Antibodies to seven rotavirus serotypes in cord sera, maternal sera, and colostrum of German women.

Forty percent of colostrum samples from German women showed neutralizing antibody titers of greater than or equal to 50 to rotavirus (RV) serotypes 1, 3, 4, and 6. Antibody to serotypes 2, 8, and 9 was less prevalent. Titers are, however, too low to indicate an important effect of colostrum on the RV vaccine take rate.

An outbreak of Acinetobacter calcoaceticus infection in a neonatal care unit.

Between January and December 1988, 383 neonates were admitted to our neonatal intensive care unit. 1,991 swabs and blood cultures were tested bacteriologically. Among them 90 specimens obtained from 41 patients were positive for Acinetobacter calcoaceticus.

Seroconversion patterns to four human rotavirus serotypes in hospitalized infants with acute rotavirus gastroenteritis.

We studied rotavirus-specific antibodies in paired sera from 71 hospitalized infants with acute rotavirus gastroenteritis. Most of the infants were less than six months old. Infants with serological evidence of a secondary rotavirus infection were excluded.

[Effect of various weather parameters on the incidence of inpatient treated children with stenosing laryngotracheitis (pseudocroup)].

A total of 1470 hospitalized children with croup in the cities of Bochum and Herne were examined over a period of 19 years, with the aim of checking whether there was any relationship between croup incidence and changes in different weather parameters such as temperature, air pressure, absolute and relative air humidity, and wind speed. The incidence of croup was seasonal, being higher in the months of January, February, and March and from September to December. Statistical evaluation by discriminant analysis, t-test and chi 2-test showed a significant correlation (alpha greater than or equal to 0.
