[Mycoplasma pneumoniae epidemic as zoonosis]. / Mycoplasma pneumoniae járvány, mint zoonosis.

At a secondary school in Budapest, in the first class, 30 students became sick with fever and upper respiratory catarrhal symptoms between September 19 and October 31, 1995. Two children were hospitalized with a diagnosis of pneumonia, in case of the two children treated at the Szent László Hospital, suspect of Mycoplasma infection raised which was also confirmed by cold agglutination test. During the epizootiological examination on the spot they found a terrarium in the classroom where the students raised a Syrian gold hamster family. Mycoplasmas were isolated from the lung samples of the hamsters during the pathological examination which proved to be Mycoplasma pneumoniae. Owing to the close etiologic relationships between epidemiological anamnesis, characteristics of the epidemic, as well as findings of patients and pathological or histological findings in the hamsters together with the results of bacteriological examinations, the epidemic should be considered as a zoonosis.

[Experience with the screening of pregnant women for hepatitis B virus and the vertical transmission of the virus]. / A terhesek hepatitis B szürésével és a vírus vertikális transzmissziójával szerzett tapasztalataink.

The authors started the checking for the hepatitis B virus in pregnant women of the town Ajka and its surroundings 10 years ago and then they extended it over the whole county. They examined 33,433 pregnant women from 1980 to 1990 and found that 0.5% of them were HBV carrier state (that is 169 persons), while in endemic territories they found a higher rate (0.74%). The existence of vertical transmission can be proved by the positive data of 120 infancy born to 72 symptomless HBV carrier mothers. The frequency of transmission is 4%. At the beginning of the check-up they gave passive then active-passive immunisation to the children born to carrier mothers. The results of immunisation were controlled by clinical and laboratory tests. They suggest that their worked-out check-up and care model--which is unique in Hungary in its kind and is also a part of the programme to prevent cancer--should be introduced all over the country.
