[Usefulness of the determination of serum lysozyme levels in dogs with tumors].

In a control group of fifty-three clinically healthy dogs of either sex and ranging in age from four to ten years, the serum lysozyme activity (SLA) showed a mean value of 1.2 mg/l with a range (+/- 2 SD) of 0.6-1.8 mg/l. SLA was measured in a turbidimetric assay using a microcentrifugal analyser. In dogs with a variety of neoplastic diseases, the histopathological diagnosis was compared with the SLA-level. In a large number of cases, the increased SLA-levels corresponded with malignancy in neoplastic disease. Measuring the SLA-level in dogs may be helpful in the diagnosis of malignancies. Proper clinical examination is essential in differentiating between some interfering diseases.

[A cow with an extremely prolonged gestation period].

Gestation continued for 324 days in a cow pregnant for the fourth time. This extreme prolongation could be due to congenital abnormality in the calf consisting in aplasia of the pituitary and anencephaly.

[Use of various methods of sampling and various culture media in the isolation of Bordetella bronchiseptica from swine in the field (author's transl)].

During eleven visits to nine pig-breeding farms and multiplying herds, 190 piglets were sampled by three different methods. The nares were separately sampled and both nares were sampled with a single swab. Three media were used to discover which method and which medium produced the highest isolation-score for Bordetella bronchiseptica (BB). The CDI-Mac Conkey (McC-CDI) plate was used as a reference medium and was compared with the Gezondheidsdienst Mac Conkey (McC-GD) and the new Bordetella plate (Bord.pl). Of the 570 samples collected 303 were positive for Bordetella bronchiseptica. When the McC-CDI BB was used, the score was 286, when the McC-GD was used, it was 264 and when the Bord.pl. was used 277, and BB was present on each of the three plates in 243 cases. When both nares of each piglet were separately sampled, 94 per cent, 87 per cent and 85 per cent of the BB positive-piglets were found to be positive with respectively McC-CDI, McC-GD and the Bord.pl. Sampling each nare with one swab, produced an average BB score of approximately 80 per cent and both nares with a single swab approximately 85 per cent of the BB-positive pigs. Statistical testing showed the McC-CDI to be significantly (P = 0,05) superior to the Bord.pl.

Phenylmercuric acetate intoxication in mink.

Mink died following an incidental phenylmercuric acetate (PMA) intoxication. Mortality was restricted to the older animals (31% in the females and 40% in the males). Of all organs the kidneys were most seriously damaged (tubulonephrosis) and contained the highest residual levels of mercury. No lesions were observed in the central nervous system. Twenty-one weeks after exposure mercury residues had declined to normal levels. The half-time of disappearance of mercury was 10 days in skeletal muscle, 22 days in kidneys, 27 days in brain and 36 days in liver. The reproductivity of the surviving mink was not affected by the PMA-intoxication.

[Disease and causes of death in birds (authors transl)].

In 1975, post-mortem studies were done on 745 birds. The findings are tabulated. The most important problems are evaluated. The most striking finding is the very large proportion (46.0 per cent) of birds which died from infectious disease caused either by bacteria, viruses, protozoa or parasites. Hygiene is stressed as a valuable preventive measure.

Yersinia pseudotuberculosis in birds.

245 Avian strains of Yersinia pseudotuberculosis were isolated over a period of 18 years (1958-1975. Toucans appear to be highly susceptible to pseudotuberculosis. The number of isolates was highest in the colder months (December-March). Serotype 1 was isolated most frequently. There were no essential differences among the five serotypes in sensitivity to chemotherapeutics.

Bone structures in avian and mammalian lungs.

Ectopic bone was found in the interstitium of lungs of birds, guinea pigs and minks. There was no evidence of a relation between the ectopic bone and the occurrence of disease.
