Feces of 47 captive raptors belonging to the order Falconiformes or Strigiformes were cultured for bacteria. Gram-negative bacteria, which were cultured from the feces of 45 of the 47 raptors, were the most common isolates. A wide variety of species were identified, including a newly described genus (Moellerella wisconsensis), two newly described species (Escherichia fergusonii and Proteus penneri), and a member of a newly described enteric group (CDC Enteric group 41). Additional organisms identified that have not been reported in previous bacteriological surveys of raptors were Salmonella heidelberg, Salmonella braenderup, Morganella morganii, Yersinia ruckeri, Serratia spp., and Kluyvera sp. Escherichia coli, isolated from the feces of 42 of the 47 raptors, was the most frequently recovered. Streptococcus faecalis, the second most common isolate, was cultured from 30 birds. Several differences were observed between fecal bacteria isolated from raptors fed commercially prepared chicken and those isolated from raptors not fed chicken. The most obvious difference was that birds fed chicken had more varied gram-negative bacterial species and in greater numbers per fecal sample. The potential for the isolated bacteria from raptors as pathogens in humans and avian species is discussed.  相似文献   

Hypervitaminosis A in the dog.     

D Y Cho  R A Frey  M M Guffy  H W Leipold 《American journal of veterinary research》1975,36(11):1597-1603

Toxic effects of excessive vitamin A and of excessive vitamin ADE were studied in 9 mixed Labrador Retriever pups. Clinical signs were loss of body weight, dullness, emaciation, roughened coat, evident pain in limb joints, and retarded growth. Radiologic changes were decreases in overall length and thickness of long bones, development of osteophytes, periosteal reaction, and premature closure of epiphyses. Pathologic changes were degenerative epiphyseal plate, hemorrhage and exostotic proliferation of periosteum, fatty liver, and microcalculi in kidney. Toxic effects of excessive vitamin A did not appear to be so great when it was administered as vitamin ADE.  相似文献   

Effects of IgY antibody on the development of Marek's disease.     

V Kermani-Arab  T Moll  B R Cho  W C Davis  Y S Lu 《Avian diseases》1976,20(1):32-41

The effects of passive immunization with immunoglobulin Y (IgY) on the pathogenesis of Marek's disease (MD) were examined in an experimental line of White Leghorn chickens highly susceptible to MD. Purified IgY with anti-MDV antibody activity, when injected into chicks, delayed the development of MDV viremia and lesions until 9 days postinoculation (PI) with Marek's disease virus (MDV). The blastogenic response of spleen cells to concanavallin-A was depressed at 6 days PI in the birds without passive immunization, whereas it was not totally depressed until 17 days in birds passively immunized with IgY anti-MDV antibody.  相似文献   

Effect of NH₄⁺ Nitrogen on Phosphorus Uptake by Canola, Lentils, Soybeans and Wheat     

U. R. Sangakkara  C. M. Cho 《Journal of Agronomy and Crop Science》1987,159(3):199-201

Phosphorus and ammonium nitrogen placed together has been shown to increase P uptake by crops, especially cereals, Thus, the objective of this study was to compare this effect on four crops grown in Manitoba. Plants harvested at flowering indicated greater P uptake in lentils, soybean and wheat, when P and NH₄⁺-N were placed on the same band. In contrast, canola did not respond to this treatment. Possible relationships of these ions are presented.  相似文献   

Isolation of feline herpesvirus 1 from a young kitten     

R W Fulton  D Y Cho  M Downing  N J Pearson  R H Cane 《The Veterinary record》1980,106(23):479-481

Five kittens exposed neonatally to older cats exhibiting fever with nasal and ocular discharge became ill and died within 10 days of the onset of illness. One kitten which died at 16 days old was examined post mortem and feline herpesvirus 1 was isolated from the brain, liver, lung and spleen.  相似文献

Agenesis of corpus callosum in calves     

D Y Cho  H W Leipold 《The Cornell veterinarian》1978,68(1):99-107

Agenesis of the corpus callosum is a rare brain defect in cattle, and was described in two calves. It was characterized by the total absence of the corpus callosum, septum pellucidum and hippocampal commissure. Fornices were present but separated. Both calves also had moderate internal hydrocephalus, micrencephaly and a CSF-filled cyst in the longitudinal fissure dorsal to the thalamus. Clinical signs were not specific. Etiology and pathogenesis are unknown. No evidence of inflammation or inheritance was found as cause of the defect.  相似文献   

Perianal malignant melanoma in a dog     

Kim DY  Mauldin GE  Hosgood G  Cho DY 《Journal of veterinary internal medicine / American College of Veterinary Internal Medicine》2005,19(4):610-612

Melanocytic tumors are relatively common in dogs and most often occur in the oral cavity, lip, skin, digit, and eye. There are notable differences in the behavior of these tumors, depending on their anatomical location. The majority of oral melanomas and two-thirds of melanomas arising from the digit are malignant, whereas most of melanomas originating from the haired skin are benign. The anus and perianal areas are very uncommon sites for melanocytic tumors in domestic animals except horses, and most of those tumors in horses are malignant. To our knowledge, perianal malignant melanoma has not been reported in the dog and its prognosis is unknown.  相似文献   

Ultrasonic measurement of fetal parameters for estimation of gestational age in Korean black goats     

Lee Y  Lee O  Cho J  Shin H  Choi Y  Shim Y  Choi W  Shin H  Lee D  Lee G  Shin S 《The Journal of veterinary medical science / the Japanese Society of Veterinary Science》2005,67(5):497-502

The objective of this study was to determine relationship of gestational age with measurement of diameter of head, orbit, trunk, long and short axis of heart, aorta, placentome, umbilical cord and umbilical vein in Korean black goats. In this study, ten pregnant Korean black goats (Capra hircus aegagrus) were used. Pregnancy diagnosis was performed with a 5 MHz linear transducer and ultrasonographic scan were performed at 60, 75, 90, 105, 120 and 135 days after mating with a 4-9 MHz convex transducer. For accurate measurement, all fetal organs were measured at least 3 times. The diameter of head, orbit, trunk, long and short axis of heart, aorta, placentome, umbilical cord and umbilical vein were significantly increased with the gestational age (p<0.05). Of these parameters, trunk (r=0.8876; p<0.001), long axis of heart (r=0.9168; p<0.001) and short axis of heart (r=0.8819; p<0.001) proved to be the more effective measurements than other parameters, as it correlated well with gestational age. Results indicate that ultrasonic measurements of these parameters were useful methods to estimate gestational age in Korean black goat.  相似文献   

Congestive cardiomyopathy in a dog associated with pregnancy     

G E Sandusky  D Y Cho 《The Cornell veterinarian》1984,74(1):60-64

A two-year-old, six-week postpartum female dog was presented with acute congestive heart failure for treatment. The patient collapsed and suddenly died. Postmortem examination revealed an enlarged, dilated heart with thin ventricular walls. Histologically, scattered multifocal areas of myocardial degeneration and necrosis with fibrosis were seen in the myocardium. This case of acute cardiomyopathy in a female dog six weeks postpartum is similar to the well-described, postpartum cardiomyopathy in man. The etiology of this case was not ascertained.  相似文献
