RESUMO
The higher incidence of HB8Ag/ayw (71%) in sera collected from acute viral hepatitis cases, as well as from patients with chronic active hepatitis, healthy carriers and blood donors of 20 Romanian counties emphasizes the local prevalence of the ayw determinant in our country.

The results of subtyping the B antigen in 551 sera from patients with viral hepatitis, chronic evolutive hepatitis and cirrhosis, chronic carriers, donors and healthy subjects, were confirmed as positive HBAg by diffusion in agar, counterelectrophoresis and radioimmunology, and characterized by the d-y and w-r determinants by rheophoresis. The high incidence of the y determinant in all nine counties investigated probably reflects the prevalence of this serotype in Romania, recalling the distribution of subtypes observed in the south of Europe.

In August-October 1973 several NAG vibrio strains were isolated for the first time in our country from clinical cases of acute intestinal disturbances. The patients were admitted to hospital being clinically suspect of dysenteric syndrome or alimentary toxiinfection (nausea, vomiting, abdominal colics, tenesms, mucosanguinolent stools, aqeous stools from 4-5 up to 20 in 24 hours, with signs of dehydration). NAG vibrios were isolated from all the cultures in, practically, pure cultures. Epidemiologic survey in the village of B resulted in isolation of the same NAG vibrio strains from the samples collected from the direct contacts and drinking water sources. Therefore, NAG vibrios can unquestionably cause a diarrheic disease and it will be necessary to extend the bacteriologic diangosis also in this direction in all cases of diarrhea of "unknown etiology".
