ABSTRACT
Se presenta tres casos de filariosis de pacientes varones procedentes de la selva peruana (Junín, San Martín y Pucallpa). Un caso presentó filarias en el globo ocular y frotís sanguíneo, que según morfología, serología y biología molecular se determinó como un posiblecaso de filariosis zoonótica por Onchocerca spp. Los otros dos casos fueron causados por Dirofilaria spp. uno presentó un nódulo en el pómulo y sensación de movilidad en la zona y fue diagnosticado por serología y el último caso se le extrajo una filaria del dedo pulgar de la mano y fue identificado como tal por morfología y biología molecular. Estos casos son los primeros reportes en el Perú por Dirofilariaspp. y Onchocerca spp.
We present three cases of male patients with filariasis from the Peruvian jungle (Junin, San Martin and Pucallpa). One case presented filariae in the eyeball and blood smears, which according to morphology, serology and molecular biology was established as a possiblecase of zoonotic filariasis by Onchocerca spp. The other two cases were caused by Dirofilaria spp. introduced a cheekbone in a lump sensation and mobility in the area and was diagnosed by serology and the last case was extracted filaria a thumb of the hand and was identified as such by morphology and molecular biology. These cases are the first reports in Peru by Dirofilaria spp. and Onchocerca spp.

In order to support the case for a certification of elimination of lymphatic filariasis (LF) in some Caribbean countries, we compared the prevalence of circulating Wuchereria bancrofti antigen in communities in Guyana, Suriname, and Trinidad. For the study, we assayed school children in six communities in Guyana, five communities in Suriname, and three communities in Trinidad for the prevalence of circulating W. bancrofti antigen, using a new immunochromatographic test for LF. We also assayed adults in these three countries, with a special focus on Blanchisseuse, Trinidad, where mass treatment for LF elimination had been carried out in 1981. The prevalences of W. bancrofti circulating antigen found in the school children populations ranged from 1.7 to 33.2 in Guyana and were 0.22 overall in Suriname and 0.0 in Trinidad. Among adults in two Guyana communities the prevalences were 16.7 and 32.1. The results were all negative from 211 adults in communities in the north, center, and south of Trinidad, as well as from 29 adults in Suriname. The data suggest that contrary to reports of LF endemicity from the World Health Organization, LF may no longer be present in Trinidad and may be of very low prevalence in Suriname. Trinidad and Tobago and other Caribbean nations proven negative could seek to be awarded a certificate of LF elimination. In Suriname the small localized pocket of infected persons who may serve as a reservoir of LF infection could be tested and appropriately treated to achieve LF elimination. Such LF-positive countries as Guyana should access new international resources being made available for LF elimination efforts. An adequate certification program would help identify which countries should seek the new LF elimination resources
