efficacy of anthelmintics on south american camelid (llama and alpaca) farms in georgia.	the number of south american camelid (sac; llama and alpaca) farms is growing in the southeastern united states, and infection with gastrointestinal nematodes (gin) is a major health concern in this region. there is widespread resistance to anthelmintic remedies in small ruminants (sheep and goats), but a paucity of information on llamas and alpacas. anthelmintic resistance was evaluated on three sac farms (two llama; one alpaca) in georgia in the southern united states using fecal egg count red ...	2010	20462700
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 ...	2008	18436670
accuracy of the famacha system for on-farm use by sheep and goat producers in the southeastern united states.	famacha is a practical on-farm system designed to provide small ruminant producers a tool for improving their management of haemonchus contortus infections. although this system has become very popular and widely accepted by small ruminant producers in many regions of the southern united states, there is very limited data reported on the effectiveness of the famacha system when performed by farmers. the objective of this study was to evaluate the accuracy of the famacha system for on-farm use by ...	2007	17482368
infection of a goat with a tick-transmitted ehrlichia from georgia, u.s.a., that is closely related to ehrlichia ruminantium.	we detected a novel tick-transmitted ehrlichia in a goat following exposure to lone star ticks (amblyomma americanum) from a park in the metropolitan area of atlanta, ga, u.s.a. nineteen days after infestation with field-collected adult ticks, the goat developed a fever of two days duration, which coincided with mild clinical pathologic changes and the presence of dna from a novel ehrlichia in peripheral blood. the goat transmitted ehrlichiae to uninfected nymphal a. americanum that fed upon the ...	2006	17249337
validation of the famacha eye color chart for detecting clinical anemia in sheep and goats on farms in the southern united states.	recent studies on sheep and goat farms in the southern united states indicate that multiple-anthelmintic resistance in haemonchus contortus is becoming a severe problem. though many factors are involved in the evolution of resistance, the proportion of the parasite population under drug selection is believed to be the single most important factor influencing how rapidly resistance develops. therefore, where prevention of resistance is an important parallel goal of worm control, it is recommended ...	2004	15265575
capability of the nematode-trapping fungus duddingtonia flagrans to reduce infective larvae of gastrointestinal nematodes in goat feces in the southeastern united states: dose titration and dose time interval studies.	infection with gastrointestinal nematodes, particularly haemonchus contortus, is a major constraint to goat production in the southeastern united states. non-anthelmintic control alternatives are needed due to increasing resistance of these nematodes to available anthelmintics. two studies were completed in central georgia in august 1999, and april-may 2000, using spanish does naturally infected with haemonchus contortus, trichostongylus colubriformis, and cooperia spp. to evaluate effectiveness ...	2004	15063939
rabies surveillance in the united states during 2002.	during 2002, 49 states and puerto rico reported 7,967 cases of rabies in nonhuman animals and 3 cases in human beings to the centers for disease control and prevention, an increase of 7.2% from the 7,436 cases in non-human animals and 1 case in a human being reported in 2001. more than 92% (7,375 cases) were in wild animals, whereas 7.4% (592) were in domestic species (compared with 93.3% in wild animals and 6.7% in domestic species in 2001). compared with cases reported in 2001, the numbers of ...	2003	14690203

q fever--california, georgia, pennsylvania, and tennessee, 2000-2001.	q fever is a zoonotic disease caused by the bacterium coxiella burnetii. the most common reservoirs are domesticated ruminants, primarily cattle, sheep, and goats. humans acquire q fever typically by inhaling aerosols or contaminated dusts derived from infected animals or animal products. its highly infectious nature and aerosol route of transmission make c. burnetii a possible agent of bioterrorism. although up to 60% of initial infections are asymptomatic, acute disease can manifest as a relat ...	2002	12403408
multiple animal intoxications associated with carolina jessamine (gelsemium sempervirens) ingestions.	neurological signs characterized by marked progressive weakness and convulsions culminating in death were observed in 3 goats over a 24-h period. affected animals were in a group of 5 goats confined toa fenced paddock: a domestic goose within the paddock was also found dead. present in the same paddock, but unaffected, were 2 other goats and an adult cow. five days prior to the animals' deaths, the owner had trimmed the surrounding brush and had thrown the cuttings into the enclosure. post morte ...	2002	12361108
anthelmintic resistance on goat farms in georgia: efficacy of anthelmintics against gastrointestinal nematodes in two selected goat herds.	gastrointestinal nematode (gin) parasitism is a major constraint to production of goats in the southeastern united states. the conventional method of control used by producers in this region is frequent use of anthelmintics during the warm season. overuse of anthelmintics has led to an increase in the incidence of anthelmintic resistance in many parts of the world, but data on prevalence of anthelmintic resistance in gin of goats in the southeastern united states are very limited. to address thi ...	2001	11390079
natural infection of domestic goats with ehrlichia chaffeensis.	thirty-eight domestic goats from an area of ehrlichia chaffeensis endemicity were tested for antibodies reactive to e. chaffeensis and for e. chaffeensis-specific 16s rrna gene fragments by an indirect fluorescent antibody test and a nested pcr assay, respectively. twenty-eight of 38 (73.7%) goats had antibodies reactive to e. chaffeensis (>/=1:128), and 6 of 38 (15.8%) goats were positive by diagnostic pcr; e. chaffeensis was isolated in cell culture from one goat. our data indicate that goats ...	2000	10618139
