(2004-06-01)Alouattamyia baeri es una especie de cuterébrido cuya larva se asocia con el parasitismo en primates del Nuevo Mundo (Catts, 1982). La descripción de la morfología fue realizada por Shannon y Greene (1926) con ejemplares ... -
Infectious agents in acute and chronic diarrhea of chilhood
(Chronic diarrea a in children: Raven Press p. 237 - 252, 1984)Even today acute diarrheal disease is thought of by many laymen as well as by some medical professionals in developing countries as being a syndrome of alimentary origin. Despite recognition of shigellosis, cholera, ... -
Infestación múltiple por ácaros ectoparásitos en conejos de crianza
(2011-06-01)Six breeding rabbits (New Zealand strain) were observed with crusted and pruritic dermal lesions. These lesions were located predominantly in ears, nose, nails and feet. Dermal material collected by scraping showed the ... -

(2002-06-01)Se realizó una encuesta entomológica en 157 viviendas pertenecientes a cuatro zonas de la Meseta Central de Costa Rica, donde la enfermedad de Chagas es endémica. Trece casas (8,3%) presentaron una infestación positiva por ... -
Inflammation induced by Bothrops asper venom: release of proinflammatory cytokines and eicosanoids, and role of adhesion molecules in leukocyte infiltration
(2005-12)Bothrops asper venom (BaV) causes systemic and local effects characterized by an acute inflammatory reaction with accumulation of leukocytes and release of endogenous mediators. In this study, the effects of BaV on the ... -
Inflammatory effects of BaP1 a metalloproteinase isolated from Bothrops asper snake venom: leukocyte recruitment and release of cytokines
(2006-04)The inflammatory events induced by BaP1, a 22.7 kDa metalloproteinase isolated from Bothrops asper snake venom, were studied. BaP1 i.p. injection in mice induced a marked inflammatory cell infiltrate into peritoneal cavity ... -
