At the Danish Veterinary Laboratory @entity11769 infections in @entity1707 were diagnosed in 114 cases in 1995 and in 151 cases in 1996. Isolates were serotyped using specific antisera against type 1 through 28 and a total of 67 cases from 1995 and 113 cases in 1996 were tested for resistance to 11 antimicrobial agents. The majority of cases were @entity358 (57%), followed by @entity295 (16%), @entity693 (15%) and @entity884 (8%). Almost 96% of the isolates could be typed using the 28 antisera. The most common serotype was serotype 2 (29%), followed by serotype 7 (17%), and serotypes 3, 4 and 8 (9-10%). The remaining serotypes were observed in frequencies of less than 5%. Serotype 7 was more commonly isolated from @entity295 than the other serotypes. Serotype 2 was more commonly isolated from @entity1707 older than 4 weeks compared to the other serotypes. Most isolates were susceptible to @entity115 + @entity798 , @entity869 , @entity21563 , @entity14116 , @entity114 , @entity6760 , @entity11181 and @entity206 + @entity4766 . A high frequency (> 30%) of resistance to @entity803 was observed. Among isolates of serotype 2, 9.7% were resistant to @entity6186 and 12.9% to @entity7912 . Among other serotypes 56.8% were resistant to @entity6186 and @entity7912 . The differences in susceptibility between isolates of serotype 2 and the other serotypes were statistically significant. Compared to a previous Danish study the distribution of serotypes of @entity11769 causing infections among @entity1707 in Denmark has changed during the last 15 years.
