An unusual outcome in a child with hepatosplenic cat-scratch disease.

Typical cat-scratch disease (Bartonella henselae infection) in an immunocompetent child is usually associated with a history of scratch, bite or intimate contact with a cat. Most patients develop a non-tender papule in the scratch line after three to ten days. This may persist for only a few days or as long as two to three weeks.

Genetic characterization of wild type measles virus isolated in Croatia during the 2003-2004 outbreak.

Viral epidemiology is determined by the movement of infected people within and between geographical areas. The genetic characterization of wild-type isolates combined with standard epidemiological methods may enable the identification of the source and transmission pathways and permit differentiation between indigenous and imported viruses. We investigated the genetic characteristics of the wild-type measles virus isolated in Croatia during a 2003-2004 outbreak.

Establishment of an active laboratory-based surveillance for bacterial meningitis in Croatia and molecular characterization of Neisseria meningitidis isolates causing meningococcal disease that were collected in the year 2000, the first year of activity.

In 2000, 23 Neisseria meningitidis (meningococcal [Men]) isolates were collected in Croatia through an active laboratory-based surveillance for bacterial meningitis (17 Men serogroup B [MenB], 4 MenC, 1 MenW135, and 1 nongroupable isolate). Molecular characterization revealed a substantial level of diversity with only six isolates belonging to electrophoretic type 5 (ET-5) and ET-37 hypervirulent complexes.

[Neisseria meningitidis with a decreased sensitivity to penicillin in the Zagreb District].

Of the total of 35 clinical isolates from blood and/or cerebrospinal fluid in patients from the Zagreb area in the period from 1996-1999 Neisseria meningitidis serogroup B was identified in 33 (94%). N. meningitidis strains with decreased susceptibility to penicillin have been occurring in Zagreb since 1998, and during the two-year period in this study we isolated 3/19 (16%) such strains (MIC, 0.
