human toxoplasmosis and cat contact in costa rica. | we studied the prevalence of antibody to toxoplasma gondii in 883 costa ricans between the ages of 15 and 26 years (mean 20.3). there were seven populations, two rural and five urban. the overall antibody prevalence was 61.4%. because antibody prevalence was 57.1% in the 14 people who ate raw meat, and 61.6% in the 294 people who consumed raw eggs, meat and eggs could be excluded as important modes of transmission. we ascertained the presence of cats, type of soil contact, and flooring in the ki ... | 1980 | 7446808 |
| [fur color gene profiles and length of hair of several cat populations in cuba, costa rica, colombia, paraguay, chile and argentina, and possible genetic origins of these cat populations]. | until the present moment, only a scarce number of latin american domestic cat populations have been studied from a population genetic standpoint. for this reason, the cat populations of la havana (cuba), san josé (costa rica), bogota and ibagué (colombia), asuncion (paraguay), santiago (chile) and buenos aires (argentina) were sampled for several coat genes. the results obtained were as follows: (1) there was a strong genetic resemblance between several hispanic american cat populations (especia ... | 2002 | 11902150 |
| a survey on triatoma dimidiata in an urban area of the province of heredia, costa rica. | triatoma dimidiata has been found in several cities and towns of those countries where the insect is a domestic or peridomestic pest. in central america, urban infestations occur in the capitals of at least five countries. during 2001 and 2002 a survey was carried out in the county of san rafael, heredia province, located 15 km northwest of san josé, capital of costa rica, in order to determine the degree of infestation by t. dimidiata in an entire city block. six peridomestic colonies of the in ... | 2005 | 16302059 |
