serologic evidence of west nile virus infection in free-ranging mammals, slidell, louisiana, 2002.after an outbreak of west nile virus (wnv) infections in slidell, louisiana, in 2002, we detected neutralizing antibodies to wnv in 13 of 120 mammals, representing five of six species sampled. seroprevalence was measured in opossum, didelphis virginiana (75%, n = 8), raccoons, procyon lotor (60%, n = 5), black rats, rattus rattus (6%, n = 36), hispid cotton rats, sigmodon hispidus (4%, n = 24), and eastern gray squirrels, sciurus carolinensis (2%, n = 43).200516187899
epithelial cell lines of the cotton rat (sigmodon hispidus) are highly susceptible in vitro models to zoonotic bunya-, rhabdo-, and flaviviruses.small mammals such as bats and rodents have been increasingly recognized as reservoirs of novel potentially zoonotic pathogens. however, few in vitro model systems to date allow assessment of zoonotic viruses in a relevant host context. the cotton rat (sigmodon hispidus) is a new world rodent species that has a long-standing history as an experimental animal model due to its unique susceptibility to human viruses. furthermore, wild cotton rats are associated with a large variety of known or pote ...201627142375
potential sympatric vectors and mammalian hosts of venezuelan equine encephalitis virus in southern mexico.arboviruses are important zoonotic agents with complex transmission cycles and are not well understood because they may involve many vectors and hosts. we studied sympatric wild mammals and hematophagous mosquitoes having the potential to act as hosts and vectors in two areas of southern mexico. mosquitoes, bats, and rodents were captured in calakmul (campeche) and montes azules (chiapas), between november 2010 and august 2011. spleen samples from 146 bats and 14 rodents were tested for molecula ...201728384059
