Five mule deer fawns (Odocoileus hemionus) ranging in age from 3 to 6 weeks were given sporulated Eimeria mccordocki oocysts orally. Four of the five fawns developed coccidiosis. Initial clinical signs appeared by 8 to 9 days postinoculation and included elevated body temperature and bloody
Presumptive copper deficiency was diagnosed in hand-reared captive pronghorn (Antilocapra americana) at the Los Angeles Zoo. Clinical signs, which were manifested in growing fawns, included anemia, anorexia, diarrhea, progressive paresis/recumbency, and aortic rupture. The range of serum copper
Glutaraldehyde coagulation test, zinc sulfate turbidity test, and total protein refractometry were adapted for use in detecting failure of passive transfer of colostral immunoglobulins to mule deer fawns (Odocoileus hemionus). The results of all three tests were similar. Serum total protein
Bovine viral diarrhea virus (BVDV) is an important pathogen of domestic cattle. Serologic, experimental, and individual case studies explored the presence and pathogenesis of the virus in wild ungulates; however, there remain large gaps in knowledge regarding BVDV infection in nonbovine species.
During the 1990s, pronghorn (Antilocapra americana) populations declined in Arizona, USA. To investigate potential causes of decline, we collected blood samples from hunter-harvested male pronghorn from 2001 to 2003 on four Arizona sites. Sera were tested for antibody to parainfluenza virus type 3
Economic losses due to infection with Bovine viral diarrhea virus (BVDV) have prompted introduction of organized control programs. These programs primarily focus on the removal of persistently infected (PI) animals, the main source of BVDV transmission. Recently, persistent BVDV infection was
Mammalian orthoreovirus (MRV) is the type species of the genus Orthoreovirus and causes a range of significant respiratory, nervous or enteric diseases in humans and animals. In 2016 a farmed white-tailed deer (Odocoileus virginianus) fawn became ill, displaying clinical signs of lethargy,
The objective of the current study was to elucidate the within-host dynamics of bovine viral diarrhea virus (BVDV) type-1 infection to better understand how this virus could be maintained in white-tailed deer (Odocoileus virginianus, WTD) populations. The BVDV type-1 used in this study was
Necropsy of 2 white-tailed deer fawns who died acutely revealed diarrhea and melena in case No. 1 and no gross changes in case No. 2. Histologically, the livers of both deer displayed multifocal coagulative necrosis, with infiltrations of neutrophils, macrophages, and lymphocytes. By Warthin-Starry
OBJECTIVE
To assess the transmission of bovine viral diarrhea virus (BVDV) from experimentally infected white-tailed deer fawns to colostrum-deprived calves by use of a BVDV strain isolated from hunter-harvested white-tailed deer.
METHODS
5 white-tailed deer (Odocoileus virginianus) fawns and 6
Although commonly associated with infection in cattle, bovine viral diarrhea viruses (BVDV) also replicate in many domestic and wildlife species, including cervids. Bovine viral diarrhea viruses have been isolated from a number of cervids, including mule deer (Odocoileus hemionus), European roe deer
Reovirus-like particles were demonstrated by negative stain electron microscopic examination of the feces from antelope fawns with diarrhea. Fluorescent antibody tests on frozen sections of ileum from one dead antelope fawn and immunoelectron microscopy tests on feces from two live fawns provided
In order to determine the susceptibility of deer to infection with bovine viral diarrhea virus (BVDV), four mule deer (Odocoileus hemionus) fawns and one white-tailed deer (O. virginianus) fawn were inoculated intranasally with the New York-1 strain of BVDV originally isolated from cattle. None of
OBJECTIVE
To inoculate white-tailed deer (Odocoileus virginianus) during the sixth or seventh week of gestation with bovine viral diarrhea virus (BVDV) and observe for signs of reproductive tract disease during a 182-day period.
METHODS
10 pregnant white-tailed deer (8 seronegative and 2
Cattle persistently infected (PI) with bovine viral diarrhea virus (BVDV), a pestivirus in the family Flaviviridae, are an important source of viral transmission to susceptible hosts. Persistent BVDV infections have been identified in white-tailed deer (Odocoileus virginianus), the most abundant
