Campylobacters have been isolated in Bangladesh from patients with gastroenteritis, from healthy individuals and animals. A total of 180 Campylobacter isolates, 100 from patients with gastroenteritis reporting to International Centre for Diarrhoeal Disease Research, Bangladesh hospitals, 50 from asymptomatic carriers and the other 30 from domestic animals of the index cases have been characterized following standard procedures available. All isolates tested have been confirmed as Campylobacter jejuni. Irrespective of their source of isolation, Campylobacter isolates showed identical biochemical behaviours. All isolates showed thermophilic characteristics of jejuni/coli group. None of the isolates grew at 25 degrees C. Uniform sensitivity to nalidixic acid, metronidazole, 2, 3, 5-triphenyltetrazolium chloride, resistance to cephalothin was observed; H2S production in all isolates by different methods was confirmed. All isolates from different sources confirmed to be C. jejuni; none of the isolates, even from the animal source could be characterized as C. coli.

During a one-year period, 258 isolates of Campylobacter jejuni and C. coli were obtained from children with gastroenteritis or bacteraemia at the Red Cross Children's Hospital, Cape Town, South Africa. These isolates were biotyped by hippurate hydrolysis, H2S production and tolerance to 2,3,5-triphenyltetrazolium chloride (TTC). Our study indicated that 95.4% of the isolates were C. jejuni biotype 1, 1.5% were C. jejuni biotype 2 and 3.1% were C. coli; 70% of the isolates were resistant to TTC. Serotyping on the basis of soluble, thermostable antigens detected by a passive-haemagglutination technique revealed that 79% of the Cape Town isolates were typable and that the most common serotypes, in order, were: 4, 2, 12, 23/36 and 19, together comprising 25% of the isolates. About 37% of the typable isolates belonged to nine serotypes. The finding that 21% of the isolates were non-typable suggests the existence of antigenic specificities different from those defined by the 60 antisera in current use.

Some properties of 5 H2S+ strains of E. coli (labeled EC1-EC5, of which 4 isolated from the feces of subjects with gastroenteritis and 1 from a patients with cystopyelitis) has been studied. Of these, two resulted to belong to the O140 and one to the O127 serological groups; other 2 strains were found to react respectively with two (O84 and O108) and three (O65, O70 and O71) E. coli antisera. H2S- segregants were spontaneously obtained from 3 of these strans, but with different frequency: it was very low in EC5 (1.4%) and especially in EC3 (0.2%) strains, but appeared higher in EC4 (39.3%) strain. Clones from EC4 strain were also raffinose-negative; 11 of 12 obtained from EC5 strain (resistant to tetracycline) appeared sensible to tetracycline. Only one strain (EC4) has been able to transfer the H2S+ character with 4.7% frequency; another strain (EC5) transferred tetracycline-resistance character, but with lower frequency. Raffinose-positive character has never been transferred.
