bluetongue and epizootic hemorrhagic disease in ruminants in georgia: survey by serotest and virologic isolation.the frequencies of precipitating antibodies to bluetongue virus (btv) and epizootic hemorrhagic disease virus (ehdv) in domestic ruminants and white-tailed deer (wtd) in georgia were 36% and 32%, respectively (n = 2,200). the frequencies of seropositivity to btv and ehdv were high among cattle (47% and 42%, respectively [n = 1,068]) and less so in wtd (36% and 34% [n = 414]). the frequencies among sheep were 34% for btv and 29% for ehdv (n = 286), whereas among goats, seropositivity was 8% for b ...19852998240
paralysis in swine due to focal symmetrical poliomalacia: possible selenium toxicosis.a paralytic disease in swine was observed on three farms located in the same geographical area of georgia. postmortem examinations revealed the paralysis to be related to spinal poliomalacia. feed collected from two of the affected farms was used in a feeding study, and the paralytic condition was reproduced. in pigs from both the feeding trial and field cases, the poliomyelomalacia was characterized by focal, symmetrical lesions located in the cervical and lumbar intumescences. selenium was det ...19836879953

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 ...200314690203
survey for vesicular stomatitis virus neutralizing antibodies in serums of white-tailed deer odocoileus virginianus of the southeastern united states.new jersey type vesicular stomatitis (vs) antibodies were found in 14 of 677 deer serums tested by neutralization tests in embryonated chicken eggs. twelve positive serums were received from louisiana and two from georgia. eight of the positive deer serums from louisiana were collected in the area of the only reported case of vs during 1967. clinical vs has not been diagnosed in the east coast states since 1964. two positive deer serums were collected on ossabaw island, georgia, and three positi ...197016512162
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 ...200717482368
fluke egg characteristics for the diagnosis of human and animal fascioliasis by fasciola hepatica and f. gigantica.in trematodiases, shape and size of the fluke eggs shed with faeces are crucial diagnostic features because of their typically reduced intraspecific variability. in fascioliasis, the usual diagnosis during the biliary stage of infection is based on the classification of eggs found in stools, duodenal contents or bile. the aim of the present study is to validate the identification of fasciola species based on the shape and size of eggs shed by humans, characterizing their morphometric traits usin ...200919375410
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 ...201020462700
synanthropic flies as vectors of cryptosporidium and giardia among livestock and wildlife in a multispecies agricultural complex.the capacity of synanthropic flies belonging to the families calliphoridae, sarcophagidae, and muscidae to serve as mechanical vectors of cryptosporidium and giardia among livestock and wildlife in a multispecies agricultural complex in northwest georgia (usa) was studied using fluorescent in situ hybridization (fish) and immunofluorescent antibody (ifa) techniques. flies from all three families were carrying viable cryptosporidium oocysts and giardia cysts internally and externally, and deposit ...200717979535
nonhuman remains and relics encountered by the medical examiner: fulton county, georgia, 2003-2004.medical examiner and coroner offices occasionally respond to "death scenes" which, after investigation, are found to involve nonhuman remains or other relics not requiring further investigation or certification of death. this report describes such cases encountered by the fulton county medical examiner during 2003 and 2004.200616936512
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 ...200415265575

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 ...200212403408
