The efficacy of a live Listeria monocytogenes combined serotype 1/2a and serotype 4b vaccine.

In each of two experiments, sheep and lambs were vaccinated by a subcutaneous injection of a test vaccine (consisting of a combined serotype 1/2a and serotype 4b live Listeria monocytogenes culture) and challenged 16 days later with a mixture of the homologous wild strains. After challenge, the mortality rate of vaccinated sheep was 28.1% and that of controls 71.9%; that of lambs was 25.0%, although these had been inoculated with the LD70 dose. Furthermore, in each of two field trials in Listeria-infected flocks, primiparous pregnant ewes were vaccinated. In the first field trial, 3 or 110 lambs died of listeriosis of those born of vaccinated (n = 564) or unvaccinated (n = 3345) ewes, respectively. In the second, the perinatal mortality rate of lambs born of vaccinated or unvaccinated ewes was 7.6 or 30.3%, respectively, and the mean birth weight of lambs born of vaccinated or control ewes was 2.2 or 1.8 kg, respectively; the mean milk production of vaccinated ewes was 106 and that of controls 83 l; no Listeria was isolated from milk samples of vaccinated ewes. It is concluded that the vaccine is efficacious for the protection of sheep from listeriosis.

[The pathology and pathogenesis of experimental Mycoplasma hyorhinis infection of piglets with and without thermomotoric stress. 1. Pathologico-anatomic, histologic and immunomorphologic study results].

The effect of an experimental Mycoplasma (M.) hyorhinis infection (3 times intranasal instillation of 3-5 ml bouillon with 10(7) Colony forming units [CFU]/ml) in combination with a standard thermomotoric stress (swim-test) was studied in piglets using pathomorphological, immunomorphological and microbiological methods. The 92 piglets were divided into the following 5 groups: swimmers with infection (S-I; n = 19); swimmers without infection (S; n = 19); control piglets with infection (K-I; n = 21); controls without infection, but direct (K1; n = 16) or indirect contact (K2; n = 17) with experimentally infected animals. The experimental or spontaneous infection (direct or aerogenous infection) with M. hyorhinis caused in 30.4% of the piglets an acute or subacute, catarrhal-purulent bronchopneumonia with an interstitial component. Incidence and intensity of pneumonia were significantly higher in the groups with thermomotoric stress (independent from the mode of infection) than in the non-stressed groups. The M. hyorhinis pneumonia was characterized by a limited expansion and a trend to restitution. The causal agent (M. hyorhinis) was demonstrated with immunomorphological methods (immunofluorescence and PAP) in the ciliary zone of the nasal, tracheal and especially on the bronchial mucosa, and occasionally in the bronchioles and alveoli.

[The pathology and pathogenesis of experimental Mycoplasma hyorhinis infection of piglets with and without thermomotor stress. 2. Electron microscopic study results].

Electron microscopic investigations on the respiratory tract of piglets with and without Mycoplasma hyorhinis infection (10th day of life) partly combined with swim stress (15 degrees C water temperature) (n = 20/20) yielded the following results: colonization of Mycoplasma hyorhinis in the ciliary zone of trachea and bronchi in 15 out of 40 piglets (37.5%); the evidence rate of Mycoplasma hyorhinis in pneumonic lungs (8 out of 12 = 66.7%) was significantly higher than in nonpneumonic lungs (7 out of 28 = 25.0%) and highest in experimentally infected piglets with swim stress (9 out of 16 = 56.2%). Ultrastructural lesions: loss of cilia; bleb-formation; hydropic degeneration and desquamation of ciliary cells; the occurrence of cilia-free and immature epithelial cells; alveolar collapse; microatelectasis; oedematous swelling of pneumocyte I; accumulation of surfactant in the alveoli; hyperplasia of pneumocyte II; exudation of mononuclear macrophages and neutrophils with numerous digestion vacuoles; several lymphocytes and plasma cells, only a little lymphohistiocytic interstitial and peribronchial infiltration. Phagocytized mycoplasmas were found within the resorption vacuoles of neutrophils in the tracheobronchial area, for this once in alveoli, not (more) against in alveolar macrophages. The results were discussed with regard to etiology and pathogenicity of enzootic pneumonia in pigs.

[Clinical results of the goniothrephining with scleral flap (author's transl)].

During 1971-1976 407 goniotrephinings e.g. "Elliot with scleral flap", were performed at the Univ. Eye Hospital Münster. In a follow-up study of 306 operated cases we found 81% primary glaucoma (62.7% simple glaucoma, 18.3% chronic congestive glaucoma) and 19% secondary glaucoma. In 77% of the operated cases the anterior chamber was restored within the first postoperative day. Gonioscopically in 85% the trephining hole was placed within the trabecular meshwork. Nevertheless, this position of the hole had no decisive influence on the later filtration. Postoperatively 2/3 of cases developed a characteristic flat filtering bleb. In 90.4% of the eyes the postoperative IOP was within normal limits. Postoperative follow-up of the visual acuity remained within the limits of age deterioration. Concerning the secondary glaucoma, the pigmentary glaucoma, the traumatic glaucoma and the glaucoma after uveitis, had good results. The results in cases of buphthalmos and hemorrhagic glaucoma were worse. The advantages of goniotrephining are the rapid restoring of the anterior chamber, the protection of the trephining hole by the scleral flap as well as the well "protected" flat and infections-resisting bleb.

Ventricular septal defect in a houbara bustard (Chlamydotis undulata macqueenii).

A ventricular septal defect was found in a juvenile captive-bred houbara bustard (Chlamydotis undulata) that died suddenly. The case history indicated that the bird had a retarded growth and maturation rate. Gross pathology demonstrated massive internal hemorrhage, an enlarged heart with an interventricular septal defect, one shrunken liver lobe, and hypoplastic kidneys. Histologically, the liver was characterized by fatty degeneration, and there was hydropic degeneration of the cardiac muscle fibers. We suggest that the occurrence of this defect led to cardiac insufficiency, which resulted in sudden death caused by hemorrhage from the liver.
