Arenavirus antibody in rodents indigenous to coastal southern California.

Abstract

Abstract. The purpose of this study was to extend our knowledge on the geographic and natural rodent host ranges of New World arenaviruses in California. Sera from 1,094 sigmodontine and 112 murine rodents were tested for antibody against Whitewater Arroyo and Amapari viruses. Antibody was found in 55 (4

Natural host relationships and genetic diversity of Whitewater Arroyo virus in southern Texas.

“…Blood samples from 200 rodents were tested for antibody against WWA virus using an enzymelinked immunosorbent assay previously described. 7 The test antigen was a lysate of Vero E6 cells infected with the WWA virus prototype strain AV 9310135. The control (comparison) antigen was a lysate of uninfected Vero E6 cells.…”

Epizootiology of Tacaribe Serocomplex Viruses (Arenaviridae) Associated with Neotomine Rodents (Cricetidae, Neotominae) in Southern California

“…f SB-1, Vandenberg Air Force Base; SB-3, Romero Canyon, Santa Ynez Mountains; LA-6, near Dry Canyon, Santa Monica Mountains; LA-9, Solstice Canyon, Santa Monica Mountains; LA-11, Zuma Canyon, Santa Monica Mountains; ORA-3, El Cariso #1, Santa Ana Mountains; ORA-4, El Cariso #2, Santa Ana Mountains; ORA-6, Lucas Canyon, Santa Ana Mountains; ORA-HJC, Holy Jim Canyon, Santa Ana Mountains; ORA-SC, near the city of San Clemente; RIV-1, near the Palo Verde Diversion Dam; RIV-4, San Jacinto Valley; RIV-5, Morrell Potrero, Santa Ana Mountains; RIV-6, Bear Canyon Trailhead, Santa Ana Mountains; RIV-7, Santa Rosa Plateau. Rodents TK90837, TK90798, and TK93458 were positive for antibody to Whitewater Arroyo virus strain AV 9310135 in a previous study (Bennett et al 2000) and positive for N protein gene RNA in previously unpublished work. None of the rodents tested for anti-arenavirus antibody in this study were from ORA-HJC (33°40¢39 †N, 117°31¢03 †W) or ORA-SC (33°24¢35 †N, 117°35¢24 †W).…”

“…The blood and serum samples were tested for immunoglobulin G (IgG) to WWAV strain AV 9310135 (Fulhorst et al 1996), using an enzyme-linked immunosorbent assay (ELISA) (Bennett et al 2000). We note that IgG to BCNV in naturally infected big-eared woodrats and naturally infected California mice is reactive to AV 9310135 in ELISA (Fulhorst et al 2002).…”

“…The nucleotide sequences in FJ907244, KC807183, KC807184, and KC807187-KC807195 were from rodents tested for anti-arenavirus antibody in this study. The 6 other N protein gene sequences were from rodents that were positive for anti-arenavirus antibody in previous studies (Bennett et al 2000, Fulhorst et al 2002.…”

Antibodies to Tacaribe Serocomplex Viruses (FamilyArenaviridae, GenusArenavirus) in Cricetid Rodents from New Mexico, Texas, and Mexico

“…For example, the hispid cotton rat (Sigmodon hispidus) in southern Florida is the principal host of TAMV (Calisher et al 1970, Jennings et al 1970, and the southern plains woodrat (Neotoma micropus) in Dimmitt and La Salle counties in southern Texas is the principal host of CTNV (Fulhorst et al 2002b, Cajimat et al 2007a). Other natural hosts of Tacaribe serocomplex viruses in North America include the white-throated woodrat (N. albigula) in Arizona, Colorado, New Mexico, and Oklahoma, bushy-tailed woodrat (N. cinerea) in Utah, Mexican woodrat (N. mexicana) in Arizona, Colorado, New Mexico, and Utah, southern plains woodrat in Colorado, Stephen's woodrat (N. stephensi) in Arizona and New Mexico, Bryant's woodrat (N. bryanti, formerly N. lepida; Patton et al 2008), dusky-footed woodrat (N. fuscipes), large-eared woodrat (N. macrotis), brush mouse (Peromyscus boylii), California mouse (P. californicus), cactus deermouse (P. eremicus), North American deermouse (P. maniculatus), and western harvest mouse (Reithrodontomys megalotis) in California, and marsh oryzomys (Oryzomys palustris) in Florida , 2001a, 2002a, Kosoy et al 1996, Bennett et al 2000, Calisher et al 2001, Abbott et al 2004, Cajimat et al 2007b. The aim of this study was to extend our knowledge of the natural host range and geographical distribution of Tacaribe serocomplex viruses associated with cricetid rodents in North America.…”
