  Extrinsic contamination of propofol is thought to be a source of postoperative sepsis. Researchers studied growth of Staphylococcus aureus, Pseudomonas aeruginosa, Escherichia coli and Candida albicans in propofol, thiopental and in a 1:1 propofol-thiopental mixture. All microorganisms were taken from standard stock cultures. Half of the samples were incubated at 20°C and the rest were stored at 4°C for 120 h. Growth of microorganisms in each solution was compared by counting the number of the Colony-Forming Units (CFUs) at 0, 3, 6, 24, 72 and 120 h. Propofol supported the growth of all four microorganims at both temperatures. In contrast, thiopental and the 1:1 propofol-thiopental mixture exhibited markedly bactericidal properties on E. coli, C. albicans and P. aeruginosa and bacteriostatic effect on S. aureus.

  Aim:This study was carried out in order to determine the nasal carriage of Staphylococcus aureus and the faecal carriage of Salmonella spp., Shigella spp., Yersinia enterocolitica, Listeria monocytogenes, and Escherichia coli O157:H7 in food industry workers.
Materials and methods: During the study, face to face interviews were conducted with the workers and 9-item questionnaires regarding demographic information, working time, and periodical medical examinations were administered. In the study nasal swab specimens of 1115 individuals and faecal specimens of 1061 individuals were bacteriologically investigated.
Results: The nasal carriage of methicillin-resistant Staphylococcus aureus (MRSA) was found to be significantly more common in the workers who have no health insurance and who never had a medical and bacteriological examination for carrier screening (P < 0.05).
Conclusion: This result supports that periodical health examination is a necessity for food industry workers.

  Aim: To determine the distribution of macrolide resistance genes as well as resistance rates in isolated Streptococcus pneumoniae strains from the southern Marmara region of Turkey. Materials and methods: Antimicrobial resistance rates and MIC values were determined by the E-test method in 300 Streptococcus pneumoniae isolates that were isolated from clinical samples. Resistance genes were determined by the polymerase chain reaction (PCR) method in erythromycin-resistant strains. Results: It was found that 11.4% of Streptococcus pneumoniae isolates were resistant to macrolides. The penicillin MIC value was ≥0.12 μg/mL in 23% of the strains and 2 7mu;g/mL in 2% of the strains. The erm(B) genotype was observed in 58.8% of all macrolide-resistant strains, 38.2% were of the mef(A) genotype, and 3% were a combination of both genotypes. Conclusion: Based on the data from this study, it was concluded that the local resistance to antibiotics is not as high as that observed in other countries, and the erm(B) genotype was dominant in macrolide-resistant strains. Therefore, it is suggested that macrolide-group antibiotics still be included in treatment protocols.

  Burkholderia cepacia and Aeromonas hydrophila infections are described in an African Grey Parrot (Psittacus erithacus erithacus) that presented with neurological signs, lassitude, and respiratory distress. At postmortem examination, subperiosteal ecchymotic hemorrhages in the skull, and severe subcutaneous edema in the neck and abdomen were prominent. Round, disseminated, whitish necrotic foci were noted in the congested liver. Microscopic examination revealed chromatolysis in brain neurons. Multifocal coagulation necroses were found in the liver. Non-purulent, subacute myocarditis, thromboembolic nephritis, and interstitial pneumonia were observed. Microbiological examination revealed mixed cultures of Burkholderia cepacia and Aeromonas hydrophila in brain, lung, liver, kidney, and heart samples.

  A systemic infection with Streptococcus equi subsp. zooepidemicus is described in a 22-day-old female foal for the first time in Turkey. Clinically the foal was in poor condition and had severe pneumonia. Painful swellings of the carpal and tarsal joints were evident. Examination of the dam revealed clinical mastitis. Postmortem histopathological and microbiological examinations of samples from the foal revealed a disseminated infection with S. equi subsp. zooepidemicus. The causative agent was also recovered in pure culture from a milk sample of the mare.
