          Abstract

          ABSTRACT This is the first report of parasitism by Gongylonema sp. in a free-ranging callitrichid from the Atlantic forest of Espírito Santo, Brazil. A juvenile male of Geoffroy's marmoset (Callithrix geoffroyi) was euthanized due to poor prognosis, then necropsied. Samples of the tongue were collected for routine histological processing. Microscopically, there were transversal sections of adult nematodes within the epithelial layer of the mucosa of the tongue. Lingual scraping demonstrated a small number of oval embryonated eggs with a thick capsule. The morphology of the adult parasites and the eggs, associated with its location, were compatible with the Spirurida nematode of the genus Gongylonema. Further studies are needed to evaluate the impact of this parasite on free-ranging callitrichid populations.

          RESUMO Este é o primeiro relato de parasitismo por Gongylonema sp. em um calitriquídeo de vida livre proveniente da Mata Atlântica do Espírito Santo, Brasil. Um sagui-da-cara-branca (Callithrix geoffroyi), macho, jovem, foi eutanasiado, devido a prognóstico desfavorável, e necropsiado. Fragmentos de língua foram coletados para processamento histológico de rotina. Microscopicamente, havia cortes transversais de nematoides adultos na mucosa da língua. Na raspagem da mucosa da língua, foi observada pequena quantidade de ovos larvados ovais com cápsula espessa. A morfologia do parasita adulto e dos ovos, associada à localização do agente, é compatível com nematoide Spirurida do gênero Gongylonema. São necessários estudos adicionais para avaliar o impacto desse parasito nas populações de calitriquídeos de vida livre.

          Human Gongylonema infection in Iran.

          The first human infection with Gongylonema in Iran is reported in a 35-year-old Iranian woman with complaints of one year duration and treated as a psychotic patient. Two worms, a male, and a female, were retrieved, described, and identified as G. pulchrum based on their morphological characteristics.

            Feeding behavior of Geoffroy's marmoset (Callithrix geoffroyi) in an Atlantic forest fragment of South-eastern Brazil.

            We report on the diet and feeding behaviour of a group of Geoffroy's marmosets (Callithrix geoffroyi) in an Atlantic forest fragment in south-eastern Brazil, studied during the period February 1993 to Januaray 1994. Major food categories were gums (68.6%) fruits (15%), and small animal prey (invertebrates 14.6% and vertebrates 0.8%). Dietary changes were observed between the wet and dry seasons, although they were not statistically significant. Insects and gums were consumed throughout the year but fruits were more prevalent in the diet in the wet season. Plant species exploited for their gums includedInga stipularis, followed byAcacia paniculata, Paulinia carpopodia, andBauhinia angulosa. Chemical analysis of the gum of the four species most used all presented high values for carbohydrates and crude proteins. Fruits of an unidentified species of Myrtaceae (sp. 2) were consumed the most. Animal prey consisted mainly of insects, arachnids, snails, and in three cases, lizards and frogs, with orthopterans being the most prevalent insect prey. This study demonstrates thatC. geoffroyi efficiently exploits resources typically available in secondary and disturbed forest habitat. The main threat to the species is forest destruction, degradation, and fragmentation, but the management of small forest fragments may be an effective corservation strategy.

              Gongylonema pulchrum infection and esophageal squamous cell carcinoma in a vari (Lemur macaco variegata; Kehr 1792).

              This report describes the morphologic and histologic features of a case of esophageal Gongylonema pulchrum infection and esophageal squamous cell carcinoma in a 17-yr-old, female vari (Lemur macaco variegates). The lemur had lived in a German zoo and had a clinical history of dyspnea, vomiting, and anorexia. At necropsy, a whitish, soft, nodular, centrally necrotic mass was found in the caudal third of the esophagus. In addition, numerous intraepithelial nematodes (G. pulchrum) were observed in the entire esophagus. Results suggest a relation between infection with G. pulchrum and development of an esophageal squamous cell carcinoma.
