Chronic weight loss in marmosets is often associated with wasting marmoset syndrome (WMS), an important disease that occurs in callitrichid colonies around the world. Even though its etiology is very difficult to determine, particular variables, such as weight loss, diarrhea and alopecia, associated or not with infestation in the pancreatic ducts with Trichospirura leptossoma (Nematoda: Thelazioidea), seem to be linked with the syndrome. This study investigated the histopathology of the lungs, duodenum, liver, gallbladder, extrahepatic bile ducts and pancreatic ducts of six common marmosets (Callithrix jacchus) suffering from severe non-diarrheic weight loss. Three individuals died naturally and the other three were euthanized. Microscopic findings showed the presence of adult flukes (Platynosomum) in the liver. These flukes, which provoke common infection in cats, were also observed inside the gallbladder as well as in the intra and extrahepatic bile ducts in common marmosets. Portal fibrosis was observed in two animals, which developed chronic fibrosing hepatopathy (biliary pattern, grade 3). The disease progresses without diarrhea and without pancreatic lesions or infestation. With the rogression, the animals presented with ascending cholangitis, cholestasis and portal fibrosis, sometimes culminating in secondary biliary cirrhosis. Therefore, this nfirmity, associated with chronic weight loss in common marmosets, could be another tiological factor linked with WMS

La primera tarea de un Instituto nuevo que se dedica a la investigación científica pura dentro de un territorio poco conocido es elaborar un catálogo de las riquezas naturales que constituyen la fauna y la flora de dicho país. Por esta razón es la tarea básica de nuestro Instituto Tropical de Investigaciones Científicas de El Salvador investigar la fauna y flora un mapa geológico del país. Las clases de los vertebrados están terminadas o actualmente en trabajo, tenemos ya en nuestras manos los manuscritos acerca de las aves, anfibios y reptiles de El Salvador; actualmente se están estudiando los mamíferos un especialista en peces, la última clase de vertebrados, llegara a principios del año entrante. También diferentes grupos de los invertebrados, como por ejemplo los caracoles terrestres y varios grupos de insectos están ya investigados. En cuanto a la flora, se está elaborando una descripción de las especies de las catorce familias de la fanerógamas pentacíclicas, a las cuales pertenecen las orquídeas y las bromeliáceas. El trabajo de la fauna y flora tiene dos fines: describir las especies nuevas recién descubiertas y comprobar la presencia de las especies ya conocidas que hasta ahora no se habían descrito.
