A probable new Helicobacter species was isolated from the blood of a 14-mon
th-old aboriginal child who presented with vomiting, diarrhea, fever, and d
ry cough. The most similar 16S rRNA gene sequence was that of Helicobacter
fennelliae CCUG 18820(T) but the new sequence differed from it by at least
32 base substitutions and by the presence of a large (353-nucleotide) inter
vening sequence.
