Opis:
The study analyses accident rate in the Regional Directorate of the State Forests in Szczecinek (NW Poland) in the years 1990−2009. 1042 accidents occurred in the analyzed period. The frequency rate equalled to 14.75, i.e. almost 15 accidents per 1000 employees. The severity rate amounted 48.65. The analysis showed that privatization of forest works did not have significant impact on accident rates.

Opis:
Experiments were carried out on 150 sheep of different race, age and sex, designed for slaughter. Coproscopis examination helped to reveal in them infestation with Fasciola hepatica and gastro-intestinal nematodes. About 100/o of the sheep were also infested with pulmonary nematodes. 50 sheep were administered per os Zanil, 50 - Nilzan, and 50 made the control group. Post-mortem parasitological examinations helped to arrive at following conclusions: Zanil appeared to be a highly effective preparation against F. hepatica in sheep, giving 1000/o control of mature forms of the parasite. Similarly effective on F. hepatica was Nilzan, which also showed an action against gastro-intestinal nematodes (in 970/o) and pulmonary nematodes genus Dictyocaulus. Clinical examination showed no side-effects of the preparations applied.

Opis:
The experiments were made on 180 hens aged from 1 day to 10 weeks. The animals were infected peroral, subcutaneously or intraperitoneally. The material for infection (RH strain) was used as exudate of mice (trophozoite) or as organs of rats or rabbits infected a year ago (cysts). Investigated was also the possibility of infection in healthy hens through direct contact with diseased ones. The items taken in consideration were as follows: (1) clinical picture, (2) hematologic examinations includimg number of erythrocytes, leukocytes, white cell count, (3) serologic studies using complement fixation and dye tests, (4) effect of food on the mechanism by which hens get infected per os (alkaline, neutral or acid reaction), (5) anatomo-pathologic, microscopic studies and isolation of strain. The results obtained prompt the following conclusions: (1) experimental toxoplasmosis of hens is difficult to induce and the moment of infection food seems to play a major role in the mechanism of infection. The mortality of hens is lower than in other animals infected in the same way and conditions, and even spontaneous cure may occasionally take place; (2) in peroral infection food seems to play a major role in the mechanism of infection. The administration of alkaline food increases the chance of infection; (3) in experimental conditions healthy hens may contract infection from diseased ones through direct contact; (4) hematologic studies do not seem to be of important diagnostic value, whereas the reduction in the number of erythrocytes may indieate an evolution of pathologic process; (5) Serologically (CFT and DT) the presence of antibodies is not an invariable finding, the positive reactions showing comparatively low titres.

Opis:
Serologic examinations were performed in 1605 birds (1200 hens, 200 geese, 100 ducks, 100 turkeys and 5 guinea fowls), healthy from the clinical point of view, of varying race, age and sex; 700 hens came from 8 farms of Wrocław voivodeship, the remaining birds (905) from slaughter-house. The birds killed at slaughter-house were also examined for the presence of parasite by means of passages on mice. Positive serologic reactions (CFT and DT) were obtained only in 11 out of 1200 examined hens and in 2 out of 200 geese (DT). The titres were, however, low amounting to 1:5 or 1:10 in hens and to 1:40 and 1:80 in geese. Attempts at the isolation of Toxoplasma strain were unsuccessful.

Opis:
A new technique (digestion after Jacobs) for isolation of Toxoplasma from experimentally infected hens was compared with the routine method. The experiments, performed in two series, have shown that the chance of obtaining positive results is greater with digestion method. The superiority of the method apparently consists in the fact that larger amounts of the examined specimen are being used. As a result of digestion process there is condensation of Toxoplasma, which in turn increases the possibility of isolation.

Opis:
Forteen cats were used for the experiments, including 6 infected intraperitoneally, 4-perorally, 2-intraconjunctivally, 1-intratracheally, with one animal serving as a control. An acute course of the disease was found in two cats, subacute in three, and chronic in the remaining animals. One cat, infected perorally was found to be free of toxoplasmosis. Clinical picture of the disease, hematologic, electrophoretic, serologic studies and anatomo-pathologic findings are presented. The results obtained prompt the following conclusions: (1) The course of experimental toxoplasmosis in cats is likely to depend on the age, invasion route, and the material used for infecting purposes. (2) The observed clinical symptoms and anatomo-pathologic alterations do not seem to be typical of this disease. (3) Hematologic and electrophoretic studies are not contributory to the diagnosis. (4) The Sabin-Feldman's dye test apparently reflects the course of the disease, whereas the complement fixation test, for unknown reasons, fails, being negative in majority of cases with toxoplasmosis confirmed by other methods.
