natural and experimental infection of white-tailed deer (odocoileus virginianus) from the united states with an ehrlichia sp. closely related to ehrlichia ruminantium.an ehrlichia sp. (panola mountain [pm] ehrlichia sp.) closely related to ehrlichia ruminantium was recently detected in a domestic goat experimentally infested with lone star ticks (lsts, amblyomma americanum) collected from georgia, usa. the infected goat exhibited pyrexia and mild clinical pathologic abnormalities consistent with ehrlichiosis. at least two other ehrlichia species (ehrlichia chaffeensis and ehrlichia ewingii) are maintained in nature by a cycle involving lsts as the primary vec ...200818436670
rabies surveillance in the united states during 2006.during 2006, 49 states and puerto rico reported 6,940 cases of rabies in animals and 3 cases in humans to the cdc, representing an 8.2% increase from the 6,417 cases in animals and 1 case in a human reported in 2005. approximately 92% of the cases were in wildlife, and 8% were in domestic animals. relative contributions by the major animal groups were as follows: 2,615 raccoons (37.7%), 1,692 bats (24.4%), 1,494 skunks (21.5%), 427 foxes (6.2%), 318 cats (4.6%), 82 cattle (1.2%), and 79 dogs (1. ...200717696853
multiple anthelmintic resistance in a goat herd.anthelmintic resistance was monitored over a 30 month period within a goat herd in eastern virginia, usa. resistance to ivermectin, levamisole and benzimidazole drugs was detected in haemonchus contortus using the fecal egg count reduction test (fecrt). when levamisole use was discontinued for 1 year, susceptibility to levamisole appeared to return. although a single treatment with fenbendazole was able to reduce fecal egg counts by only 50%, two doses administered in a 12 h interval increased e ...200010622608

serologic evidence of jamestown canyon and keystone virus infection in vertebrates of the delmarva peninsula.serological data accumulated during the past decade indicated that a variety of feral and domestic animals of the delaware-maryland-virginia (delmarva) peninsula were infected with jamestown canyon (jc) and/or keystone (key) viruses (bunyaviridae, california serogroup). neutralizing (n) antibody to jc virus was most prevalent in white-tailed deer, sika deer, cottontail rabbits and horses. key virus n antibody was detected most frequently in gray squirrels and domestic goats. n antibody indicativ ...19827149110

detection of salmonella strains and escherichia coli o157:h7 in feces of small ruminants and their isolation with various media.salmonella strains and escherichia coli o157:h7 were detected in 17 and 5 small ruminants in virginia, respectively, of 287 tested. background microflora interfered with the fecal analysis. the combination of salmonella enzyme immunoassay (eia) detection and xylose-lysine-deoxycholate agar isolation was satisfactory. modifying enrichment to a 1:100 dilution enabled effective e. coli o157:h7 detection by eia and isolation by sorbitol-macconkey agar with cefixime-tellurite.200515812051

absence of la crosse virus in the presence of aedes triseriatus on the delmarva peninsula.between 1980 and 1984, field studies were conducted in 2 areas on the delmarva peninsula to identify the presence of la crosse (lac) virus. ovitraps were used to collect eggs of aedes triseriatus complex mosquitoes. no virus was obtained from 969 pools containing 22,370 adult mosquitoes reared from eggs. only 1 of 143 raccoon serum samples had neutralizing antibody to lac virus; 36 sentinel domestic goats, and 99 other wild mammal serum samples were negative. the apparent absence of lac virus ma ...19863507467
