Neutralizing antibody response in bovine serum and nasal and salivary secretions after immunization with live or inactivated food-and-mouth disease virus.

Calves develop nasal and salivary neutralizing antibodies against foot-and-mouth disease virus after nasal inoculation with live virus. Nasal and salivary antibody was not detected after exposure to inactive virus. Serum antibodies were induced by live and inactive virus given subcutaneously. Passively acquired antibodies were detected as long as 7 months after birth.

Fish trypanosomes: their position in kinetoplastid phylogeny and variability as determined from 12S rRNA kinetoplast sequences.

Fish trypanosomes have traditionally been classified according to the host species from which they were isolated, each isolate being regarded as a distinct species. To test the soundness of this practice, the genetic variabilities of the kinetoplast 12S rRNA-encoding genes of different fish trypanosomes isolates were compared. The DNAs were extracted from trypanosomes cloned from blood samples of 15 donors representing ten different fish species in four orders from waters of three major river systems of Central and Northern Europe. Comparison with other trypanosomatid sequences revealed that the fish trypanosomes form a monophyletic group with Trypanosoma brucei as a sister group. Pairwise comparisons of genetic distances yielded a wide range of continuous variation with no indication of any discontinuities attributable to barriers to gene flow. The genetic distances did not correlate with either the identity of the host species or geography. The host specificity of fish trypanosomes appears to be limited.

[A case of posterior thyroid ophthalmopathy following neck irradiation].

OBJECTIVE: To report a case of a patient who developed a Graves' ophthalmopathy class III two weeks after receiving radiotherapy in the neck. CASE HISTORY: He was a male of 51 years of age with a stage IIIB Hodgkin's disease who received chimio- and radio-therapy two weeks previous to the ophthalmopathy. The computed axial tomography showed retroorbital changes. The thyroid function tests, including the stimulation with thyrotropin releasing hormone and the microsomal and thyroglobulin antibodies were normal. The patient was treated with oral prednisone, followed by retroocular radiotherapy on the right eye. The exophthalmos improved and the diplopia disappeared.
