          Abstract

          RESUMEN Se presenta el caso de un espécimen de Leopardus pardalis, macho y peso de 15.6 kg, hallado con descomposición parcial en una vía del sector rural del municipio de Arauca, Colombia. En la necropsia se encontraron 36 formas parasitarias de nematodos, con una longitud aproximada de 3.4 cm, las cuales fueron identificadas como Toxocara cati por la presencia de aletas laterales en el extremo cervical, presencia de tres labios y de una cutícula anillada. Este es el primer reporte en Colombia de la especie parasitaria en este felino silvestre, indicando que la especie L. pardalis puede ser potencial portador y diseminador de T. cati.

          ABSTRACT It is reported the case of a Leopardus pardalis specimen, male, 15.6 kg body weight, found with partial decomposition in a road in the rural sector of the municipality of Arauca, Colombia. At necropsy, 36 parasitic forms of nematodes were found, with an approximate length of 3.4 cm, which were identified as Toxocara cati by the presence of lateral fins at the cervical end, the presence of three lips and a ringed cuticle. This is the first report in Colombia of the parasitic species in this wild feline, indicating that the species L. pardalis may be a potential carrier and disseminator of T. cati.

          Toxocariasis in humans: clinical expression and treatment dilemma.

          A new scheme of clarifying clinical forms of toxocariasis is proposed to include: (i) systemic forms: classical VLM and incomplete VLM; (ii) compartmentalized forms: ocular and neurological toxocariasis; (iii) covert toxocariasis; and (iv) asymptomatic toxocariasis. The following markers are helpful in defining clinical forms namely, patient characteristics and history, clinical symptoms and signs, positive serology, eosinophilia and increased levels of IgE. Amongst the available drugs albendazole is the most commonly used, although other benzimidazole compounds have a similar efficacy. The recommended dose of albendazole is 15 mg kg(-1) body weight daily for 5 days and in some cases with VLM syndrome the treatment needs to be repeated. An evaluation of treatment efficacy can be made by observing a rise in eosinophilia within a week followed by any improvement in clinical symptoms and signs, lower eosinophilia and serological tests taken over a period of at least 4 weeks. In addition to clinical rationales for the specific treatment of VLM and OLM, preventive treatment needs to be considered bearing in mind the increasing risk of larvae localizing in the brain during the course of an infection. To reduce migration of Toxocara larvae a single course of albendazole is suggested in cases where eosinophilia and serology are at least moderately positive.

            Ocelot Leopardus pardalis in Belize: the impact of trap spacing and distance moved on density estimates

            We used remote cameras to obtain information on an elusive species and to examine the effects of different camera trapping methodologies on abundance estimates. We determined activity pattern, trail use, trap success, and density of ocelot Leopardus pardalis in seven camera-trap surveys across two habitat types in western Belize: tropical broad-leaf rainforest and tropical pine forest. Ocelots in the rainforest were active mostly at night, in particular immediately after sunset, and they travelled on low-use roads (especially in the wet season) and high-use roads (especially in the dry season) more than established and newly cut trails. Trap success was relatively high in the rainforest (2.11–6.20 captures per 100 trap nights) and low in the pine forest (0.13–0.15 captures per 100 trap nights). Camera trapping combined with mark-recapture statistics gave densities of 25.82–25.88 per 100 km 2 in the broad-leaf versus 2.31–3.80 per 100 km 2 in the pine forest. Density estimates increased when animals repeatedly captured at the same camera (zero-distance moved animals) were included in the buffer size analysis. Density estimates were significantly negatively correlated with distance between cameras. We provide information on ocelot population status from an unstudied portion of its range and advise that camera trap methodologies be standardized to permit comparisons across sites.

              Camera trap survey of medium and large mammals in a montane rainforest of northern Peru

              Camera traps are a powerful tool for inventorying elusive and rare species and very useful to obtain ecological data for plans that involve wildlife conservation. In Peru, several surveys have been carried out in lowland Amazonia especially in the southeastern part of the country, but none in montane cloud forests or Yungas. We present the first camera trap studies produced in Peruvian Yungas at the locality of Querocoto village (Chota, Cajamarca), based on 2002 (dry season) and 1264 (wet season) camera traps-days (CTD). Two localities were surveyed in wet and dry season: The Pagaibamba Protection Forest and the San Lorenzo Forest. The wet season study was carried out in October and November, and the dry season in July to September of 2008. Eight mammalian species were recorded in both seasons. Some 66 (91.7%) independent records were obtained in the dry season, but only six (8.3%) in the wet one, suggesting a seasonality effect. The Mountain Paca Cuniculus taczanowskii was the most commonly photographed species, with 17.0 and 1.6 capture frequencies (dry and wet season respectively), whereas the Long-tailed weasel Mustela frenata (0.5 capture frequency in the dry season) was the most rare species. Activity patterns suggest that Mountain Paca C. taczanowskii and the Andean Skunk C. chinga are nocturnal, while Spectacled Bear T. ornatus and Tayra E. barbara are diurnal in the study area. Our records of the Ocelot Leopardus pardalis and the Tayra E. barbara are among the highest altitudinal records known for each species. In addition, the Anta Tapirus pinchaque was also identified by its tracks, representing one of the first record known south of the Huancabamba Depression.
