[Reovirus infection of pheasants (Phasianus colchicus)]. / Reovirusinfektion von Fasanen (Phasianus colchicus).

In this case report we discribe clinic, pathology and diagnostic of an avian reovirus-infection in pheasants. The disease was observed 1993 in a flock of game-pheasants in the western part of Turkey. Of a live-stock of 100 animals, 27 were affected most of them being three to five months old. Beside a general disorder, sick pheasants showed signs of shortness of breath as well as greenish, watery diarrhoea and died within a week. The pathologic findings were dominated by an extreme hepatopathia. In addition a fibrinous tracheitis, a catarrhal inflammation of the gut and a perihepatitis fibrinosa could be observed. From organs of affected pheasants a pathogen could be isolated, which was characterized anti-genetically, by physico-chemical properties an by electronmicroscopy as avian reovirus.

[Proventriculitis in domestic fowl (Gallus gallus var. dom. L., 1758) caused by megabacteria]. / Eine durch Megabakterien verursachte Drüsenmagenentzündung beim Haushuhn (Gallus gallus var. dom. L., 1758).

Three cases of a disease similar to going light syndrome in budgerigars in a flock of young laying hens in Turkey are reported. In all cases megabacteria in association with E. coli could be isolated. The causing agent appeared to be large, rod-shaped, gram-positive or gram-labil, and catalase test positive bacteria with cytochromoxydase activity. Subcultivation of these bacteria could not be achieved.

[Biochemical properties of avian Citrobacter amalonaticus strains]. / Biochemische Eigenschaften aviärer Citrobacter amalonaticus-Stämme.

A report is given on the biochemical properties of C. amalonaticus-strains of avian origin. Some strains show decisive deviations of the "norm", usually established from mammalian strains and details are given in a table. The results are discussed and the strains considered to be avian specific.

[The pharmacokinetics of dihydrostreptomycin sulfate in domestic pigeons (Columba livia Gmel., 1789 var. domestica)]. / Zur Pharmakokinetik von Dihydrostreptomycinsulfat bei Haustauben (Columba livia Gmel., 1789 var. domestica).

A 20% aqueous solution of dihydrostreptomycin sulfate in a dosage of 100 mg/kg b.w. is non-toxic for pigeons, although renal accumulation occurs. 12 hours after a single subcutaneous injection of 100 mg/kg b.w. the plasma concentration decreases to 3.64 micrograms/ml and therefore below the therapeutically effective concentration, while in birds suffering from salmonella infections plasma levels decrease to comparative concentrations (3.84 micrograms/ml) after only 8 hours. Contrary to the directions for use in pigeons of the preparation CX 60, the subsequent dosage should be given no later than 10 hours after the first application.
