Experiments were conducted on two hematophagous species: Menacanthus stramineus N. and Menopon gallinae L. The Mallophaga gorged with blood, were taken from the chickens from 12 to 24 hours after they had died due to pasteurellosis. Blood was isolated from the struma of the Mallophaga, diluted with physiological fluid and then injected intramuscularly, into the peritoneum and subcutaneously in healthy chickens, chicks and white mice. Pasteurelia multocida was found in the blood of the animals that died due to this infection on the basis of Gram's staining method and on culture medium with sugar. It has been found, that the fowl pasteurellosis bacteria appear in the alimentary canal of Mallophaga already 4 hours after death of the chicken from pasteurellosis. But a greater mortality of the experimental animals is received when they are infected with infectious material from the alimentary canal of Mallophaga that have been taken from the chickens 12 hours of their death. The pasteurellosis bacteria were found in the alimentary canal of the insects that were taken from the dead chickens 120 hours after their death. Mice died in the time from 9 to 24 hours after orally infecting them with ground Mallophaga that were taken from chicken dead on pasteurellosis.
The authors performed 2034 oesophagus dissections in cattle, 2630 dissections in swine and 756 sheep gullet dissections for the presence of Gongylonema pulchrum Molin 1857 in the period from March to the end of December, in the year 1963. As a result of their investigations the authors conclude that G. pulchrum has a frequency of 4.5% in cattle of the Lublin voivodeship, its invasion intensity ranging from 1 to 12 parasites. In sheep the frequency amounts to 1.6%, the invasion intensity being from 1 to 7, per oesophagus. This parasite was never found in swine. In cattle and sheep the parasite was most ofter found in proximal and distal ends of the gullet. No seasonal differences were found as to the extensivity and intensity of this parasite. Clear -cut cases with sings of disease were not found.
The amount of blood taken from hens by bird lice was determined using radioactive chromium as labelling factor. It has been found that the radioactivity of bird lice increased with time, especially in larvae, while at the same time the radioactivity in the hens decreased. The method can be successfuly used for the determination of blood taken by haematophagic insects.
On the background of informations about frequency of appearance Fasciola hepatica L. among cattle in Poland im the time from 1995-1997, as well es in the former period, there is presented in the article an estimative apperiation of economical losses caused by staggers disease among cattle. The highest extensiveness of invasion of F. hepatica L. among cattle was noticed in the fifties and sixties manty in the north-eastern Poland. Losses caused by confiscation of a liver to amounted to 1197031zł in 1995, 1277154zł in 1996 and 1312078zł in 1997.
Cases of taeniosis were mostly caused by Taenia saginata (318 cases – 84.8%). They were more frequently found in urban populations (255 cases, which is 68%) than in villagers (63 cases - 16.80%). Among the studied subjects there were fewer women than men (women - 147, 39.2%, men - 171 - 46.67%); taeniosis was diagnosed most frequently among persons aged 30-39 (89 cases - 23.73%) and only rarely in children aged 0-9 (8 cases – 2.13%). From 1986 through 1994 cysticercosis caused by Cysticercus bovis was found in 1684 (0.018%) animals of 934202 heads of cattle slaughtered in Katowice district. That particular cysticercosis was observed each year. During the period 1986-1994 cysticercosis caused by Cysticercus cellulosae was found in only few pigs (6 cases - 0.0001 % of 5930961 examined pigs). In the same period of time echinococcosis was found in 196711 pigs, which is 3.3% of 5930961 examined animals.
The authors showed the frequency of occurrence of trichomonadosis and candidosis in 31 842 women living in the Upper Silesia territory. The most extensive invasion of T. vaginalis and C. albicans was found in autumn, and in women 24-34 years old.
The autors present an extensiveness of invasion of hydatidosis among swine in Poland. It is ascertained that a hydatidosis among swine appeared most often in the Eastern Poland. The analysis of these data shows that the percent infected animals, the highest extensiveness of invasion hydatidosis among swine occur in the districts Zamość, Łomża and Chełm.
