ABSTRACT
The isolation of a strain of Bordetella for which the species could not be determined but which most closely resembled Bordetella avium is reported. The strain was isolated in mixed culture from an ear swab of a patient suffering from chronic otitis media. The bacterium showed the typical biochemical reactions of Bordetella avium but differed in antimicrobial resistance pattern, protein and fatty acid composition, and DNA-DNA and DNA-rRNA hybridization. Further studies will clarify the taxonomic status of this strain within the Bordetella-Alcaligenes ribosomal RNA cluster.

We report about four children, who suffered from myositis caused by beta-hemolytic group A streptococci (GAS). The cases were observed during the last 12 months, and differed much in severity. Soft tissue infections caused by GAS are reported with increasing frequency from the USA, Australia and Europe. They occur in hitherto healthy children and young adults, mostly without a predisposing trauma. In children, a preceding varicella infection is often found. Some patients develop a streptococcal toxic shock syndrome with a letality of 20-50%. The bacteria, which can be isolated from normally sterile body sites, are morphologically inconspicuous, and are mostly of the serological type M1 or M3.
