| serologic survey for selected microbial agents in mammals from alberta, 1976. | blood samples were taken from humans and several species of free-ranging wild mammals from five different geographic areas of alberta, canada. sera were tested for antibody to eastern equine encephalitis (eee) virus, western equine encephalitis (wee) virus, st. louis encephalitis (sle) virus, powassan (pow) virus, the snowshoe hare (ssh) strain of the california group (cal) of viruses, northway (nor) virus, klamath (kla) virus, infectious bovine rhinotracheitis (ibr) virus, and two bacteria, bru ... | 1981 | 6273600 |
| seroprevalence of selected disease agents from free-ranging black bears in florida. | sera obtained from 66 free-ranging florida black bears (ursus americanus floridanus) from three geographic areas of florida (usa) between november 1993 and august 1995 were tested for antibodies to 13 disease agents. antibody prevalences were 3 positive of 37 tested (8%) coxiella burnetti, 37 of 66 (56%) toxoplasma gondii, 3 of 61 (5%) bluetongue virus/epizootic hemorrhagic disease virus (btv/ehdv), 4 of 66 (6%) canine adenovirus-type 1, 5 of 66 (8%) canine distemper virus (cdv), 10 of 62 (16%) ... | 1998 | 9706572 |
| ticks and tick-borne pathogens and putative symbionts of black bears (ursus americanus floridanus) from georgia and florida. | ticks were collected from 38 black bears (ursus americanus floridanus) from northwestern florida (n = 18) from 2003 to 2005 and southern georgia (n = 20) in 2006. five species (amblyomma americanum, a. maculatum, dermacentor variabilis, ixodes scapularis, and i. affinis) were collected from florida bears, and 4 species (a. americanum, a. maculatum, d. variabilis, i. scapularis) were collected from bears in georgia. ixodes scapularis was the most frequently collected tick, followed by d. variabil ... | 2009 | 19413369 |
| demographic characteristics and infectious diseases of a population of american black bears in humboldt county, california. | american black bears (ursus americanus) are common, widely distributed, and broad-ranging omnivorous mammals in northern california forests. bears may be susceptible to pathogens infecting both domestic animals and humans. monitoring bear populations, particularly in changing ecosystems, is important to understanding ecological features that could affect bear population health and influence the likelihood that bears may cause adverse impacts on humans. in all, 321 bears were captured between may ... | 2015 | 25700042 |
