a case of yellow fever in a brown howler (alouatta fusca) in southern brazil.many brown howlers (alouatta fusca) have died in a 3-month period in a subtropical forest in southern brazil. one was examined after a systemic illness. according to clinical signs, and necropsy and histopathology findings, yellow fever virus (yfv) infection was suspected. tissue sections from liver, kidney, and lymphoid organs were screened by immunohistochemistry for yfv antigens. cells within those tissues stained positively with a polyclonal antibody against yfv antigens (1:1,600 dilution), ...200314667022
impact of yellow fever outbreaks on two howler monkey species (alouatta guariba clamitans and a. caraya) in misiones, argentina.two yellow fever outbreaks (yfos) occurred in northeastern argentina between november 2007 and october 2008, seriously affecting populations of two howler monkey species: the brown howler alouatta guariba clamitans and the black howler alouatta caraya. both howlers live syntopically in el piñalito provincial park, misiones, where four groups (36 individuals) were studied since january 2005. the first dead howlers were found on january 20, 2008, in el piñalito. systematic searches found 14 dead h ...201020095025
Yellow fever outbreak affecting Alouatta populations in southern Brazil (Rio Grande do Sul State), 2008-2009.The natural transmission cycle of Yellow Fever (YF) involves tree hole breeding mosquitoes and a wide array of nonhuman primates (NHP), including monkeys and apes. Some Neotropical monkeys (howler monkeys, genus Alouatta) develop fatal YF virus (YFV) infections similar to those reported in humans, even with minimum exposure to the infection. Epizootics in wild primates may be indicating YFV circulation, and the surveillance of such outbreaks in wildlife is an important tool to help prevent human ...201222020690
global mammal parasite database version 2.0.illuminating the ecological and evolutionary dynamics of parasites is one of the most pressing issues facing modern science, and is critical for basic science, the global economy, and human health. extremely important to this effort are data on the disease-causing organisms of wild animal hosts (including viruses, bacteria, protozoa, helminths, arthropods, and fungi). here we present an updated version of the global mammal parasite database, a database of the parasites of wild ungulates (artioda ...201728273333
