Stool samples obtained from 594 Senegalese patients were examined for characterization of pathogenic Escherichia coli in human immunodeficiency virus (HIV)-related diarrhea. Multiple virulence genes were observed in stool samples obtained from HIV-infected patients with diarrhea. Enteroaggregative E. coli and enteroinvasive E. coli were present in stool samples obtained from patients with diarrhea significantly more often than in stool samples obtained from patients without diarrhea (P=.000001). Quinolones may be an effective alternative treatment for E. coli-related diarrhea in HIV-infected adults in Senegal.

Abstract. The distribution of Hepatitis GB-C/HG (GB-C/HG) and TT viruses (TTV) infections was investigated in selected populations from Gabon using Polymerase Chain Reaction (PCR) and Enzyme Linked Immunosorbent Assay (ELISA) for anti-Envelop 2 (anti-E2) GBV-C/HGV antibodies. Among pregnant women, 29 of 229 (12.6%) were Hepatitis GB virus-C and Hepatitis G virus (GBV-C/ HGV) RNA positive (ϩ) and 32 of 81 (39.5%) anti-E2 ϩ versus 8 of 39 (20.5%) TTV DNA ϩ. Among sickle cell anemia patients, 9.7% (3/31) were GBV-C/HGV RNA ϩ versus 22.5% (7/31) TTV DNA ϩ. For tuberculosis patients, the figures were 11.5% (4/35) and 0%. A study of hepatocellular carcinoma cases (n ϭ 27) versus controls (n ϭ 66) did not show significant differences for GBV-C/ HGV RNA (10.7% versus 12.1%) and TTV DNA (44.4% versus 30.3%). According to phylogenetic analysis, the 15 GBV-C/HGV strains investigated clustered in group 1, the most common in sub-Saharan Africa whereas TTV sequences (n ϭ 4) mostly clustered in genotypes G1 and one close to genotype G3. In the Gabonese populations investigated, GBV-C/HGV and TTV infections were highly endemic. These data are consistent with the low pathogenicity of these agents.
