Ectopic ureters in a male cat.

A 16-week-old male cat with urinary incontinence was initially diagnosed as having a right ectopic ureter. Other abnormalities of the urinary system included phimosis, hydronephrosis, and localized right megaloureter. Surgical removal of the right kidney and right ureter was partially successful in stopping the urinary incontinence. Further radiographic studies and retrospective examination of initial radiographs revealed that the left ureter was also ectopic.

Tuberculin sensitivity in a high-risk canine population.

An epidemiologic study of tuberculosis in dogs exposed to humans with recently reported tuberculosis was undertaken in Philadelphia between July 1966 and June 1968. A total of 29 dogs meeting the criteria for inclusion in the high-risk population were studied by history, physical examination, intradermal tuberculin tests, and radiographic and bacteriologic examination. Ten of the 29 dogs showed positive responses to US Department of Agriculture (USDA) standard mammalian tuberculin. Positive tuberculin tests to second strength PPD were demonstrated in five of the 10 responders to USDA mammalian tuberculin. No physical, radiographic or bacteriologic evidence of tuberculosis was found in any of the high-risk animals examined. In a comparison group of 70 dogs without knwon exposure to tuberculosis, two positive responses to USDA tuberculin were demonstrated and none to PPD.

Enhancement of St. Louis arbovirus plaque formation by neutral red.

Experiments with St. Louis encephalitis (SLE) virus have shown that neutral red enhances the plaque size in duck embryo cell cultures. This may represent a new method for genetic studies of SLE virus population. In a mosquito pool specimen NR(+) and NR(-) particles were demonstrated. By intracerebral passage in mice, there is a selection of NR(+) particles. Similar effects were not shown for eastern, western, and California encephalitis viruses. Plaques formed by the latter virus, however, were significantly reduced in number by neutral red.
