En el presente trabajo, fueron analizados los hallazgos de helmintos obtenidos durante un año de exámenes coprológicos, en un centro de fauna cautiva en Colombia. Se realizaron 375 exámenes coprológicos, con muestras recolectadas a partir de diferentes especies de anfibios, reptiles, aves y mamíferos. Los porcentajes de animales parasitados con helmintos, fueron: anfibios el 24%, reptiles el 17%, aves 16% y mamíferos el 43%. Las tasas más altas de parasitismo por helmintos fueron producidas por los geohelmintos, encontrando con mayor frecuencia los grupos estrongilideos (53%) y ancylostomideos (33%) principalmente en anfibios, reptiles y mamíferos. Para el 100% de las aves positivas se reportó Capillaria sp.; también se encontró en mamíferos en un 7 %. Los helmintos de menor reporte fueron un acantocéfalo, un cestodo y tres nematodos no identificados.

The present study analyzed the findings of helminths obtained during one year of coprological tests, in a captive fauna center in Colombia. Three hundred, seventy-five (375) coprological tests were made with samples collected from different species of amphibious, reptiles, birds, and mammals. The percentages of animals presenting helminths were as follows: amphibious 24%, reptiles 17%, birds 16%, and mammals 43%. The highest rates of parasitism for helmints were produced by geo-helminths, with a highest frequency for the strongylid groups (53%) and anchylostomides (33%) mainly in amphibious, reptiles and mammals. For 100% of positive birds Capillaria sp was reported and it was also found in mammals (7%). Helminths of lesser report were one acantocephalo, one cestode and three unidentified nematodes.

Bursera graveolens (Burseraceae), known in Colombia as "sasafrás", is useful for its medicinal properties and is rich in secondary metabolites. In our research, we carried out antimicrobial tests of several fractions and ethanolic extracts from aerial parts against Bacillus subtilis and Staphylococcus aureus, that showed growth inhibitory activity when applied at 250 mg/mL for extracts and 150 mg/mL for fractions. We carried out an antiinflamatory assay also, that showed 71% of inhibition by extracts (81% of Indomethacin) and 70% of inhibition by fractions (78% of Indomethacin). Phytochemical investigation of the bark of Bursera graveolens (Burseraceae) yielded three tetracyclic triterpene acids that have oxygenation in C-3, carboxylic acid in C-21 and unsaturation in C-24 and have been identified as 3-oxotirucalla-8,24-dien-21-oic acid (b-elemonic acid), 3a-hydroxytirucalla-8,24-dien-21-oic acid (a-elemolic acid) and 3a-hydroxytirucalla-7,24-dien-21-oic acid. The isolated compounds were identified using spectroscopic methods including one and two-dimensional Nuclear Magnetic Resonance (COSY, HMQC, HMBC, NOESY) experiments and comparison with published data. This is the first report of the isolated compounds in Bursera graveolens and they have a very important chemotaxonomic significance within the Burseraceae family and related families from the order Rutales.
