A. xylosoxidans should be considered a potential pathogen in patients with SSTIs, especially in patients with vascular diseases or after surgery or trauma. A history of contact with water should be investigated in all cases. Treatment can be difficult due to the high level of antibiotic resistance. Trimethoprim-sulfamethoxazole may be useful for treatment in outpatients with community-acquired infections.

The aim of this study was toevaluate the prevalence of TT virus (TTV) in 107 hemodialysis patients and 100 healthy individuals. Sixteen percent of hemodialysis patients and 2% of the control population were TTV positive (P<0.001). Sex, time on dialysis, transfusions, and alanine aminotransferase levels were not related to the presence of TTV DNA. TTV was more frequent in patients 50 to 70 (12/51) years of age and persisted in the serum of six of nine patients 8 months later. TTV was found in peripheral blood mononuclear cells of all patients with chronic infection, and sequence variation was noted in the peripheral blood mononuclear cells of two patients. No relationship between TTV infection and hepatitis was observed. Viral persistence and nonparenteral transmission may be possible in patients on hemodialysis.

A study of the distribution of HIV-1 subtypes in the native and immigrant populations of Eastern Andalusia (Southern Spain) was conducted to determine any changes between 1983 and 2001 and to identify antiretroviral resistance mutations in non-B subtype strains among the immigrant population. The study included 111 native patients from Eastern Andalusia: 94 infected with HIV before 1996 and 17 infected since 1996. A parallel study was conducted on 26 HIV-positive immigrants from Africa. Subtyping was done with the heteroduplex mobility assay. Resistance mutations were determined by line probe assay. A total of 137 patients were studied: 9.2% had subtype A (n = 12), 80.8% subtype B (n = 105), and 1.5% subtype C (n = 2). Among the Eastern Andalusia population infected before 1996, 10.9% had non-B subtypes, compared with 23.5% of those infected after that year. The greatest percentage of non-B subtypes (52.4%) was found among the immigrant population. Resistance mutation K70R was detected in one of the six immigrants with non-B subtype and M41L in another. There has been a slight increase in the diversity of HIV-1 subtypes in Eastern Andalusia over the past few years, possibly influenced by non-B subtypes introduced by immigrants from sub-Saharan Africa.
