Since the introduction of vaccinia by Jenner 200 years ago, vaccines have been the first line of defense in controlling infectious diseases in man and domestic animals. Large scale domestic dog vaccination programmes against canine distemper virus (CDV) and canine adenovirus (CAV) became possible in the late 1940’s, when egg-adapted vaccines became available on a commercial basis, followed by t...

Many authors have entertained the possibility, mainly on epidemiological grounds, that multiple sclerosis is a consequence of a disease acquired in childhood (1). Among the number of common childhood infectious agents that have been impliacted in this disease, viral agents, in particular the paramyxoviruses, cccupy a prominent place as possible etiological agents. First, a number of studies hav...

Canine distemper virus (CDV) was previously considered to have a host range restricted to the canid family. In 1994, the virus was associated with sporadic outbreaks of distemper in captive felids. However, after severe mortality occurred in the Serengeti lions (Panthera leo), attention became focused on the pathogenesis of the virus and a concerted effort was made to identify the virus as CDV ...

Benzalkonium chloride (as Roccal or Zephiran) was found to inactivate influenza, measles, canine distemper, rabies, fowl laryngotracheitis, vaccinia, Semliki Forest, feline pneumonitis, meningopneumonitis, and herpes simplex viruses after 10 min of exposure at 30 C or at room temperature. Poliovirus and encephalomyocarditis virus were not inactivated under the same conditions. It was concluded ...

A radioimmunoprecipitation-polyacrylamide gel electrophoresis technique was applied to sera from canine distemper virus-infected dogs. Sera from fatally infected dogs precipitated only the nucleoprotein, the matrix protein, and trace amounts of fusion glycoprotein. Sera from normal convalescent dogs precipitated all five major polypeptides. In contrast, sera from persistently infected dogs were...

Measles and canine distemper viruses were grown together in a Vero monkey kidney cell line. Each virus could be identified and individually titrated by using the color contrast produced by the reddish tetra-methyl rhodamine isothiocyanate-tagged antimeasles conjugate and the green fluorescein isothiocyanate-tagged antidistemper conjugate. Both blue light and green light were used for the excita...

Canine infectious respiratory disease complex (CIRDC) viruses have been detected in dogs with respiratory illness. Canine influenza virus (CIV), canine parainfluenza virus (CPIV), canine distemper virus (CDV), canine respiratory coronavirus (CRCoV), canine adenovirus type 2 (CAdV-2) and canine herpesvirus 1 (CaHV-1), are all associated with the CIRDC. To allow diagnosis, two conventional multip...

The National Insurance Act of 1911 provided, by creating the Medical Research Committee, explicit government support for experimental, scientific medicine. This official gesture was made against a background of concern about some of the methods of scientific medicine, especially the use of living animals in medical research. Organized protests against animal experiments had gathered strength du...

The highest incidence of Paget's disease is in the United Kingdom and is lower in other European countries. Worldwide the incidence appears to be decreasing. Some countries have observed a reduction in the severity at presentation, perhaps reflecting changes in migration of the UK population. Evidence of a genetic susceptibility to Paget's disease is accumulating, with chromosome 6 (the HLA loc...

A strain of camel kidney cells was developed and carried in serial passages. The subcultures were slow-growing in the early passages and were composed of heterogeneous cell population. By the 35th passage, the growth rate increased, and more homogeneous cells, mostly of the epithelioid type, were seen. The cell strain was highly susceptible to West Nile, Sindbis, vesicular stomatitis, adeno, an...
