Induction of immunity against infection with Theileria parva (East Coast fever) in cattle using plasma membranes from parasitized lymphoblasts     

D L Emery  W I Morrison  R M Jack 《Veterinary parasitology》1986,19(3-4):321-327

Protection against challenge with Theileria parva was conferred on three of four calves given three or four inocula of plasma membranes prepared from 6 to 12 X 10(8) autologous parasitized lymphoblasts from cultured cell lines. In contrast, calves remained susceptible to infection following immunization with membranes prepared from allogeneic parasitized lymphoblasts. Similarly, calves vaccinated with either gamma-irradiated autologous or allogeneic infected cells also died of East Coast fever after challenge. The results raise the possibility of vaccination against T. parva using subcellular material from infected lymphoblasts.  相似文献   

Spread of pseudorabies virus among breeding swine in quarantined herds.     

S J Duffy  R B Morrison  D G Thawley 《Journal of the American Veterinary Medical Association》1991,199(1):61-65

In theory, pseudorabies virus (PRV) may be eliminated from any size of breeding herd by phased test and removal if replacement gilts are not infected with PRV, culling decisions are partially based on PRV status, and the cull rate is higher than the incidence rate of PRV. Annual cull rates are commonly at least 50%, but little information exists on the incidence of PRV within enzootically infected swine herds. The purpose of this study was to develop a method by which spread of PRV could be detected among breeding swine within enzootically infected herds and to determine the incidence of PRV infection in these herds. Data were collected from 17 herds that were quarantined for PRV and ranged in size from 120 to 1,100 sows. At each herd, within the first 5 days of introduction, a group of approximately 30 replacement gilts was identified, vaccinated with a glycoprotein X-deleted PRV vaccine, and blood sample was collected. The owner of 1 herd had a nonvaccinated breeding herd and elected to leave incoming gilts nonvaccinated. After vaccination, blood samples were collected every 1 to 2 months for an average of 13.6 months. Serum samples from vaccinated gilts were tested for antiglycoprotein X antibodies by a specific differential ELISA. Samples from nonvaccinated gilts were evaluated by serum neutralization test. Product-limit method was used to estimate the probability of not becoming infected with PRV. Spread was detected in 7 of 8 herds that had more than 400 sows and in 2 of 9 herds that had less than 400 sows.(ABSTRACT TRUNCATED AT 250 WORDS)  相似文献   

Differential diagnosis and management of human-directed aggression in cats.     

Diane Frank  Joel Dehasse 《Veterinary Clinics of North America: Small Animal Practice》2003,33(2):269-286

Human-directed aggression in cats should be evaluated as a multifactorial problem. It results from the combined actions of heredity, environment, learning, human social requirements (or needs), client interactions, lack of understanding of normal feline behavior, unrealistic client expectations, and lack of meeting the cat's basic ethologic needs. Managing human-directed aggression in cats encompasses the use of environmental modification, therapies, and, when and if needed, regulatory drugs so as to increase learning capabilities and adaptation and decrease danger to the human victims.  相似文献   

Hypersomatotropism and insulin-resistant diabetes mellitus in a cat   总被引：1，自引：0，他引：1  

S A Morrison  J Randolph  C D Lothrop 《Journal of the American Veterinary Medical Association》1989,194(1):91-94

In this report, we described the clinical, radiographic, and echocardiographic findings in a cat with hypersomatotropism and insulin-resistant diabetes mellitus. Growth hormone determinations were made because of persistent hyperglycemia despite insulin requirements exceeding 2.2 U/kg of body weight, and the acromegalic features of the cat. Also, the results of a therapeutic trial in which a long-acting analogue of somatostatin was used are discussed.  相似文献   

The Microanatomy of the Coyote's (Canis latrans) Respiratory System     

E. E. Morrison    H. W. Leipold  S. M. Kruckenberg 《Anatomia, histologia, embryologia》1983,12(4):325-340

A Light, scanning and transmission electron microscopic study of the coyote respiratory system was carried out, utilizing ten coyotes of both sexes. The animals ranges in age from 8 to 24 months and were in good health. Comparison of the respiratory tissues of the coyote with other Canid species are made.  相似文献

Primary Ciliary Dyskinesia in the Dog   总被引：1，自引：0，他引：1  

Wallace B. Morrison DVM    Norman J. Wilsman DVM  PhD    Leslie E. Fox DVM  Cornelia E. Farnum DVM  PhD 《Journal of veterinary internal medicine / American College of Veterinary Internal Medicine》1987,1(2):67-74

Electron microscopy was used to diagnose primary ciliary dyskinesia in a litter of English pointer dogs and in a golden retriever dog. A technique of membrane solubilization, fixation, and negative staining with glutaraldehyde tannic acid identified abnormally constructed central and B microtubules in respiratory cilia from dogs with primary ciliary dyskinesia. Shortened outer dynein arms commonly associated with primary ciliary dyskinesia actually represents the absence of a specific subset of the three most peripheral components of the whole outer dynein arm structure.  相似文献   

Differential inhibition of potassium ion absorption by difenzoquat in wild oat and cereals     

A.S. Cohen  I.N. Morrison 《Pesticide biochemistry and physiology》1982,18(2):174-179

Over a concentration range of 5.0 × 10^?6?7.5 × 10^?4M, the selective herbicide difenzoquat (1,2-dimethyl-3,5-diphenyl-1H-pyrazolium) caused more pronounced inhibition of potassium ion (K⁺) absorption by excised seedling roots of susceptible wild oat (Avena fatua L.) compared to those of tolerant barley (Hordeum vulgare L. cv. Bonanza) or wheat (Triticum aestivum L. cv. Neepawa). At 2.5 × 10^?5M difenzoquat, the relative inhibition of K⁺ (⁸⁶Rb) absorption by wild oat root segments inceased from 30% with a 10-min uptake period to 75% with an uptake period of 90 min, whereas no inhibition at all was evident for wheat root segments even after a 90-min exposure to the herbicide. An ion efflux compartmental analysis procedure demonstrated that difenzoquat did not affect the passive permeability properties of the plasma membrane of wild oat root cells. The experimental findings indicated that difenzoquat interfered directly with the process of active ion transport across the plasma membrane of root cells.  相似文献
