The antimicrobial susceptibility of 30 clinical and 30 food Bacillus cereus isolates was determined. All isolates were susceptible to streptomycin, ciprofloxacin and gentamicin, 90 % of them to clindamycin and vancomycin, and 67 % to erythromycin. All isolates were resistant to amoxicillin with clavulanic acid, ampicillin, cefotaxime, ciprofloxacin, cloxacillin, cefotaxime with clavulanic acid and penicillin. The MIC values (determined by E-tests) were 48-256 mg/L for ampicillin, 0.19-1.5 mg/L for gentamicin, 0.125-1.0 mg/L for clindamycin, 0.047-4.0 mg/L for erythromycin and 1.5-16 mg/L for vancomycin. The MICs 4.6-18.75 g/L were observed for penicillin using the microdilution method. The presence of metallo-beta-lactamases was detected by E-test for 100 % of strains. Nonhemolytic diarrheal enterotoxin (NHE) was produced by 98.3 % of strains, while 31.7 % of them produced hemolytic diarrheal enterotoxin (HBL). Clinical isolates produced 10 % more HBL than food isolates. The psychrotrophic strains isolated from food samples produced NHE at 6.5 degrees C in 73 % of cases.

To establish current seroprevalence of human T cell leukaemia/lymphoma virus type I (HTLV-I) infection in some low- and high-risk populations from Slovenia, 10,369 and 869 serum samples collected during Slovenian 1994 unlinked surveys of human immunodeficiency viruses seroprevalence in pregnant women and patients attending venereological outpatient services, respectively, and 219 serum samples collected from Slovenian intravenous drug abusers during 1995 and 1996, were screened for the presence of anti-HTLV-I antibodies using commercial particle agglutination test Serodia HTLV-I (Fujirebio, Tokyo, Japan). Only one sample obtained from a pregnant woman was found repeatedly positive in the screening test. Presence of anti-HTLV-I antibodies in the reactive sample was undoubtedly confirmed with supplemental Western blot test. The prevalence of antibodies to HTLV-I in the Slovenian population might be somewhere between one in 10,000 (0.01%) and one in 15,000 (0.0066%), which is similar or even higher to prevalence rates in other European countries.

Four most widely accepted genotyping methods for hepatitis C virus (HCV) were applied to 40 HCV RNA isolates obtained from Slovenian patients in order to determine the concordance and applicability of various genotyping systems. The four methods are: (i) amplification of the core region with genotype-specific primers; (ii) nested polymerase chain reaction (PCR) in the core region followed by hybridization to HCV type-specific probes; (iii) reverse hybridization with the line probe assay Inno LiPA (Innogenetics, Gent, Belgium) using type-specific probes for the 5' non-coding region (NCR); and (iv) restriction fragment length polymorphism analysis of DNA amplified from the 5' NCR. Additionally, in isolates with discordant results nucleotide sequence analysis of a part of the NS-5 region was performed. Both genotyping methods based on the analysis of the 5' NCR were found more sensitive than those methods based on the analysis of the HCV core region. None of the four genotyping methods correctly classified all Slovenian HCV RNA isolates. PCR with genotype-specific primers was identified as entirely unsuitable for genotyping of Slovenian HCV RNA isolates. The remaining genotyping methods could clearly differentiate between HCV genotypes, but were not entirely reliable for HCV subtyping. The specificity of genotyping methods, which are based on the 5' NCR or the core region, was occasionally hampered, due to a lack or excess of sequence variation in their respective target regions.

Enzyme immunoassays are most widely used screening tests for antibodies to human immunodeficiency viruses (HIV). Nevertheless, the need of simpler, noninstrumented tests is evident in many parts of the world, where laboratory facilities and trained personnel are limited, and HIV incidence is high. A recently developed variant of gelatin-particle agglutination tests, Serodia HIV-1/2 (Fujirebio Inc., Tokyo, Japan), is one of such simple and noninstrumented tests. To evaluate its utility, 3311 serum samples (281 anti-HIV-1 positive, 8 anti-HIV-2 positive and 3022 anti-HIV-1/2 negative) obtained from 2632 individuals from Slovenia, other parts of former Yugoslavia and Senegal were investigated. No false-negative results and only one false-positive result were obtained during the procedures, giving overall sensitivity and specificity of the particle agglutination test of 100% and 99.97%, respectively. We have concluded that Serodia HIV-1/2 test is highly specific and sensitive for detection of anti-HIV-1/2 antibodies, suitable for small blood banks and for epidemiological surveys.
