Background: Emergence of erythromycin (Er) and clindamycin (C) resistance (R) observed in GBS, is currently becoming recognized. Methods: Clinical isolates were obtained from a Belgian surveillance for invasive GBS disease in newborns and adults in 1996-1998 (N1=235) and from consecutive specimens submitted, during 1999-2000, to the University hospital of Liege (N2=165). MICs of Er were determined buy using Etest® strip (interpretive criteria of NCCLS). Furthermore, for the ErR isolates, the inducible (iMLS), constitutive (cMLS) and M phenotypes were assessed by disk diffusion and by a double-disk test; the distribution of genes encoding RNA methylases and efflux pumps was investigated by PCR. Results: Of the N1 and N2 isolates, 16 (6.8%) and 19 (11.5%) were respectively R to Er. Among these 35 ErR isolates, 21 (60%) exhibited the cMLS phenotype. They demonstrated a high level R to Er with MICs ranging from 16 to >256 mg/L. The ermB gene was harbored by 19/21 isolates, the ermTR gene by 1 isolate and both ermB and ermTR were present in another isolate. The iMLS phenotype was observed in 10 (29%) ErR isolates; the ermTR gene was present in all isolates except one harboring an ermTR gene. These strains demonstrated low level of R to Er, with MICs of 1-12 mg/L. All 4 isolates (11%) expressing an M phenotype, displayed low level R to Er alone (MICs, 2 mg/L) and were positive for the mefA/B gene. Conclusion: In Belgium, by year 2000, prevalence of R to macrolide in GBS exceeded 10%. R was mainly caused by target-site modification (ermB, ermTR) mechanisms; efflux (mefA/B) R mechanism was also prevalent among the isolates tested. These results indicate the possibility of inappropriate prophylaxis or therapy using C or E as the recommended alternatives in penicillin-allergic patients. [less ▲]

Background : Recently, a novel blood-borne virus has been identified and named hepatitis G virus. Transfusion is the main route of transmission. It is known that patients on maintenance dialysis are more susceptible to infections with parenterally-transmitted viruses than the general population. The aim of the present study was to determine the prevalence of hepatitis G infection in a Belgian dialysis unit. Methods: The entire population of our dialysis unit (82 patients) was tested for the presence of hepatitis G virus (HGV) by reverse transcriptase polymerase chain reaction. History of transfusion or renal transplantation coinfections with hepatitis B and C viruses, and serum aminotransferase levels were also tested. Results: Thirteen patients (16%) were found positive for HGV-RNA. Among these patients, 69.2% were infected by the G virus alone, 15.4% were coinfected with B virus, and 15.4% with C virus. All but one patient had a history of transfusion. Ten of the thirteen infected patients (77%) had normal aminotransferase (< 30 UI/l). Three patients had elevated aminotransferase levels (23%); one was coinfected with B virus, one with C virus, and the last one had a diabetes-induced fatty liver infiltration. No liver biopsies were performed. Conclusions :It is concluded that infection with C virus is common among dialyzed patients. This high rate of infection could be related to previous transfusions, but may as well be due to nosocomial transmission. In our series, at least one patient has been contaminated by another road than transplantation or transfusion. Finally, it does not appear clearly that chronic infection with hepatitis G virus induces Liver disease, as defined by elevated aminotransferase level. [less ▲]

Porcine reproductive and respiratory syndrome (PRRS) causes major economical losses in pig farms. In different parts of the world, there is a growing consensus that PRRS virus (PRRSv) eradication should be performed on a regional basis, particularly in low density areas of pig production. The objective of the present study was to evaluate the apparent prevalence of PRRSv in Wallonia, a low density area of pig production (0.05 pig farms/km²). At this stage of the study, a phone survey has been addressed to 61/276 Walloon breeding pig owners. Fifty-eight answered to the questionnaire: 51 are responsible of a farrow-to-finish farm, 6 of a farrowing farm and 1 of a PRRS-free boar station. In 35% of the tested farms, sows are vaccinated with a modified live virus (MLV) PRRS vaccine (n=11) or with a killed PRRS vaccine (n=9). In two farms, both sows and piglets are vaccinated with a MLV PRRS vaccine. Replacement gilts are purchased in 33% farms. Among the 38 farms raising replacement gilts, 39% purchase boar(s). Boar semen is purchased in 86% of the farms: 56% purchase only boar semen; 30% purchase both semen and boar(s) and 14% of farms only purchase boar(s). In 22/57 tested farms, clinical signs evocative of PRRSv infection were observed over the last 10 years. In 30 farms a PRRS diagnostic test was performed in the past with a positive result in 17. When the pig owner did agree and if no vaccination was carried out on sows or on piglets, a serological Elisa test was performed in 10 breeding pigs and/or 5 feeder pigs >70 kg (or in all available sera if a smaller number of pigs was present). Globally, at herd level and at animal level, the apparent prevalence were respectively 35.2% (95% CI: 23.0-47.4%) and 23.4% (95% CI: 20.1-26.6%). [less ▲]

Radiographic screening of horses prior to purchase or admission to studbooks has become an important tool for evaluating the osteo-articular status of the animals. Developmental orthopedic disorders (DOD) are the main cause of potential lameness in youngsters. The genetic factor associated with DOD has been established, and specific selection schemes have been developed to diminish the prevalence of lesions. Increasing knowledge of prevalence in different breeds may help in developing specific breeding strategies. This article presents the results of the radiographic screening of 676 stallions presented for sire admission to the Royal Belgian Sports Horse Society (Studbook sBs). On average, two radiographic findings were noted per horse. The prevalence of DOD in this population was 38.9%. A high percentage of horses showed radiographic signs of effusion of the distal interphalangeal joint. An uncommon fragment location at the proximal tubercle of the talus was found in 7 horses. The present paper presents a review and discussion of all the radiographic findings. [less ▲]

Salmonella species infections of male mule ducks were studied for 32 months in 100 flocks on nine duck farms in Belgium. The prevalence of Salmonella species infections changed significantly over time (P<0.001) with infection rates of 50, 13.4, 6.7, 2.6 and 2.9 per cent, respectively, at the time of arrival on the farm, at three, six and nine weeks of age, and when the ducks left the breeding unit to enter the force-feeding rooms (at 11 or 12 weeks of age). During the study period, 95 strains of Salmonella were isolated, belonging to 11 serotypes. S Indiana (42.1 per cent) and S Regent (36.8 per cent) were the two most common serotypes, whereas S Typhimurium and S Enteritidis were found only once (1.1 per cent). All isolated strains were resistant to at least two antimicrobials, but resistance to more than five antimicrobials was observed in 21.6 per cent of the strains. [less ▲]
